Description
Technical field
The utility model belongs to technical field of building construction, be specifically related to a kind of can the anchor cable construction system of being dismounted for multiple times.
Background technology
When excavating ground in building engineering construction, need to carry out temporary support to foundation ditch, to protect foundation ditch safety of surrounding environment, foundation ditch supports mainly to be needed to use anchor cable, bracing of foundation pit stake.Anchor cable, through weak rocks (soil) layer or slide plane by boring, anchor rod anchored for one end in hard rock stratum or soil layer, then stretch-draw is carried out at another free end, thus to unstable rock mass or the soil body, anchoring is carried out to rock stratum or soil layer applying pressure, its stream line is in the soil layer by steel strand inclined being squeezed into foundation ditch week side.In anchor cable construction, mostly need to carry out drilling operation, in hole, squeeze into water under high pressure while boring earth in hole is uniformly mixed, simultaneously to slip casting in hole, when drilling rod is beaten to desired location, the mixing of earth in boring, slurries solidifies rear formation anchoring section, then penetration concrete, is strained by steel strand and lock outside bracing of foundation pit stake after solidifying.
Along with development and the limited land development resource of China's urban construction, its deep-foundation pit engineering is on the increase, and the application of prestress anchorage cable gets more and more.But as a kind of temporary supporting measure, anchor cable cannot reclaim after supporting disabler, steel strand forever bury and cannot take out in underground, so not only result in great waste, and take a large amount of underground spaces for a long time, form underground garbage, cause underground environmental pollution, serious impact is all caused on the construction in adjacent plot and the long-term plan in city and sustainable development, but and recoverable prestress anchorage cable technology can well address this problem. because the removable anchor cable product design adopted is unreasonable, and underground building situation alters a great deal, problems can be produced during actual use.
As churning anchor cable of the prior art, in structure, this kind of anchor cable is carried out by many steel strand extruded sleeves crimping or by stress application, many steel strand being squeezed in certain space, then be fixed on one piece of loaded plate foremost, be connected with capping beam (enclosing purlin beam) by steel strand (bundle) again, be close to capping beam (enclosing purlin beam) in the outside of capping beam (enclosing purlin beam) and lock with ground tackle; There is following shortcoming: (1) uplift resistance is little, cost performance is low: anchor cable only has lowermost end stressed when Shi Hanzhang, substantially do not stress on 6 meters, front end, record according to pertinent literature, the potential stressing influence district of anchor pole or anchor cable is anchor cable (anchor pole) front end 6-7 rice, is less than 10 times of anchored end diameter, therefore, its back segment anchoring body can not play a role, thus causes its anchor cable (anchor pole) uplift resistance less, and cost performance is low; (2) poor stability: one piece of loaded plate that the in use all prestressing force of anchor cable all concentrates on by anchor cable lowermost end is stressed, thus make the anchoring body of parcel anchor cable (loaded plate) (cement slurry) be easy to be split, the poor stability of anchor cable, cause failure of cable foundation ditch Local Cracking, the generation foundation ditch total collapse that situation is serious.In construction technology, first use three leaf drill bits with certain inclination angle (needing to regulate according to design) pore-forming (reaming), in pore forming process, drilling rod from start to finish carries out high-pressure rotary-spray thus forms an anchoring body, after pore-forming reaches and needs length, extract whole drilling rod, then the loaded plate of anchor cable (have in plate a hole specialize in top anchor cable with) to be inserted on another kind of drill bit by force by anchor cable in hand-hole, and then secondary withdraws from all drilling rods, constructs complete; There is following shortcoming: (1) anchoring body destructible, inefficacy, the distortion of foundation ditch retrospective is large: drill bit from start to finish carries out high-pressure rotary-spray in pore forming process, by continuous print high-pressure rotary-spray, the actual as a whole cylinder formed, is a kind of connected mode of rigidity between it and capping beam (enclosing purlin beam).This anchor cable is without side pressure, and the frictional resistance that anchoring body one of only having anchoring body surface area and surrounding soil to be formed when stressed is single, retrospective distortion easily occurs anchor cable when stressed, causes foundation ditch displacement slowly to become large.Especially (come from dynamic load when loaded vehicle is passed by) when running into ground and having shock wave, move after peak value can occur for the destruction of anchoring body, anchoring body can destroy in segmentation, and then pointwise becomes face to destroy.Just as the reinforcing bar that hit with a hammer in concrete beam, just having started reinforcing bar can not loosen, and along with the frequent impact of shock wave, reinforcing bar can little by little loosen, until the whole body of rod destroys, lost efficacy, (2) anchor cable construction quality is unstable, discreteness is large: anchor cable when pore-forming with three leaf drill bits with certain inclination angle pore-forming (reaming), slip casting (its technique be limit reaming marginal not slurry), to treat after pore-forming again with another kind of drill bit to insert in anchor cable mesopore by force by anchor cable in burying, the deadweight of a drilling rod is only had when initial pore-forming, when laying anchor cable, the tip of drilling rod inserts in anchor cable loaded plate mesopore, at this moment (deadweight of the deadweight+anchor cable of total deadweight=drilling rod of drilling rod), and the place (depth of pore forming can reach 20-50 rice sometimes as required) of in hole tens meters far away is stretched at drilling rod, at this moment gravity when drill bit gravity has foremost been far longer than pore-forming, therefore, drilling rod track when the insertion track when anchor cable is laid and pore-forming is not on same straight line, that is the topmost loaded plate stressed member of anchor cable fails to be wrapped in centre or the substantial deviation anchoring body (cement slurry) of anchoring body (cement slurry), thus greatly reduce the bond stress (self-strength of churning anchoring body centered by high peripheral low) of anchoring body to supporting body, (3) difficulty laid by the anchor cable body of rod: anchor cable by by force in burying time, due to friction, the shearing of loaded plate and the hole wall surrounding soil body, along with the degree of depth of loaded plate jacking is more and more longer, a large amount of soil bodys can be gathered in the front end of loaded plate, thus infinitely increase the resistance of drilling rod jacking, when this resistance is added to enough large, anchor cable just cannot be laid (or lay length inadequate), and thus the uplift resistance of this anchor cable also just cannot meet design needs.In recovery, this kind of anchor cable reclaims difficulty, the rate of recovery is low, shortcoming is as follows: (1) this anchor cable is carried out by one or more steel strand extruded sleeve crimping or by stress application one or more steel strand are squeezed in certain space (being then fixed on one piece of loaded plate foremost): no matter be adopt the mode of " extruded sleeve " or adopt the mode of " one or more steel strand are squeezed in certain space ", all need previously to apply certain stress (according to existing product to him, its stress is generally about 120KN-180KN, by this stress, the assembly of neighbour is pressed together mutually), it just cannot carry and (not reach this prestressing force not have this prestressing, will come off or ultimate tension reduction when the locking of engineering anchorage cable stretching is stressed, affect deep pit monitor coefficient), on the contrary, after engineering failure of cable (using function terminates) ground tackle (capping beam section) unlocks, its end retracting device be fixed on loaded plate also must apply equal stress anchor cable device and could unlock, and that is whole anchor cable could reclaim, if and due to other reasons, as artificial construction reason, due to the cataclysm of sub-surface, carelessness of geological prospecting unit etc., cause a certain anchor cable limit resistance to plucking pulling force be less than before apply prestressing force, so it is buried underground and just cannot unlock with the tripper in the anchoring body of underground, the steel strand of this group anchor cable just cannot take out at all, so not only result in great waste, and take a large amount of underground spaces for a long time, form underground garbage, cause underground environmental pollution, serious impact is all caused on the construction in adjacent plot and the long-term plan in city and sustainable development, (2) outside being close to capping beam (enclosing purlin beam) carries out locking with ground tackle: along with State owned land is exploited natural resources the energy-conserving and environment-protective building that more and more rare and country advocates energetically, for improving land utilization ratio, the outer shear wall of its basement is all very near apart from bracing of foundation pit stake, especially second anchor cable is generally between 80-120cm, deduct the width 60-70cm enclosing purlin beam, actual clear spacing is not more than 50cm, and the anchor cable recovery scope of operation needs 75cm(jack length 45cm+ jack stroke 25cm+ lockset 5cm=75cm usually, if jack again its stroke little cannot unlock not), therefore, when in practical operation, first anchor cable steel strand reclaim often, operation side can meet, and cannot carry out when second anchor cable reclaims construction at all.
Also have a kind of with tubular type churning anchor cable in prior art, basic identical with above-mentioned churning anchor cable on product structure, difference is riding position and the construction technology of the anchor cable body of rod.In construction technology, this kind first rotates into a steel sleeve with tubular type churning anchor cable, and bath limit, limit rotates, rotation limit, limit pore-forming.After desired depth to be achieved, sleeve pipe stops entering being embedded in soil layer temporarily, and then the anchor cable body of rod is inserted in anchor cable hole from casing inner diameter, finally complete slip casting, anchor cable construction is complete; It is as follows to there is shortcoming in it: (1) is constructed slowly, affected programming: cause holding tube (cannot rotate because resistance becomes large steel sleeve), until whole sleeve pipe all cannot be fetched together with the anchor cable body of rod with casing pipe hole forming is as easy as rolling off a log.Especially in sandy soil layer, this phenomenon highlights more, have a strong impact on construction speed (2) body of rod and lay difficulty: sleeve pipe is when pore-forming, the inwall of sleeve pipe is easily filled by the soil body glowed, blocking, especially in argillic horizon, often need repeatedly to dredge casing inner diameter just can lay the anchor cable body of rod, sometimes an anchor cable all cannot be laid for one day, and anchor cable construction is stagnated substantially; (3) anchor cable uplift resistance is little, cost performance is low: anchor cable drilling diameter is less, and the diameter of anchor cable is also just equal to the diameter of steel sleeve, it also reduces the frictional resistance between anchoring body and the soil body simultaneously; (4) anchoring body destructible, inefficacy, the distortion of foundation ditch retrospective is large: anchor cable is stressed more single, and the distortion of foundation ditch retrospective is large.When running into the live load on ground, steel strand easily can little by little loosen, until whole anchoring body destroys, lost efficacy (concrete reason analyzes description) comprehensively.Same, in recovery, this kind of anchor cable reclaims difficulty, and the rate of recovery is low.
From the above, still there is anchor cable device low bearing capacity in prior art stream line structure and construction thereof, and anchor cable recovering effect is poor, unlocks difficulty, high in cost of production problem.In anchor cable (anchor pole) construction, a large amount of steel strand cannot be removed recovery, not only expend a lot of metal material and cause serious underground pollution, become the obstruction of successive projects construction, and can increase difficulty of construction, thus affect construction speed.
