AI Technical Summary

Technical Problem

Ship locks face potential risk of staggering when crossing active faults, resulting in uneven structural stress, which may cause structural cracks, tilts, and damage, interrupt waterway transportation and cause economic losses and casualties.

Method used

A ship lock pass-moving fault structure based on the concept of flexible absorption is designed. By dividing the lock chamber into long and short sections, and connecting sections are alternately arranged between them. The connecting section adopts a multi-layer structure including an outer surface enclosed coating, a flexible foam board, a multi-directional flexible concave corrugated steel plate, a pebble thick cushion layer, an anti-seepage layer and a concrete leveling layer to absorb the displacement of the fault.

Benefits of technology

Under the action of tension and shear, this structure can maintain the safe and stable operation of the lock, adapt to various fault staggered deformation, avoid damage to the main structure, extend the service life, and prevent water from seeping in extreme cases, reducing the risk of weakening the foundation bearing capacity.

Abstract

The invention provides a ship lock active fault passing structure based on a flexible absorption concept and an operation and construction method. The ship lock active fault passing structure comprises lock chamber sections with different lengths and connecting sections between the sections. The connecting section is composed of an outer surface closed coating, an upper flexible foam plate, a multi-direction flexible concave corrugated steel plate, a lower flexible foam plate, a pebble bed, an impermeable layer and a leveling layer from top to bottom. The connecting sections of the water delivery galleries are connected through square corrugated pipes; the multidirectional flexible concave corrugated steel plate is a main part for absorbing displacement, a plurality of U-shaped corrugations are axially arranged on the multidirectional flexible concave corrugated steel plate, the vertical steel plate and the horizontal steel plate in the cross section are connected through the S-shaped corrugations, and the corrugated plate has large displacement compensation capacity and can meet the spatial displacement requirement of the structure. According to the structure, multiple layers of waterproof and waterproof measures are adopted, rigidity and flexibility are combined, the structure can adapt to long-term small deformation of a fault, large deformation caused by earthquake damage is reduced, damage is concentrated on the connecting section, damage to a ship lock main body structure is avoided, later repair is facilitated, and safe and stable operation of the ship lock when the ship lock passes through the active fault is ensured.
