Abstract
The invention discloses a weak stratum tunnel advanced deep-hole grouting reinforcement material. The material comprises the following raw materials by weight percentage: 50% of clinker, 3.8% of limestone, 4% of ore powder, 5.5% of desulfurized gypsum, 0.7% of calcium oxide, 0.6% of silica-gel powder, 4% of glass bead, 11% of zeolite, 3% of cellulose ether, 5% of a concrete expanding agent, 0.7% of polypropylene fiber, 0.7% of steel fiber, 1% of an accelerator and 10% of water. The material has the advantages that while in use, the material is pressed in a hole grouting zone by high pressure, the grouting material is rapidly solidified, the material forming a paste body has the advantages of good fluidity and groutability, is easily grouted into a tunnel surrounding rocks stratum, gelation time is adjustable, stability is good, water permeability of a solidified body is very low, tunnel surrounding rocks can be solidified, and stability of the tunnel surrounding rocks can be enhanced.
Description
Technical field
The present invention relates to a kind of hole slip casting strengthening material, in particular, relate to a kind of soft stratum tunnel advanced deep hole grouting reinforcement material.
Background technology
At present, soft stratum tunnel excavation construction Lead grouting strengthening technique has multiple means, as: the technology such as per-fore pouring liquid with small pipe, grouting, Shed-pipe Advanced Support slip casting, horizontal sleeve valve barrel grouting.Injecting paste material is various informative, as: modified water glass slurry, the single slurry of Portland cement, cement-other injecting paste material such as water glass dual slurry, superfine cement slurry.
Carbon fibre tube pre-grouting is reinforced compared with per-fore pouring liquid with small pipe, grouting, horizontal jet grouting injection technology, have that disposable effective strengthening length is dark, reinforcing scope is large, strengthening quality reliably, face stabilizer more easy to control and ground settlement feature; Novel superpower injecting paste material, compared with above-mentioned injecting paste material, has early epistasis, weather resistance, micro-expansibility, water-repellancy, the feature such as comprehensive, can accelerating construction progress, working face dry cleansing civilized construction.
Grouting hole adds has ductile strength height carbon fibre tube, has both improved slip casting bulk strength, ensures construction quality and safety, compared with advanced tubule, tube shed grouting, substitute in grouting hole again and add anchor pole or reinforcing bar, steel pipe, save steel, reach the object reducing construction cost and economize on resources.
Tunnel Water Leakage is durable and stable to tunnel structure, facility, traffic safety, ground buildings or structures and groundwater environment produce many detrimentally affects in hole, and percolating water impels concrete lining weathering, degrades, and causes liner structure to destroy; Percolating water also can soften country rock, causes surrouding rock deformation, causes tunnel load to increase; Containing corrosive medium in some water seepage of tunnel, cause general lining concrete and masonry mortar corrosion damage, reduce the supporting capacity of lining cutting; At Han Qu, tunnel leak can cause abutment wall to freeze, and invades clearance of tunnel, also can cause lining cutting frost heave rhegma, percolating water accelerates internal unit (communication, illumination, track etc.) corrosion, affects the normal use of equipment, shorten the work-ing life of line facility, increase maintenance cost; Water damage causes subgrade settlement, substrate rhegma, the disease such as to rise soil, and causes rail track gauge horizontal distortion to transfinite, and it is uneven that frost heave causes circuit in hole, and leaks in hole and moistly reduce adhesive force of wheel track, all can have a strong impact on traffic safety; Water damage makes electrical isolation inefficacy, short circuit, tripping operation, affects safe operation, causes electric leakage casualty accident.
At present, domestic and international Tunnel Water Leakage grouting for water-blocking material is slurries, slip casting effect is general, and weather resistance is not good, for this reason development one can be contained water seepage of tunnel effectively, durability degree is good, by force handling, and can not to environment produce pollute Tunnel Water Leakage grouting for water-blocking material be necessary.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and provide that a kind of slip casting effect is good, durability degree is good and can not produce environment and pollute, improve operating efficiency, reduce a kind of soft stratum tunnel advanced deep hole grouting reinforcement material of construction cost.
