Description
Technical Field
The utility model relates to the technical field of civil engineering, in particular to a device for improving mud water and mud out of a pipe jacking through soil pressure balance.
Background
The pipe-jacking construction is a construction method of underground pipelines developed after shield construction, does not need to excavate a surface layer, can pass through roads, railways, rivers, ground buildings, underground structures, various underground pipelines and the like, and is more and more widely applied to the construction of pipelines for water supply and drainage, gas, power, communication and the like.
Because the unearthing mode of the earth pressure balance push bench is earth box earth carrying, a winch and a small earth box are needed, the earth carrying distance is far away to reduce the tunneling speed of the push bench along with the increase of the tunneling length of the push bench, the work efficiency is poor, and great safety risks exist in long-distance earth carrying and vertical earth box transporting.
Disclosure of Invention
The utility model provides a device for improving mud and water to output slurry by using soil pressure balance pipe jacking, aiming at solving the technical problems of low tunneling speed and poor work efficiency of a pipe jacking machine caused by long soil transporting distance in the existing soil box soil transporting mode.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a device that balanced push pipe of soil pressure changes muddy water and goes out mud, is including setting up in the agitator of push bench screw hole department, install the steel filter screen in the agitator, be located and install automatic lifting device on the agitator inside wall of steel filter screen below, the top of agitator is provided with the inlet tube, and the bottom of agitator is connected with out the mud pipe, the agitator still is connected with the hydraulic pump with the junction that goes out the mud pipe.
The working principle and the process are as follows: the installation steel filter screen can filter the miscellaneous filler of bold in the soil layer to adopt automatic lifting device installation steel filter screen to go up out the agitator after, clear away the miscellaneous filler of bold, inlet tube and agitator are gone into the top and are gone out native and stir into mud, through hydraulic pump connection agitator and play mud pipe, utilize the pressure of hydraulic pump with mud discharge push pipe tunnel, thereby form the mode of mud outward transport, promote the push pipe greatly and tunnel out native efficiency.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model can ensure the principle of soil pressure balance on the front side of the pipe jacking machine, can simultaneously discharge slurry to ensure continuous tunneling of the pipe jacking machine, can accelerate the pipe jacking tunneling speed, and can avoid safety risks caused by long-distance soil transporting and vertical transporting.

The figures are labeled as follows:
the method comprises the following steps of 1-pipe jacking machine, 2-pipe jacking machine screw port, 3-water inlet pipe, 4-stirring barrel, 5-steel filter screen, 6-hydraulic pump, 7-slurry outlet pipe, 8-automatic lifting device, 9-vibrator and 10-pipe jacking pipe joint.
Detailed Description
The present invention is further illustrated by the following specific examples.
Examples
As shown in figure 1, a device for improving mud water and discharging slurry through earth pressure balance jacking pipe, including setting up in agitator 4 of push bench screw mouth 2 department, be equipped with the stirring rake in agitator 4, install steel filter screen 5 in agitator 4, be located and install automatic lifting device 8 on the 4 inside walls of agitator of steel filter screen 5 below, agitator 4's top is provided with inlet tube 3, and agitator 4's bottom is connected with out mud pipe 7, agitator 4 still is connected with hydraulic pump 6 with the junction of going out mud pipe 7.
Further, vibrator 9 is installed to the bottom of steel filter screen 5, and vibrator 9 during operation makes steel filter screen 5 be in vibration state, is convenient for clear away the miscellaneous thing of bold filling.
Further, automatic lifting device 8 is the promotion hydro-cylinder, the quantity that sets up of promotion hydro-cylinder is at least three, and the flexible end of all promotion hydro-cylinders is connected with the bottom edge of steel filter screen 5, and the flexible end stretching speed of at least one of them promotion hydro-cylinder is greater than the stretching speed of other promotion hydro-cylinders.
As shown in fig. 2, the number of the lifting cylinders is three, the telescopic speed of the telescopic end of one of the lifting cylinders is higher than that of the other lifting cylinders, when the telescopic end is lifted simultaneously, the steel filter screen 5 is in an inclined state, and simultaneously, the screened large impurity fillers are quickly cleaned under the vibration action of the vibrator 9.
Installation steel filter screen 5 can filter the miscellaneous filler of bold in the soil layer to adopt automatic lifting device 8 installation steel filter screen 5 to rise out the agitator 4 after, clear away the miscellaneous filler of bold, inlet tube 3 and agitator 4 stir into mud to the soil of passing in and out of the top, connect agitator 4 and play mud pipe 7 through hydraulic pump 6, utilize hydraulic pump 6's pressure to push up the pipe tunnel with mud discharge, thereby form the mode of mud outward transportation, promote the push pipe greatly and tunnel out of soil efficiency.
