Automatic pre-mixing self-compacting cement soil fertilizer groove backfilling system and construction method

Abstract

The invention relates to an automatic premixed self-compacting cement soil fertile groove backfilling system, and belongs to the field of building construction, the system comprises a positive construction area and a fertile groove backfilling construction area, a cement soil processing system is arranged in the positive construction area, and the cement soil processing system comprises a cement soil solidification stirring device, a slurry stirring tank and a soil storage tank; the soil storage tank is used for storing sludge generated by construction in a positive construction area, the slurry stirring tank is used for preparing cement curing agent slurry, and the cement soil processing system further comprises a storage tank; and a backfilling pipeline is arranged in the fertilizer groove of the fertilizer groove backfilling construction area, the backfilling pipeline is communicated with the discharging opening of the storage tank through a cement soil conveying mechanism, and the self-compacting cement soil is conveyed into the backfilling pipeline through the cement soil conveying mechanism. The invention further relates to a construction method of the automatic premixed self-compacting cement soil fertile groove backfilling system. The automatic premixed self-compacting cement soil fertile groove backfilling system has the beneficial effects that the fertile groove can be conveniently backfilled, and the time and cost required by fertile groove backfilling are shortened.

Description

technical field [0001] The application relates to the field of building construction, in particular to an automatic ready-mixed self-compacting cement-soil fertilizer tank backfill system and a construction method. Background technique [0002] The fertilizer trough, the part that is excavated more to provide the working surface, generally refers to the space between the outer wall of the basement of the building or the outer wall of the foundation and the edge of the foundation pit. The backfilling time of the fertilizer tank is generally done in the basement, and it is backfilled after the waterproofing construction is completed. The traditional backfilling of the fertilizer tank is mostly backfilled with 2:8 lime soil and tamped by a tamping device. [0003] However, with the continuous development of the city, the land use is becoming more and more tense, resulting in a relatively narrow construction area, which also makes the area of ​​the fertilizer tank formed after ...

AI Technical Summary

Problems solved by technology

[0003] However, with the continuous development of the city, the land use is becoming more and more tense, resulting in a relatively narrow construction area, which also makes the area of ​​the fertilizer tank formed after the construction of the basement structure narrow, with a width within the range of 0.8-1.2 meters. If the traditional 2: 8 Lime soil backfill cannot be effectively compacted

At the same time, when backfilling the fertilizer tank, it needs to be transported by vehicles. In the case of a narrow construction area, it is impossible to form a good backfilling work surface around the fertilizer tank, and it is difficult for the vehicle loaded with dust to drive into the surrounding area of ​​the fertilizer tank, resulting in The current fertilizer tank is difficult to backfill, the construction quality is low, and the construction period is long
