Abstract

The utility model relates to a pneumatic Luoyang shovel, which belongs to an anchor-hole former, in particular to a soil-layer anchor-rod hole former which is used in foundation-pit support or side-slope support. The pneumatic Luoyang shovel is provided with a Luoyang shovel and has the key technology that the tail part of the Luoyang shovel is sequentially connected with an impactor, a drilling rod and a gas pipe, and the gas pipe is connected with an air compressor. The pneumatic Luoyang shovel has the advantages of low cost, deep hole-forming depth and high hole-forming speed.

Description

Pneumatic luoyang spade

Technical field:

Pneumatic luoyang spade belongs to the anchor hole perforating device, especially for the soil bolt perforating device in pattern foundation pit supporting structure or the slope retaining.

Background technology:

Existing pattern foundation pit supporting structure and slope retaining often adopt bolt support, and pore-forming adopts down-the-hole drill, auger or luoyang spade usually during the soil bolt construction.These are several to be the most effective existing pore-forming modes, but auger is less owing to power, and the one-tenth hole length can not be too dark; And the down-the-hole drill pore-forming, the short electronic down-the-hole drill of employing, long employing 70 type rigs, cost is higher like this, and speed is slower; Adopt the luoyang spade construction cost lower, but artificial because of adopting, depth of pore forming is not dark, and speed of fulfiling hole is slow.

Summary of the invention:

Problem to be solved in the utility model is exactly to provide the anchor pole that a kind of cost is low, depth of pore forming is dark, speed of fulfiling hole is fast perforating device at above deficiency.Its technical scheme is as follows:

It has luoyang spade, and its key technology is that the afterbody at luoyang spade connects impactor, drilling rod and tracheae successively, and tracheae connects air compressor.

The beneficial effect that compared with prior art the utlity model has is:

1, the utility model as soil taking shovel, is a power with the air with luoyang spade, provides impact force with impactor to soil taking shovel, and therefore, it is faster than luoyang spade; Again because of it does not need soil body fragmentation, so it is faster than auger and down-the-hole drill;

2, be power owing to having adopted compressed air, its depth of pore forming is greater than fluted drill and luoyang spade;

3, because of friction in the pore forming process, little to soil disturbance, can not cause disturbance to hole wall;

Be power requirement when impact is fetched earth during 4, owing to pore-forming, therefore an air compressor machine can be joined the pneumatic soil taking hole forming device of several covers, so its pore-forming cost is far below other rigs;

5, the utility model do not need large type drill to drive, so cost is lower, low price because machinery is less.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model luoyang spade structural representation;

Fig. 3 is the utility model user mode schematic diagram.

The specific embodiment:

Referring to Fig. 1-Fig. 3, the utlity model has luoyang spade 1, its key technology is that the afterbody at luoyang spade 1 connects impactor 3, drilling rod 4 and tracheae 5 successively, tracheae 5 connects air compressors.Being connected between luoyang spade 1 and the impactor 3: the luoyang spade afterbody inserts the impactor front port, and is fixing with pin 2.7 is domatic among the figure.

Operating principle of the present utility model is:

The utility model adopts luoyang spade 1 as soil sampler, hollow; Adopt impactor 3 as boost motor; , as catch bar luoyang spade 1 and impactor 3 are sent in the boring 6 with drilling rod 4; Power adopts compressed air, carries compressed air with tracheae 5.

Adopt compressed air to drive impactor 3 during work, produce impact power forward, in the luoyang spade soil sampler being impacted bury, when luoyang spade 1 all enters the soil body, rotary drill drilling rod 4, the soil body and the former soil body that enter in the luoyang spade are broken away from, outwards pull out drilling rod 4 then, luoyang spade 1 is extracted outside the hole, take off the soil body in the luoyang spade, repeat then to fetch earth, thus pore-forming.

Claims

1. a pneumatic luoyang spade has luoyang spade (1), it is characterized in that connecting impactor (3), drilling rod (4) and tracheae (5) successively at the afterbody of luoyang spade (1), and tracheae (5) connects air compressor.
