Abstract

The invention discloses a multi-spring-bolt-pin self-locking type anchor rod and an application method thereof. The multi-spring-bolt-pin self-locking type anchor rod comprises a plurality of anchor rod connectors. Screw holes are formed in one ends of the anchor rod connectors in the length direction of the anchor rod connectors, and threaded rods matched with the screw holes are arranged at the other ends of the anchor rod connectors. A plurality of sets of spring bolt pins are arranged on the outer side walls of the middles of the anchor rod connectors. The application method of the multi-spring-bolt-pin self-locking type anchor rod comprises the following steps that 1, the multiple anchor rod connectors are sequentially connected to form the anchor rod through the screw holes and the threaded rods at the two ends of the anchor rod connectors; 2, the anchor rod is inserted into a drill hole, and at this time the spring bolt pins are spread automatically and clamped in a counter bore which is drilled in advance; 3, the drill hole is filled with mortar, and after the mortar is solidified, the method is completed. According to the multi-spring-bolt-pin self-locking type anchor rod and the application method thereof, the contact area of the anchor rod and the anchoring surface is increased, the multi-directional friction force is increased, so that the pulling resistance of the anchor rod is increased by dozens of times, and the safety is further improved effectively.

Description

A kind of spring is many from pin anchor pole and using method thereof

Technical field

The invention belongs to the anchoring field of anchor pole, particularly relate to a kind of spring many from pin anchor pole and using method thereof.

Background technology

In recent years, the development of domestic and international mooring rod technique reaches its maturity, and the type of anchor pole also gets more and more, and anchor rod anchored application in engineering is more and more extensive, the problem thereupon brought is also more and more distincter, and this has driven the enthusiasm that numerous scientific and technical personnel study further to mooring rod technique.Frictional resistance deficiency is often there is during common bolt design, the problem that Soil Anchor Design length is long, suitably improving the strength of materials, under strengthening the prerequisite of the adhesion stress of the body of rod and slurries etc., how to improve the uplift resistance of anchor pole further, suitably shortening rock-bolt length, make it in a more rational scope, is the new direction of anchor pole development, new problem.Be engaged in tunnel, deep foundation pit supporting construction for many years, the problems such as the uplift resistance deficiency often running into anchor pole, the anchoring section calculated are long, these problems annoying person skilled for a long time always.How to solve the emphasis that the length of saving anchor pole and the uplift resistance increasing anchor pole and anchored force are research.

Summary of the invention

The object of the present invention is to provide a kind of spring many from pin anchor pole and using method thereof, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, present invention employs following technical scheme:

A kind of spring is many from pin anchor pole, comprise several anchor pole connectors, screw is offered along anchor pole connector length direction in described anchor pole connector one end, and its other end is the screw rod coordinated with described screw, and in the middle part of described anchor pole connector, lateral wall is provided with some groups of spring pins.

Preferably, the quantity often organizing spring pin is two, and two spring pins are arranged along described anchor pole connector axisymmetrical.

Preferably, the group number of the spring pin on each anchor pole connector is no more than 3 groups.

The many usings method from pin anchor pole of spring, comprise the following steps:

1) by the screw at anchor pole connector two ends and screw rod, some anchor pole connectors are connected to form anchor pole successively;

2) inserted in boring by anchor pole, at this moment spring pin is opened automatically, in the stuck reaming having bored in advance;

3) in boring, fill mortar, treat that mortar solidifies.

Compared with prior art, beneficial effect of the present invention is as follows:

The present invention is directed to drilling rod to support the use, by anchor pole being arranged to the anchor pole connector of some flexible connections, and spring pin is set on anchor pole connector, increase anchor pole and anchoring and contact area, increase multidirectional frictional force, make the uplift resistance of anchor pole increase decades of times, meet construction technical requirement, safety is effectively improved further.

Accompanying drawing explanation

Fig. 1 is the structural representation from pin anchor pole.

Detailed description of the invention

Below in conjunction with embodiment, preferred embodiment of the present invention is described in further detail.

As shown in Figure 1, a kind of spring is many from pin anchor pole, comprise several anchor pole connectors 1, screw 11 is offered along anchor pole connector 1 length direction in described anchor pole connector 1 one end, and its other end is the screw rod 12 coordinated with described screw 11, in the middle part of described anchor pole connector 1, lateral wall is provided with some groups of spring pins 13.

In order to further optimisation technique scheme, the quantity often organizing spring pin 13 is two, and two spring pins 13 are arranged along described anchor pole connector 1 axisymmetrical.The group number of the spring pin 13 on each anchor pole connector 1 is no more than 3 groups.

The many usings method from pin anchor pole of spring, comprise the following steps:

1) by the screw 11 at anchor pole connector 1 two ends and screw rod 12, some anchor pole connectors 1 are connected to form anchor pole successively.

2) inserted in boring by anchor pole, at this moment spring pin 13 is opened automatically, in the stuck reaming having bored in advance.

3) in boring, fill mortar, treat that mortar solidifies.

The present invention is directed to feature and the difficult point of anchor bolt construction technology, a kind of spring is proposed many from pin anchor pole and using method thereof, adopt novel assembling multi-pin formula anchor pole, adopt simultaneously and form multistage reaming construction method with in enlarged footing drilling rod, by adopting assembling multi-pin formula anchor pole, can adopt and multiple pin anchor rod member is set, thus minimizing rock-bolt length, increase anchored force, spring pin 13 can be arranged on both direction and four direction and multi-direction on, meet different requirement of engineering.Support the use for drilling rod, thus increase anchor pole and anchoring and contact area, increase multidirectional frictional force, make the uplift resistance of anchor pole increase decades of times, meet construction technical requirement, safety is effectively improved further.

Above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
