Description

Soil nailing wall anchor rod striking head

Technical Field

The utility model relates to a foundation ditch support soil nail wall construction field, concretely relates to soil nail wall stock hits head.

Background

When the anchor is spouted to soil nail wall, bury behind the stock need drilling, but when geology is silty sand bed, the pore-forming is difficult, causes very big influence to construction progress, quality, and repeated drilling is comparatively frequent. In this case, the soil nail is directly driven into the soil and then grouted, but in the process of anchoring the soil nail into the soil, the anchor rod machine is used to strike the tail end of the steel pipe soil nail anchor rod, so that the tail end of the steel pipe soil nail is deformed due to vibration load, and the tail end part cannot be used.

The Chinese utility model patent CN207775875U discloses a soil nailing wall anchor rod end reinforcing sleeve which is characterized by comprising a bottom sleeve, a hoop and a top sleeve; the bottom sleeve is a steel sleeve with a bottom and is sleeved at the tail end of the anchor rod of the soil nailing wall so as to increase the stress area of the tail end of the anchor rod of the soil nailing wall; the top sleeve is a steel sleeve without a bottom, is sleeved on the soil nailing wall anchor rod and is used for lengthening the bottom sleeve and preventing the bottom sleeve from falling off in the striking process; the clamp is used for clamping the bottom sleeve and the top sleeve. Compared with the prior art, the beneficial effects of the utility model reside in that, the utility model provides a soil nail wall stock end reinforcing sleeve through setting up the great sleeve of end area at soil nail wall stock end, increases the terminal lifting surface area of stock and atress performance, has avoided nailing the in-process into the earth, and steel pipe soil nail end is warp because of vibrations load, leads to the unable condition of using in terminal position. The reinforcing sleeve of this patent has protected steel pipe soil nail end, however, during the use, need install on stock machinery after this reinforcing sleeve and stock combination, then hit and beat this reinforcing sleeve anchor nail that buries, in the construction, need frequent installation and dismantle and install again on stock machinery behind the reinforcing sleeve, complex operation. And indirectly transmit the force to the end of the bolt by striking the reinforcement sleeve, a part of the striking force is lost. In addition, the tail end of the reinforcing sleeve is closed, so that the tail end of the anchor rod is extruded and tensioned to be clamped in the reinforcing sleeve in striking, material waste is caused, and normal construction is even affected.

SUMMERY OF THE UTILITY MODEL

Install and dismantle frequently after solving above-mentioned prior art fixed sleeve needs to make up with the stock, hit and beat and consolidate the sleeve anchor and go into stock loss hitting power and consolidate the sleeve end and seal and can lead to the stock card to die the technical problem in consolidating the sleeve, the utility model provides a hit head with stock mechanical fixed connection's soil nail wall stock.

The utility model adopts the technical proposal that: the utility model provides a soil nail wall stock head of beating, includes the sleeve, the stock is established to sleeve hole cover, and wherein, telescopic one end connection has the fixed plate, and the fixed plate is used for fixed connection stock machinery, be equipped with the telescopic guiding hole of intercommunication on the fixed plate, the guiding hole is greater than towards sleeve side opening towards stock machine side opening, the guiding hole is provided with the rubber pad towards sleeve side opening.

Further, the diameter of the opening of the guide hole towards the side of the anchor rod machine is 1.2 times of the outer diameter of the anchor rod.

Further, the guide hole is a tapered hole.

Further, the guide hole is a bowl-shaped hole.

Further, the outside of sleeve is provided with the reinforcing bar.

The utility model has the advantages that the rubber pad is arranged at the tail end of the anchor rod and the sleeve is used to protect the tail end of the anchor rod from deformation and damage; the striking head of the utility model is arranged on the anchor rod machine, so that the anchor rod can be directly replaced, and the operation is simple and convenient; the anchor rod is directly hit by the anchor rod machine, so that the loss of force is avoided, and the anchor rod cannot be blocked in the sleeve.

The mark in the figure is: 1. a sleeve; 2. a fixing plate; 3. a guide hole; 4. a rubber pad; 5. and reinforcing the steel bars.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following figures are combined to describe the soil nailing wall anchor rod striking head in further detail.

Please refer to fig. 1, a soil nail wall stock striking head, including sleeve 1, the stock is established to 1 interior pot head of sleeve, the one end connection of sleeve 1 has fixed plate 2, fixed plate 2 is used for fixed connection stock machinery, be equipped with the guiding hole 3 of intercommunication sleeve 1 on the fixed plate, guiding hole 3 is greater than towards the sleeve side opening towards stock machine side opening, make the stock machine hit when beating the terminal position of guiding the stock with the tup, guiding hole 3 is provided with rubber pad 4 towards the sleeve side opening, as the buffering of hitting the stock, the protection stock is terminal.

In this embodiment, fixed plate 2 is made by a square steel plate, and the recess is made to fixed plate 2 openly, and the open-ended size of orientation stock machine side is 1.2 times of stock external diameter, and the size of orientation 1 side opening of sleeve is the same with the diameter of 1 hole of sleeve. The diameter of the inner hole of the sleeve 1 is slightly larger than the outer diameter of the anchor rod. The back of the fixing plate 2 is welded with a sleeve 1 made of a steel pipe through cutting, and the sleeve is polished. Two groups of two parallel reinforcing steel bars 5 are welded on the outer side of the sleeve 1 to serve as anti-slip measures and reinforce the sleeve 1.

Before using, place the stock afterbody with rubber pad 4, prevent the loss stock, will the utility model discloses a stock is beaten the head and is connected fixedly with stock machinery, can use by construction.
