Abstract
The utility model discloses a grouting device using freezing to chisel wall of well and grout at a plurality of positions quickly, which comprises a grouting pipe, a grouter, a main grouting pipe, a pipe for transporting slurry and a hose for transferring slurry. A series of grouters connected with grouting pipes are equally arranged on main grouting pipe. The upper end of main grouting pipe is connected with the pipe for transporting slurry whose upper end is connected with the hose for transferring slurry and then connected with a grouting pump on the ground near the mouth of well. Quick grouting can be carried out at a plurality of positions on the ground near the mouth of well or on wall of well by connecting the grouting pump on sinking platform in drilling well. The utility model is characterized in simple structure, convenient installation, quick grouting, high rate and significant benefits, furthermore, the utility model is also characterized in that it does not occupy space of drilling well or occupies less space of drilling well.
Description
Technical field:
The utility model relates to the quick grouting device of multiple spot between a kind of freeze-wellboring wall.
Background technology:
Freeze-wellboring adopts concrete or the reinforced concrete double borehole wall, plastic sandwich composite shaft lining structure more, behind inside and outside layer borehole wall casting complete, also must carry out slip casting between wall, connect the outer wall crack that stubble stitches, pressure of freezing wall produces with gap, the outer shaft wall construction that exists between filling plastic plate and the outer wall, prevent that the borehole wall from leaking.
The grouting device that slip casting is used between wall is made up of Grouting Pipe, defeated slurry sebific duct at present.Grouting Pipe level punching on the internal layer borehole wall is installed or lays pre-buried, and between Grouting Pipe one end connecting wall, the other end connects defeated slurry sebific duct, and defeated slurry sebific duct connects grouting pump on the hanging scaffold.Existing grouting device can be finished slip casting between wall, but owing to only be suitable for slip casting on hanging scaffold, once only connect a Grouting Pipe, belong to single-point slip casting, the slurries range of scatter is little, between the complete dark wall of such freezing shaft tens Grouting Pipe need be set one by one, and carry out slip casting one by one, shutoff one by one after the slip casting, injection speed is slow, efficient is low, take that shaft construction is long in time limit, aided process is many, expense is high.
The utility model content:
The purpose of this utility model provides that a kind of speed is fast, efficient is high, do not account for or account for less pit shaft, can not only be on ground also can be between the freeze-wellboring wall that the pit shaft hanging scaffold is implemented the quick grouting device of multiple spot.
To achieve these goals, the utility model comprises: Grouting Pipe, slurry casting machine, the slip casting person in charge, feed pipe for mortar, defeated slurry sebific duct, on being responsible for, slip casting evenly is provided with a row slurry casting machine, slurry casting machine is connected with Grouting Pipe, the upper end that slip casting is responsible for is connected with feed pipe for mortar, and the upper end of feed pipe for mortar is connected with defeated slurry sebific duct.Like this, when implementing to carry out slip casting between wall, to fail the slurry sebific duct and be connected to grouting pump, slurries will be responsible for by feed pipe for mortar, slip casting and arrive each slurry casting machine and each Grouting Pipe simultaneously, a plurality of Grouting Pipe are formed multiple spot slip casting, slurries diffuse to form a slip casting band, have simple in structure, easy for installation, injection speed is fast, efficient is high, do not account for or account for less characteristics such as pit shaft, remarkable benefit.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that slurry casting machine, Grouting Pipe connect cross-sectional view.
The specific embodiment:
As seen from Figure 1, Figure 2, the utility model comprises: Grouting Pipe 2, slurry casting machine 3, slip casting are responsible for 4, feed pipe for mortar 7, defeated slurry sebific duct 8.The height that slip casting is responsible for is equivalent to a slip casting section height, be generally 100-200m, on the slip casting person in charge 4, evenly be provided with a row slurry casting machine 3, slurry casting machine 3 adopts the screw thread mode to be connected with Grouting Pipe 2, slurry casting machine is the reducer tee structure communicates the Grouting Pipe 2 and the slip casting person in charge 4, on slip casting mouth of pipe wall, have four semicircles and penetrate slurry hole 9, slurries are convenient to scattering all around.On the slip casting tube head, be provided with a umbrella ring baffle 1, prevent that the slip casting mouth of pipe from stopping up.Grouting Pipe, slurry casting machine, slip casting are responsible in the construction of the internal layer borehole wall default, pre-buried, communicate between the slip casting mouth of pipe and wall, and each Grouting Pipe becomes a slip casting point, and a plurality of Grouting Pipe are formed a plurality of slip casting points.Slip casting is responsible for 4 upper ends and is bent from the borehole wall and be connected with feed pipe for mortar, is serially connected with pressure regulator valve 5 and control valve 6 on feed pipe for mortar, and pressure regulator valve can be controlled grouting pressure, and control valve can be regulated defeated slurry amount.The upper end of feed pipe for mortar 7 is connected with defeated slurry sebific duct 8, and defeated slurry sebific duct can be connected on the grouting pump.The utility model can be connected well head surface grout injection pump, the quick slip casting of a multiple spot of facing the wall and meditating with implementing well head; Also can be connected pit shaft hanging scaffold grouting pump and carry out the quick slip casting of multiple spot between wall.
