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...

specific Embodiment approach

[0048] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: The following is a specific explanation of the structure defined in the present invention with reference to the contents of the drawings in the specification.

[0049] The invention provides a gate hoisting construction method used in a narrow working space. The construction method utilizes the upper cavity of the gate to hoist the gate, and is used for construction in a narrow space after the top of the upper cavity of the gate is poured. In order to adapt to the narrow working space, The gate is hoisted in sections, the gate is hoisted from the gate slot, and the short side is used for hoisting, and the upper cavity of the gate is rotated to carry out the hoisting construction of the gate, which specifically includes the following construction steps:

[0050]S1: Process the gate segment, the gate includes the first segment 1, the second segment 2 and the third segment 3 arranged from top to bottom, the first segment 1,...

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...
