Abstract
The utility model relates to a novel soil body anchor rod construction assembly device, which comprises a drill head and an anchorage disk, wherein, the rear part of the drill head is connected with a drill rod by means of a catcher screwed connection; the drill head is provided with a water injection opening; the drill head is in the shape of a sawtooth; the end part is provided with an alloy drill leaf; a prestressing force twisted line anchorage end adopts a steel strand hole arranged on the opposite angle of the disk; an anchorage end steel plate is round and can be rotated relatively to the drill head during the drilling period. The utility model supplies water through the high pressure of the drill rod, enables the water flow to reach the high pressure and form shear action at the drilling place, and improves drilling speed and efficiency; the trivalvular sawtooth-shaped drill head causes a cut soil layer to be a strip, results in easier deslagging and increases the drilling speed; the drill head and the prestressing force twisted line anchorage end adopt a disk connection, thereby preventing the steel strand from twisting the drill rod and ensuring the footage depth. The soil body anchor rod construction assembly device can ensure the construction quality and the technique, improve the efficiency so as to lower the cost, and can be widely applied to the construction apparatus of the anchor rod formed in the tension and the withdrawal-resistance of the soil layer for soil-retaining, continuous concrete wall and foundation ditch support.
Description
Technical field
The utility model relates to the civil engineering instrument, particularly relates to retaining soil, diaphragm wall, and pattern foundation pit supporting structure is used, tension, resistance to plucking in soil layer and form the construction composite member of anchor pole.
Background technology
Dowel and drilling rod winding often take place in the process of anchor bolt construction at present, and anchor pole can't creep into and should reach the degree of depth, and it is serious and can't remedy to produce consequence, causes in the design process safety factor excessive, and waste seriously.Drilling rod slip casting in addition, when drilling rod proposed, cement paste was spoilt and is contracted, and the disappearance amount is with carrying with benefit, and mass effect can't check that artificial governing factor is excessive, causes the quality situation uncertain, and the cement paste waste is huge, and addressing this problem becomes urgent need.
The content of utility model:
Overcome the deficiencies in the prior art, provide a kind of efficient height, construction quality good, the novel soil anchor construction composite member that cost is low, reduce the drill bit waste.This composite member comprises drill bit, anchoring disk, the rear portion of this drill bit and drilling rod adopt the catcher screwed connection, the drill bit place is provided with water filling port, drill bit is a zigzag, afterbody also has alloy and bores leaf, the steel strand hole is established at the diagonal angle on the prestressing force twisted wire anchored end employing disk, and the anchored end steel plate is an annular, in drilling process mutual rotation can take place with drill bit.The construction of employing the utility model by drilling rod self high-pressure feed water, makes current reach high pressure at the place of creeping into speed and efficient is advanced in soil layer formation shear action raising commentaries on classics; Drill bit is that three lobe zigzag make that to downcut soil layer be bar shaped, and more easy-to-discharge slag improves rate of penetration, and drill bit adopts disk to be connected with prestressing force twisted wire anchored end, prevents that steel strand from twining drilling rod, the assurance advanced depth; Afterbody also has alloy and bores leaf, is convenient to oppositely fetch earth, and the result of above-mentioned every technological synthesis effect makes the utility model can better guarantee construction quality, makes technology more guaranteed, raises the efficiency, thereby reduces cost.
Fig. 1 is a front view of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the utility model duty view.
The specific embodiment:
A kind of novel soil anchor construction composite member, it comprises drill bit 1, anchoring disk 2, the rear portion of this drill bit and drilling rod adopt the catcher screwed connection, the drill bit place is provided with water filling port 3, drill bit is a zigzag, and afterbody also has alloy and bores leaf 4, and steel strand hole 5 is established at the diagonal angle on the prestressing force twisted wire anchored end employing disk, the anchored end steel plate is an annular, in drilling process mutual rotation can take place with drill bit.The job practices that the utility model carries out soil anchor comprises the steps:
A, utilize the boring of geological drilling rig or roof-bolter, by drilling rod self high-pressure feed water, make current reach high pressure at the place of creeping into soil layer is formed shear action in the boring procedure.B, drill bit are that three lobe serration types make that to downcut soil layer be bar shaped, easier discharge, and drill bit afterbody band alloy bores leaf and more helps Kelly Stubb and remove.Drill bit adopts disk to be connected with prestressing force twisted wire anchored end, proceeds to projected depth with bit drills.After C, drilling rod took out, prestressing force twisted wire anchored end disk and twisted wire were stayed foot of hole together, carry out slip casting (can be cement paste or cement mortar) by drilling rod then, after slip casting reaches designing requirement, formed prestressed anchor.In above-mentioned soil anchor job practices, in the step a boring procedure,, make current reach high pressure at the place of creeping into speed and efficient are advanced in soil layer formation shear action raising commentaries on classics by drilling rod self high-pressure feed water.Step b, drill bit are that three lobe zigzag make that to downcut soil layer be bar shaped, and more easy-to-discharge slag improves rate of penetration, and drill bit adopts disk to be connected with prestressing force twisted wire anchored end, prevents that steel strand from twining drilling rod, the assurance advanced depth.
