Problems solved by technology

Under normal circumstances, floor-mounted steel pipe scaffolding is used as the support for the installation and disassembly of the formwork. Therefore, the installation of equipment such as the pump at the bottom of the water intake pump room cannot be carried out simultaneously, and the safety risk is high.

Embodiment Construction

[0054] The embodiment of the present invention is illustrated by taking the No. 124 water plant relocation and water supply guarantee project in the downtown area of ​​Yibin City as the ultra-deep and large-span circular water intake pump well ring project of the Pu'an Water Plant. This embodiment realizes the mechanical and electrical facilities for water intake at the bottom of the well The installation was carried out simultaneously with the construction of the well ring, as well as the protection of the equipment and facilities at the bottom of the pump room. During the construction process, the goal of the construction period was accelerated, and the safety risk of the high formwork support was also reduced, which was unanimously received by the owner, design and supervision units. praise.

[0055] The materials used in this embodiment are mainly materials such as formwork and section steel, as shown in Table 2.

[0056] Table 2 Main material and equipment list

Abstract

The invention relates to the field of water taking facilities in a construction period of a tap water plant or a water pumping room, and in particular to a method for constructing a water pumping roomwalling crib concrete drawing die. The method adopts a non-bracket die-drawing die-turning construction method matched with a tower crane, the rapid construction of a ultra-deep large-span circular water pump well crib is realized, the construction quality and the construction period of the water pumping room walling crib are guaranteed, the construction difficulty of uninterrupted construction for installation of the pumping room equipment room is successfully solved, the parallel operation and the construction period optimization are achieved to the greatest extent, significant effects areachieved in aspects of process optimization, cost saving and progress control, the synchronous construction of installation of the pumping room equipment facilities and the well crib is realized, andmeanwhile, effective measures are adopted to reduce the safety risk.

Description

technical field [0001] The invention relates to the field of water intake facilities during the construction period of a waterworks or a pump house, in particular to a concrete drawing form construction method for a well circle of a water pump house. Background technique [0002] The water intake pump is an important part of the construction of a new waterworks, and it is directly related to the durability and construction period of the water intake pump room structure of the waterworks. The water intake pump room is generally divided into two parts: the hidden well under the ground level and the open well on the ground level. Under normal circumstances, floor-mounted steel pipe scaffolding is used as the support for the installation and disassembly of the formwork. Therefore, the installation of equipment such as the pump at the bottom of the water intake pump room cannot be carried out simultaneously, and the safety risk is high. Therefore, how to take effective measures ...
