Problems solved by technology

[0004] The technical problem solved by the present invention is: the bedding and the sluice foundation are very prone to shear failure due to uneven settlement, and a closed composite geomembrane anti-seepage system is installed at the connection between the bedding and the sluice foundation, and the composite geomembrane is used High ductility and high anti-seepage performance, when there are cracks in the pavement due to uneven settlement, the composite geomembrane can still continue to work to protect the normal operation of the anti-seepage system

Abstract

The invention discloses a combined anti-seepage structure for a culvert and a construction method thereof. The combined anti-seepage structure for the culvert and the construction method thereof are used for resisting seepage of the culvert and protecting a self anti-seepage system. The anti-seepage system comprises an original anti-seepage structure, a concrete or clay bedding, an anti-seepage structure protection system and a composite geomembrane structure; the adopted main technical scheme is that, a composite geomembrane is paved between a culvert foundation and an upstream anti-seepage bedding, the geomembrane is in seal connection with the bedding and a bottom plate in the horizontal direction, and paved in a stair shape in the perpendicular direction, so that a remaining width for jointly deformation of a membrane and a soil mass is reserved on the geomembrane, and an anti-seepage defense is formed at the joint of the bedding and a gate foundation. The composite geomembrane still can be normally used for preventing seepage when the bedding cracks due to unevenness and settlement.

Description

technical field [0001] The invention relates to a combined anti-seepage structure, in particular to a culvert gate anti-seepage structure and a construction method thereof. Background technique [0002] The culvert sluice is a structural form widely used in water conservancy projects, mainly including the bedding in front of the sluice, the sluice chamber and the culvert. The bedding in front of the lock chamber can increase the length of the seepage path and reduce the slope. There are usually two types of bedding: concrete bedding and clay bedding. In practical applications, due to the large mass of the lock chamber itself and the thrust of the embankment filling on the lock chamber, uneven settlement often occurs at the joint between the lock chamber bottom plate and the bedding. Engineering experience shows that the accumulative uneven settlement of culvert sluice chambers built on the Yellow River 20 years ago is generally between 10 and 20 cm, which exceeds the allowa...
