Abstract
A grouting anchor rope comprises a steel stranded wire, a support disc, an arch-shaped hole grouting cushion disc and a lock. The support disc, the arch-shaped hole grouting cushion disc and the lock are sequentially arranged on the steel stranded wire, a grouting flexible tube is wrapped on the outer surface of the steel stranded wire, an arch-shaped hole is arranged on a tube wall of the tubular arch-shaped hole grouting cushion disc, a hole bottom fixing ring is arranged on one side of one end, closely attached to the steel stranded wire, of the grouting flexible tube and used for fixing the grouting flexible tube onto the steel stranded wire, and the other end of the grouting flexible tube is led out from the arch-shaped hole of the arch-shaped hole grouting cushion disc. The grouting anchor rope uses the grouting flexible tube as a grouting passage, the high-strength steel stranded wire as a supporting and protecting device and integration of anchor rope reinforcement and grouting reinforcement, not only realizes full-field anchoring of the anchor rope, but also realizes strengthening of surrounding ground grouting, and avoids additional arrangement of grouting devices, thereby quickening tunnel construction, lowering supporting and protecting cost, and simultaneously being capable of effectively guaranteeing tunnel stability. The grouting anchor rope has the advantages of simple structure, low cost, reliable performance, simple, convenient and speedy construction and excellent protection performance for tunnels.
Description
Technical field
The utility model relates to a kind of grouting cable anchor, especially a kind of grouting cable anchor that is applicable to heavily stressed breaking surrounding rock and dead-soft rock strata support in ore deposit, tunnel, the underground construction.
Background technology
Along with constantly development of coal in China industry, many mining areas all run into increasing weak broken rock stratum, and this rock stratum has characteristics such as expansion, rheology, and degree of consolidation is poor, and this makes that soft-rock tunnel is the difficult point of supporting always.
In recent years, in order to reduce support cost, China on the basis of adopting the weak roadway surrounding rock of metal scalability bracket support, the various types of bolt supports of test of many times once.Yet the loose range of country rock of soft rock roadway is bigger, and rock mass strength is low, can't provide stable origin of force for anchor pole.Therefore, use cable bolting to be difficult to make broken sillar to be in pressured state fully and to form built-up arch merely.All, at present a lot of mines adopt the method for the preceding slip casting of supporting, make broken rock mass become as a whole, and then carry out supporting.Yet first slip casting makes broken rock mass become as a whole, and then more loaded down with trivial details with the method for cable bolting, and the two can not carry out simultaneously.So just cause perforating many, problems such as construction complexity.Though existing several grouting cable anchors on the market, complex structure, the support strength of the anchor cable that has is lower.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, and anchor cable and slip casting are integrated, conveniently grouting cable anchor.
For achieving the above object, grouting cable anchor of the present utility model comprises steel strand, is located at pallet, arch hole slip casting disc, lockset on the steel strand successively, and the external surface of steel strand is enclosed with the slip casting flexible pipe, described arch hole slip casting disc is cylindric, and its barrel has an arch hole; The side that slip casting flexible pipe one end is close to steel strand is provided with retainer ring at the bottom of the hole that is fixed on the steel strand, and the other end of slip casting flexible pipe is derived by the arch hole of arch hole slip casting disc; Described slip casting flexible pipe is made by the belt flexible pipe.
Beneficial effect: as the slip casting device, high strength steel strand is as the supporting device with the slip casting flexible pipe for the utility model.According to the needs grouting and reinforcing of engineering, the anchored force of anchor cable and the globality of country rock have been increased, for cable bolting provides reliable origin of force.Accelerate the soft-rock tunnel construction, reduced support cost, can effectively guarantee the stability in tunnel simultaneously.It is simple in structure, and cost is low, dependable performance, and easy construction is quick, and is strong to the protective value in tunnel, has practicality widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cross section structure figure of Fig. 1.
Fig. 3 is the B partial enlarged drawing among Fig. 1.
Among the figure: steel strand-1; Lockset-2; Slip casting disc-3; Arch hole-3-1; Slip casting flexible pipe-4; Retainer ring at the bottom of the hole-5; Pallet-6.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Grouting cable anchor of the present utility model mainly is made of retainer ring 5, pallet 6 at the bottom of steel strand 1, lockset 2, arch hole slip casting disc 3, slip casting flexible pipe 4, the hole, and arch hole slip casting disc 3 is cylindric, and its barrel has an arch hole 3-1; The slip casting flexible pipe of being made by the belt flexible pipe 4 is wrapped in the external surface of steel strand 1, the side that slip casting flexible pipe 4 inwalls are close to steel strand 1 by the hole at the bottom of retainer ring 5 tightly prick on steel strand, opposite side is in free state.The other end of slip casting flexible pipe 4 is earlier by pallet 6, and the arch hole 3-1 by arch hole slip casting disc 3 derives again, and the lockset 2 that is fixed is equipped with in the outer end of arch hole slip casting disc 3.During engineering construction, the steel strand 1 that are enclosed with slip casting flexible pipe 4 are put into boring, slurries are injected in the rock mass by an end of slip casting flexible pipe 4, and steel strand 1 and boring are combined closely, and have increased the anchored force of anchor cable and the globality of country rock.
