River sewage interception device and construction method thereof

Abstract

The invention relates to a river sewage interception device and a construction method thereof. The river sewage interception device comprises an impervious soft enclosure capable of bending and deforming, and a pair of pervious filtering fences, wherein the soft enclosure is erected in a river and arranged opposite to a river bank, the bottom of the soft enclosure is fixed to a substrate of the river, a buoyancy structure is arranged at the top of the soft enclosure, the buoyancy structure floats on the surface of the river, thus the soft enclosure is in a bent shape or a stretching shape along with the change of the water level of the river, and the support height of the soft enclosure is adjusted; and the filtering fences are arranged at the two opposite ends of the soft enclosure, one ends of the filtering fences and the soft enclosure are slidably connected in an up-down relatively moving mode, the other ends of the filtering fences are fixedly connected with the river bank, and thus a riverside sewage drainage area is formed by the pair of filtering fences, the soft enclosure and the river bank in a defining mode. The soft enclosure capable of deforming has the buffering effect on impact force of water, the internal and external water level is balanced through the filtering fences, thus the internal and external pressure difference is small, and part of the self-purification capacity of the river can be utilized.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a river sewage intercepting device and a construction method thereof. Background technique [0002] At present, in the treatment of river sewage interception, for tidal rivers with a large difference between high and low water levels, the water level of the river changes too quickly. If ditches are built for sewage interception, high retaining walls must be formed according to the highest water level to completely isolate the river water. The high retaining wall needs to withstand the pressure difference inside and outside and the impact erosion of water, and it needs to excavate a deep foundation pit for large disturbance construction, which has high requirements on the foundation, and the buildings on both sides of the bank cannot bear it. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, to provide a rive...
