Description

Reconnaissance device suitable for be covered with miscellaneous filling soil or building rubbish filling site

Technical Field

The invention relates to the technical field of engineering exploration, in particular to a method for surveying a site covered with a miscellaneous fill layer and a plain fill layer rich in construction waste and a matching device used in the method.

Background

The exploration means widely adopted in the building engineering comprises two types of static exploration and drilling. The static probe is one of in-situ test means, can provide diversified data, and has very obvious effect and effect in the aspects of exploration cost, construction efficiency and the like.

The advantages of objectivity and accuracy of data provided by static exploration, no pollution in construction, high construction efficiency and the like are indispensable in a plurality of exploration means. However, the application of the static exploration method is limited by various conditions of a construction site, and particularly when the field is covered with miscellaneous fill or plain fill rich in construction waste, the static exploration method cannot be applied. Generally, the thickness of the filling soil reaches 3 to 5 meters, dust pollution is generated during cleaning, the cleaning cost is high, and in the past, a static exploration means is abandoned and drilling is used instead. If a large removal area is encountered, newly planned buildings are more, the exploration workload is large, but the exploration workload is limited by a site building garbage covering layer, a static exploration means cannot be adopted, and a building garbage layer is often required to be cleaned in advance.

The thickness of the filled soil is considered to be generally 3 meters to 5 meters, but at present, the underground space is generally utilized by the building, and the foundation burial depth also reaches about 5 meters. In other words, the support layer is generally downward about 5 meters. Because the filling layer has little influence on the building, static exploration data of the filling layer is not required to be provided in the construction. Therefore, the patent innovatively designs a method for surveying a site covered with a miscellaneous fill layer or a plain fill layer rich in construction waste on the upper part of a bearing stratum, and designs a matched device/mechanism in the surveying method.

Detailed Description

The structures, proportions, and dimensions shown in the drawings and described in the specification are for the understanding of those skilled in the art, and are not intended to limit the scope of the present invention, which is defined in the appended claims, so they are not essential to the technology, and any structural modifications, changes in proportions, or adjustments in size, which do not affect the efficacy and attainment of the same, are intended to fall within the scope of the invention. In addition, the terms "upper", "lower", "front", "rear" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.

The exploration method suitable for the land covered with the miscellaneous fill or the construction waste as shown in figure 1 comprises the following steps:

step 1, creating a (basic) vertical drilling hole in a filling layer 10, and reinforcing the hole wall of the drilling hole to compact the hole wall. In this step, it is ensured that the hole wall is compacted and the borehole 100 is still substantially vertical.

It is not only required that the axis of the drilled hole has good perpendicularity with respect to the horizontal plane, forming a vertical hole rather than a slant/oblique hole, but also that the entire inner wall of the drilled hole is substantially distributed on a cylindrical surface arranged in the vertical direction (with respect to the horizontal plane).

And 2, inserting a wall protection pipe into the drilled hole to prevent the hole wall of the drilled hole from collapsing. The wall protecting pipe inserted into the drill hole is a plurality of single wall protecting pipes which are connected in sequence. Because the thickness of the filling layer 10 is different under different construction site environments, the axial length of a single wall protection pipe can be not completely the same, so that the requirement of the depth below the wall protection pipe in the filling layers with different thicknesses can be met.

And 3, fixing the port of the wall protecting pipe relative to the soil filling layer. Because the single-hole static exploration operation is short in time, the wall protection pipe can be fixed temporarily and simply (the depth of a drilling hole is relatively shallow, and the wall protection pipe is easy to fix).

And 4, aligning a probe rod probe of the static probing equipment to the upper port of the dado tube, and then putting the probe rod probe into the dado tube. When the probe rod probe is extended into the wall protection pipe, a gap is kept between the probe rod probe and the inner wall of the wall protection pipe.

And 5, after the probe rod and the probe head of the probe are completely placed in the wall protection pipe, adjusting the static probe equipment to enable the static probe equipment (the host) to be basically in a horizontally placed state.

And 6, after the static detection equipment is adjusted to be horizontally placed, fixing the static detection equipment on the filling layer, and performing static pressure operation.

And 7, pulling out the static detection tool from the wall protection pipe after the static detection operation is finished.

And 8, pulling the wall protection pipe out of the drilled hole.

In the above method, reference may be made to the operation steps from step 4 to step 6 in the conventional static detection method (the pipe hole of the casing pipe corresponds to a hole created on the construction site), which is not the core innovation point of this patent.

A surveying arrangement as shown in fig. 2-6 can be used in the above-mentioned surveying method for fastening the inner wall of a borehole and for running into a casing pipe.

The investigation apparatus shown in fig. 2 comprises a clamping feed mechanism 1, a hole fixing mechanism 2, a plurality of feed pipes 3 and a plurality of casing pipes 4.

In order to facilitate operation and installation, the feeding pipes 3 can be connected through a thread structure, and the retaining pipes 4 can also be connected through a thread structure. Meanwhile, the lower end of the feeding pipe 3 is also a structure which can be connected with the hole fixing mechanism 2 through a thread structure.

The lower end of only one of the plurality of feeding pipes 3 is connected with the hole fixing mechanism, and then the upper end of the feeding pipe is connected with other feeding pipes.

The clamping and feeding mechanism 1 can clamp the feeding pipe 3, so that the feeding pipe 3 is erected in the vertical direction, and the hole fixing mechanism 2 is gradually fed into a drill hole 100 established on a soil filling layer 10.

The bore hole 100 has an inner diameter which is greater than the outer diameter of the feed pipe 3 and is smaller than the outer diameter of the casing pipe 4. The inner diameter of the compacted borehole 100 (becomes larger and smaller) is not less than the outer diameter of the casing tube.

The two ends of the wall protecting pipe 4 can be in a tapered conical shape. At this time, the threaded connection between the casing pipe and the hole-fastening mechanism, and the threaded connection between the respective casing pipes, can be established by providing a screw ring 41 (see fig. 4) on the end face of the end of the casing pipe.

In the process that the hole fixing mechanism 2 is conveyed into the drill hole 100, the hole fixing mechanism 2 can compact the inner wall of the drill hole 100 section by section, namely, the whole hole wall soil layer of the drill hole 100 is further compacted from top to bottom section by section, so that the hole diameter is increased.

The clamping and feeding mechanism 1 can clamp the wall protection pipe 4, so that the wall protection pipe 4 stands vertically, and the wall protection pipe 4 is gradually fed into the drill hole 100 with the inner wall compacted.

As shown in fig. 2, the clamping and feeding mechanism 1 includes a base 11, four assembly bases 12 (the number of the assembly bases may be an even number of six or more) mounted on the base 11, a stand 13 fixed on each assembly base 12, a first motor 14 capable of driving the stand 13 to reciprocate in a radial direction (a forward direction, a backward direction, a left direction and a right direction in the drawing) relative to the assembly bases 12, a lifting slide 15 and a connecting base 17 matched with the stand 13, and a second motor 16 capable of driving the lifting slide 15 to reciprocate in a vertical direction relative to the stand 13.

In fig. 2, the rear-side stand, the lifting slide, the connecting base, and other components mounted thereon are not shown, and only two left and right stands are shown, but the embodiment shown is one in which four stands 13 are provided.

The first motor 14 and the second motor 16 respectively drive the vertical base to reciprocate relative to the assembly base station and drive the lifting slide to reciprocate relative to the vertical base station through the lead screw slider transmission mechanism. In the illustration, a guide rod 152 is provided between the lifting carriage 15 and the vertical base 13, so as to reliably ensure the lifting carriage to move back and forth in the vertical direction, thereby improving the cantilever condition of the lifting carriage.

The vertical base 13 is made to slide back and forth relative to the mounting base 12, and the purpose of the operation is to selectively move the vertical base toward and away from the feed pipe and the casing pipe (disposed above the drilled hole), so that the vertical base in different radial directions alternately acts on the feed pipe and the casing pipe.

Under the scheme of the patent, the assembling base platforms 12 are required to be arranged at two ends of the same radial direction pairwise, and the radial directions distributed by each pair of assembling base platforms can intersect at the same center of circle. For example, when the number of the assembly bases is four (as shown in fig. 2 and fig. 6), the assembly bases are divided into two pairs, and the radial directions of the two pairs of assembly bases can be intersected to form a cross shape or an X shape; when the number of the assembling base stations is six, the assembling base stations are divided into three pairs, the radial directions of the three pairs of assembling base stations are intersected to form a 'meter' shape, and preferably, the central angles formed by intersection are all 60-degree included angles.

Two first hydraulic cylinder groups 151 are arranged on the lifting slide carriage 15, and the two first hydraulic cylinder groups 151 are arranged alternately up and down so as to ensure that the axes of the clamped feed pipes 3 have better verticality relative to the horizontal plane (even if the clamped feed pipes 3 are in the vertical direction). The first hydraulic cylinder group 151 includes a hydraulic cylinder and a holding arm fixed at an end of a cylinder rod, and an outer side surface of the holding arm is a concave arc surface capable of forming a surface contact matching relationship with an outer wall of the feed pipe 3, as shown in fig. 2 and 6.

The connecting seat 17 is provided with a second hydraulic cylinder group 171, the second hydraulic cylinder group 171 comprises a hydraulic cylinder and an arm fixed at the end of the cylinder rod, and the outer side surface of the arm is provided with a concave arc surface capable of forming a surface contact matching relationship with the outer wall of the wall protecting tube 4, as shown in fig. 2 and 6.

In order to ensure that the clamped feed pipe 3 and the retaining wall pipe 4 are in a vertical direction (i.e. a direction perpendicular to the horizontal plane), as shown in fig. 2, four corners of the assembly base 12 are in supporting connection with the base 11 through hydraulic columns with controllable telescopic lengths. The position of the upper end face of the assembling base station in space is adjusted by adjusting the length of each hydraulic column, and finally the upper end face of the assembling base station is adjusted on a horizontal plane, so that when the pipe is clamped and fed, the axis of the feeding pipe can be in a position basically vertical to the horizontal plane, and finally, the vertical hole vertical to the horizontal plane is drilled in a compact mode.

As shown in fig. 3, 5 to 6, the hole fixing mechanism 2 includes a bottom plate 21, a pressing plate group 22, and a cover plate 23. The pressing plate group 22 comprises a central sleeve and six hydraulic cylinders 221 which are distributed on the outer wall of the central sleeve at intervals, and a pressing plate 222 is fixed at the cylinder rod end of each hydraulic cylinder 221.

The outer side surfaces of the pressure plates 222 are convex cambered surfaces, and the outer side surfaces of the pressure plates 222 can be distributed on the same cylindrical surface all the time, as shown in fig. 5 and 6, along with the expansion and contraction of the cylinder rod of the hydraulic cylinder 221, the outer side surfaces of the pressure plates can be distributed on the same cylindrical surface with different diameters and the same axis all the time.

As shown in fig. 5, the bore hole 100 is initially created in the fill 10, the press plate 222 is shown as having been moved radially outward by the hydraulic cylinder 221, and the outer diameter of the cylinder on which the side of the press plate 222 is located is now larger than the bore hole initially created. After the press plate 222 has forced the bore diameter of the bore hole to the desired size, the hydraulic cylinders 221 are simultaneously retracted (inwardly) until the side of the press plate 222 is at a cylindrical outer diameter smaller than the originally created bore hole diameter. And then the hole fixing mechanism 2 moves downwards to drill a hole (part which is not compacted) for a certain length, and then drives the hydraulic cylinder 221 to push the pressing plate 222 to move outwards in the radial direction, so as to force the hole diameter of the corresponding drilling section to expand and enlarge. And circulating the steps until the whole drilling hole is compacted.

The central sleeve is sleeved on a central pipe on the chassis 21, and the cover plate 23 is fixedly connected with the chassis 21 through bolts and can press the central sleeve on the chassis, so that the pressure plate group cannot move along the vertical direction relative to the chassis and cannot rotate relative to the chassis. The pressing plate 222 extends in a vertical direction by a certain length. The pump station, controller of the hydraulic cylinder 221 may be fixed to the base or cover plate.

The central tube of the chassis 21 is connected with the feed tube by a threaded structure.

The edge of the upper end face of the chassis 21 is provided with an annular flange 211, and the annular flange 211 is provided with guide grooves correspondingly matched with cylinder rods of the hydraulic cylinders. The guide groove has a supporting and guiding function, so that the cylinder rod axis of each hydraulic cylinder can be always kept vertical relative to the central axis of the chassis.

The annular flange 211 with the guide groove is arranged on the chassis 21, so that the stress condition of the cylinder rod of each hydraulic cylinder 221 can be optimized and improved, the cylinder rod axes of each hydraulic cylinder 221 are always kept in the same (horizontal) plane, an obvious upward and downward floating included angle is avoided being formed by the cylinder rod axis distribution surfaces of each hydraulic cylinder in the telescopic change, the pushing and pressing force direction of the pressing plate is ensured to be radial, namely, the compacted drilling hole wall is basically distributed on a cylindrical surface, and the obvious conical cylindrical surface is avoided being locally formed, so that the wall protection pipe can be smoothly conveyed into the drilling hole.

The axis of the feed pipe 3 is aligned in the vertical direction (which can also be understood as the direction perpendicular to the horizontal) in operation with the direction of extension of the borehole.

As shown in fig. 4, six strip-shaped grooves 42 extending in the axial direction are provided on the outer wall of the wall protecting pipe 4, and the strip-shaped grooves 42 are distributed at intervals around the circumference. The number of the strip-shaped grooves is consistent with that of the pressing plates. Each strip-shaped groove 42 can correspond to the gap between two adjacent press plates.

After the inner wall of the drilled hole is reinforced and compacted by the pressing plates, a convex rib along the vertical direction is formed at the gap between every two adjacent pressing plates. After the strip-shaped groove is formed in the outer wall of the wall protection pipe, the wall protection pipe can be arranged in the drill hole in a one-to-one mode through the strip-shaped groove and the convex edges, and smooth operation of inserting the wall protection pipe into the drill hole is guaranteed. Therefore, the width of the groove opening of the strip-shaped groove is larger than the width of the convex edge, and the depth of the strip-shaped groove is larger than the height of the convex edge.

The number of the mounting bases of the embodiments shown in fig. 2 and 6 is four, and the four mounting bases are provided in two radial directions in the front-rear direction and the left-right direction (the two radial directions intersect in a cross shape). At this time, the vertical base 13 is provided with a lifting slide base 15 and a connecting base 17, and the connecting base 17 is provided at a lower portion of the vertical base 13. A slot structure is formed on the base body of the lifting slide seat 15. During the reciprocating movement of the lifting slide 15, the connecting seat 17 can continuously pass through the slotted hole structure. Namely, the slotted hole structure is that the lifting slide seat can move to the bottom of the vertical seat to perform abdicating.

As shown in fig. 6, the hydraulic cylinder of the first hydraulic cylinder group 151 disposed in the left-right radial direction is referred to as a left-right cylinder a151a, and the hydraulic cylinder of the second hydraulic cylinder group 171 disposed in the left-right radial direction is referred to as a left-right cylinder B171 a. The hydraulic cylinder of the first hydraulic cylinder group 151 disposed in the front-rear radial direction is referred to as a front-rear cylinder a151B, and the hydraulic cylinder of the second hydraulic cylinder group 171 disposed in the front-rear radial direction is referred to as a front-rear cylinder B171B. The suspension arms 31 are arranged in the upper end opening of the central tube of the chassis and the end opening of the feeding tube, so that the hole fixing mechanism 2 can be lifted by a crane during operation.

The operation shown in fig. 6 is as follows:

the hole fixing mechanism 2 is lifted to be arranged right above the drill hole 100, the outer diameter of a cylinder on the outer side surface of a pressure plate 222 of the hole fixing mechanism 2 is smaller than the hole diameter of the drill hole, the hole fixing mechanism 2 is slowly placed into the drill hole, the hole wall of the upper port of the drill hole is compacted, in the process, the feed pipe is clamped and erected by a left cylinder A151a and a right cylinder A151a, and the change from the 1 st picture to the 2 nd picture in the figure 6 is shown.

After the hole-fastening mechanism 2 has moved the most axial length of the feed pipe (designated as the first feed pipe) connected to the hole-fastening mechanism 2 into the borehole and the compaction of the section is completed, the second feed pipe is connected to the upper end of the first feed pipe, and the left and right cylinders a151a remain clamped to the upper end of the first feed pipe.

After the second feed pipe is connected, a casing pipe 4 is held by left and right cylinders B171a and corresponds vertically directly above the borehole, see figure 3 of figure 6.

Next, the front and rear cylinders a151B are clamped to the upper end of the second feed pipe, the front and rear cylinders B171B clamp the bulkhead pipe 4, and then the left and right cylinders a151a are disengaged from the first feed pipe and the left and right cylinders B171a are disengaged from the bulkhead pipe 4, as shown in fig. 4 of fig. 6. In the process, the two vertical seats arranged on the front side and the rear side are respectively close to the axis of the drilling hole forwards and rightwards, and then the two vertical seats arranged on the left side and the right side are respectively far away from the axis of the drilling hole leftwards and rightwards. Next, the retaining tube held by the front and rear cylinders B171B can be fed into the tightened borehole until most of the retaining tube is inserted, and the upper end of the retaining tube held by the front and rear cylinders B171B is maintained.

After the outer diameter of the cylinder on the outer side surface of the pressure plate 222 of the hole fixing mechanism 2 is smaller than the diameter of the hole to be drilled, the hole fixing mechanism 2 is continuously put into the hole to compact the hole wall of a certain section below the upper port of the hole, and in the process, the upper end of the second feeding pipe is clamped by a front cylinder A151b and a rear cylinder A b, as shown in figure 5 in figure 6.

After the hole fastening mechanism 2 has moved the distance of the majority of the axial length of the second feed pipe connected to the hole fastening mechanism 2 into the borehole and the compaction of the section is completed, the third feed pipe is connected to the upper end of the second feed pipe, and the front and rear cylinders a151b are still clamped to the upper end of the second feed pipe.

After the third feeding pipe is connected, the other wall protecting pipe (named as the second wall protecting pipe) is connected to the upper end of the wall protecting pipe (named as the first wall protecting pipe).

Then, the left and right cylinders a151a are clamped to the upper end of the third casing pipe, the left and right cylinders B171a clamp the second casing pipe, the front and rear cylinders a151B are disengaged from the second casing pipe, and the front and rear cylinders B171B are disengaged from the first casing pipe 4.

And (4) according to the sequence, alternately replacing and continuously feeding the feeding pipe and the wall protection pipe into the drill hole until the operations of compacting the wall of the whole drill hole and putting the wall protection pipe into the whole drill hole are completed.

The hole-fixing mechanism is finally removed from the borehole through the lumen passage of the casing tube.
