Abstract

The present invention discloses a device for pouring water collection pit pipes to prevent displacement, comprising a sewage pipe, a fixed plate, and a wooden box. The sewage pipe is fixedly connected to a pre-buried steel mesh via fixed ribs. The water outlet of the sewage pipe is fixedly connected to the fixed plate and passes through the surface of the fixed plate. The wooden box is provided with a slot extending through in a vertical direction. The position of the slot is adapted to the position of the sewage pipe, and the sewage pipe is located within the slot. The fixed plate is located inside the wooden box and vertically slides with the inner wall of the slot. The device for pouring water collection pit pipes to prevent displacement disclosed by the present invention can be assembled on-site according to the construction conditions on site, and will not be affected by the upward movement of the wooden box template during pouring. This ensures the construction quality of the sump and the normal connection between the sump and the sewage pipe, and the wooden box, chute, and fixed plate can be reused through demoulding at a later stage.

Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a sump pipe anti-displacement pouring device. Background Art

[0002] A sump is a drainage method that needs to be set up when the groundwater level is relatively high and the base elevation is below the groundwater level during the excavation of the foundation pit of a construction project. Sump drainage is also called the open drainage method. During the excavation of the foundation pit, a sump is set up at the bottom of the pit, and drainage ditches are dug around the bottom or in the center of the pit to allow water to flow into the sump, and then it is pumped away with a sewage pump (submersible sewage pump). The pumped water should be directed to a place away from the foundation pit to prevent it from flowing back into the foundation pit. During construction in the rainy season, intercepting ditches should be excavated or earthen embankments should be built around the foundation pit or upstream of the surface water to prevent surface water from flowing into the foundation pit. This method is suitable for coarse-grained soil layers, and can also be used for clay layers with low water seepage.

[0003] Nowadays, all types of basement floors are equipped with sump pits. During construction, the sump formwork often shifts upward, causing pipes to be squeezed and deformed. This makes it difficult to collect all the sewage into the sump, and thus, the sewage discharge function cannot be achieved. This device is now developed to prevent pipe deformation caused by the displacement of the wooden box.

[0004] Therefore, in order to solve the above problems, a water collection pit pipe anti-displacement pouring device is needed, which can be assembled on-site according to the on-site construction conditions and will not be affected by the upward movement of the wooden box template during pouring, thereby ensuring the construction quality of the water collection pit and the normal connection between the water collection pit and the sewage pipe. In addition, the wooden box, chute and fixed plate can be reused through later demoulding. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide a water collection pit pipe anti-displacement casting device that can be assembled on-site according to the on-site construction conditions and will not be affected by the upward movement of the wooden box template during casting, thereby ensuring the construction quality of the water collection pit and the normal connection between the water collection pit and the sewage pipe, and the wooden box, chute and fixed plate can be reused through later demoulding.

[0006] The anti-displacement pouring device for a sump pipe of the present invention comprises a sewage pipe, a fixed plate and a wooden box. The sewage pipe is fixedly connected to a pre-buried steel mesh via fixed ribs. The water outlet end of the sewage pipe is fixedly connected to the fixed plate and passes through the plate surface of the fixed plate. A slot extending through the wooden box in a vertical direction is provided. The position of the slot is adapted to the position of the sewage pipe, and the sewage pipe is located in the slot. The fixed plate is located inside the wooden box and vertically slides with the inner side wall of the slot.

[0007] Furthermore, the width of the fixing plate is greater than the width of the slot, and the fixing plate is fitted to the inner side wall of the slot.

[0008] Furthermore, a sliding groove is provided on the inner side wall of the slot to limit the sliding movement of the fixing plate within the sliding groove.

[0009] Furthermore, the sliding groove is a U-shaped groove, which is symmetrically arranged on the inner side walls on both sides of the slot.

[0010] Furthermore, the water outlet end of the sewage pipe is connected to the fixed plate through a fixedly connected wing ring.

[0011] Furthermore, fixing bars for fixing the sewage pipe are provided on both the inner and outer sides of the embedded steel mesh.

[0012] Before concrete is poured, the wooden box is covered with pre-embedded steel mesh. The anchoring bars are welded to the pre-embedded steel mesh to secure the sewage pipe. The wing ring is welded to the sewage pipe. A slot is cut into one side of the wooden box plank, slightly larger than the diameter of the sewage pipe. The anchor plate and wing ring are bolted together, while the chute is removably bolted to the wooden box. The openings of the two chutes are positioned opposite each other, with the clear distance between them exceeding the slot width. The distance between the bottoms of the U-shaped openings of the two chutes is slightly larger than the width of the anchor plate.

[0013] During concrete pouring, any upward movement of the crate will cause it to move upward along the chute (relative motion: with the crate as a reference, the sewage pipe and wing ring will move downward along the chute, driven by the fixed plate). The position of the sewage pipe remains unchanged. After the concrete pour is complete, the crate is disassembled into planks, the bolts are removed, and the crate, chute, and fixed plate can be disassembled and recycled.

[0014] The beneficial effects of the present invention are as follows: the anti-displacement pouring device for a sump pipe disclosed in the present invention can be assembled on-site according to the on-site construction conditions, and will not be affected by the upward movement of the wooden box template during pouring, thereby ensuring the construction quality of the sump and the normal connection between the sump and the sewage pipe, and the wooden box, chute and fixed plate can be reused through later demoulding.
