Abstract
The utility model discloses a grouting anchor pipe combination comprising a grouting core pipe and a plug of the grouting core pipe end. The other end of the grouting core pipe is provided with a nipple, and the middle of the grouting core pipe is provided with a grouting outlet hole, wherein the outside of the tube of grouting outlet hole is provided with an one directional stop grouting casing which is a semi-closed casing. On the grouting core pipe, a plurality of stents is jacketed, and the stent is provided with a plurality of glass fibre anchors. In the grouting reinforcement process of underground engineering, the utility model has the characteristics of grouting, anchorage, corrosion resistance, large tensile strength, small shear force, excavation and low weight.
Description
Technical field
The utility model relates to a kind of anchor tube, and it is mainly used in a kind of combination grouting anchor pile of constructing tunnel, stratum consolidation, excavation of foundation pit supporting and slope soil anchoring.
Background technology
The New Austrian Tunneling Method bolt-spary supports is a support form commonly used in the current engineering circle constructing tunnel, wherein anchor tube is main supporting equipment, and the maximum of usefulness are sleeve valve formula slip casting core pipes, it is a steel material, sleeve valve formula slip casting core pipe only can carry out grouting and reinforcing to the stratum when using in the underground construction operation, in tunnel or Underground Engineering Excavation process, can not form anchoring effect to the stratum, and its steel material very easily be subjected to corrosion failure and produce dangerous, its shearing force is big in addition, tensile strength is low, poor durability, weight is big.
The utility model content
The purpose of this utility model is to provide a kind of combination grouting anchor pile, and it is corrosion-resistant in the underground construction operation, tensile strength is big, and shearing force is little, and is durable and in light weight.
To achieve these goals, technical solution of the present utility model is: a kind of combination grouting anchor pile, comprise slip casting core pipe and pipe end plug thereof, the slip casting core pipe other end is provided with nipple, slip casting core pipe middle part is provided with slurry outlet, and wherein said slurry outlet pipe is provided with the unidirectional slurry cover that ends outward, and the unidirectional slurry cover that ends is semi-closed casing, on slip casting core pipe, be with several supports, several reinforced plastic glass fibre anchor sheets are installed on described support.
A kind of combination grouting anchor pile of the utility model, wherein said unidirectional only slurry cover middle part is a pipe, two ends are the Taper Pipe shape.
A kind of combination grouting anchor pile of the utility model, wherein said support are two i.e. first support and second supports, and it is a rigid plastics, and two reinforced plastic glass fibre anchor sheets are installed in the two stands left and right sides.
A kind of combination grouting anchor pile of the utility model, wherein outside first support and second support respectively by the fastening of iron sheet hoop.
A kind of combination grouting anchor pile of the utility model, wherein said reinforced plastic glass fibre anchor sheet are geminal fibers sheet or three fibre plates or four fibre plates formation.
After adopting such scheme, the utility model can be realized following function:
1. safety is good, it can antistatic, fire-retardant, satisfy the requirement that underground engineering safety is produced;
2. shearing force Xiao Yi abolishes, after face adopts pre-reinforcing of glass fiber anchor chip anchor tube in the construction of tunnel, the shield machine tool, mill excavation mechineries such as digging machine, TBM, single boom roadheader can wipe out smoothly by, do not damage cutter, can realize that the mechanization in tunnel is efficiently constructed;
3. tensile strength height can reach 1.5～2.0 times of steel anchor pole;
4. good endurance, highly corrosion, acidproof, alkaline-resisting, high temperature resistant, low temperature resistant;
5. weight is 1/4～1/5 of specification steel anchor pole of the same race, greatly reduces the fitting operation working strength of workers, has improved operating efficiency.

Fig. 2 is a kind of combination grouting anchor pile of the utility model A-A generalized section;
Fig. 3 is a kind of three-dimensional generalized section that makes up grouting anchor pile of the utility model.
The specific embodiment
See also Fig. 1, shown in Figure 2, a kind of combination grouting anchor pile of the utility model comprises slip casting core pipe 1 and pipe front end plug 2 thereof, slip casting core pipe 1 other end is provided with nipple 11, slip casting core pipe middle part is provided with slurry outlet 12, be provided with the unidirectional slurry cover 3 that ends outside slurry outlet 12 pipes, unidirectional only slurry cover 3 is a semi-closed casing, its middle part is a pipe, two ends are the Taper Pipe shape, vertically offer a seam 31 at the unidirectional slurry pipe that ends, as shown in Figure 2, before slip casting core pipe 1, the rear portion is with first plastic stent 41 and second plastic stent 42 respectively, in the engaging of the left and right sides of first plastic stent 41 and second plastic stent 42 two reinforced plastic glass fibre anchor sheets 51 are arranged, 52, reinforced plastic glass fibre anchor sheet 51,52 are geminal fibers sheet formation, fastening outside first plastic stent 41 has an iron sheet hoop 61, and fastening outside second plastic stent 42 has an iron sheet hoop 62, effectively with reinforced plastic glass fibre anchor sheet 51,52 combine with slip casting core pipe 1.
During use, as shown in Figure 3, a grouting pump is installed at nipple 11 places at slip casting core pipe 1, grouting pump pours into slurries in the slip casting core pipe 1, because slip casting core pipe 1 middle part offers slurry outlet 12, therefore slurries flow out in the unidirectional only slurry cover 3 that enters its outside from slurry outlet 12, because the unidirectional slurry cover 3 that ends is offered a seam 31, after reaching certain pressure in the slip casting core pipe 1, slurries from unidirectional seam 31 extrudate flows of slurry cover that end at reinforced plastic glass fibre anchor sheet 51, on 52, slurries diffuse in the certain radius scope around slip casting core pipe 1, after slurries solidify, reinforced plastic glass fibre anchor sheet 51,52 and strengthening stratum between form bond stress, thereby in the underground engineering construction process, effectively the high characteristic of performance reinforced plastic glass fibre anchor sheet tensile strength reaches the grouting and reinforcing stratum, the anchoring effect on glass anchoring stratum.
All any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all be included in the utility model scope.
