Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a fluidized solidified soil construction system and a construction method. Background Art

[0002] Fluidized solidified soil is a new type of building material. It is a pumpable fluid reinforcement material formed by mixing engineering slag with solidifying materials and water, and mixing them evenly with special machinery. It has strong fluidity before solidification, and has certain strength, low permeability and water stability after solidification. It can maintain long-term stability and has the characteristics of low carbon and environmental protection. This material is widely used in engineering for backfilling and pouring in complex working conditions such as foundation trenches, foundation pits, and mine pits.

[0003] In the construction of fluidized solidified soil, it is necessary to prepare finished fluidized solidified soil that meets the requirements. The existing process usually mixes and stirs the solidified materials, water, soil and other materials according to the specified ratio to make the finished product. The corresponding equipment and process design are unreasonable, the manual participation is high, and the work efficiency is low. In this process, it is necessary to evaluate the workability of the prepared mud to meet the pouring requirements. Usually, manual sampling is used to judge its workability by expansion or slump. There is a lack of unified standards, and then water is added based on experience. This method relies on manual calculation of fluidity, water addition amount calculation, and water addition operation, which has the problems of large errors, time-consuming and labor-intensive, and low work efficiency. Summary of the invention

[0004] In view of this, in order to solve the above-mentioned technical problems, the present invention proposes a fluidized solidified soil construction system and a corresponding construction method which have reasonable structural design, high degree of automation, low manual participation, high work efficiency, and can automatically monitor the fluidity in the preparation process of fluidized solidified soil, automatically and quantitatively replenish water and add solidifying materials, reduce human errors, and realize automatic adjustment of the working performance of fluidized solidified soil.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] The present invention provides a fluidized soil solidification construction system, comprising:

[0007] The original soil slurry making area includes an original soil slurry making pool, a water supply pipeline for supplying water to the original soil slurry making pool, a stirring device for stirring the slurry in the original soil slurry making pool, and an internal circulation pipeline for obtaining the volume of slurry passing through the pool per unit time;

[0008] A stirring and slurrying area, the stirring and slurrying area includes a stirring tank, a powder feeder for feeding solidified materials into the stirring tank, a second water supply pipeline for supplying water to the stirring tank, and a second internal circulation pipeline for obtaining the volume of slurry passing through per unit time;

[0009] A conveying pipeline 1, wherein the conveying pipeline 1 can convey the slurry in the raw soil slurry making pool to the mixing tank;

[0010] A fluidized soil backfill standby area, wherein the fluidized soil backfill standby area is used to store finished fluidized solidified soil;

[0011] A second conveying pipeline, wherein the second conveying pipeline can convey the fluidized solidified soil in the mixing tank to the fluidized soil backfill standby area;

[0012] A controller, wherein the controller can obtain the mud passing volume per unit time fed back by the internal circulation pipeline 1 and the internal circulation pipeline 2, and can control the operation of the water replenishment pipeline 1, the water replenishment pipeline 2, the powder feeder, the conveying pipeline 1, and the conveying pipeline 2.

[0013] The original soil slurry making area is responsible for slurry making. The slag stored in the site or purchased outside the site is transported to the original soil slurry making pool and mixed with water to make slurry. The original soil slurry making pool can be manufactured on site, with a designed volume of about 2m×2m×2m. The original soil slurry making area can also be responsible for processing off-site mud. The original soil slurry making area can realize automatic adjustment of the water content of the mud. The slag and a small amount of water are poured into the original soil slurry making pool, and the initial mud is fully stirred to form the initial mud. The internal circulation pipeline obtains the mud passing volume per unit time and feeds it back to the controller. The controller calculates the mud water content through the built-in algorithm (there is a corresponding relationship between the mud passing volume (pumping flow) per unit time and the mud water content), obtains the required water replenishment amount, and the controller controls the water replenishment pipeline to replenish a certain amount of water. The controller receives the mud passing volume per unit time fed back by the internal circulation pipeline again, and judges whether the mud fluidity meets the standard based on this value. If it meets the standard, the conveying pipeline is controlled to convey the mud to the stirring slurry area.

[0014] The mixing and slurrying area is responsible for mixing and stirring the slurry and the solidifying material to prepare the fluidized solidified soil; the mixing and slurrying area is the core area for the preparation and performance adjustment of the fluidized solidified soil. The internal circulation pipeline 2 obtains the volume of mud passing through per unit time and feeds it back to the controller. Based on this value, the mud fluidity index is judged. The controller obtains the required amount of solidifying material through the built-in algorithm. The powder feeder puts the target mass of solidifying material into the mixing tank through precise quantitative rotation and fully stirs it. The controller receives the volume of mud passing through per unit time fed back by the internal circulation pipeline 2 again, and judges whether the mud fluidity meets the standard based on this value. If it meets the standard, the conveying pipeline 2 is controlled to convey the mud to the fluidized soil backfill standby area (the water replenishment process is similar: the internal circulation pipeline 2 obtains the volume of mud passing through per unit time and feeds it back to the controller. Based on this value, the mud fluidity index is judged. The controller calculates the water content of the mud through the built-in algorithm. If the requirements are met, no water replenishment is required. If the requirements are not met, the required water replenishment amount is calculated, and the controller controls the water replenishment pipeline 2 to quantitatively replenish water).

[0019] The controller controls the mud pump 1 to work, and the magnetic flowmeter 2 measures the volume of mud passing through per unit time and feeds back to the controller.
