A pump room 13 is formed on the left side of the water-resistant wall 12, and a water tank 14 is formed by splicing the water tank module 2 on the right side of the water-resistant wall 12. The inner wall of the water tank 14 is waterproofed. An inlet 15 is cast at the top of the body 11, and an inlet room module 3 is stacked at the inlet 15. A first assembly port 16 is precast at the bottom of the body 11, located on the right side of the water-resistant wall 12, and a second assembly port 17 is precast at the bottom of the body 11, located on the left side of the water-resistant wall 12. A pre-formed first water collection pit 161 is embedded in the first assembly port 16, and a pre-formed second water collection pit 171 is embedded in the second assembly port 17. A pump pipe 18 and an inlet pipe 19 are installed at the water-proof wall 12. The pump pipe 18 is located at the lower part of the water-proof wall 12. The pump pipe 18 bends downward and is inserted into the first water collection pit 161. The pump pipe 18 and the inlet pipe 19 are waterproofed at the contact points with the water-proof wall 12. A grouting groove 199 is formed between the first assembly port 16 and the first water collection pit 161, and between the second assembly port 17 and the second water collection pit 171. Waterproof grout is injected into the formed grouting groove 199.

[0042] In the above technical solution, the main body 11 is a precast concrete component, which is cast and shaped in the factory and transported to the construction site by freight, and then directly hoisted into the foundation pit for installation.

[0043] The corresponding first water collection pit 161 and second water collection pit 171 are both prefabricated components, installed along with the main body 11, and waterproof grout is poured into the grouting groove 199 formed by assembly to form a waterproof seal.

[0044] A water-resistant wall 12 is used to separate the pump room 13 and the water tank 14.
