Abstract
The utility model discloses a kind of deep covering layer two-shot grouting plug, comprising: cement grout grout pipe, as the passage of cement injection slurries; Be positioned at the water glass grout pipe of cement grout grout pipe inside, as the passage of priming petock glass; Wherein, the length of water glass grout pipe is longer than the length of cement grout grout pipe.The utility model reduces grouting amount and slurries treat the solidifying time, completing smoothly of Guarantee item.
Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering field, particularly relates to a kind of deep covering layer two-shot grouting plug.
Background technology
During deep covering layer grouting stratomere as king-sized in wastage, even if the paste serous material of the denseest one-level of perfusion also has no idea to fill with, there is following problem: make work progress fill with number of times again too much, grout consumption is large, loses time and cost; Make slurries long for time of setting, can not normal termination, affect construction speed.
Utility model content
The purpose of this utility model is exactly to overcome above-mentioned prior art Problems existing, provides a kind of deep covering layer two-shot grouting plug, and minimizing grouting amount and slurries treat the solidifying time, completing smoothly of Guarantee item.
In order to realize above-mentioned purpose of the present utility model, provide following technical scheme:
A kind of deep covering layer two-shot grouting plug, comprising: cement grout grout pipe, as the passage of cement injection slurries; Be positioned at the water glass grout pipe of cement grout grout pipe inside, as the passage of priming petock glass; Wherein, the length of water glass grout pipe is longer than the length of cement grout grout pipe.
Preferably, the hypomere of described water glass grout pipe stretches out cement grout grout pipe 5 ~ 10m.
Preferably, the hypomere of described water glass grout pipe is pvc pipe.
Preferably, described water glass and cement grout adopt biliquid pump or proportioning pump perfusion, to ensure that the injection pressure of water glass and cement grout is consistent.
Preferably, described pvc pipe is connected with water glass grout gas thread.
Preferably, being also provided with outside described cement grout grout pipe can the expansion jam of harmomegathus, and during for expanding, jam is at sleeving valve pipe assembly inwall.
The beneficial effects of the utility model embody in the following areas:
1, the utility model uses cement grout and water glass grout, and effectively control the diffusion of cement grout at wastage layer significantly, obvious minimizing fills with number of times again, and slurries treat that the solidifying time also reduces, and improves construction speed;
2, water glass grout pipe extends by the utility model, makes water glass away from bottom packer, thus away from the direct cement grout flowed out bottom packer, cement grout can not be condensed near packer, reduces the probability of casting plug;
3, the utility model is by adjustment cement grout and the grouting time of water glass, guaranteeing that cement grout can not the just rapid hardening when flowing out packer, preventing casting plug, guaranteeing construction speed.
Accompanying drawing explanation
Fig. 1 is the structural representation of two-shot grouting plug of the present utility model.
Description of reference numerals: 7-cement grout grout pipe; 71-expansion jam; 8-water glass grout pipe; 81-PVC manages.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of deep covering layer two-shot grouting plug, comprising: cement grout grout pipe 1, for the perfusion channel of cement grout; Be positioned at the water glass grout pipe 2 of cement grout grout pipe 1 inside, for the perfusion channel of water glass; Be positioned at the expansion jam 71 outside cement grout grout pipe 1, during for installing two-shot grouting plug in sleeving valve pipe assembly, jam is at sleeving valve pipe assembly inwall; Wherein, the length of water glass grout pipe 2 is longer than the length of cement grout grout pipe 1, makes biliquid remain at a segment distance mixing of below packer, avoids casting plug.
Concrete operation step of the present utility model is:
First, connect pipe-line system, by expansion jam 71 jam on sleeving valve pipe assembly inwall, slurry liquid of then fetching boiling water grout pipe 1, cement injection slurries 200 ~ 300L in cement grout grout pipe 1; Then, glass grout pipe 2 of fetching boiling water, priming petock glass in water glass grout pipe 2, the pressure of priming petock glass will be consistent with the pressure of cement injection slurries; Wherein, Continuous Perfusion cement grout and water glass certain hour under the state that the injection pressure of water glass and cement grout is consistent, in filling process, when cement grout and water glass flow diminish, and pressure raise very fast time, close water glass grout pipe 2, cement grout continues perfusion 100-200L, terminates grouting.
The incipient stage of perfusion, the grouting pressure of cement grout and water glass is 0.2 ~ 0.3MPa, when needs increase injection pressure, and must the synchronous grouting pressure increasing cement grout and water glass.
Preferably, total perfusion volume ratio of the utility model cement grout and water glass is 1:1.
The utility model adopts first cement injection slurries on the one hand, the method of priming petock glass and then, the cement grout when priming petock glass is made to have deposited slurry seldom, can not on gush, the hypomere of water glass grout pipe 2 is made to stretch out cement grout grout pipe 5 ~ 9m on the other hand, make water glass as far as possible away from bottom packer, make biliquid mix the safety area remaining at below packer, be unlikely to threaten packer and cast plug.
The utility model adopts biliquid pump or proportioning pump priming petock glass and cement grout, to ensure that the injection pressure of water glass and cement grout is consistent.
The hypomere of water glass grout pipe 1 of the present utility model is pvc pipe, scraps rear replacing conveniently.
Although above-mentioned, the utility model is elaborated; but the utility model is not limited thereto; those skilled in the art can modify according to principle of the present utility model; therefore, all various amendments carried out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
