Problems solved by technology

[0003] The installation of the door slot in the second phase needs to roughen the concrete joint surface of the first phase and the second phase; when the chisel and the door slot are installed, a scaffolding construction platform needs to be erected, which takes up a lot of straight-line construction period and affects the construction period of the civil construction. Cross-operation, highlighting safety risks
The second phase of concrete damage caused the quality problem of gate groove damage, which has important hidden dangers to the safe operation of the project

Embodiment Construction

[0108] Such as Figure 1~Figure 21 Among them, a first-phase installation method of the gate slot of a hydropower station, which includes the following steps:

[0109] Step 1, install the sill 1; stake out the benchmark, adjust the height and mileage of the sill 1; support the sill 1;

[0110] Step 2, installation of main rail 2 and counter rail 3; setting out installation datum; installing main rail 2; hoisting jack-up trolley 5; installing counter-rail 3; ;

[0111] Step 3, install the lintel 4; inspect and stake out, set the position of the lintel 4; hoist the lintel 4, measure and adjust the deviation value; fix the lintel 4;

[0112] Step 4, lifting the jack-up trolley 5; disconnect the jack-up trolley 5 to make it in a free state; turn on the linkage operation mode and lift, and continue to lift after stopping for inspection;

[0113] Step 5, the self-elevating trolley 5 is fixed; the lower hanging seat 51 is removed; the guide rail is fixed; the self-elevating trolle...

Abstract

The invention relates to a phase-I installation method for a gate slot of a hydropower station gate. A self-lifting trolley is adopted in a narrow and small space so that an embedded part is connectedinto an integrated structure and stressed jointly, and a template is automatically lifted for suspension construction through the self-lifting trolley. The installation method overcomes the problemsof large potential safety hazard and long period of cross operation caused by the traditional installation method of the gate slot of the original hydropower station requiring to weld a joint bar andinstall and disassemble a scaffold for many times, and the method has the characteristics of reducing multiple welding of the joint bar, no need to set up the scaffold, no need of cross operation, improving the safety during operation and avoiding damage to the gate slot during pouring.

Description

technical field [0001] The invention belongs to the technical field of installing a gate slot of a hydropower station, and relates to a first-stage installation method for a gate slot of a hydropower station. Background technique [0002] At present, most of the steel gate slots used in large-scale hydropower stations at home and abroad adopt the traditional second-stage door slot installation process, that is, when concrete is poured, only the first-stage inserting bars are pre-buried, and the door slot installation stations and part of the concrete are reserved for the second-stage pouring , Conservation. After all (or part) of the concrete has been poured, the scaffolding construction platform will be erected, the concrete at the junction of the first and second phases will be chiseled, and then the door slot embedded parts will be installed, and the door slot embedded parts will be installed and reinforced by the first-stage ribs, and the acceptance is passed After the ...
