Access door for large-span lock chamber

Abstract

The invention discloses an access door for a large-span lock chamber. The access door comprises a plurality of sections of gate leaf structure sheet bodies arranged on the lock chamber, a gate groove structure arranged on the lock chamber and matched with the plurality of sections of gate leaf structure sheet bodies, and a water stop system arranged on the lock chamber and used for preventing river water from being poured into the lock chamber during maintenance, a narrowing part capable of reducing the space occupied by the lock chamber is arranged at the bottom of each section of gate leaf structure sheet body, and the narrowing part and each section of gate leaf structure sheet body are of an integrated structure. The access door has the beneficial effects of small space occupation of the lock chamber, wide applicability, energy and material consumption saving, investment saving, small influence on the surrounding environment and simplicity and convenience in construction.

Description

technical field [0001] The invention relates to the fields of water conservancy engineering, shipping engineering and the like, in particular to an access door for a large-span lock chamber. Background technique [0002] The purpose of the maintenance door in the sluice and ship lock engineering is: 1. It is designed for the maintenance of the working gate and its door slot, as well as the reinforcement and reconstruction of the main door slot. 2. In the inspection of the internal underwater structure of the sluice chamber and the reinforcement of the sluice chamber, the inspection and maintenance of the floor of the sluice chamber and the anti-carbonation construction of the side piers of the sluice chamber are required. However, with the development of social economy and the advancement of science and technology, there are more and more single-hole and large-span sluices and ship locks under construction. More than 20m, common steel dam gates and flap dams have a single-s...

AI Technical Summary

Problems solved by technology

However, with the development of social economy and the advancement of science and technology, there are more and more single-hole and large-span sluices and ship locks newly built or under construction. The single-span net width of the common steel dam gate and flap dam is also more than 20m. Due to the large span, the traditional flat steel gate or stacked beam gate can no longer meet the needs of the gate chamber maintenance. For this type of long-span gate The inspection and maintenance of the lock chamber needs to build cofferdams on the upstream and downstream of the lock chamber to carry out the maintenance of the underwater engineering of the lock chamber, and the safety production and quality control of the project are difficult, the progress is slow, and the maintenance cost is high
