Gate lifting construction method for narrow operation space

Abstract

The invention discloses a gate lifting construction method for narrow operation space. For gate installation in narrow operation space, an upper cavity of a gate is used as rotating construction space; first and second sections of the gate are firstly lifted; short edges are used for lifting; the upper cavity is placed at the upstream or the downstream of a gate groove after rotation to reserve mounting space of the gate groove; then, a third section is lifted by using a short edge; after the third section is rotated in the upper cavity, the third section is placed down into the gate groove; then, the second and first sections are lifted in sequence and placed in the gate groove in sequence to realize the assembly molding of the sectioned gate; and the narrow upper space of the gate groovecan be fully used, so that the operation efficiency is improved.

Description

technical field [0001] The invention relates to a construction method for hoisting a gate in a water conservancy project, in particular to a construction method for hoisting a gate in a narrow working space. Background technique [0002] Gates are the main structural components of water retaining and water storage projects in water conservancy projects. Common forms of gates include flat gates, arc gates or flap gates, etc., which are generally installed in gate slots. In practice, lifting methods are often used. Hoisting: The gate is hoisted into the gate slot and then assembled. According to the hoisting space or hoisting force, it can be assembled in sections or assembled as a whole and then hoisted. The above-mentioned operation method requires a relatively large operation space, requires corresponding hoisting space above the gate slot, and often requires fixed hoisting equipment. [0003] In the construction of gate buildings, a hoist machine room is often built on th...

Problems solved by technology

[0003] In the construction of gate buildings, a hoist machine room is often built on the upper part of the gate slot. The bottom plate of the hoist machine room and the upper part of the gate slot form the upper cavity of the gate. , the construction of the hoist room will waste the construction period; if the hoist room is built in advance, the space for hoisting the gate will be narrow, and the general hoisting method cannot be realized. When building a building, using the narrow upper cavity of the gate to carry out the hoisting operation of the gate is a practical engineering technical problem that needs to be solved
