Description

Technical Field

[0001] The present invention relates to the technical field of basement construction, and more specifically, to a leakage plugging construction method for the deformation joint of a basement connection opening. Background Art

[0002] With the development of high-rise buildings, the scale of basements such as underground civil air defense and garages is getting larger and larger. Due to changes in engineering hydrogeology, structural stiffness, and temperature deformation, during structural design, the principle of "release" is generally adopted, and post-cast strips or deformation joints are set. There are specific practices for the waterproof structure of deformation joints in design and standard drawings. However, in actual construction, due to factors such as the buried depth of the basement, soil layer properties, hydrodynamic pressure, and construction quality, leakage of the deformation joints of the connection opening caused by structural deformation changes and uneven settlement occurs frequently, and it is very difficult to plug the leakage. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a leakage plugging construction method for the deformation joint of a basement connection opening, which can save the leakage plugging operation time, reduce the number of leakage plugging operators, and is easy to construct and convenient for maintenance and repair.

[0004] The present invention adopts the following technical solutions:

[0005] A leakage plugging construction method for the deformation joint of a basement connection opening, comprising the following steps:

[0006] Embed a middle embedded rubber waterstop and embed a drain pipe;

[0007] Formwork;

[0008] Pour concrete;

[0009] Clean the deformation joint;

[0010] Drill holes and drive expansion bolts;

[0011] Embed a rubber expansion waterstop strip into the deformation joint;

[0012] Use sealant to seal the deformation joint;

[0013] Install a removable waterstop;

[0014] Close the steel plate.

[0015] Further, before the concrete construction of the deformation joint of the connection opening, embed a drain pipe in the deformation joint of the floor slab. Embed it before pouring the floor slab. The drain pipe leads to the nearest sump from the position of the deformation joint to introduce the water flow into the sump.

[0016] Further, the drain pipe is a PVC pipe.

[0017] Further, after pouring the concrete, after the construction of the deformation joint is completed and the concrete strength of the shear walls on both sides of the deformation joint reaches the design grade, remove the formwork and clean the deformation joint to make the two sides of the deformation joint horizontal and vertical.

[0018] Further, the spacing of the holes drilled for the expansion bolts is 15 cm.

[0019] Further, the width of the rubber expansion water stop strip is 3 cm.

[0020] Further, the steel plate is installed on the expansion bolts and the steel plate covers the rubber expansion water stop strip.

[0021] Beneficial effects

[0022] The present invention can save the plugging operation time and reduce the number of plugging operation personnel. Moreover, the construction is easy and the maintenance and repair are convenient. If leakage occurs during the completion stage or during long-term use, the open drainage waterproof effect is remarkable. Description of the drawings

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Formwork;

[0038] In an embodiment of the present invention, before the concrete construction of the deformation joint 2 of the communication port, a drain pipe 1 is embedded in the deformation joint of the floor slab, which is embedded before the floor slab is poured. The drain pipe 1 leads to the nearest sump from the position of the deformation joint, and the water flow is introduced into the sump. After the residence is delivered for use, the water at the communication port can flow into the sump through the embedded drain pipe, achieving the effect of water stop and waterproofing.

[0040] In an embodiment of the present invention, after the concrete is poured, after the construction of the deformation joint 2 is completed and the concrete strength of the shear walls on both sides of the deformation joint 2 reaches the design grade, the formwork is removed and the deformation joint is cleaned to make the two sides of the deformation joint horizontal and vertical. Cleaning the deformation joint 2 is for facilitating the next construction step.

[0041] In an embodiment of the present invention, the spacing of the holes drilled for installing the expansion bolts 3 is 15 cm.

[0042] In an embodiment of the present invention, the width of the rubber expansion water stop strip 4 is 3 cm. For different construction positions, the width of the rubber expansion water stop strip 4 can be adjusted as needed.

[0043] In an embodiment of the present invention, the steel plate 7 is installed on the expansion bolts 3, and the steel plate 7 covers the rubber expansion water stop strip. The steel plate 7 plays a sealing role. The expansion bolts 3 are used to install the steel plate 7.

[0044] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
