Method for manufacturing energy storage underground water tank and support member for energy storage underground water tank

Abstract

The invention relates to a method for manufacturing an energy storage underground water tank, which comprises the following steps: firstly excavating a pit with the depth of below 0.5m on the ground according to the required area of the water tank, adjacently connecting more than six support modules for constituting a support member, placing in the water tank, overspreading the bottom of the tank, flushing the bottom of the tank with water, using a water pump to pump slurry, enabling the support member to sink down along with pumping of the slurry, further placing another support member, fixing the support member with the lower layer, repeating the operation till achieving the required depth of the water tank, fully emptying the slurry at the bottom of the tank, pouring a concrete layer with the thickness of 50-250mm at the bottom of the tank and covering a heat insulation cover plate at the upper part of the support member at the uppermost layer, wherein each support modular is in a framework structure with above six surfaces, openings communicated with a hollow core part are arranged on the upper and the lower surfaces and at least two side surfaces of each support module, and the closed surface is arranged on one side of each support module, which faces to the wall of the tank. By adopting the method, the construction workload can be reduced, the using amount of reinforced concrete can be reduced, and the structure of the water tank is stable.

Description

technical field [0001] The invention relates to a manufacturing method of an energy-storage underground pool and a supporting member used for the energy-storage underground pool, belonging to the technical field of air-conditioning systems. Background technique [0002] With the development of modern industry and the improvement of people's living standards, the popularity of central air-conditioning is becoming more and more widespread, and its power consumption is also increasing. In some large and medium-sized cities, the central power consumption has accounted for 20% of its peak power consumption. The above causes the peak-to-valley load difference of the power system to increase, the load rate of the power grid to drop, and the power grid has to implement power cuts, which has an adverse impact on people's normal production and life. One of the effective ways to solve this problem is to apply energy storage technology to transfer the power consumption of air conditione...

AI Technical Summary

Problems solved by technology

Therefore, the structure of the energy storage pool mainly has two disadvantages: 1. The force of the pool is complex and the force span is large

Since the energy storage pool of this structure is built underground and adopts a rigid reinforced concrete structure, it is subject to groundwater buoyancy, its own gravity, the support force of load-bearing ground piles, the outer soil pressure of the surrounding facade, the water pressure in the inner pool, the ground covering soil pressure and other factors. The different shear forces formed by the different settlement velocities at each point, the transverse and longitudinal shear forces formed by the influence of seismic waves, etc., all make the force calculation of the underground energy storage tank very complicated, so many safety factors are considered in the design and manufacture. The safety factor is large, and the structure and configuration requirements are very high

Furthermore, due to the large area of ​​the pressure-bearing surface of the energy storage pool, the force span is relatively large. In order to maintain the stability and safety of the structure, a large amount of reinforced concrete is used.

2. The pool cost per unit volume is high

At present, the energy storage pool requires large-scale excavation construction, waterproofing, slope protection, etc., which makes the construction cost relatively high. In addition, due to the large amount of reinforced concrete used in this method, the cost of the pool is as high as 1,000 yuan / m3

3. Limited by the terrain and structure, the volume of the energy storage pool is limited

Due to the limitation of the project site and the characteristics of the energy storage pool, the volume of the underground energy storage pool is generally thousands of cubic meters, so the energy storage capacity of the air conditioning system that can be provided is extremely limited, generally only enough for one building or several adjacent buildings. The energy supply demand of each building cannot meet the requirements of regional energy supply
