Description
Technical field
The utility model relates to two fluid grouting applied technical field, especially a kind of retrusive two-liquid grouting device.
Background technology
In mortar depositing construction, completely decomposed granite easily meets water softening disintegration, even trickle, cause boring collapse hole, pore-forming difficulty, cause adopting normal protrusive segmenting slip casting technique hole-bottom slurry-injection effect bad, between rock particles, adhesion completely loses, and rock mass is in gravel matter lam or chiltern lam shape, porosity is comparatively large, water stability is poor, very unfavorable to underground engineering construction.Construct in this stratum, trickle to prevent excavation face and cave in, the measure of slip casting will be taked, conventional grouting method adopts protrusive segmenting slip casting technique, due to this technique hole-drilling repeatedly slip-casting repeatedly, more loaded down with trivial details, simultaneously in completely decomposed granite because Completion of Drilling Hole is more difficult, cause hole-bottom slurry-injection effect bad, and single tube drilling rod slip casting method is exactly directly utilize the drilling rod of drill hole of drilling machine as the method for Grouting Pipe from the slip casting of drilling rod front end, reduce efficiency of construction, increase difficulty of construction, especially good construction effect can not be obtained in vertical slip casting, therefore, for the problems referred to above, we propose a kind of retrusive two-liquid grouting device.
Prior art can not meet the needs of people, for making up prior art deficiency, it is simple that the utility model aims to provide a kind of process implementing, conveniently regulates gel time, effective minimizing water is to the change of slurries gelatinization performance, calculus rate is high, has micro-expansibility, excellent in durability, avoid a large amount of splittings, extruding situation, can uniform consolidation layer of sand preferably, form complete water protecting curtain, be beneficial to the retrusive two-liquid grouting device of progress monitoring.
For achieving the above object, the utility model by the following technical solutions: a kind of retrusive two-liquid grouting device, at least comprises rubber grout stop, boring, stop grouting plug, clay, plasma discharge mouth, Grouting Pipe and slip casting core pipe; Described Grouting Pipe to be arranged on inside clay and compact siro spinning technology; Described clay is arranged on two-liquid grouting device periphery and parcel two-liquid grouting device; Described boring is evenly arranged on clay inside; Described plasma discharge mouth interts Grouting Pipe and clay and exceed clay external surface; Described rubber grout stop is closely nested in Grouting Pipe; Described slip casting core pipe is arranged on inside Grouting Pipe; Described stop grouting plug is arranged on grouting core pipe, and closely nested with grouting core pipe.
As optimisation technique scheme of the present utility model: described plasma discharge mouth is made up of slip casting core pipe plasma discharge mouth and Grouting Pipe plasma discharge mouth, respectively to Grouting Pipe and the plasma discharge of slip casting core pipe; Described stop grouting plug is nested on grouting core pipe, avoids slurries to backflow.
Compared with prior art, the beneficial effects of the utility model are: this device adopts two fluid grouting, and by admixture retarding agent, can regulate gel time easily, can reduce the change of water to slurries gelatinization performance, calculus rate is high in addition, there is micro-expansibility, excellent in durability.Biliquid instillation process is implemented easily, can uniformly penetrating diffusion in middle fine sand layer, and a large amount of splittings, extruding situation not easily occur, can uniform consolidation layer of sand preferably, forms complete water protecting curtain.The safety into hole is excavated smoothly with next step to adopt the method for two fluid grouting ensure that, ensure that the duration on the whole, be conducive to progress monitoring, in addition in boring, mortar depositing construction, take by two ends to middle, boring from down to up, grouting sequence, thus the actual geological condition being judged stratum by boring, to reduce unnecessary workload, form sequence of construction from the easier to the more advanced, final boring, slip casting smooth, be applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of retrusive two-liquid grouting device, at least comprises rubber grout stop 1, boring 2, stop grouting plug 3, clay 4, plasma discharge mouth 5, Grouting Pipe 6 and slip casting core pipe 7; Described Grouting Pipe 6 to be arranged on inside clay 4 and compact siro spinning technology; Described clay 4 is arranged on two-liquid grouting device periphery and parcel two-liquid grouting device; It is inner that described boring 2 is evenly arranged on clay 4; Described plasma discharge mouth 5 interts Grouting Pipe 6 and clay and exceed clay 4 external surface; Described rubber grout stop 1 is closely nested in Grouting Pipe 6; Described slip casting core pipe 7 is arranged on inside Grouting Pipe 6; Described stop grouting plug 3 is arranged on grouting core pipe 7, and closely nested with grouting core pipe 7.
As optimisation technique scheme of the present utility model: described plasma discharge mouth 5 is made up of slip casting core pipe plasma discharge mouth and Grouting Pipe plasma discharge mouth, respectively to Grouting Pipe 6 and the plasma discharge of slip casting core pipe 7; Described stop grouting plug 3 is nested on grouting core pipe 7, avoids slurries to backflow.
As preparation of construction of the present utility model: the thing that we consider in the process of grouting design has: grouting and reinforcing scope; Slip casting segment length, grouting and reinforcing scope, grouting dike thickness, grout spreading range, injection speed, slurries gel time, in addition, in the process of slip casting, in order to prevent work plane grout in mortar depositing construction process, we carry out thickness of shotcrete to work plane and are not less than 15cm and close, and steel pipe adds backing plate and nut; Before mortar depositing construction, notice that plant keeps in repair, the machineries such as rig, grouting pump, mixer are checked, keep in repair, maintained, makes it maintain good state; In process for preparation, except performing on-the-spot work, also must make an effort from source, this engineering adopts water/binder ratio to be the cement paste of 1: 1, first according to the volume of preformulation cement paste, the consumption of required superfine cement, water and retarding agent is calculated by water/binder ratio and retarding agent volume, then according to consumption, add water and retarding agent in a reservoir, strong stirring, after retarding agent fully dissolves by the time, add superfine cement again, uniform mixing, after preparation and material formulation have been got well, just can construct.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
