Description

Anti-vehicle-bouncing inspection well

Technical Field

The utility model relates to an inspection shaft construction technical field particularly, relates to prevent bumping car inspection shaft.

Background

In urban road engineering, pipelines such as rainwater, sewage, communication, electric power and the like positioned in the range of a lane and asphalt surface layers around a pipe gallery inspection well are easy to have quality common faults such as overall subsidence of the inspection well and the road surface around the inspection well, overall falling of the asphalt surface or well frame around the inspection well, uneven smooth connection between the inspection well and the road surface, elevation of the well frame and the well lid above the road surface and the like, and the problem of vehicle jumping in the driving process is caused. After the vehicle jumping happens around the well, the vehicle driving load born by the inspection well and the well backfill area is further increased, a vicious circle is formed, and the damage of the area is accelerated.

The existing construction technology for preventing the vehicle from jumping around the inspection well has the following defects:

1. in the actual construction process, due to various factors such as quality awareness, cost consideration and management level, defects often appear in aspects such as backfill materials around the well, water content of backfill materials and tamping times, so that additional settlement of a backfill area around the well is easily increased, and the phenomenon of vehicle jumping on the road surface is caused.

2. In order to avoid common quality problems in the aspect of well-surrounding backfilling, a technical measure that an annular groove is reversely excavated in a certain range (such as 50cm) around a well, the depth of the annular groove directly reaches a cover plate of an inspection well, and then concrete is backfilled to reduce settlement of a well-surrounding area is provided in part of areas.

The annular groove for backfilling concrete around the well is formed by reverse excavation of the backfilled soil which is already rolled. The technical measure can indeed avoid the quality risk caused by the fact that the well backfill area is not compacted, thereby effectively controlling the phenomenon of well skip in a short period.

However, the well backfill concrete essentially expands the volume of the rigid inspection shaft, creating a ring of larger area well backfill around the backfill concrete. The rigidity between the rigid inspection shaft and the flexible roadbed is still in a sudden change condition, and a transition zone does not exist. In the past, under the action of road surface driving load, after the roadbed compacted in the well backfill area naturally subsides, the phenomena of settlement difference and vehicle jumping in a larger range still occur.

Meanwhile, the reverse excavation process of the backfill region around the well is complex, and for an inspection well with deeper buried depth (the cover plate depth is more than or equal to 1.5m), the annular groove of the reverse excavation is in a long, narrow and deep state (the width is 50cm, and the depth is 1.5m), and the one-step excavation molding by a machine is difficult. Or the annular groove is dug into a wide and deep annular groove, or the concrete around the well needs to be dug in layers and poured in sections. Significantly increasing the cost, the operation difficulty and the construction organization (less square amount of single pouring). The complex and fussy process reduces the willingness of the operation team to execute according to the standard process and also improves the management difficulty. Management holes easily appear, and quality hidden troubles are caused.

In addition, for a conventional bricked inspection well with a cover plate depth of 1.5m and a shaft inner diameter of 70cm, 3.96m of backfilled concrete with the depth of 50cm around the well is used³The concrete of (2). The concrete usage is already large without taking into account the overbreak loss. Does not satisfy the green construction concept of material saving and environmental protection.

Therefore, the existing conventional technology for preventing the vehicle from jumping around the well has the following defects:

firstly, the management difficulty of the peripheral tamping standard process is high, and the quality hidden danger is easy to appear.

Secondly, the effect of reducing the poor settlement in a short period is good, and the long-term effect is not obvious.

Thirdly, the standard process of backfilling concrete around the well is complex, the operation difficulty is high, and the cost is increased.

And fourthly, the consumption of concrete is large, and the concept of material saving and environmental protection is not satisfied.

Example 1

The embodiment provides a prevent car inspection shaft that jumps, the inspection shaft is as the underground space of pipeline transfer, control, inspection, and pipeline includes water pipeline, communication pipeline and power line, should prevent that car inspection shaft that jumps can prevent inspection shaft and well week effectively and take place to subside, restraines well lid and well week and appears staggering for can smooth-going transition between road surface and the well lid.

Referring to fig. 1-2, the anti-bouncing inspection well includes a well 100 and an insert 200. The inserts 200 are connected to the wellbore 100 and extend into the well periphery roadbed, a plurality of layers of the inserts 200 are arranged in the wellbore 100 at intervals in the axial direction, and the support range of the inserts 200 increases gradually or decreases gradually from layer to layer, so that the elastic modulus of the well periphery roadbed is decreased from the wellbore 100 to the outside along the circumferential direction of the wellbore 100.

The number of layers of the inserts 200 distributed in layers in the circumferential roadbed of the well from inside to outside in the radial direction of the well bore 100 is gradually reduced, so that the elastic modulus of the inserts 200 in the radial direction of the well bore 100 is gradually reduced, the elastic modulus of the circumferential roadbed of the well is sectionally transited and sectionally reduced from inside to outside, and the change of the elastic modulus is more linear as the section length is shorter.

A supporting belt with gradually changed elastic modulus is formed around the well, so that the settlement around the well is linearly or tends to be linearly distributed, the alternating stress generated when the shaft 100 and the well are transited is avoided, and the smoothness of the pavement is ensured.

It is understood that the elastic modulus of the well-surrounding road base can be gradually changed or stepped, and the more uniform the change, the more linear the amount of settlement along the well circumference in the radial direction of the shaft 100, and the better the smoothness of the road surface.

Further, the insert 200 is formed in a circular ring shape, and the inner ring is connected to the wellbore 100, and the outer diameter of the insert 200 decreases or increases from top to bottom along the axial direction of the wellbore 100, thereby allowing the support range of the insert 200 to increase or decrease layer by layer. In this embodiment, the outer diameter of the insert 200 arranged from top to bottom decreases progressively, that is, the outer diameter of the insert 200 near the road surface is the largest, and the deeper the position where the insert 200 is arranged, the smaller the outer diameter.

As shown in fig. 3, the insert 200 is a mesh, and has a radial grid structure, and includes a plurality of concentrically distributed circular rings, the circular rings are connected by spokes falling on the radial direction of the circular rings, and the distance between adjacent circular rings is equal. Of course, the insert 200 may also have a structure with a uniform grid, that is, a structure with nodes of the grid uniformly distributed, and each grid has the same shape and size. The mesh-shaped insert 200 can ensure that the insert has uniform support strength, can fill the foundation filler around the well with a hollow structure, and is more tightly connected with the filler.

The insert 200 has a certain elastic-plastic/flexible property, and is formed by splicing and lapping rib materials, wherein the rib materials can adopt a galvanized steel strip, a steel-plastic geotechnical rib-adding strip, a polyethylene geotechnical rib-adding strip, a polypropylene geotechnical rib-adding strip, a nylon rope and a glass fiber rope, and the insert 200 can also directly adopt a geogrid.

When filling the roadbed filling around the well, the embedded parts 200 are paved layer by layer, the roadbed filling is backfilled layer by layer, a layer of embedded parts 200 is installed, and a layer of filling is paved to form a roadbed filling layer.

For a road surface with a high requirement for preventing settlement, the insert 200 is provided with a fastening portion 210, and the fastening portion 210 is connected to a roadbed filling layer to adjust the tension prestress of the insert 200. The modulus of elasticity of the subgrade around the well is further improved by adjusting the fastening position of the fastening part 210 on the subgrade, thereby adjusting the tensile force of the insert 200.

The embedded part 200 is designed and prefabricated according to the actual condition of the inspection well structure, is divided into a plurality of standard parts with different specifications, and is directly installed on the shaft 100 when in use, so that the operation is convenient, and the laying quality is easy to control.

In other embodiments, the insert 200 may be a split structure, with a layer of support members attached to the well bore 100 as an insert 200, such as rod supports attached to the well bore 100 in a radial pattern.

In this embodiment, the anti-bumping inspection well further includes an embedded fastener 300, and the insert 200 is connected to the shaft 100 through the embedded fastener 300. The embedded fixing member 300 is directly embedded in the shaft 100 when the shaft 100 is built, and extends out from the outer wall of the shaft 100, and the embedded part 200 is fixed with the shaft 100 by being connected to the embedded fixing member 300, so that the fixing reliability of the embedded part 200 and the shaft 100 can be ensured, and the installation of the embedded part 200 is simplified.

As shown in fig. 4, the embedded fastener 300 has a limiting portion 310 and a connecting portion 320 connected to each other, a plastering layer 400 is attached to an inner wall of the shaft 100, the limiting portion 310 is disposed in the shaft 100 and embedded in the plastering layer 400 and limits the separation of the connecting portion 320 from the shaft 100, and the connecting portion 320 is buried in the shaft 100 and extends into a roadbed around the shaft to be connected with the embedded member 200. The cross section of the limiting part 310 in the axial direction of the shaft 100 is larger than that of the connecting part 320 in the axial direction of the shaft 100, the connecting part 320 is stressed towards the outer side of the shaft 100, and the limiting part 310 is arranged on the inner side of the shaft 100, so that a limiting pulling force is provided for the separation of the connecting part 320 and the shaft 100. The plastering layer 400 is formed by coating mortar on the inner wall of the shaft 100, so that the bond coating effect of the shaft 100 on the limiting part 310 is increased, and the limiting part 310 has better fixity so that the fixing effect of the embedded fixing piece 300 on the shaft 100 is better.

Because the embedded fixing element 300 is fixed on the shaft 100, the sedimentation of the embedded fixing element is basically consistent with that of the shaft 100, meanwhile, the embedded fixing element 300 is connected with the embedded element 200, the embedded element 200 is embedded in the roadbed around the shaft, and the embedded element 200 and the roadbed around the shaft form mutual traction, so that the sedimentation amount of the shaft 100 and the roadbed around the shaft is uniformly transited, and the problem that the road surface is uneven due to the fact that the sedimentation amount of the shaft 100 and the roadbed around the shaft is unequal is prevented.

The shaft 100 is constructed by building blocks 110, and the connection part 320 is embedded between the blocks 110. The shaft 100 is a cylinder, the blocks 110 can be fan-shaped blocks 110, the inner arc of the fan-shaped blocks 110 is used as the inner diameter of the shaft 100, and the outer arc of the fan-shaped blocks 110 is used as the outer diameter of the shaft 100, so that the circular shaft 100 can be easily built. Multiple tiers of sector blocks 110 may be radially built to ensure the thickness of the well bore 100. Of course, the block 110 may also be square.

When the blocks 110 are stacked, the connecting portions 320 of the pre-buried fastener 300 are embedded in the gaps of the blocks 110 and are wrapped with mortar between the blocks 110.

The connecting portion 320 may be a straight connecting portion 320, the stacking surface of the block 110 is a plane, and the connecting portion 320 is sandwiched between two stacked blocks 110.

The stacking surfaces of the building blocks 110 can also form primary-secondary matching, the connecting part 320 is provided with a bending embedded section matched with the primary-secondary matching surface in shape, so that the connecting part 320 and the building blocks 110 have larger contact area, the embedding stability in the building blocks 110 is better, and the bending embedded section also provides a limiting structure for the separation of the connecting part and the building blocks 110.

It can be understood that, since the fixing fastener 300 is a flexible component, the connecting portion 320 of the fixing fastener is correspondingly changed in shape along with the matching surface of the block 110 when the fixing fastener is inserted into the block 110, so as to form a bent insertion section.

The connection part 320 has a straight section connected with the position-limiting part 310 and connected with the insert 200, in addition to the bent insert section, so as to ensure the position-limiting effect of the position-limiting part 310 on the connection part 320 and provide a flat connection structure for the insert 200.

Referring to fig. 5 to 8, the block 110 of the shaft 100 may include two different blocks 110, one of the blocks 110 has a protrusion 111, and the other is a plane, one of the blocks has a recess 112 matching with the protrusion 111, and the other block has a plane, and the protrusion 111 and the recess 112 are oppositely disposed when the two blocks are stacked, so that the two stacked faces are both planes, and the bending insertion section of the connection portion 320 matches with the gap between the protrusion and the recess 112 when the two blocks 110 are stacked, so as to be tightly inserted between the stacked blocks 110. The shape of the convex portion 111 and the concave portion 112 is not limited, and may be a circular arch shape or a zigzag shape, and the number of the convex portions 111 or the concave portions 112 on one surface of one block 110 may be one or more. In order to reduce the cost, the block 110 having the convex portion 111 and the concave portion 112 may be provided at the position where the embedded fastener 300 is provided, and the block 110 having both surfaces thereof may be used at other positions.

Referring to fig. 9 to 10, the block 110 of the shaft 100 may also be a block 110, two surfaces of the block 110 are respectively provided with a protrusion 111 and a recess 112 that can be matched with each other, when the blocks 110 are stacked, one surface of one block 110 having the protrusion 111 is matched with one surface of the other block 110 having the recess 112, and the bending embedded section of the connecting portion 320 is matched with a gap between the protrusion and the recess 112 when the two blocks 110 are stacked, so that the block 110 can be tightly embedded between the stacked blocks 110.

It should be noted that the two ends of the stacked blocks 110 are in plane fit, so that a smooth transition to the limiting portion 310 and the portion connected to the insert 200 can be ensured.

Referring to fig. 11 to 12, in the embodiment, the limiting portion 310 and the connecting portion 320 are circular rings, the connecting portion 320 is connected to the outer edge of the limiting portion 310, and the thickness of the limiting portion 310 is greater than that of the connecting portion 320, or the limiting portion 310 is a flange disposed on the inner ring of the connecting portion 320, when installing, the limiting portion 310 is disposed inside the shaft 100 and can be attached to the inner wall of the shaft 100, a part of the connecting portion 320 is embedded between the building blocks 110, and the other part of the connecting portion 320 extends to be connected to the embedded part 200.

The embedded fixing piece 300 of the circular ring structure and the shaft 100 are formed into more comprehensive, stable and even embedding, meanwhile, a circumferential more comprehensive connection fixing position is provided for the embedding piece 200, when the embedding piece 200 is also in a circular ring shape, the connection between the embedding piece and the shaft is more comprehensive, the fixing effect is better, the connection is simpler, and the annular embedding piece 200 is directly sleeved on the shaft 100 and is fixedly connected with the connecting part 320.

Of course, in other embodiments, the pre-embedded fasteners 300 may be non-circular structures that provide a circular installation location for the inserts 200 by being circumferentially distributed in the wellbore 100.

The pre-buried fixing member 300 may be made of an elastic-plastic/flexible material, such as glass fiber, geogrid, and the like, and may be made of the same material as the embedding member 200. The connection between the connection portion 320 and the insert 200 may be made by means of adhesion, welding, thermal fusion, bolting, etc., depending on the material selected. When the embedded part 200 is connected with the embedded fixing part 300, the embedded part is connected after being overlapped for 5-10 cm.

The above-described roadbed around the well is formed after the filler is backfilled, and is performed in the roadbed backfilling area around the well when the insert 200 is installed, and the roadbed around the well is formed after the filler is backfilled.

The surface layer of the roadbed around the well is provided with a roadbed filling layer, the interval between adjacent embedding pieces 200 is matched with the thickness of the roadbed filling layer, and the embedding pieces 200 are arranged from the bottom surface of the roadbed filling layer until the designed roadbed working depth is 1.5 times. The inserts 200 are uniformly arranged in the roadbed around the well, and the arrangement depth of the inserts 200 can effectively ensure the working strength of the roadbed. The uniform placement of the inserts 200 further ensures that the change in elastoplasticity of the peri-well substrate outward from the wellbore 100 tends to be linear.

The anti-vehicle-jumping inspection well has the following beneficial effects:

(1) the foundation around the well is reinforced by the multiple embedded parts 200, so that certain compensation can be provided under the condition that backfill materials and compaction degree around the well are insufficient, and potential quality hazards are effectively reduced.

(2) A uniform gradient rigidity/elastic modulus transition zone is arranged between the shaft 100 and the roadbed around the shaft to ensure that the settlement value generated by the driving load is linearly distributed in the radial direction of the shaft 100, and the abrupt change of the roadbed elastic modulus is avoided. Even if settlement occurs in the later stage, the asphalt surface layer near the periphery of the well basically has smooth transition without obvious slab staggering.
