Description
Technical field
The utility model belongs to the tunnel and underground construction weak surrounding rock pre-grouting is reinforced and water-plugging technique, mainly proposes a kind of ductule segmentation repeatedly slip-casting device.
Background technology
In weak water bearing ground, carry out tunnel and underground engineering construction, the problem of easy appearance is the country rock large deformation and caves in and excavate face water burst, prominent mud, jeopardize personnel, device security, cause casualty accident, cause that the face of land caves in when serious, vegetation deterioration influences resident's normal life, and ground environment is damaged.In order to guarantee construction safety, stratum consolidation and shutoff method commonly used both at home and abroad at present are slip casting method, slip casting method is exactly by certain pressure a certain amount of gelling material to be injected the rock stratum or the soil body, make that it flows in formation fractures or soil body space, diffusion, filling, fixed, be formed with the adhesive bond of certain intensity and low permeability, strengthening stratum, shutoff underground water, thereby improve the self-stabilization time of country rock, for applying of supporting and protection structure creates conditions.The grouting with small pipe method is one of main method wherein.But present grouting with small pipe method adopts the disposable slip casting in full hole usually, can't carry out the segmentation repeatedly slip-casting as required; The ductule that is adopted is a spray of molten steel tubular structure, and in the process of heading into, silt particle enters steel pipe along the eyelet on the pipe easily, and cramming causes slip casting effect bad or annotate and not advance slurry.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of ductule segmentation repeatedly slip-casting device, makes it can satisfy the needs of segmentation repeatedly slip-casting.
The utility model is finished the technical scheme that its invention task taked: it mainly is made of grouting pump, inlet pipe and ductule, slip casting core pipe, wherein the ductule front end is cone-shaped structure and sealing, in the spaced apart a plurality of excessive slurries hole that is equipped with of its tube wall upper edge tube axis direction, be nested with the slurry hole sealing of will overflowing of ring-shaped rubber cover at the place, slurry hole of overflowing, rubber sleeve is positioned at the circumferential groove that sets on the ductule outer wall; Slip casting core pipe is positioned at its front end of ductule and also is enclosed construction, on the tube wall of slip casting core pipe leading portion, have a plurality of slurry outlets along the pipe circle distribution, before and after slurry outlet, be equipped with a plurality of annular stop grouting plugs on the tube wall of both sides, stop grouting plug is a leather cup formula structure, be positioned at its rim of a bowl direction of stop grouting plug on the tube wall towards slurry outlet, slip casting core pipe rear end is communicated with grouting pump by inlet pipe.
The utility model slip casting course of work: adopt air drill boring to designing hole depth, withdraw from drilling rod, with ductule pack into boring in, with accelerated cement the space between mouth of pipe outer wall and the boring inwall is sealed, the slip casting core pipe that will have leather cup formula stop grouting plug enters in the ductule to design attitude, slip casting core pipe rear end and inlet pipe, grouting pump connection carrying out slip casting, slurries overflow from the slurry outlet of slip casting core pipe leading portion, enter between ductule and the slip casting core pipe, be positioned at the stop grouting plug expanse of both sides, slurry outlet front and back under pressure, hold out against the ductule inwall, to seal between ductule and the slip casting core tube wall, slurries are washed the rubber stopper on the excessive slurry of the ductule hole open, enter the stratum by spout hole and finish this section slip casting; After stopping slip casting, receive reinstatement in the pressure release of leather cup formula stop grouting plug; Pull back slip casting core pipe to next section slip casting position, carry out slip casting, retreat segmenting slip casting so repeatedly and finish, withdraw from slip casting core pipe and carry out next hole mortar depositing construction up to this hole slip casting.The segmentation repeatedly slip-casting makes the slurries diffusion ratio more even, and grouting quality is guaranteed easily.And can be according to the stratum deformation situation, repeated multiple times is reinforced the stratum, obtains better slip casting effect.
The medium and small supravasal rubber sleeve of the utility model device can use repeatedly, in the slip casting process, wash the rubber sleeve that is stuck on the slurry hole of overflowing open and carry out slip casting when pressure acquires a certain degree, when grouting pressure reduces, can close the slurry hole of overflowing by the elasticity of rubber sleeve, thereby in the repeatedly slip-casting construction, reach good sealing effectiveness; The structure design of slip casting core pipe can satisfy the needs that retreat segmentation and repeatedly slip-casting.
