Description

Multistage purification device for traffic engineering slurry

Technical Field

The invention relates to the technical field of traffic engineering construction devices, in particular to a multistage purification device for traffic engineering slurry.

Background

The mud purifying device is a mud purifying device; the main function is to quickly clean harmful solid phases in the engineering slurry, such as fine sand, stones, barks, grass roots, household garbage and the like; after the harmful solid phase is removed, the remained clean slurry can be returned to the engineering hole (groove) again for use.

The mud is a mud-water mixed liquid prepared by clay (mud) and water and adding different chemical agents according to a certain proportion, and the necessity of the mud is illustrated by taking bridge construction as an example. The bridge pier is located on a base of the bridge, and after a pile foundation is rotated out of a deep hole by a drilling machine, a reinforcement cage is arranged, then concrete is poured, and finally a cylinder is formed; in the process of drilling, in order to balance the pressure of underground water, mud is required; the main functions of the slurry are: 1. balancing water pressure, and forming a thin mud skin film on the hole wall to prevent collapse; 2. drill slag is suspended and carried, and drilled sand is discharged out of the hole as soon as possible by circulating mud, so that drill jamming and drill burying are prevented, and the hole forming efficiency is improved; 3. cooling the drill bit; 4. lubrication, reduction of the resistance of the drilling tool to cut the soil layer and improvement of the service life of the machine.

The full purification of the slurry is beneficial to controlling the performance index of the slurry, reducing the drilling accidents, improving the pore-forming quality, effectively separating soil and slag, improving the pore-forming work efficiency, reusing the slurry, saving the slurry-making material and reducing the construction cost; the closed circulation mode of the slurry and the lower water content of the slag materials are beneficial to reducing the environmental pollution.

The solid phase in the slurry can be divided into two types according to the action, wherein one type is a useful solid phase, such as bentonite, a chemical treatment agent and the like; another class is useless solids such as drill cuttings, poor bentonite, sand, etc. The slurry solid phase control means that harmful solid phases are eliminated and useful solid phases are preserved so as to meet the requirements of a pile foundation construction process on slurry performance; generally, slurry solid phase control is referred to simply as solid control; the solid phase particle size which has great influence on indexes such as slurry performance, mechanical drilling speed and the like is more than 15 micrometers, and accounts for about 70 percent of the total solid phase; people strive to remove the waste at any time through more effective mechanical equipment.

The prior art adopts three methods for purifying slurry:

(1) and a natural precipitation method. Digging a mud sedimentation tank, and naturally settling mud by gravity; the method is generally used for occasions with holes formed on land, the diameter of less than 1.2 meters, the pile depth of no more than 20 meters and unconcentrated fields; the disadvantages are that the waste amount of the slurry is large, and the waste slurry sedimentation tank after the project is finished is often a 'trap' for phagocytizing human lives; if the mud pit is backfilled, the overflowed mud can also cause the surrounding land to be meadow for several years.

(2) And a chemical method. Adding flocculant chemical agents into the slurry to force the slurry to be rapidly precipitated; the disadvantages are that the cost is high, the performance index of the slurry is changed, and the waste slurry after the construction has serious pollution to the environment all the time.

(3) And physical separation method. Namely, a mud purification device is used for quickly separating sand materials in mud by utilizing the centrifugal and high-frequency vibration principles; the water content of the separated sand is small, and the separated sand can be used for paving and backfilling; the discharge amount of the slurry is reduced by 80 percent, but the manufacturing cost of the equipment is higher and the maintenance cost is higher.
