Description

Technical Field

[0001] The present application relates to the technical field of pipe gallery construction, and in particular to a waterproof construction method for deformation joints of a comprehensive pipe gallery structure. Background Art

[0002] At present, underground structures such as integrated pipeline corridors play an important role in urban construction, especially in their ability to effectively integrate various municipal pipelines and improve the operating efficiency and safety of urban infrastructure. In order to ensure the long-term stable operation of these facilities, waterproofing has become one of the key links, especially for the underground part of the integrated pipeline corridor. Due to its complex use environment and high waterproofing requirements, how to effectively solve the waterproofing problem of expansion joints is particularly important.

[0003] At present, there are two common methods for waterproofing the expansion joints of integrated pipe corridors: one is to fix the rubber waterstop by penetrating it on the formwork or structural steel bars; the other is to clamp and fix the rubber waterstop with end forms or wooden squares. Although the former method is more firmly fixed, it will leave penetration holes on the rubber waterstop, destroying its integrity and affecting the water-stopping effect; although the latter method will not damage the waterstop, it is easy to move due to vibration during the concrete pouring process due to insufficient fixation, causing the waterstop to deviate from the predetermined position, thereby affecting the waterproof performance.

[0004] Both of the above methods have certain defects, especially in terms of fixing effect and waterproof performance. Specifically, the method of penetrating the rubber waterstop will significantly reduce the overall waterproof ability of the waterstop, while the clamping method cannot ensure the stability of the waterstop during the pouring process, which easily leads to the position deviation of the waterstop, thus affecting the waterproof effect and appearance quality of the structure. Therefore, a new method is urgently needed to solve these problems in order to improve the waterproof reliability and construction quality of the deformation joints of the integrated pipe gallery. Summary of the invention

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the present application provides a method for waterproofing the deformation joints of a comprehensive pipe gallery structure, which can effectively solve the leakage problem in the waterproofing construction of the deformation joints of the comprehensive pipe gallery structure, improve the construction quality and efficiency, and at the same time ensure the safety and stability of the structure.

[0006] This application is implemented through the following technical solutions: A waterproof construction method for deformation joints of a comprehensive pipe gallery structure comprises the following steps: Step 1: According to the thickness of the poured concrete and the width of the embedded water stop, a tooling template is manufactured, wherein the tooling template includes a panel and a rib plate, wherein the front side of the panel abuts against the poured concrete, and the rib plates are symmetrically arranged at right angles on both sides of the back side of the panel, and main ribs are provided at the two inner corners formed by the rib plates and the panel, and the two main ribs are supported by longitudinal ribs arranged at intervals; Step 2: evenly opening tension holes on the panel according to the width of the poured concrete, and the number of the tension holes is not less than three; Step three, tying the waterstop steel bars to form a waterstop steel bar skeleton; Step 4: Welding a first pair of tension screws and a second pair of tension screws which are arranged transversely on the side of the steel bar skeleton, wherein the first pair of tension screws are located below the second pair of tension screws, the ends of the first pair of tension screws and the second pair of tension screws both extend out of the steel bar skeleton, and positioning pieces are provided on the first pair of tension screws and the second pair of tension screws; Step 5: insert a tooling template onto the first tensioning screw through the tensioning hole to form a lower mold body, wherein the front side of the lower mold body abuts against the positioning piece, and the back side is fixed by a locking nut threadedly connected to the tensioning screw; Step 6: overlap the embedded water stop on the lower mold body, wherein the overlap width of the embedded water stop and the lower mold body is w, w=a / 2+b, a is the width of the embedded water stop, and b is the width of the deformation joint; Step 7, insert another tooling template into the second tensioning screw through the tensioning hole to form an upper mold body, wherein the front side of the upper mold body abuts against the positioning piece, and the back side is fixed by a locking piece threadedly connected to the tensioning screw; Step eight, check the installation position of the upper mold, the embedded waterstop and the lower mold. After ensuring that they are correct, set up the outer mold outside the steel frame and pour concrete.

[0008] Optionally, the height of the tooling template is half the thickness of the poured concrete, and the width is not less than the sum of the widths of the embedded waterstop and the deformation joint.

[0009] By adopting the above technical solution, the height of the tooling template is set to half the thickness of the poured concrete, which further enables the template to be designed modularly, reducing the production cost and cycle of the template, and can better adapt to the needs of pouring concrete of different thicknesses, ensuring the stability and reliability of the template. At the same time, the design of the template width is not less than the sum of the width of the embedded waterstop and the deformation joint, ensuring the area of ​​the waterstop clamped, and ensuring that the waterstop can be accurately centered in the deformation joint, effectively preventing the position of the waterstop from shifting, and improving the waterproof performance.

[0010] Optionally, in step seven, before the upper mold body and the second tension screw are fixed, a clamping mechanism is first fixed between the upper mold body and the lower mold body; the clamping mechanism is used to limit the position between the upper mold body and the lower mold body, and to form a clamp for the central embedded waterstop.

[0011] By adopting the above technical scheme, the clamping mechanism can effectively limit the positional relationship between the upper mold body and the lower mold body, so that the embedded waterstop can remain stable during the pouring process, and further avoid the positional displacement between the upper mold body and the lower mold body due to vibration, thereby ensuring that the waterstop is centered and improving the waterproof performance and pouring quality.

[0012] Further optionally, the clamping mechanism includes a clamping body and an adjusting bolt; the clamping body is an L-shaped structure, including a transverse portion and a longitudinal portion, the transverse portion is provided with a first waist circular hole, and the longitudinal portion is provided with a second waist circular hole; wherein the two clamping bodies are arranged in a C shape, and the middle portion is fixed by an adjusting bolt passing through the second waist circular hole.

[0013] By adopting the above technical solution, the design of the clamping mechanism allows the distance between the upper mold body and the lower mold body to be accurately adjusted, ensuring that the embedded waterstop is always in the center of the deformation joint during the pouring process, effectively avoiding the waterstop offset problem caused by the traditional fixing method, and improving the waterproof effect and the integrity of the structure; specifically, the combination of the L-shaped clamp and the adjusting bolt not only enhances the stability of the fixation, but also facilitates quick loading and unloading, improves construction efficiency, and has a simple structure and low production cost. The design of the second waist round hole can also be adjusted in length according to actual conditions.

[0014] Optionally, a tooling hole is provided on the rib plate.

[0015] By adopting the above technical solution, tooling holes are provided on the rib plate, so that the tooling formwork can be more flexibly adapted to different construction needs, and it is convenient to adjust and fix the position of the formwork, which improves the construction efficiency and accuracy, and the formwork can be expanded according to the actual concrete pouring structure needs. Specifically, the presence of tooling holes can facilitate the installation of auxiliary formwork or other auxiliary tools, such as clamping mechanisms, further enhancing the stability and reliability of the formwork system, ensuring that the embedded waterstop always maintains the correct fixed position during the pouring process, effectively avoiding the position offset problem caused by the traditional fixing method, and improving the waterproof effect.

[0016] Optionally, a sub-mold body is provided on the tooling template, and the sub-mold body is fixed on the tooling template through a tooling hole.

[0017] By adopting the above technical solution, the setting of the auxiliary mold body allows the tooling template to be flexibly adjusted according to actual construction needs, improving the adaptability and versatility of the template. Specifically, the auxiliary mold body can be fixed at different positions through the tooling holes, thereby changing the effective size of the template, better matching waterstops and deformation joints of different specifications, ensuring the position accuracy and fixing reliability of the waterstop, and thus improving the waterproof effect.

[0018] Optionally, the positioning member is in a conical platform structure with a threaded hole in the middle, which is threadedly connected to the tension screw, and the large end surface of the positioning member is located outside the steel frame.

[0019] By adopting the above technical scheme, the conical platform structure of the positioning piece can effectively prevent the tooling formwork from being displaced during the pouring process, ensure the position accuracy and stability of the embedded waterstop, and thus improve the waterproof effect; the threaded connection design of the positioning piece makes installation and disassembly easier, thereby improving construction efficiency; among them, the large end surface is located on the outside of the steel skeleton to provide better support, further enhance the fixing effect of the waterstop, and also facilitate later removal.

[0037] Step eight, check the installation position of the upper mold body, the embedded water stop 8 and the lower mold body, and after ensuring that they are correct, set up the outer mold outside the steel frame 2 and pour concrete; specifically, after the installation is completed, the installation position of each component should be carefully checked to ensure that it is correct before pouring; during the pouring process, attention should be paid to uniform vibration to avoid damage to the embedded water stop 8; the concrete structure after pouring is referenced Figure 4 .
