Description

Technical Field

[0001] This utility model relates to the field of highway engineering construction technology, specifically to a rapid-construction integral culvert. Background Technology

[0002] Slab culverts, also known as slab culverts, are installed under highways. When the culvert diameter is large and the embankment is high, slab culverts can provide better flood discharge capacity (compared to arch culverts), and their construction is simple and quick.

[0003] Chinese invention patent "A connection structure and method for various components of a prefabricated slab culvert" (publication number: CN113106882A) discloses a technical solution for connecting various components of a slab culvert using grouting sleeves. The grouting pipe end face and the grout discharge pipe end face of the grouting sleeve need to be flush with the side wall of the component (to ensure that the inner cavity of the grouting pipe and the inner cavity of the grout discharge pipe are connected to the outside, thereby facilitating the injection of non-shrink grout). Moreover, the grouting sleeve needs to be set in a double row to improve the tensile strength. However, the grouting pipe end face and the grout discharge pipe end face of the inner grouting sleeve are flush with the inner side wall of the component, and the grouting pipe end face and the grout discharge pipe end face of the outer grouting sleeve are flush with the outer side wall of the component. This causes pouring gaps to appear at the outer side wall of the component (pouring gaps will appear between the exposed grouting pipe / grout discharge pipe end face and the outer surrounding concrete, and pouring gaps will appear between the exposed grouting pipe / grout discharge pipe end face and the inner cavity concrete), which reduces the waterproof performance of the component and shortens its service life. Summary of the Invention

[0004] In order to overcome the problem of "exposed grouting sleeves on the outer wall of the culvert component, resulting in reduced waterproofing performance" in the above-mentioned background technology, this utility model provides a quick-construction integral culvert.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

[0006] A rapid-construction monolithic culvert includes a base component mounted on the upper surface of a foundation and an integrated wall and top component mounted on the upper surface of the base component. The integrated wall and top component includes a top plate and wall panels fixedly connected to each other. Two wall panels are provided, with a second cavity between them. A second exposed horizontal reinforcement bar is provided at the bottom of the second cavity, and both ends of the second exposed horizontal reinforcement bar are fixedly connected to the two wall panels respectively. The base component has a central top surface, and a first cavity is located at the center of the central top surface. A first exposed horizontal reinforcement bar is provided within the first cavity, and both ends of the first exposed horizontal reinforcement bar are fixedly connected to the base component respectively. The first and second exposed horizontal reinforcement bars are fixedly connected by vertical reinforcing bars and cast-in-place concrete. A first exposed longitudinal reinforcement bar is provided on the bottom surface of the wall panels. The base component has a first grouting sleeve and a second grouting sleeve at its central top surface; the first exposed longitudinal rib can be fitted into the first grouting sleeve, and the second exposed longitudinal rib can be fitted into the second grouting sleeve; the wall panel has a first grouting pipe, and the base component has a second grouting pipe, a diversion pipe, and a grout outlet pipe; the top end of the first grouting pipe is connected to the second cavity, and the bottom end of the first grouting pipe can be fitted into and connected to the top end of the second grouting pipe; the bottom end of the second grouting pipe is vertically connected to the middle of the diversion pipe, and both ends of the diversion pipe are connected to the bottom ends of the inner cavities of the first grouting sleeve and the second grouting sleeve, respectively; one end of the grout outlet pipe is connected to the first cavity, and the other end is connected to the top end of the inner cavity of the first grouting sleeve.

[0007] As a further optimization of this utility model, a gap is provided between the base component and the integrated wall top component, and the top end of the inner cavity of the second grouting sleeve communicates with the gap.

[0008] As a further optimization of this utility model, the gap includes an inclined gap; the integrated wall and top component also includes an extension portion, which is fixedly installed at the bottom of the outer wall of the wall panel, and the bottom of the extension portion is provided with an inclined bottom surface; the top of the base component is also provided with an inclined top surface, and the inclined gap is disposed between the inclined bottom surface and the inclined top surface; the top end of the inner cavity of the second grouting sleeve is connected to the inclined gap.

[0009] As a further optimization of this utility model, the first grouting sleeve and the second grouting sleeve are disposed on the side of the first cavity, and the second grouting pipe and the diversion pipe are disposed between the first grouting sleeve and the second grouting sleeve.

[0010] As a further optimization of this utility model, the first grouting sleeve is disposed inside the second grouting sleeve, and the first exposed longitudinal reinforcement is disposed inside the second exposed longitudinal reinforcement.

[0011] As a further optimization of this utility model, the base component is provided with a pre-embedded guide post at the inclined top surface position, and the bottom of the extension is provided with a pre-embedded guide sleeve, and the pre-embedded guide post can be adapted to be inserted into the pre-embedded guide sleeve.

[0012] As a further optimization of this utility model, the base component is a reinforced concrete structure, and a first steel mesh is provided inside the base component. The first steel mesh is fixedly connected to the first grouting sleeve and the second grouting sleeve respectively.

[0013] As a further optimization of this utility model, the integrated wall-top component is a reinforced concrete structure, and a second steel mesh is provided inside the integrated wall-top component. The second steel mesh is fixedly connected to the first exposed longitudinal bar and the second exposed longitudinal bar.

[0014] As a further optimization of this utility model, the outer end of the top surface of the extension portion is inclined downward.

[0015] As a further optimization of this utility model, the base component has an edge top surface at the top, which is located outside the inclined top surface; the center top surface has a first groove, and the inclined top surface has a second groove; one end of the first groove is vertically connected to the top end of the inner cavity of the second grouting sleeve, and the other end is connected to the end of the second groove; the width of the second groove gradually decreases in the direction close to the edge top surface.

[0016] In summary, this utility model has at least one of the following advantages:

[0017] (1) In this utility model, the first grouting pipe, the second grouting pipe and the diversion pipe are used to inject non-shrink grout into the inner cavity of the second grouting sleeve located on the outside. The air in the inner cavity of the second grouting sleeve is discharged through the inclined gap. Therefore, the side of the second grouting sleeve close to the outer wall of the wall panel does not need to be equipped with a grouting pipe and a grout discharge pipe. Thus, the problem of the end face of the grouting pipe and the end face of the grout discharge pipe being exposed from the outer wall of the wall panel will not occur, thereby avoiding the problem of the outer wall of the wall panel having reduced waterproof performance.

[0018] (2) The non-shrink grout overflowing from the first grouting sleeve flows into the first cavity through the grout outlet pipe. The non-shrink grout has the property of occupying space, so the amount of concrete required for the later grouting of the first exposed horizontal bar and the second exposed horizontal bar will be reduced, thereby reducing the amount of material used and saving consumables.

[0019] (3) Thus, the non-shrink grout overflowing from the second grouting sleeve is blocked by the second groove with gradually decreasing width, and cannot flow out to the outside through the inclined gap, thereby avoiding material waste.

[0020] (4) The wall and roof integrated components integrate the wall panels and the roof slab for prefabrication, so only two pouring is required on site (pouring of the base components, pouring of the first exposed horizontal reinforcement and the second exposed horizontal reinforcement). Compared with the three pouring in the traditional technology (pouring of the base components, pouring of the side walls, and pouring between the side walls and the prefabricated roof slab), it can reduce the on-site pouring and hardening time and improve construction efficiency.

[0021] (5) The concrete mortar can flow and fill and seal the horizontal and inclined gaps as much as possible. The non-shrink grout can flow and fill and seal the horizontal and inclined gaps as much as possible. After the concrete and non-shrink grout harden, they can seal the gaps, thereby preventing the water in the backfill soil from seeping in through the horizontal and inclined gaps and improving the service life of this utility model.

[0022] (6) During the lowering of the integrated wall and top component, the pre-embedded guide column and pre-embedded guide sleeve guide the integrated wall and top component and the base component, so that the first exposed longitudinal bar is adapted to be inserted into the first grouting sleeve and the second exposed longitudinal bar is adapted to be inserted into the second grouting sleeve; at the same time, the first exposed longitudinal bar and the second exposed longitudinal bar are prevented from being bent. The operation is simple and the function is reliable.

[0023] (7) The bottom surface of the inner cavity of the culvert is formed by casting the first exposed transverse reinforcement and the second exposed transverse reinforcement, which together with the vertical tie reinforcement form a tight steel mesh, which has excellent structural strength.

[0046] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0047] Reference Figures 1-2This embodiment provides a rapid-construction integral culvert, including a base component 1 disposed on the upper surface of a foundation 3 and an integral wall-top component 2 disposed on the upper surface of the base component 1. The foundation 3 is fixedly connected to the base component 1 (e.g., by integral casting of reinforced concrete structure). The foundation 3 is used to support the base component 1 and maintain the stability of the base component 1, avoiding problems such as sinking or bending of the base component 1.

[0048] Reference Figures 2-3 The base component 1 has a convex cross-section. The top of the base component 1 has a central top surface 11, and at the center of the central top surface 11 is a concave first cavity 111, which is a cuboid cavity structure. The first cavity 111 contains a first exposed horizontal rib 112, with both ends of the first exposed horizontal rib 112 fixedly connected to the base component 1. Multiple first exposed horizontal ribs 112 are arranged in a matrix to achieve multi-point connection, thereby improving structural strength. The first exposed horizontal ribs 112 are arranged laterally to connect the integrated wall and top component 2, improving the structural stability of this invention.

[0049] Reference Figure 5 The integrated wall and roof component 2 is shaped like the letter "Z". The integrated wall and roof component 2 includes a roof plate 21 and a wall panel 22 that are fixedly connected to each other; the roof plate 21 is a single, horizontally positioned component, and the wall panel 22 is a vertically positioned component. There are two wall panels 22, each positioned at one end below the roof plate 21. The top of the wall panel 22 is fixedly connected to the bottom edge of the roof plate 21 (e.g., through integral casting of reinforced concrete).

[0050] Reference Figure 5 A second cavity 220 is provided between the two wall panels 22. The second cavity 220 is a cuboid cavity structure. A second exposed horizontal rib 2201 is provided at the bottom of the second cavity 220, and both ends of the second exposed horizontal rib 2201 are fixedly connected to the two wall panels 22 respectively. Multiple second exposed horizontal ribs 2201 are provided and arranged in a matrix to achieve multi-point connection, thereby improving structural strength. The second exposed horizontal ribs 2201 are arranged laterally to connect the base component 1, improving the structural stability of this utility model.

[0051] Reference Figure 2 and Figure 6The first exposed horizontal reinforcing bar 112 and the second exposed horizontal reinforcing bar 2201 are fixedly connected by vertical tie bars 2202 and cast-in-place concrete. During construction, after the user hoists the integrated wall top component 2 and places it on the base component 1, the first exposed horizontal reinforcing bar 112 is located below the second exposed horizontal reinforcing bar 2201. Then, the user uses the vertical tie bars 2202 to connect the first exposed horizontal reinforcing bar 112 and the second exposed horizontal reinforcing bar 2201 (for example, the vertical tie bars 2202 are initially J-shaped, the user uses the bottom end of the vertical tie bars 2202 to fasten the first exposed horizontal reinforcing bar 112, and then bends the top end of the vertical tie bars 2202 to fit and fasten). The second exposed horizontal bar 2201 is then tied with wire at the intersection of the vertical tie bar 2202 and the first exposed horizontal bar 112, and at the intersection of the vertical tie bar 2202 and the second exposed horizontal bar 2201. Finally, concrete is poured so that the poured concrete fills the first cavity 111 and accumulates at the bottom of the second cavity 220 (and the concrete does not exceed the second exposed bar at the highest position). After the concrete hardens, the connection between the first exposed horizontal bar 112 and the second exposed horizontal bar 2201 is achieved.

[0052] Reference Figure 3 and Figure 5 The bottom surface of the wall panel 22 is provided with a first exposed longitudinal rib 221 and a second exposed longitudinal rib 222; the base component 1 is provided with a first grouting sleeve 113 and a second grouting sleeve 114 at the center top surface 11. The top surfaces of the first grouting sleeve 113 and the second grouting sleeve 114 are both flush with the center top surface 11, thereby ensuring that the inner cavities of the first grouting sleeve 113 and the second grouting sleeve 114 are connected to the outside, further ensuring that the first exposed longitudinal rib 221 and the second exposed longitudinal rib 222 can be smoothly inserted. The first exposed longitudinal rib 221 can be fitted into the first grouting sleeve 113, and the second exposed longitudinal rib 222 can be fitted into the second grouting sleeve 114.

[0053] Reference Figures 3-5 The first cavity 111 has a row of first grouting sleeves 113 on each side, and the second cavity 220 has a row of first exposed longitudinal ribs 221 on each side. The first exposed longitudinal ribs 221 can be respectively inserted into the first grouting sleeves 113. The first cavity 111 has a row of second grouting sleeves 114 on each side, and the second cavity 220 has a row of second exposed longitudinal ribs 222 on each side. The second exposed longitudinal ribs 222 can be respectively inserted into the second grouting sleeves 114. That is, the first cavity 111 is connected by two rows of longitudinal ribs on one side, thereby improving the connection stability.

[0054] Reference Figure 7 and Figure 8A first grouting pipe 223 is embedded within the wall panel 22, and a second grouting pipe 115, a diversion pipe 116, and a grout outlet pipe 117 are embedded within the base component 1. The top end of the first grouting pipe 223 communicates with the second cavity 220, the top end face of the first grouting pipe 223 is flush with the side wall of the second cavity 220, and the bottom end face of the first grouting pipe 223 is flush with the bottom surface of the wall panel 22. The first grouting pipe 223 is a plastic bend (e.g., polypropylene, polyethylene, or other plastic materials). The bottom end of the first grouting pipe 223 can be adapted and connected to the top end of the second grouting pipe 115; the bottom end of the second grouting pipe 115 is vertically connected to the middle of the diversion pipe 116 (for example, through heat fusion to achieve a sealed and fixed connection, or through a tee and a sealing ring to achieve a sealed and fixed connection), and the two ends of the diversion pipe 116 are respectively connected to the bottom end of the inner cavity of the first grouting sleeve 113 and the bottom end of the inner cavity of the second grouting sleeve 114; one end of the grout outlet pipe 117 is connected to the first cavity 111, and the other end is connected to the top end of the inner cavity of the first grouting sleeve 113. The grout outlet pipe 117 is arranged horizontally, and the end face of the grout outlet pipe 117 is flush with the inner wall of the first cavity 111. The user injects non-shrink grout at the top of the first grouting pipe 223. The non-shrink grout flows into the inner cavity of the first grouting sleeve 113 and the inner cavity of the second grouting sleeve 114 through the second grouting pipe 115 and the diversion pipe 116, so as to fill the gap between the first exposed longitudinal rib 221 and the first grouting sleeve 113, and the gap between the second exposed longitudinal rib 222 and the second grouting sleeve 114, thereby achieving the connection.

[0055] Reference Figure 7 and Figure 8 A gap is provided between the base component 1 and the integrated wall top component 2, and the top end of the inner cavity of the second grouting sleeve 114 communicates with the gap. The gap includes a horizontal gap and an inclined gap 2310. The horizontal gap is located between the bottom surface of the wall panel 22 and the central top surface 11. The integrated wall top component 2 also includes an extension 23, which is fixedly installed on the bottom end of the outer wall of the wall panel 22 (for example, by integral casting of reinforced concrete). The bottom of the extension 23 is provided with an inclined bottom surface 231; the top of the base component 1 is also provided with an inclined top surface 12, and the inclined gap 2310 is located between the inclined bottom surface 231 and the inclined top surface 12. The top end of the inner cavity of the second grouting sleeve 114 communicates with the inclined gap 2310. Because the non-shrink grout is injected from the bottom, the air inside the first grouting sleeve 113 is discharged through the grout outlet pipe 117 and / or the horizontal gap, and the air inside the second grouting sleeve 114 is discharged through the horizontal gap and / or the inclined gap 2310. This avoids the formation of cavities in the inner cavities of the first grouting sleeve 113 and the second grouting sleeve 114, thereby improving the grouting density and tensile strength (the tensile strength between the first exposed longitudinal rib 221 and the first grouting sleeve 113, and the tensile strength between the second exposed longitudinal rib 222 and the second grouting sleeve 114).

[0056] Reference Figure 2 , Figure 3 and Figure 5 The base component 1 also has an edge top surface 13. When the integrated wall and top component 2 is pressed onto the base component 1, the bottom surface of the wall panel 22 is adapted to be pressed onto the center top surface 11, and the inclined bottom surface 231 is adapted to be pressed onto the inclined top surface 12. The two inclined top surfaces 12 are respectively located on both sides of the first cavity 111, and the two inclined bottom surfaces 231 are respectively located on both sides of the second cavity 220. When the two inclined bottom surfaces 231 are adapted to be pressed onto the two inclined top surfaces 12 respectively, the left and right sides of the integrated wall and top component 2 are limited, that is, the first cavity 111 and the second cavity 220 are aligned, the first grouting pipe 223 and the second grouting pipe 115 are aligned, the first exposed longitudinal rib 221 is adapted to be inserted into the inner cavity of the first grouting sleeve 113, and the second exposed longitudinal rib 222 is adapted to be inserted into the inner cavity of the second grouting sleeve 114.

[0057] Reference Figure 9 The central top surface 11 has a first groove 118, and the inclined top surface 12 has a second groove 121. One end of the first groove 118 is vertically connected to the top of the inner cavity of the second grouting sleeve 114, and the other end is connected to the end of the second groove 121; the end of the second groove 121 away from the first groove 118 is connected to the outside. Near the edge top surface 13, the width of the second groove 121 gradually decreases (ranging from 3 mm to 15 mm), allowing air flowing out from the top of the inner cavity of the second grouting sleeve 114 to flow smoothly through the first groove 118 and the second groove 121. Meanwhile, the non-shrink grout flowing out from the top of the inner cavity of the second grouting sleeve 114 is difficult to flow out through the second groove 121, thus stopping the flow of the non-shrink grout and promoting its hardening, reducing the waste of building materials.

[0058] The first groove 118, the second groove 121, and the third groove are arranged along the same line. The cross-sections of the first groove 118, the second groove 121, and the third groove are all semi-circular, which facilitates mold manufacturing.

[0059] Reference Figure 8 The first grouting sleeve 113 and the second grouting sleeve 114 are disposed on the side of the first cavity 111, and the second grouting pipe 115 and the diversion pipe 116 are disposed between the first grouting sleeve 113 and the second grouting sleeve 114.

[0060] Reference Figures 7-9A first grouting sleeve 113 is disposed inside the second grouting sleeve 114 to facilitate the installation of the grout outlet pipe 117. A grout discharge pipe 1132 is connected to the top of the side wall of the first grouting sleeve 113 near the first cavity 111. The grout discharge pipe 1132 is integrally fixedly connected to the side wall of the first grouting sleeve 113 (e.g., by casting or forging). The grout discharge pipe 1132 is inserted into the end of the grout outlet pipe 117 and is sealed and fixedly connected by elasticity and friction. A grouting pipe 1131 is provided at the bottom of the side wall of the first grouting sleeve 113 near the second grouting sleeve 114. This grouting pipe 1131 is integrally fixedly connected to the first grouting sleeve 113 (e.g., by casting or forging). A grouting pipe 1131 is also provided at the bottom of the side wall of the second grouting sleeve 114 near the first grouting sleeve 113. This grouting pipe 1131 is integrally fixedly connected to the second grouting sleeve 114 (e.g., by casting or forging). Two grouting pipes 1131 are respectively inserted into the two ends of the diversion pipe 116, and the grouting pipes 1131 and the diversion pipe 116 are sealed and fixedly connected by elasticity and friction.

[0061] Reference Figure 8 The top end of the inner cavity of the first grouting sleeve 113 is connected to the grout discharge pipe 1132, and the grout discharge pipe 1132 is connected to the grout outlet pipe 117, thereby realizing the transportation of non-shrink grout; the bottom side wall of the inner cavity of the first grouting sleeve 113 is connected to the corresponding grouting pipe 1131, the bottom side wall of the inner cavity of the second grouting sleeve 114 is connected to the corresponding grouting pipe 1131, and the grouting pipe 1131 is connected to the diversion pipe 116, thereby realizing the transportation of non-shrink grout.

[0062] The first exposed longitudinal reinforcement 221 is disposed inside the second exposed longitudinal reinforcement 222 to adapt to the relative positions of the first grouting sleeve 113 and the second grouting sleeve 114.

[0063] Reference Figure 10 The base component 1 has a pre-embedded guide post 119 (e.g., fixed by embedding) at the inclined top surface 12, and a pre-embedded guide sleeve 232 at the bottom of the extension 23. The pre-embedded guide post 119 can be fitted into the pre-embedded guide sleeve 232 (e.g., fixed by embedding). The top of the pre-embedded guide post 119 is conical, so the pre-embedded guide sleeve 232 is more easily fitted onto the outer circumference of the pre-embedded guide post 119 when it is lowered, so as to realize the guiding function. When the integrated wall and top component 2 is lowered, the pre-embedded guide post 119 and the pre-embedded guide sleeve 232 realize the guiding function, prevent the lateral relative movement between the integrated wall and top component 2 and the base component 1, so as to avoid the problem of the first exposed longitudinal rib 221 and the second exposed longitudinal rib 222 being bent.

[0064] Reference Figure 12 The base component 1 is a reinforced concrete structure, and a first steel mesh 101 is provided inside the base component 1. The first steel mesh 101 is fixedly connected to the first grouting sleeve 113 and the second grouting sleeve 114 respectively (in combination). Figure 8 (For example, through threaded connection). The two ends of the first exposed transverse rib 112 are respectively fixedly connected to the first reinforcing mesh 101, that is, both ends of the first exposed transverse rib 112 are part of the first reinforcing mesh 101. Some of the reinforcing bars in the first reinforcing mesh 101 are inserted laterally into the insertion holes on the outer wall of the first grouting sleeve 113, and some of the reinforcing bars in the first reinforcing mesh 101 are inserted laterally into the insertion holes on the outer wall of the second grouting sleeve 114, thereby improving the tensile strength.

[0065] Reference Figure 13 The integrated wall-top component 2 is a reinforced concrete structure. A second steel mesh 201 is provided within the integrated wall-top component 2. The second steel mesh 201 is fixedly connected to the first exposed longitudinal reinforcement 221 and the second exposed longitudinal reinforcement 222 (for example, through an integrated fixed connection; that is, several longitudinal reinforcements within the second steel mesh 201 extend downwards to form the first exposed longitudinal reinforcement 221 and the second exposed longitudinal reinforcement 222). Both ends of the second exposed transverse reinforcement 2201 are fixedly connected to the second steel mesh 201, meaning both ends of the second exposed transverse reinforcement 2201 are part of the second steel mesh 201.

A stud is provided at the bottom of the lifting ring 212 (e.g., by an integrated fixing connection). The stud can be inserted into the lifting sleeve 211 and connected by threads. The operator connects the crane's sling 5 to the lifting ring 212, enabling the overall lifting of the wall-top integrated component 2. The lifting sleeve 211 is fixedly connected to the second reinforcing mesh 201 (part of the reinforcing bars of the second reinforcing mesh 201 are horizontally inserted into the insertion holes on the outer wall of the lifting sleeve 211, and part of the reinforcing bars of the second reinforcing mesh 201 are welded to the outer wall of the lifting sleeve 211. The lifting sleeve 211 and the wall-top integrated component 2 are connected by multi-point anchor plates).

[0069] Reference Figure 11 It also includes a side bracing assembly 6 installed inside the trough 4 and capable of abutting against the outer wall of the integrated wall top component 2. The side bracing assembly 6 includes an abutting rod 61, an abutting plate 62, and an abutting block 63; one end of the abutting rod 61 is hinged to the abutting plate 62, and the other end is fixedly connected to the abutting block 63 (for example, by casting). The abutting block 63 is a reinforced concrete block and is embedded in the soil layer outside the trough 4 to apply a supporting force to the abutting rod 61 and prevent the soil layer at the lower end of the abutting rod 61 from sinking due to force concentration.

[0070] Usage steps: ① Hoist the integrated wall and top component 2 above the base component 1 (refer to...) Figure 2 Then it is lowered so that the integrated wall and top component 2 is pressed onto the base component 1. During the process, the pre-embedded guide post 119 is inserted into the pre-embedded guide sleeve 232 (refer to...). Figure 10 The first exposed longitudinal reinforcement 221 is inserted into the first grouting sleeve 113, and the second exposed longitudinal reinforcement 222 is inserted into the second grouting sleeve 114 (refer to...). Figure 9 ); ② Install the side support assembly 6 in the grouting tank 4, and use the side support assembly 6 to limit the integrated wall top component 2; ③ Inject non-shrink grout into the top of the first grouting pipe 223, so that the non-shrink grout fills the inner cavity of the first grouting sleeve 113 and the inner cavity of the second grouting sleeve 114 (when the user observes water seepage at the end of the second groove 121, it is judged that the inner cavity of the second grouting sleeve 114 is filled with non-shrink grout; when the user observes non-shrink grout flowing out of the grout outlet pipe 117, it is judged that the inner cavity of the first grouting sleeve 113 is filled with non-shrink grout), excess ④ The non-shrink slurry overflows from the slurry outlet pipe 117 into the first cavity 111; ⑤ Let it stand until the non-shrink slurry hardens; ⑥ Use vertical reinforcing bars 2202 to connect the first exposed horizontal bars 112 and the second exposed horizontal bars 2201 to form a steel mesh structure; ⑦ Pour concrete into the first cavity 111 and the second cavity 220 until the liquid level of the concrete slurry exceeds the second exposed horizontal bar 2201 at the highest position and reaches the preset thickness of the concrete; ⑧ Harden the concrete; ⑨ Remove the side support assembly 6 and backfill the excavated soil into the trench 4.

[0071] In this invention, non-shrink grout is injected into the inner cavity of the second grouting sleeve 114 located on the outer side using the first grouting pipe 223, the second grouting pipe 115, and the diversion pipe 116. The air in the inner cavity of the second grouting sleeve 114 is discharged through the inclined gap 2310. Therefore, the side of the second grouting sleeve 114 near the outer wall of the wall panel 22 does not need to be equipped with a grouting pipe 1131 and a grout outlet pipe 117. Thus, the end face of the grouting pipe 1131 and the end face of the grout outlet pipe 117 will not be exposed from the outer wall of the wall panel 22, which can avoid the problem of reduced waterproof performance of the wall panel 22.

[0072] Thus, the non-shrink grout overflowing from the second grouting sleeve 114 is blocked by the second groove 121, which gradually decreases in width, and cannot flow out to the outside through the inclined gap 2310, thereby avoiding material waste (when the second groove 121 is blocked by the non-shrink grout, the pressure inside the second grouting sleeve 114 increases, and the non-shrink grout injected through the first grouting pipe 223, the second grouting pipe 115 and the diversion pipe 116 will flow into the second grouting sleeve 114 and the first cavity 111; when the user plugs the outlet pipe 117 with a wooden plug, the non-shrink grout will flow into the second grouting sleeve 114 first, thereby avoiding the problem that the first grouting sleeve 113 is filled before the second grouting sleeve 114; after the second grouting sleeve 114 is filled, the user pulls out the wooden plug, and the non-shrink grout flows into the first grouting sleeve 113 and fills it).
