A concrete solid drainage device, mold and construction method

Abstract

The invention discloses a concrete solid drainage device, a mold and a construction method. The concrete solid drainage device includes a device main body made of high-porosity concrete, the top of the device main body is a semicircular arc surface, and the semicircular The axis of the arc surface extends along the front-to-back direction, and the left and right sides of the semi-arc surface are in contact with the rectangular plane at the bottom of the main body of the device, and the front side of the rectangular plane exceeds the front of the semi-arc surface. and the front side of the rectangular plane is connected to the front side of the semi-arc surface through a transitional arc surface, and the rear side of the rectangular plane is connected to the semi-arc surface through a semi-circular plane connected at the rear. The beneficial effects of the present invention: it is made of concrete with high porosity and high water permeability, and has a special structure to ensure that there will be no pipe plugging, improve drainage efficiency, and ensure that the soil will not be lost. It ensures the stability of the slope and 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.
