Abstract
The utility model discloses a broken rock advance curtain grouting double-channel sectional grouting device which comprises a grouting pipeline and a cerement paste pipeline, wherein the cerement paste pipeline is sleeved in the grouting pipeline, the grouting pipeline and the cerement paste pipeline are completely separated, and the orifice of the cerement paste pipeline penetrates out of the orifice of the grouting pipeline. The grouting device has the advantages that as the grouting pipeline and the cerement paste pipeline are separately arranged, the grouting pipeline and the cerement paste pipeline can grout two kinds of liquid for rocks nearby a working face to fix, and the grouting holes on front portion can be not blocked, thereby continuing to grout for forming a water curtain after the rocks nearby the working face are solidified, and realizing the sectional grouting.
Description
Technical field
The utility model relates to a kind of constructing tunnel equipment, especially relates to a kind of construction of tunnel mortar depositing construction equipment.
Background technology
In underground construction ejection for water plugging work progress, run into face rock crushing and percolating water than serious situation, normally biliquid slurry blender carries out pressure injection rapid hardening slurries (biliquid slurry) and carries out fixed to the peripheral certain thickness country rock of face and percolating water is carried out shutoff.The structure of biliquid slurry blender as shown in Figure 2, comprise: cement paste inlet 21 that sets up separately and water glass inlet 22, cement paste and water glass enter the back to be mixed in biliquid slurry mixing tube 25, be connected with stop grouting plug or orifice tube 24 in biliquid slurry mixing tube 25 the place aheads by the connecting filament mouth, the pipeline between cement paste inlet 21, water glass inlet 22 and biliquid slurry mixing tube 25 is provided with one way valve 23.This blender can realize that slurries mix, and solidifies in mobile and diffusion process behind the slurry filling, reinforces country rock and the phreatic purpose of shutoff thereby play.
According to construction experience, the cycle of leading curtain-grouting is long, does not have good situation of ending the magmatic rock dish if run into rock crusher, also need to satisfy good slip casting effect by building wall for grouting, so the curtain-grouting cycle period is longer, and construction speed is slower; If do not build wall for grouting, then need to adopt biliquid slurry (realizing) nearly face country rock is reinforced and face percolating water to be carried out shutoff handle by common biliquid slurry blender, so that what form leading curtain-grouting ends the magmatic rock dish certainly, after only the magmatic rock dish forms, execute to front of tunnel heading again and bore pre-grouting boring, carry out the curtain-grouting construction.So promptly increased workload, also made broken originally nearly face rock mass influence the stagnant water effect of rock mass self, ended the magmatic rock dish thereby be difficult to utilize country rock and biliquid slurry to form because of the boring of repeatedly holing disturbance and gather.
The utility model content
The utility model has overcome the shortcoming in the present technology, the leading curtain-grouting binary channels of a kind of fragmented rock body segmenting slip casting device is provided, solved in seabed tunnel breaking surrounding rock infiltration location under the situation of no wall for grouting (ending the magmatic rock dish), according to different size performances and slip casting requirement, do not repeat boring, emptying under the condition, realizing the technical barrier of segmented slip casting.
The technical solution of the utility model is: the leading curtain-grouting binary channels of a kind of fragmented rock body segmenting slip casting device, comprise grouting pipe and cement paste pipeline, cover cement paste pipeline in the described grouting pipe, grouting pipe and cement paste pipeline separate fully, and the mouth of pipe of cement paste pipeline stretches out outside the mouth of pipe of grouting pipe.
The front end that inserts the water glass pipeline in described grouting pipe side direction is provided with the pressure relief opening of being with valve.
On the pipeline between described grouting pipe and the water glass inlet, one way valve is set.
The outer length of the mouth of pipe that the mouth of pipe of described cement paste pipeline stretches out grouting pipe is 3 to 6 meters.
Compared with prior art, the utility model has the advantages that: because the branch of grouting pipe, cement paste pipeline is arranged, two kinds of liquid slurries of pressure injection carry out fixed to nearly face rock mass simultaneously, can not stop up anterior injected hole again, thereby reach after nearly face rock mass is reinforced rapidly, continue reperfusion serosity again and form the purpose of water-stop curtain, thereby realize segmenting slip casting.Be embodied in:
1. can satisfy the different passages that utilize slurry casting machine by same hole, according to the country rock situation, different slurries are poured in segmentation.Broken and have under the percolating water situation at face, face certain thickness laccolite perfusion biliquid slurry is formed end the magmatic rock dish earlier, guarantee that simultaneously the duct do not stop up, be used further to the secondary curtain-grouting;
2. utilize this slurry casting machine, can not build wall for grouting or, reduce the further destruction of boring fragmented rock body separately for reinforcing the face slip casting of holing;
3. can improve the speed and the effect of the leading sealing slip casting of fragmented rock body, and can adjust grouting process at any time, the uneven rock mass of degree of crushing is embodied superiority flexibly according to country rock situation and slip casting situation.
4. can be according to fragmented rock body degree of crushing and face percolating water degree, take the method for spreading (getting final product) stop grouting plug and lengthening hollow core barrel by welding common φ 42 steel pipe spreadings, adjust the degree of depth that the biliquid slurry is reinforced fragmented rock body, to satisfy the needs of shutoff under the different geological conditionss.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of existing biliquid slurry blender.
The specific embodiment
Disclosed all features in this manual, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this manual (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, the leading curtain-grouting binary channels of a kind of fragmented rock body segmenting slip casting device comprises: the pressure relief opening 7 of cement paste inlet 1, hollow tube connector 3, cement paste pipeline 6, band valve, water glass inlet 9, one way valve 10, grouting pipe 11.
Grouting pipe 11 is connected with stop grouting plug 5 by stop grouting plug connector 4, on the pipeline between grouting pipe 11 and the water glass inlet 9 one way valve 10 is set, and the front end that inserts the water glass pipeline in grouting pipe 11 side direction is provided with the pressure relief opening 7 of being with valve; Be with cement paste pipeline 6 in the grouting pipe 11, cement paste pipeline 6 is connected with cement paste inlet 1 by hollow tube connector 3, and the mouth of pipe of cement paste pipeline 6 stretches out outside the mouth of pipe of grouting pipe 11.
