Method for mounting down-the-hole type arc gate embedded parts and water seals

Abstract

The invention relates to a method for mounting down-the-hole type arc gate embedded parts and water seals. The method comprises the following steps of: mounting trunnion first-stage embedded parts, trunnion second-stage embedded parts and sill embedded parts, casting second-stage concrete after the trunnion first-stage embedded parts, the trunnion second-stage embedded parts and the sill embedded parts are mounted to be eligible, and hoisting side gate recesses and a gate lintel to mounting positions and firmly strengthening; hoisting gate components, adjusting and welding the gate components, ascending concrete to a hoist platform, mounting mechanical and electrical equipment for a hoist, and connecting the mechanical and electrical equipment with a gate body and carrying out joint regulation after the mechanical and electrical equipment is regulated to be qualified; regulating the side gate recesses and the gate lintel according to the regulated actual position of the gate and combining with theoretical design gaps; and determining the dimension for mounting the gate water seals and mounting the gate water seals according to the actual gaps among the gate and the side gate recesses and the gate lintel, casting second-stage concrete for the side gate recesses and the gate lintel after the requirements are satisfied, and carrying out whole-course no-water regulation on the gate and the hoist so as to ensure the mounting quality of the water seals after the casting of the second-stage concrete for the side gate recesses and the gate lintel is qualified. The method for mounting the down-the-hole type arc gate embedded parts and the water seals provided by the invention has the advantages that: the gate system is prevented from being damaged or even invalid because of the quality problem of the water seals, the quality of the high-head down-the-hole type arc gate water seals is improved, and the service life of the gate and the hoist is prolonged.

Description

technical field [0001] The invention relates to a submersible arc gate embedded part and a water-stop installation method for water conservancy and hydropower projects. Background technique [0002] In water conservancy and hydropower projects, the installation procedures and methods of submersible arc gates and embedded parts are generally as follows: after the concrete is poured to a certain height in the first phase of civil engineering, the embedded parts of the second phase of civil engineering are formed, and after the demolition and cleaning are completed, the installation control According to the order of the bottom sill, first-stage embedded parts of support hinges, support hinges, arc-shaped door slots and lintels, the order of hoisting, adjustment, reinforcement, and acceptance is completed, and the second-stage concrete is handed over to civil engineering. After the concrete age expires, hoist the support arm, gate, etc. After the civil work continues to rise to ...

AI Technical Summary

Problems solved by technology

This method has one of the biggest disadvantages, that is, when the water stop is installed, since the gate and hoist have been installed and debugged, the position has been fixed, the installation position of the water stop has been determined, and there is no room for adjustment, the water stop is often compressed unevenly, resulting in The water stop leaks or even is damaged. The vibration of the gate caused by water leakage in the working state can cause the gate to fail, and even more serious accidents
