The mud plays important roles of protecting the hole wall, deslagging, cleaning the hole and the like, but the construction process of the bored concrete pile is the process with the greatest mud generation and the most serious pollution. Therefore, the disposal of waste mud is always a difficult problem for pile foundation engineering construction of punched bored piles.
At present, less research is carried out on the slurry treatment of the punched bored pile, and the traditional waste slurry treatment mode mainly comprises the steps of carrying out sedimentation in a sedimentation tank and then transporting the sedimentation tank truck to suburbs to naturally weather the slurry, so that the mode not only occupies a large area, but also reduces the recycling efficiency of the slurry, and the circulating slurry has high slag content, is easy to cause hole collapse and drill sticking, and influences the construction safety production.
Disclosure of Invention
The invention aims at: the utility model provides a construction structure is handled in circulation of bored concrete pile mud that punches a hole to solve in the bored concrete pile work progress that punches a hole waste mud easily sediment, with high costs, mud treatment effeciency low and difficult recycling scheduling problem.
In order to solve the problems, such construction structure is handled in bored concrete pile mud circulation that punches a hole is to be adopted, including the mud storage pool, first shale shaker, the second shale shaker, advance the thick liquid pipe, hydrocyclone, storage tank and host computer sediment stuff pump in the mud, first shale shaker and second shale shaker all follow horizontal setting, and first shale shaker and second shale shaker set gradually in the top of mud storage pool from bottom to top, the sieve mesh of second shale shaker is greater than the sieve mesh of first shale shaker, advance in the waste slurry pond in the scene of one end of thick liquid pipe, the other end stretches to the feeding department of first shale shaker, be provided with the external pump of mud that is used for pumping thick liquid on the thick liquid pipe of advance, the discharge port of hydrocyclone stretches to the feeding department of second shale shaker, the overflow pipe of hydrocyclone is linked together with the upper end of storage tank in the mud, and the ore feed port of hydrocyclone links to each other through the feed line and the discharge port of mud bottom, and host computer sediment stuff pump sets up in the feed line, the storage tank sets up in the top of mud storage tank, the mud bottom in the mud storage tank is greater than the sieve, the feeding device is provided with the bottom of mud storage tank and the circulating pipe is stretched to the mud in the mud storage pool.
In the structure, a three-way valve is further arranged on the ore feeding pipeline at the downstream of the main machine slurry pump, two ends of the three-way valve are respectively communicated with the ore feeding pipelines at two ends of the valve, the other end of the three-way valve is connected with a slurry returning pipeline, the other end of the slurry returning pipeline extends into the slurry storage pool, and a recoil control valve is further arranged on the slurry returning pipeline.
Compared with the prior art, the invention has the following advantages:
1. The particle size of solid particles in the slurry sediment can be finely screened out by dividing the vibrating coarse screen and the vibrating fine screen through the screen mesh number, so that the separation efficiency of the vibrating screen is improved, and the energy loss is reduced.
2. Because of the complexity of the geological conditions of the construction site, the condition that the mud content in the drilling slag is higher can not meet the requirement of the mud performance exists, and the mud treated by the vibrating screen is centrifuged by the hydrocyclone, so that the requirements of mud treatment under different geological conditions can be met. Meanwhile, in the general use process, the vibrating screen can be only started, screened slurry is filtered through the slurry circulating pipe and pumped into the slurry storage tank, and then discharged, so that a hydrocyclone is not needed, when the slurry density is high, the hydrocyclone is started again, the actual use power is reduced, the cost is saved most reasonably, and the method is more economical and feasible.
3. Through the combination of the slurry circulating pipe and the three-way valve, the whole slurry treatment device is circularly optimized, and the phenomenon that the slurry is pumped out in time to cause pipe blockage and pipe cracking is avoided.
