Description

Method for filling and pointing ceramic tile joints in tunnel

Technical Field

The invention belongs to the technical field of tunnel construction, and particularly relates to a method for filling and pointing ceramic tile joints in a tunnel.

Background

The brick joint is a gap between two adjacent masonry blocks, wherein the masonry blocks are bricks (sintered bricks), stones, stone plates, ceramic tiles, mosaic, wood boards, glass plates, aluminum-plastic plates and the like, and a plurality of masonry blocks are masonry to form a masonry structure. The joint filling means that a joint mixture (also called joint pointing mixture, filling material, filling mortar, joint filling mortar or joint pointing mortar) is filled into the joint between two adjacent masonry blocks, the joint is filled through the joint mixture, and the joint mixture is filled fully in the joint between two adjacent masonry blocks during actual joint filling. Pointing means that a pointing agent is used for filling and filling a gap between two adjacent masonry blocks, so that the connection between upper, lower, left and right masonry block materials is firmer, and the surfaces of the masonry are clean, neat and attractive. According to different pointing shapes, pointing has four forms of flat joint, concave joint, oblique joint and convex joint. When actually carrying out pointing, not only need accomplish to fill a crack, be about to pointing the gap packing of pointing agent between two adjacent building blocks full, closely knit, the neat and tidy mortar pollution-free in brickwork surface to still need to carry out pointing according to the pointing form of predesigned. The flat joint requires uniform mortar forming in the joint and smooth mortar in the joint, the concave joint with the arc-shaped cross section requires smooth mortar in the joint, and the concave joint with the V-shaped cross section requires clear mortar ridge lines in the joint.

At present, when the brick joints are subjected to joint filling and joint pointing, the mode that the joint filling of the traditional handheld joint filling equipment is matched with the manual joint pointing of an operator is mostly adopted. Currently, there are three major types of electric caulking machines and similar manual caulking machines on the market. The first electric caulking machine and similar manual caulking machines continuously discharge mortar in a storage bin from a mortar outlet to perform caulking by using an electric screw mortar feeding principle, so that the aim of caulking mortar in brick joints is fulfilled. The second electric caulking machine and similar manual caulking machines use the electric hose slurry feeding principle to continuously feed mortar in a storage bin out of a slurry outlet through a slurry conveying hose for caulking, the machine has obvious effect on the grouting and caulking of brick seams with the width of 5-10 mm, the mortar is filled completely, but the mortar still has uneven height and is wavy after the electric slurry feeding caulking machine fills the seams, and manual caulking in later period is still needed. The third electric caulking machine and similar manual caulking machines apply charging power, and adopt an electric push rod to continuously send mortar in a storage bin out from a mortar outlet for caulking, so as to achieve the purpose of caulking mortar in brick joints.

From the above, the three existing electric caulking machines have the following advantages: firstly, filling the slurry more compactly through slurry filling pressure; secondly, filling mortar in mortar joints. But all three have the following disadvantages: the slurry filling material has high fluidity and is easy to deform after slurry filling; secondly, filling the slurry in uneven and wavy form, and needing later manual pointing; thirdly, the mortar for filling joints is easy to overflow from brick joints and pollute brick surfaces (namely the surfaces of masonry blocks or masonry structures); fourthly, a large amount of mortar is easy to overflow when the brick joints are small, and the mortar is easy to flow, slide and fall off on the vertical wall surface due to the larger fluidity of the mortar when the brick joints are large; fifth, the grout material is wasted due to the high fluidity of the grout and the overflow of the grout. Therefore, the existing electric caulking machine cannot meet the actual caulking requirement and needs later-stage manual caulking.

The manual filling or pointing needs constructors to adopt special filling or pointing tools, the manual inch-by-inch filling and pointing are carried out on the brick joints, and a large amount of labor is consumed; and because the manual control of the operation workers, the quality of the joint filling and pointing is uneven, the quality of the joint filling and pointing is poor, the labor intensity of the operation workers is high, the construction efficiency of the joint filling and pointing is low, and the manual joint filling and pointing can not meet the requirements of large-area joint filling and pointing construction.

In summary, the existing brick joint filling and pointing method and the corresponding electric filling equipment have the problems of laggard equipment, more consumed working hours, large material loss, high labor intensity and the like, and have the problems of different filling and pointing depths, different construction standards, different work efficiency and the like caused by different using methods and operating levels of the filling and pointing equipment, time and labor are wasted, and the construction quality is poor. The method has more prominent problems particularly for large-area brick joint construction, such as the brick joint of the ceramic tile protective layer in a long and large tunnel, the existing brick joint filling and jointing method and the corresponding electric joint filling equipment. The ceramic tile protective surface layer in the tunnel is formed by paving and pasting the lower parts of the side walls on the left side and the right side of the tunnel, and is paved and pasted in the tunnel in a full line, so that the area of the ceramic tile protective surface layer is very large, and in addition, the construction conditions of the tunnel are poor, so that the existing brick joint filling and pointing method and the corresponding electric joint filling equipment are difficult to meet the construction requirements.

step B2, positioning the bucket pointing trolley: translating the bucket pointing trolley to the position of the treated brick joint, supporting the travelling mechanism of the joint filling and pointing trolley 1 on the surface of the masonry structure of the treated brick joint, and enabling the grout outlet 1-3 of the joint filling and pointing trolley 1 to be opposite to the treated brick joint;

step B3, pointing: pushing the bucket pointing trolley to move forwards from back along the treated brick joint, synchronously feeding the filling mortar in the storage bucket 2 into the treated brick joint through the mortar feeding channel in the moving process, extruding the filling mortar fed into the treated brick joint through a rear extrusion strip, and simultaneously carrying out extrusion forming on the outer surface of the filling mortar extruded by the rear extrusion strip in the treated brick joint through a groove pressing wheel 1-5 positioned at the rear side of the rear extrusion strip so as to complete the pointing process of the treated brick joint;

the rear extrusion strip is a mortar extrusion strip 1-4 positioned at the rear side of the mortar outlet 1-3 in the step;

in the step A2 and the step B1, when the processed brick joints are horizontal brick joints, the joint filling and jointing trolley 1 in the bucket joint filling trolley is horizontally arranged and is vertically arranged with the storage hopper 2; when the treated brick joints are vertical brick joints, the joint filling and jointing trolley 1 in the joint filling trolley with the bucket is vertically arranged and is arranged in parallel with the storage bucket 2.

Wherein the filling mortar is a caulking agent, also called as a pointing agent. When the mortar is actually used, mortar or plaster for filling and pointing the brick joints is used.

The processed brick joints are the brick joints of the ceramic tiles processed under the current state.

During actual construction, the masonry structure can be a masonry wall or a masonry column built by bricks (sintered bricks) or stones, or can be a paving layer built by stone plates, ceramic tiles, mosaic, wood boards, glass boards or aluminum-plastic boards and paved on the surface of a wall, a ground or a column. Therefore, the application range is wide. Wherein, the baked bricks, the stones, the stone plates, the ceramic tiles, the mosaic, the wood plates, the glass plates or the aluminum-plastic plates are all masonry blocks.

As shown in fig. 12, the tile paving layer is a tile surface protection layer 12 paved on the lower wall bodies of the left and right side walls of the constructed tunnel 11, and the tile surface protection layer 12 is paved on the tunnel secondary lining 13 of the constructed tunnel 11; the tiles are facing tiles, and the tile facing layer 12 is formed by paving a plurality of facing tiles.

In this embodiment, the constructed tunnel 11 is a sichuan ganzi 317 national-way sparrow mountain tunnel, which is the first high-altitude ultra-long highway tunnel in the world at present. The tunnel site is located on northwest of western altitude of 4300 m, the construction area is high in altitude, bad in climate and high in environmental protection requirement, and the oxygen content and the air pressure value are only 60% of those of the normal value. The tunnel main tunnel length of the sparrow mountain is 7083 meters, the tunnel main tunnel length is 7108 meters, and construction experience under the same conditions does not exist at home and abroad at present.

The efficiency of personnel and equipment is reduced by only 60% of that of plain areas due to the environmental influence of low air pressure and low oxygen content, the problems of improving work efficiency and reducing labor intensity of constructors in the construction of the sparrow mountain tunnel are difficult problems to solve, and the method has the characteristics of high construction difficulty, high safety risk, short construction period and the like. The width of the main tunnel of the constructed tunnel 11 is 9.0m and the width thereof is 5.0m, the width of the horizontal guide and the transverse driving tunnel is 4.5m and the height thereof is 5.0m, and the height of the ceramic tile protective surface layer 12 in the main tunnel of the tunnel is 3.0 m. The ceramic tile surface protecting layer 12 is paved on the tunnel secondary lining 13, the width of a ceramic tile joint is 10mm, and the tile sticking area is 32300 square meters.

In addition, when the ceramic tiles are actually paved on the tunnel secondary lining 13, the quality of the joint filling and the joint pointing of the ceramic tile surface is directly related to the sticking quality of the ceramic tiles, particularly on the plateau with the altitude of 4300 m, the ceramic tiles are easy to fall off due to large environmental temperature difference, and the quality of the joint filling and the joint pointing of the ceramic tile joints is particularly remarkable.

However, the existing brick joint filling and jointing method and the corresponding electric joint filling equipment generally have the problems that only the brick joint filling can be carried out and the manual jointing is needed after the joint filling, the manual jointing has the problems of low work efficiency, high labor intensity, long construction time, poor construction quality and the like, the manual jointing generally has the defect that a large amount of joint filling mortar (namely the filling mortar) overflows, and the situation that the smaller the brick joint is, the joint filling is carried out or the waste of mortar materials for the joint filling is larger correspondingly exists. Moreover, although manual or electric caulking is used, manual caulking is required after the caulking is finished, the labor for putting in the caulking and the caulking is large, the manual caulking effect is poor, and generally 3 persons are required to be put in each day for caulking and 4 persons are required for caulking construction; the labor cost of 7 workers is very high.

The construction of the ceramic tile protective layer 12 in the tunnel construction is a comparatively complicated construction process, the adoption of the invention can effectively reduce the investment of labor force and materials, only 2 workers are needed to complete the joint filling and pointing construction, so the labor cost is greatly reduced, simultaneously, the filling mortar can be automatically flattened, compacted and extruded to automatically complete the joint filling and pointing process, the construction efficiency is greatly improved, the construction period is greatly shortened, the joint filling and pointing quality can be effectively ensured, the waste of the filling mortar can be effectively reduced, and the material cost is saved.

In this embodiment, before the joint filling in step a4 and before the joint pointing in step B3, the brick joints to be processed are cleaned. Wherein, when the treated brick joint is cleaned, the tile paving slurry (namely the tile paving slurry) remained in the treated brick joint is removed.

To ensure that the filling mortar for caulking or pointing is more closely bound to the mortar used in the tile installation, the masonry structure surface is sprayed with water to wet the mortar used in the tile installation in the joints before caulking in step a4 and before pointing in step B3.

The storage hopper 2 is a mortar filling storage device, and considering the requirement that the mortar filling and pointing device carries the filling mortar (namely, a filling material or a pointing material) in the operation process, too many constructors carrying the filling mortar are easy to fatigue, and too few constructors carrying the filling mortar need to frequently fill the mortar and are easy to influence the construction progress; secondly, considering the requirements of the size of the constructed brick joint on the amount of the mortar to be filled, such as: the wider and deeper the seam, the more mortar is carried; the narrower and shallower the seams, the less mortar carry over. Therefore, the capacity of the storage hopper 2 is considered to be both labor intensity of the operator and construction efficiency. Therefore, the number of the storage hoppers 2 is plural, and the capacities of the storage hoppers 2 are all different.

In this embodiment, three storage hoppers 2 with different capacities are used instead. Wherein, the capacities of the three storage hoppers 2 (i.e. the maximum weight of the filled mortar) are 1500 g, 3000 g and 4500 g respectively, so as to be suitable for different use requirements of a construction site.

In this embodiment, storage hopper 2 is the organic glass hopper, and not only the structure dead weight is less like this to can the in-service condition of filling mortar in the visual observation storage hopper 2. In practical use, the storage hopper 2 can also be made of plastic or plastic steel material.

In order to be operated and controlled conveniently, the brickwork joint filling and jointing device further comprises a hand-push device for pushing the filling and jointing trolley 1 and the storage hopper 2 to move back and forth synchronously.

In this embodiment, the cross section of the butt joint 3 is square, and the connection joint 1-2 is a horizontal plug inserted into the butt joint 3 from outside to inside. Therefore, during actual installation, the butt joint 3 of the caulking and pointing trolley 1 is only required to be horizontally inserted into the butt joint 3.

Since the cross-section of the butt joint 3 is square, the connection joints 1-2 are correspondingly square plugs. When the horizontal brick joints are actually filled or caulked, the connecting joint 1-2 of the filling and caulking trolley 1 is horizontally inserted into the butt joint 3, the filling and caulking trolley 1 is horizontally arranged, and the included angle between the filling and caulking trolley 1 and the storage hopper 2 is 90 degrees; when the vertical brick joints are actually filled or caulked, the connecting joint 1-2 of the filling and caulking trolley 1 is horizontally inserted into the butt joint 3, the filling and caulking trolley 1 is vertically arranged, and the included angle between the filling and caulking trolley 1 and the storage hopper 2 is 0 degree. Therefore, the butt joint 3 and the connecting joint 1-2 can simultaneously meet the vertical insertion requirement and the horizontal insertion requirement of the seam filling and pointing trolley 1, and the connecting joint 1-2 and the butt joint 3 do not move radially, so that the connection is more reliable and stable.

In practical use, the connecting joints 1-2 and the butt joint 3 can also adopt cylindrical joints, so that the included angle between the gap filling and pointing trolley 1 and the storage hopper 2 can be any angle, and the gap filling and pointing requirements of brick joints with different inclination angles can be met.

In this embodiment, the rear end of the connection joint 1-2 is provided with a square limiting ring 1-8, which can limit the insertion depth of the connection joint 1-2 into the butt joint 3. The square limiting rings 1-8 and the connecting joints 1-2 are vertically arranged, so that the axial displacement of the connecting joints 1-2 can be limited, and the joint filling and jointing trolley 1 is more convenient and reliable to connect.

In the embodiment, the frame 1-1 is formed by processing an organic glass plate, so that the self weight is light, the strength and the rigidity can meet the requirements of joint filling and joint pointing, and the structure is stable.

During practical use, the mortar pushing mechanism can also adopt other types of pushing mechanisms, and only the filling mortar can be pushed to the mortar conveying channel.

Meanwhile, the joint filling and pointing trolley 1 further comprises a pulp extruding device for extruding the pulp feeding channel and extruding filling mortar out of the pulp outlet 1-3, wherein the pulp extruding device is arranged in the frame 1-1 and is positioned on one side of the pulp feeding channel;

In this embodiment, the squeezing device is a squeezing impeller 5.

The squeezing impeller 5 and the pulp pushing impeller 4 are arranged in parallel and are positioned outside the pulp pushing impeller 4. In practical use, the pulp extruding device can also adopt other types of extruding mechanisms, and only the pulp conveying channel can be extruded to extrude the filling mortar and convey the filling mortar into the treated brick joints.

Therefore, the mortar pushing mechanism is matched with the mortar extruding device, so that the filling mortar can be timely, quickly and continuously fed into the brick joints to be treated.

When the gap filling or the gap pointing is actually carried out, the filling mortar in the storage hopper 2 enters the mortar conveying channel of the gap filling and gap pointing trolley 1 under the pushing action of the mortar pushing impeller 4, and the filling mortar entering the mortar conveying channel enters the treated brick gap under the extrusion action of the mortar extruding impeller 5 and fills the treated brick gap to be flush with the brick surface.

According to the common knowledge in the field, the pointing has four forms of flat joint, concave joint, oblique joint and convex joint. Wherein, according to the different cross section shapes, the concave joint comprises a circular arc concave joint with a circular arc cross section and a V-shaped concave joint with a V-shaped cross section. As shown in fig. 13, when the jointing form of the processed brick joint is a flat joint, the wheel surfaces of the pressure sheave wheels 1-5 are flat surfaces; as shown in fig. 14, when the caulking form of the processed brick joint is an arc-shaped concave joint, the wheel surface of the pressure sheave 1-5 is arc-shaped and the diameter of the wheel surface is gradually reduced from the middle part to both sides; as shown in fig. 15, when the caulking of the brick joint to be processed is a V-shaped concave joint, the wheel surface of the pressure sheave 1-5 is V-shaped and the diameter of the wheel surface is gradually reduced from the middle part to both sides.

The slurry resisting strips 1-7 are in pin joint with the frame 1-1.

In the actual construction process, the operator can observe the storage amount of the filled mortar in the storage hopper 2 at any time and fill the mortar in time. Meanwhile, whether the front and rear pressure sheave wheels 1-5 and the limiting wheel 10 of the gap filling and pointing trolley 1 are opposite to the treated brick joint or not is observed, and the gap filling and pointing trolley 1 is adjusted in time and moves along the central line of the treated brick joint. If the mortar is not full in the brick joints during the operation process, the mortar can be timely fed back.

From the above, in the construction of the highway tunnel, the secondary lining pasting of the ceramic tiles is a key appearance construction structure, the manpower and material resources are greatly input in the whole set of tunnel construction process, the construction period is generally short in the later period of the tunnel construction, the process has high requirements on appearance and pasting quality, but after the ceramic tiles are pasted, the brick joint filling and pointing are carried out, the quality of the brick joint filling and pointing is directly related to the pasting quality of the ceramic tiles, and the brick joint filling and pointing field construction needs to be strictly controlled. The existing brick joint filling and pointing machines and construction methods in the market mainly comprise two types, namely manual and mechanical. The manual brickwork joint filling and pointing equipment has low work efficiency and high labor intensity, is not suitable for large-area brickwork joint construction, and is only suitable for small-area construction.
