Concrete solid water discharge device, mold and construction method

Abstract

The invention discloses a concrete solid water discharge device, a mold and a construction method. The concrete solid water discharge device comprises a device body made of concrete with high porosity; and a semi-circular-arc surface is arranged at the top of the device body, the axis of the semi-circular-arc surface extends in the front-rear direction, the left side and the right side of the semi-circular-arc surface are connected with a rectangular plane located at the bottom of the device body, the front side of the rectangular plane extends beyond the front surface of the semi-circular-arcsurface and then extends forwardly, the front side of the rectangular plane is connected with the front side of the semi-circular-arc surface through a transitional arc surface, and the rear side ofthe rectangular plane is connected with the rear side of the semi-circular-arc surface through a semi-circular plane. The concrete solid water discharge device has the beneficial effects that the concrete solid water discharge device is made of the concrete with high porosity and high water permeability, and is of a special structure to ensure that the pipe blocking phenomenon does not occur, thewater discharge efficiency is improved, it is ensured that a soil body is not lost, the stability of a slope is ensured, and the concrete solid water discharge device is economical and practical.

Description

technical field [0001] The invention relates to the technical field of drain pipes, in particular to a concrete solid drain device, a mold and a construction method. Background technique [0002] At present, the domestic deep foundation pit excavation slope protection basically adopts spray anchor technology, and the installation of drain pipes is an essential process, but the drain pipes made of ordinary PVC pipes are not easy to install, and they are easy to block the pipes and cause slope instability. [0003] Aiming at the current technology using PVC pipes as foundation pit drainage pipes, and after the excavation of the foundation pit is completed, when the next step of construction is carried out, the PVC pipes are blocked and cause slope instability. At present, no effective solution has been proposed. Contents of the invention [0004] Aiming at the above technical problems in the related art, the present invention proposes a concrete solid drainage device, which ...

Problems solved by technology

[0002] At present, the domestic deep foundation pit excavation slope protection basically adopts spray anchor technology, and the installation of the drain pipe is an essential process, but the drain pipe made of ordinary PVC pipe is not easy to install, and it is easy to block the pipe and cause the slope to be unstable.

[0003] In view of the current technology that uses PVC pipes as foundation pit drainage pipes, and after the excavation of the foundation pit is completed, when the next step of construction is carried out, the problem of slope instability caused by PVC pipe plugging has not yet been proposed.
