Device and method for quickly constructing small water cellar

Abstract

The invention discloses a device and a method for quickly constructing a small water cellar. The device disclosed by the invention comprises an inflatable air bag corresponding to the inner wall of the water cellar and a steel pipe for inflating the air bag, wherein the steel pipe is inserted into the air bag and is fixedly connected with an upper port and a lower port of the air bag in a sealing manner. The method for quickly constructing the small water cellar by use of the device comprises the steps of excavating a foundation pit, pouring to form a cellar bottom, putting a constructing device, charging air at 5-6kpa to the device, pouring to form cellar walls and a cellar top, sucking air in the device and taking out the device; using cement mortar, waterproof mortar and cement to treat fine aggregate concrete inner walls; and finally, mounting a cellar cover. The device and the method for quickly constructing the small water cellar have the characteristics of the structure is simple, the use is convenient, the labor can be saved, the cost is reduced, and the construction period is shortened. In addition, the constructed water cellar is firm and durable.

Description

technical field [0001] The invention belongs to the technical field of water cellar construction, and particularly designs a rapid construction device and method for a small rain-collecting water cellar. Background technique [0002] The rainwater storage and utilization project mainly refers to the micro-water conservancy project that collects and stores the precipitation in and around the planning area in arid, semi-arid or seasonal drought and water shortage areas, and effectively uses it as a water source for domestic or production water in the planning area. project. [0003] Rainwater harvesting has a long history at home and abroad. China, the United States, Japan, Germany, Canada, India, Australia, and some African countries are using natural slopes to build micro catchment areas to collect rainwater. In the hilly and mountainous areas of my country's Loess Plateau, southwest mountainous areas, and coastal water-deficient island areas, people use various water stora...

AI Technical Summary

Problems solved by technology

This kind of formwork has the following disadvantages: 1. The structure is extremely complex. In order to achieve the required deformation of the formwork, a large number of adjustments must be made to the rigging behind the formwork, so it is extremely inconvenient to use; 2. It is difficult to form a two-dimensional form that meets the requirements. Curved surface; 3. The template combination is complex and difficult to disassemble; 4. The rigging of the template brings a lot of inconvenience to the concrete construction

Although this combined formwork partially solves the technical problems of complicated operation and inconvenient construction, it still has the following deficiencies: 1. The time difference between the construction of the bottom of the cellar and the wall of the cellar is too large, which easily causes the concrete strength of the bottom of the cellar and the wall of the cellar to be different, thereby 2. The template making process is complicated, the cost is high, and the template assembly is time-consuming and laborious

[0012] At present, there is a lack of a small water cellar rapid construction device and method that is simple in structure, easy to use, and can reduce costs and shorten construction periods
