A maintenance platform for a flood discharge channel of a hydropower station and its erection method

Abstract

The invention discloses a maintenance platform for a flood discharge channel of a hydropower station and a method for erecting the same. A front winch is fixedly installed on the bottom frame of the front section, bottom wheels are respectively installed at four corners of the bottom of the bottom frame of the front section; The tail of the front section chassis is fixedly connected through the No. 1 threaded flange plate; the head of the tail section chassis is fixedly connected with the tail of the intermediate connection chassis through the No. 2 threaded flange plate; the tail section chassis is fixed on the A rear winch is installed, bottom wheels are respectively installed at the bottom four corners of the bottom frame of the tail section; bottom plate screw rods are respectively installed at the bottom four corners of the middle connection bottom frame, and bottom wheels are installed at the bottom bottom of the middle connection bottom frame. By using the flow channel maintenance platform, the construction workload can be greatly reduced, manpower can be saved, the bottom plate of the flow channel can be protected from damage, and the erection method is simple, the operation is convenient, and the safety of the maintenance platform is improved.

Description

technical field [0001] The invention relates to hydraulic structure construction equipment and a construction method thereof, in particular to a maintenance platform for a flood discharge channel of a hydropower station with limited lifting conditions and a relatively large slope and a construction method thereof. Background technique [0002] During the maintenance of the flood discharge channel of the hydropower station, due to the constraints of the construction conditions and the construction environment, it is necessary to build a maintenance platform to carry out the maintenance of the flood discharge channel. At present, scaffolding steel pipes are usually used to set up a full scaffolding method in the entire flow channel for the maintenance of the flow channel. [0003] There are several defects in the following aspects of maintenance using the above method: (1) Since the erection of scaffolding requires a lot of manpower and material resources, and with the increas...

AI Technical Summary

Problems solved by technology

[0003] There are several defects in the following aspects of maintenance using the above method: (1) Since the erection of scaffolding requires a lot of manpower and material resources, and with the increase of the length of the flow channel, the amount of work will further increase, which will cause an increase in construction costs; (2) Since this method needs to implant steel bars on the bottom plate of the flood discharge channel to fix the scaffolding, and then remove the steel bars after the construction is completed, holes will be left on the bottom plate, which will have a certain impact on the quality of the channel bottom plate (3) Using erected scaffolding for construction may cause certain safety hazards to subsequent construction due to erection quality problems; (4) Scaffolding is inconvenient to move during construction, thereby affecting construction schedule
