Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a node structure of a drainage ditch adjacent to a foundation pit. Background Art

[0002] During construction, it is often necessary to set up drainage ditches around the foundation pit to drain water and prevent the water from being drained in time when there is heavy rain.

[0003] After searching, a Chinese patent with publication number CN213867890U discloses a foundation pit drainage ditch, including a number of prefabricated support units installed in the drainage ditch and connected to each other, the prefabricated support units including a mounting plate abutting against the bottom wall of the foundation pit, a protective plate hingedly arranged on opposite sides of the mounting plate, and a fixed plate hingedly arranged on a side of the protective plate away from the mounting plate; the two protective plates are respectively abutted against two opposite inner walls of the drainage ditch, the fixed plate is abutted against the ground, and the fixed plate is provided with anchor bolts fixing the fixed plate to the ground; a telescopic support assembly for squeezing the protective plate against the inner wall of the drainage ditch is provided between the two protective plates, and the two ends of the telescopic support assembly are respectively abutted against the opposite side walls of the protective plate.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] The existing drainage ditch around the foundation pit is built with concrete or cement bricks. However, when the ground settles, leakage often occurs, which easily affects the use of the drainage ditch. At the same time, fire water pipes and cables need to be set up separately, resulting in low construction efficiency, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a node structure near the foundation pit drainage ditch. The construction method can not only avoid water leakage caused by ground subsidence, but also can set cables and fire water pipes, saving construction time and improving efficiency.

[0007] The technical solution to achieve the purpose of the utility model is: a node structure of a drainage ditch adjacent to a foundation pit, comprising a groove, a concrete cushion layer is fixedly cast at the bottom of the groove, a pair of cement bricks 1 are fixedly installed on the surface of the concrete cushion layer and both sides of the groove, a waterproof membrane is laid between the cement brick 1 and the concrete cushion layer, a waterproof protective layer is provided at the inner bottom of the waterproof membrane, and a pair of cement bricks 2 are fixedly installed between the waterproof protective layer and the waterproof membrane.

[0008] In some embodiments, a plurality of steel bar supports are fixedly installed between a pair of cement bricks, and grooves matching the steel bar supports are opened near the top of the cement bricks, and drainage covers are fixedly installed on the surfaces of the steel bar supports.

[0009] In some embodiments, a support plate and a pair of placement plates are fixedly mounted on the inner bottom and middle of each of the steel bar supports.

[0010] In some embodiments, a pair of fire-fighting water pipes are fixedly installed between each of the support plates, and a protective tube is fixedly installed on each of the placement plates, and a cable is arranged inside the protective tube.

[0011] In some embodiments, V-shaped reinforcing ribs are fixedly installed between the cement brick 2 and the steel bar support.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First: The utility model sets two layers of cement bricks as the main body of the drainage ditch, and sets a waterproof membrane inside to effectively prevent leakage when the ground sinks, thereby improving the drainage stability of the drainage ditch. In addition, a plurality of steel bar supports are installed on the inner cement bricks. The steel bar supports can not only support the cement bricks to a certain extent, but also provide convenience for the installation of cables and fire water pipes. At the same time, a waterproof pipe is arranged outside the cable to protect the cable. A support plate is also arranged at the bottom of the steel bar support, which can stably fix the fire water pipe on the steel bar support.

[0014] Secondly, the utility model further improves the strength of the steel bar bracket and the cement brick by fixing and installing V-shaped reinforcing ribs between the cement brick and the steel bar bracket, making the structure of the drainage ditch more stable.

[0015] The existing drainage ditch around the foundation pit is solved by building a drainage ditch with concrete or cement bricks. However, when the ground settles, leakage often occurs, which easily affects the use of the drainage ditch. At the same time, fire water pipes and cables need to be set up separately, resulting in low construction efficiency, so there are certain limitations. BRIEF DESCRIPTION OF THE DRAWINGS
