Method of Strengthening the Foundation of Concrete Guide Wall

Abstract

The invention discloses a method for reinforcing the foundation of a concrete guide wall, which includes: dividing the guide wall foundation at a preset distance from one side of the concrete guide wall into a plurality of wall sections along a direction parallel to the axial direction of the concrete guide wall; For each wall section, the bottom bedrock expansion pile construction is carried out with two pile holes as a group, so as to obtain the lower connection of two anti-scour piles corresponding to the wall section with multiple groups of anti-scour piles and each group of anti-scour piles An integrated anti-seepage pile wall; a plurality of anti-seepage pile walls obtained by constructing multiple wall sections form an anti-seepage wall for strengthening the foundation of the concrete guide wall. The method of the invention forms an anti-seepage wall at the bottom of the original concrete guide wall, and completely solves the problem of brushing the foundation of the guide wall.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a method for reinforcing the foundation of a concrete guide wall. Background technique [0002] my country has a vast territory, a large population, shortage of water resources, large differences in time and space distribution, and frequent floods and droughts. For a long time, our people have benefited from water and suffered from water, and have fought against floods and droughts for a long time. Since the founding of the People's Republic of China, water conservancy construction has made remarkable achievements. There are many various types of power stations in operation. During the long-term operation of the power station, affected by hydraulic erosion, the foundation of the concrete guide wall is washed away, and hollowing occurs in some areas at the bottom. [0003] However, if the bottom of the guide wall of the hydropower station is hollowed o...

Problems solved by technology

[0003] However, if the bottom of the guide wall of the hydropower station is hollowed out, there will be a void area at the bottom, which will cause a hydraulic connection between the inside and outside of the guide wall, which will greatly affect the service period and service safety of the hydropower station.
