Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a drainage structure for pouring a post-casting belt. Background Art

[0002] Post-cast strips are a construction technology in construction projects, mainly used to control concrete shrinkage and temperature stress and prevent cracks in concrete structures. Post-cast strips are usually set in certain parts of the structure, such as beams, slabs, columns, walls, etc., to separate and control concrete shrinkage. Reasonable setting of post-cast strips can improve the stability and durability of the structure. The construction method of post-cast strips has been widely used in construction projects.

[0003] However, the sealing time of the post-casting strip is generally long, and there is no structural slab before sealing, only the cushion layer to isolate the foundation. The cushion layer is generally ordinary concrete, without anti-seepage design requirements, which is easy to cause water seepage and water accumulation before the post-casting strip is closed, and may even cause gushing in the rainy season. In this case, if drainage treatment is not carried out, too much water will accumulate during the construction of the post-casting strip, resulting in poor molding quality of the post-casting strip and a high risk of leakage in the later period; especially when constructing in a foundation with rich water content, before the bottom plate post-casting strip is closed, there is only a cushion layer in the post-casting strip area to isolate the foundation and the room. If the cushion layer construction quality is poor, or it is not closed for a long time, water will penetrate the cushion layer, causing water accumulation in the post-casting strip, seriously affecting the subsequent post-casting strip construction quality. Utility Model Content

[0027] See also Figure 1-2 The utility model is a drainage structure for pouring post-casting strips, comprising: a diversion pipe 1, a diversion valve 2 and a grouting valve 3. The length of the diversion pipe 1 corresponds to the thickness of the cushion layer, and the length of the diversion pipe 1 can be slightly larger than the thickness of the cushion layer. When in use, the top of the diversion pipe 1 is roughly flush with the top surface of the cushion layer; the bottom of the diversion pipe 1 should be at the foundation position. The diversion pipe 1 can be a galvanized steel pipe. The diversion valve 2 is arranged at the top of the diversion pipe 1; it is opened during the drainage process, and can be closed to prevent water from continuing to gush out after the drainage is completed and the docking water pipe is removed. The grouting valve 3 is arranged on the upper side of the diversion pipe 1, and the height of the grouting valve 3 is lower than the height of the diversion valve 2. The grouting valve 3 is a one-way valve. When the grouting one-way valve is used to divert the tin-plated steel pipe for drainage, water cannot gush out from this valve. After the valve is closed after the drainage is completed, the plugging king is injected into the diversion galvanized steel pipe through the grouting one-way valve. Furthermore, a connection portion 5 is provided on the outer side of the grouting valve 3, and the connection portion 5 and the side wall of the flow guide pipe 1 are enclosed to form a grouting space, so that the grouting operation can be facilitated.

The fixing portion 4 may be a galvanized steel plate. The fixing portion 4 may be welded and fixed to the guide tube 1 to form a whole. Furthermore, when in use, a rubber ring 6 may be arranged between the fixing portion 4 and the cushion layer to improve the sealing and waterproof performance.

[0029] The working principle of this utility model:

[0030] When the device is used, the installation point of the guide pipe 1 is first arranged according to the leakage situation of the cushion layer, and the cushion layer is chiseled after selection, and the chiseling process needs to be chiseled to the base layer; after the chiseling is completed, the guide pipe 1 is fixed in the hole chiseled in the cushion layer, and then the water pipe is connected to the upper end of the guide pipe 1, and the drainage valve 2 is opened to drain the water in the foundation to the drainage system for discharge, so as to ensure the dryness of the overall environment; the post-casting strip outside the drainage structure position is poured, and after the pouring is completed, the water pipe is taken out, the drainage valve 2 is closed, and then the leak-proof king is injected into the guide pipe 1 through the grouting valve 3 until the guide pipe 1 is filled; after the grouting is completed, there is no need to dismantle the device, and the waterproof mortar is directly used to smooth it, and the anti-water membrane is laid for waterproof reinforcement treatment; concrete is poured at the location of the drainage structure until it is flush with the post-casting strips at other locations.
