Problems solved by technology
[0003] The pump station is usually installed on the external foundation, that is, a well pit needs to be excavated at the foundation, and the pump station is hoisted to the well pit for installation. After the external well pit is opened, due to the nature of the foundation, the foundation may collapse or subside. Therefore, During construction, it is necessary to support the well pit first, and installing a support structure at the well pit can improve the stability of the well pit; however, the usual support structure is an integrated structure, which is inconvenient to install

Embodiment Construction
[0047] The following is attached Figure 1-6 The application is described in further detail.
[0048] The embodiment of this application discloses a support structure for an integrated prefabricated pumping station caisson. figure 1 , the support structure for the caisson of the integrated prefabricated pumping station includes a well pit 01 excavated in the foundation 0, and a fine sand layer 02 is laid on the bottom wall of the well pit 01. In the embodiment of this application, the fine sand layer adopts a diameter of 0.2mm The fine sand layer 02 is pressed against the bottom wall of the well pit 01 and compacted. The well pit 01 is located above the fine sand layer 02 and is provided with a support structure 1. The support structure 1 includes several support components 2, and several The supporting components 2 are sequentially attached and arranged.
[0049] refer to figure 1 , figure 2 and image 3 The support assembly 2 includes a support plate 21 and a support s...

The invention relates to a supporting structure for an integrated prefabricated pump station open caisson and a construction method applying the supporting structure. The supporting structure comprises a well pit formed in a foundation, wherein the supporting structure is arranged in the well pit; the supporting structure comprises a plurality of supporting assemblies, each supporting assembly comprises a supporting plate and a supporting steel plate, the supporting assemblies are located above the bottom wall of the well pit, a positioning block is arranged on the face, away from the bottom wall of the well pit, of each supporting plate, an inserting groove is formed in one end of each supporting steel plate, and the positioning blocks can be inserted into the inserting grooves of the supporting steel plates; receding grooves are formed in the supporting plates, an extending plate is arranged on one side of each supporting steel plate, the extending plates can be inserted into the receding grooves, and the extending plates are matched with the receding grooves; and fixing bolts are arranged on the supporting steel plates in a penetrating mode, the fixing bolts are in threaded connection with the positioning blocks, the fixing bolts penetrate through the positioning blocks and are in threaded connection with the side walls of the supporting steel plates, and the multiple supporting assemblies are sequentially arranged in an attached mode. The supporting structure has the effect of improving the installation convenience of the supporting structure.
Description
technical field [0001] The application relates to the field of pumping station caisson construction, in particular to an integrated prefabricated pumping station caisson support structure and a construction method using the support structure. Background technique [0002] The integrated pumping station is an equipment that integrates various components. It is produced and assembled by the factory in a unified manner, and it is shipped to the site for direct installation. The main components are GRP glass fiber reinforced plastic cylinder, submersible pump, top cover, base, grille, and service platform. And pipe valves and other components. The function of the integrated pumping station is mainly to pressurize and discharge sewage, rainwater, drinking water, and waste water, which is often referred to as the "lifting effect" in the industry. [0003] The pump station is usually installed on the external foundation, that is, a well pit needs to be excavated at the foundation,...
