Abstract
The utility model discloses a pressure-bearing water-sand-layer anchor rod mounting structure which comprises a drill hole. A steel sleeve capable of blocking sand layer water and preventing cement paste from running off is arranged in the drill hole, an anchor rod is arranged in the steel sleeve, and cement mortar is filled in the steel sleeve. The pressure-bearing water-sand-layer anchor rod mounting structure has the advantages of simple structure, convenience for construction, greatly-lowered construction cost, high reliability, high working efficiency, capability of guaranteeing grouting quality of the anchor rod, and the like.
Description
Technical field
The utility model relates to a kind of rockbolt installation structure, particularly a kind of artesian water layer of sand rockbolt installation structure.
Background technology
At present, scientific and technical high speed development along with China, Building technology also develops rapidly, building is gradually to the long-pending future development of high-rise and large face (body), nearly all high level, building have basement, underground garage etc., this also makes anchor pole widely apply in the anti-floating of engineering works, structure and foundation pit supporting system, and traditional handicraft is continued to use in existing anti-float anchor rod construction always, adopts the construction technology of mud off pore-forming.In traditional construction technology, the slip casting plant equipment of using in anchor bolt construction is can't be high in groundwater table, underground water is abundant especially, and hydraulic pressure is large especially, and is again slip casting in silt soil strata on layer of sand, slip casting is more, the cement waste is larger, does not probably reach the curing sealing namely breakdown, even after the rig pore-forming, during slip casting, cement mortar runs off seriously, can't moulding.Also can cause simultaneously construction quality to be difficult for guaranteeing, be difficult to produce a desired effect, so the prior art Shortcomings.
Summary of the invention
The purpose of this utility model is: provide a kind of artesian water layer of sand rockbolt installation structure that a kind of simple in structure, safe and reliable, easy construction, efficient are high, can guarantee the bolt grouting quality, to overcome the deficiencies in the prior art.
The utility model is to consist of like this: a kind of artesian water layer of sand rockbolt installation structure, comprise boring, and be provided with the steel sleeve that can stop layer of sand water and prevent the cement paste loss in boring, be provided with anchor pole in steel sleeve, filling with in steel sleeve has cement mortar.
Be provided with 2 joint～6 joint steel sleeves in boring.
Two adjacent joint steel sleeves connect by the male and female Threaded Connector Coupling.
Owing to having adopted technique scheme, during the utility model work, at first utilizing slewing drilling machine to hole, then steel sleeve is installed in boring, insert anchor pole at steel sleeve, to carrying out common pressure grouting in the pre-buried steel sleeve pipe, utilize the pre-buried steel sleeve pipe to stop layer of sand water and prevent that cement paste runs off, and guarantees the construction quality of anti-float anchor rod so better; Compared with prior art, the utility model not only has simple in structure, the advantage of easy construction, and have that construction cost is low, easy to use, reliability is high, high efficiency, can guarantee the bolt grouting quality etc. advantage.
Description of drawings
Fig. 1 is the utility model structural representation;
Description of reference numerals: 1-boring, 2-steel sleeve, 3-anchor pole, 4-cement mortar, 5-Grouting Pipe.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: a kind of artesian water layer of sand rockbolt installation structure, comprise boring 1, be provided with the steel sleeve 2 that can stop layer of sand water and prevent the cement paste loss in boring 1, be provided with anchor pole 3 in steel sleeve 2, in the interior filling of steel sleeve 2, cement mortar 4 is arranged.
Be provided with 2 joint～6 joint steel sleeves 2 in boring 1.
Two adjacent joint steel sleeves 2 connect by the male and female Threaded Connector Coupling, and the male and female Threaded Connector Coupling is existing a kind of part connecting structure.
during work, at first utilize slewing drilling machine to hole, guarantee the levelness of borer frame and the verticality of vertical shaft in boring procedure, after boring, the pressure-air that utilizes air compressor machine to produce carries out deslagging to boring, then steel sleeve 2 is installed in boring, according to the degree of depth in different holes, 2 joint～6 joint steel sleeves 2 are installed, two adjacent joint steel sleeves 2 connect by the male and female Threaded Connector Coupling, then insert anchor pole 3 in boring, at the bottom of the vertical patchhole of anchor pole 3, be placed in securely anchor hole central authorities, then carrying out slip casing by pressure to holing in 1 by Grouting Pipe 5, injecting paste material adopts cement mortar 4 or pea gravel concreten, carry out at last sealing off and covering anchorage.
