Description
Technical field
The present invention relates to a kind of Pulling-Resistant Anchor Rod slip casting drainage arrangement of carbonate rock area in the case of having artesian head and
Its construction method, belongs to bolt grouting technical field.
Background technology
In recent years, with the large-scale development of the underground space, increasing problem along with underground engineering development and
Produce, wherein underground structure is because the example that water buoyancy is damaged is no lack of minority.Some engineerings in work progress, due to which
The top number of plies is few, and dead load is often insufficiently resistant to the buoyancy of underground water generation, occurs in that basement bottom board is large-area and opens
Split, heave；The underground structure of some engineerings integrally floats, and causes serious economic loss.Therefore, anti-floating problem one
It is directly the problem of project planner's attention.
For the Anti-floating design of basement bottom board, in engineering, common method for designing has ballast method (as increased base plate thickness
Or overlying soil thickness) anti-floating, uplift pile anti-floating, anti-float anchor rod anti-floating etc..When arranging anti-float anchor rod, anchor pole is by high pressure injection
Slurry is fixed in basic following ground, is anchored in basis, and the withdrawal resistance under water buoyancy effect is provided to basement, anti-with other
Floating measure is compared, fast because having the advantages that low cost, the strong adaptability to site soil layers, speed of application, anti-in basement at present
It is widely used in float meter.However, in carbonate rock area, due to special karst landform, underground storage is big
The underground water of amount, level of ground water are higher so that as hydraulic pressure is big when anti-float anchor rod slip casting is anchored, and slurries are not yet able to do in time solidification just
Lifted by water pressure, it is final to increase the successful difficulty of slip casting, even result in slip casting failure.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of carbonate rock area Pulling-Resistant Anchor Rod slip casting drainage arrangement and its
Construction method, solves the problems, such as carbonate rock area as hydraulic pressure is high, anti-float anchor rod grouting difficulty.
The technical scheme that the present invention takes is：A kind of carbonate rock area Pulling-Resistant Anchor Rod slip casting drainage arrangement, including steel pipe
With anti-float anchor rod, fix and extend in injected hole side by side by colligation with steel pipe for anti-float anchor rod, and steel pipe is extend into one section in injected hole
On be provided with sieve aperture.
Preferably, above-mentioned outer diameter of steel pipes is 20-40 millimeters.
Preferably, above-mentioned sieve aperture spreads all over and stretches into one section of steel pipe pipe shaft of injected hole, screen-aperture 8-10 millimeters.
Preferably, above-mentioned sieve aperture is 300-600 millimeters along length of steel pipe direction pitch of holes.
Preferably, interlaced arrangement between above-mentioned sieve aperture tandem.
A kind of construction method of carbonate rock area Pulling-Resistant Anchor Rod slip casting drainage arrangement, the method are comprised the following steps：
Step one, after artesian water water level in foundation ditch is evacuated to below the bottom of hole, surveying and locating positions the position of injected hole, and performs
Mark；
Step 2, is drilled to injected hole mark downward vertically using rig, is drilled into specified drilling depth；
Step 3, the good steel pipe of colligation side by side and anti-float anchor rod are put in injected hole；
Step 4, carries out high-pressure slip-casting to drilling.
Beneficial effects of the present invention：Compared with prior art, the present invention is tied up by the steel pipe with sieve aperture and Pulling-Resistant Anchor Rod
In fixed implantation bolt grouting hole, draining pressure release is carried out by sieve aperture during slip casting, grouting pressure is effectively reduced, slip casting is reduced difficult
Degree, faster, especially secondary grouting effect more preferably, efficiently solves carbonate rock area as hydraulic pressure is high, anti-float anchor rod for slip casting
The problem of grouting difficulty, the present invention also have simple structure, low cost, it is easy to operate the characteristics of.
