The anchor cable grout stop plug has the advantages that the structure is simple and operation is convenient; pulling resistance of an anchor cable in a permanent slope support project is improved and project cost is reduced; cement paste is not needed for corrosion resistance of a temporary support project and manufacturing cost is reduced; loss of prestress of the anchor cable can be reduced for a permanent reinforcement project.
Description
Technical field:
The utility model relates to a kind of anchor rope grouting-stop plug, belongs to Geotechnical Engineering.
Background technology:
Traditional anchor rope grouting technique, is not used sealing device, at the bottom of directly Grouting Pipe being seated to hole with anchor cable, takes gravity flow slip casting from bottom to top, till filling with boring.There is following shortcoming:
(1) because of the limitation of construction technology, when anchor cable is laid, be difficult to guarantee the straight of anchor cable.Adopt disposable slurry injection technique, in hole, anchoring section and free segment are all full of slurries, after slurries solidify, while applying prestressing force, because of free segment anchor cable not straight, can produce larger side friction, cause the stressed minimizing of anchoring section, the distortion of tensioning fixation power, As time goes on, can cause larger loss of prestress, conventionally need to take repeatedly to compensate stretch-draw.
(2) the darker anchor cable of those slide planes is reinforced to project, particularly to temporary lining object of construction production (as provisional pattern foundation pit supporting structure), free section of anchor cable only needs to carry out general preservative treatment (generally adopt on steel strand smear butter plastic pipe-covered), and traditional slurry injection technique can be wasted a large amount of cement.
(3) take gravity flow slip casting, only depend on the head pressure of slurries, higher grouting pressure cannot be provided, cannot make slurries effectively be spread, cannot effectively improve the uplift resistance of anchor cable.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of anchor rope grouting-stop plug is provided.
Anchor rope grouting-stop plug of the present utility model, by which is provided with the first coniform hole (6), the second coniform hole (8) and the 3rd coniform hole (9), and the support (7) with the reserved bellmouth of U-lag being connected with Grouting Pipe (1), stack (4) and steel strand (2) respectively by the first coniform hole (6), the second coniform hole (8) and the 3rd coniform hole (9); Be placed in the air bag (3) in the U-lag of support (7); The the first vizored cone seal cushion rubber (11) and the second vizored cone seal cushion rubber (12) that are placed in gap between Grouting Pipe (1), stack (4), steel strand (2) and the first coniform hole (6), the second coniform hole (8) and the 3rd coniform hole (9) form.This anchor rope grouting-stop plug plays seal isolation effect during to the slip casting of anchor cable hole anchoring section, and anchoring section is carried out to slip casing by pressure, guarantees slurries diffusion effect, improves anchor cable uplift resistance.
The described support (7) with the reserved bellmouth of U-lag adopts general duroplasts to make.Diameter is determined according to design aperture.
The first described vizored cone seal cushion rubber (11) and the second vizored cone seal cushion rubber (12) adopt general purpose synthetic rubber.
Described air bag (3) adopts the rubber that retractility is good to make, and after inflation, with hole wall close contact, in order to confining zone U-lag, reserves the space between bellmouth support (7) and hole wall.
The utility model adopts the material of market sale to prepare according to a conventional method.
The beneficial effects of the utility model are:
1, in permanent slope support engineering, anchor cable grouting is become to pressure type grouting from gravity flow, improve preferably the inclusion enclave effect of anchoring section, thereby greatly improved the uplift resistance of anchor cable.Thereby so just can when design, shorten anchor cable length or reduce anchor cable quantity and save construction costs.
2, to temporary lining object of construction production (as provisional pattern foundation pit supporting structure), adopt this technology, free section of anchor cable only needs to carry out general preservative treatment (that is: generally adopt on steel strand smear butter plastic pipe-covered), needn't carry out with cement paste anticorrosion, saving construction cost.
3, for permanent stabilization works, adopt this technology, first anchoring section is carried out to slip casting, after tensioning fixation, again free segment is carried out to slip casting, can reduce the loss of prestress of anchor cable.
Accompanying drawing explanation:
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the A-A sectional view with the support (7) of the reserved bellmouth of U-lag.
Fig. 3 is the B-B sectional view with the support (7) of the reserved bellmouth of U-lag.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in detail.
Anchor rope grouting-stop plug of the present utility model, by which is provided with the first coniform hole 6, the second coniform hole 8 and the 3rd coniform hole 9, and the support 7 with the reserved bellmouth of U-lag being connected with Grouting Pipe 1, stack 4 and steel strand 2 respectively by the first coniform hole 6, the second coniform hole 8 and the 3rd coniform hole 9; Be placed in the air bag 3 in the U-lag of support 7; Be placed in Grouting Pipe 1, stack 4, steel strand 2 and the first vizored cone seal cushion rubber 11 and the second vizored cone seal cushion rubber 12 by gap between the first coniform hole 6, the second coniform hole 8 and the 3rd coniform hole 9 form.
When anchor cable is made, support 7, air bag 3 with the reserved bellmouth of U-lag are fixed on to anchorage cable anchoring section and free segment junction, and Grouting Pipe 1, stack 4, the first vizored cone seal cushion rubber 11 and the second vizored cone seal cushion rubber 12 and gas tube 5 be installed, after anchor cable is laid and is put in place, with air pump, by gas tube 5,10 pairs of air bags 3 of air valve, carry out pneumatic compression, after air bag 3 inflations, the space sealing by the support 7 with the reserved bellmouth of U-lag with anchor cable hole.Support 7 and the space between Grouting Pipe 1, stack 4 and steel strand 2 with the reserved bellmouth of U-lag are sealed by the first vizored cone seal cushion rubber 11 and the second vizored cone seal cushion rubber 12.
Mounted anchor rope grouting-stop plug with the anchor cable of making by the anchor cable hole of putting in predetermined inclination and orientation.Adopt grouting equipment that cement grout is injected to anchor cable hole by Grouting Pipe 1, reach predetermined grouting pressure and stop slip casting.
Through reality, use and show: can provide enough pressure for anchor rope grouting, grouting pressure is brought up to 0.5～2MPa, effectively improves the range of scatter of slurries, thus the uplift resistance of raising anchor cable, and when particularly anchoring section stratum is soil layer, uplift resistance improves more obvious.
