Abstract
The utility model discloses an anchor arm assembly used for construction with a soil body anchor arm. The assembly comprises a drill head, and the rear end of the drill head is detachably connected with the drill rod. A water feeder is arranged at the drill head. The anchoring end with the inherent stress thread is a square steel plate which is diagonally provided with grout injection pipes. The steel plate of the anchoring end is welded with a positioning steel plate. The utility model can ensure construction quality, improve efficiency and reduce cost. The utility model can be widely used to baffle soil, to dig underground continuous walls and protect foundation ditches.
Description
Technical field
The utility model relates to field of civil engineering, 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 anchor pole composite member of anchor pole.
Background technology
The prior art the most approaching with the utility model is a title: the patent of soil anchor job practices and the anchor pole composite member that adopted thereof, a kind of job practices and anchor pole composite member of soil anchor are disclosed, this invention is adopted grouting when creeping into, is lowered to the construction technology of anchor pole, simplify operation, improved efficient; The problem that exists is that dowel and drilling rod winding often take place in work progress, the back anchor pole takes place 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.Addressing this problem becomes urgent need.
The content of utility model
The purpose of this utility model is to overcome the deficiency that prior art exists, a kind of soil anchor construction anchor pole composite member is provided, this composite member comprises drill bit, but the rear portion of drill bit adopts disengagement type to be connected with drilling rod, the drill bit place is provided with water filling port, and drill bit is a sawtooth pattern, and the pore area Grouting Pipe is established at the diagonal angle on the prestressing force twisted wire anchored end employing square steel plate, the anchored end steel plate fixing steel plate of burn-oning, drill bit adopts key to be connected with drilling rod.Use the utility model in 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, can guarantee construction quality more reliably, raise the efficiency, thereby reduce cost by drilling rod self high-pressure feed water; Owing to have sawtooth on the drill bit, therefore making and downcutting soil layer is bar shaped, and more easy-to-discharge slag improves rate of penetration; Can propose once grouting behind the drilling rod because drill bit creeps into Grouting Pipe, make grouting amount obtain metering and confirm and can bring two Grouting Pipe into, carry out splitting and mend slurry, improve by force, make construction means more flexible, quality is easier to control.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
The specific embodiment
Give an actual example below this utility model is described in detail.
Soil anchor construction anchor pole composite member, comprise drill bit 6, but the rear portion of drill bit adopts disengagement type to be connected with drilling rod 7, the drill bit place is provided with water filling port 9, the surface of sawtooth pattern drill bit 1 is a sawtooth pattern, prestressing force twisted wire 4 anchored end 3 adopt on the square steel plates diagonal angle to establish pore area Grouting Pipe 5, the anchored end steel plate fixing steel plate 2 of burn-oning, and drill bit 6 adopts keys 8 to be connected with drilling rod 7.
Adopt the utility model construction to comprise the steps:
A utilizes roof-bolter boring, and by drilling rod self high-pressure feed water, current reach high pressure soil layer is formed cutting at the place of creeping in the boring procedure;
B, drill bit are that serration type makes that to downcut soil layer be bar shaped, easier discharge, and drill bit adopts plain bearing or pressure bearing to be connected with prestressing force twisted wire anchored end, and attaches a Grouting Pipe, creeps into projected depth with drill bit;
C, after drilling rod took out, prestressing force twisted wire anchored end was stayed foot of hole with Grouting Pipe and drill bit, carries out slip casting (can be cement paste or cement mortar) by Grouting Pipe then, after slip casting reaches designing requirement, formed prestressed anchor.
Claims (2)
1, a kind of soil anchor construction anchor pole composite member, it is characterized in that: it comprises drill bit, but the rear portion of drill bit adopts disengagement type to be connected with drilling rod, the drill bit place is provided with water filling port, drill bit is a sawtooth pattern, prestressing force twisted wire anchored end adopts on the square steel plate diagonal angle to establish the pore area Grouting Pipe, the anchored end steel plate fixing steel plate of burn-oning.
