Abstract

The utility model relates to a hydraulic propping up pipe forming hole equipment, which comprises a jack, a picket tine, a steel pipe and a steel pipe assembly. The steel pipe assembly is made of a reinforcing steel bar, a steel twist wire, a profiled bar and a slurry pouring pipe. The jack is fixed with the steel pipe assembly. The picket tine is installed at the front of the steel pipe assembly and connected with the assembly by the bear-insertion method. The novel equipment utilizes a simplified construction way, greatly reducing the construction cost; the forming hole procedure has no collapse hole, the slurry pouring pipe is not built up, and the second pouring slurry can still be made. The pouring quality is guaranteed easily; the poured slurry is formed into an anchor pole after the slurry is directly poured or the steel pipe is drawn; therefore in the process of the construction the problems which the anchor pole is provided with the steel twist wire and the slurry pouring pipe winds the drilling are solved. So the pouring depth is met, the slurry pouring pipe is not built up and the quality of the construction is guaranteed; that the prefabricate component of the concrete is directly propped up forms a soil nail or an anchor pole. This construction becomes more simple and very low cost. At the same time it can be widely used in the block soil construction for the pit support. The equipment realizes that the hole can be directly formed in the soil layer or the linetype steel components or the slurry pouring pipes are transmitted into the soil.

Description

A kind of hydraulic ceiling coil pore-forming equipment

Technical field

The utility model relates to field of civil engineering, particularly relate to that retaining soil, pattern foundation pit supporting structure are used, directly pore-forming or Xiang Tuzhong carry the construction technology and the equipment of Steel section member and Grouting Pipe in soil layer.

Background technology

The job practices of carrying out soil nailing wall and anchor pole at present generally is to adopt artificial or machinery is cut the earth, and speed of application is slow, and is subjected to the influence of soil layer geological condition, and most cases can't pore-forming; In order to address this problem, people have done multiple effort, Chinese patent discloses a key name for No. 200520011116 and has been called: underground hydraulic ceiling coil machine patent, a kind of underground hydraulic ceiling coil machine is disclosed, form by frame, two two-way cylinder, draw back plate, support bar and thrust plate of lifting one's head, the front portion of push-bench is a frame, the centre is provided with draw back plate, the rear portion of oil cylinder connects thrust plate, both sides are respectively equipped with a support bar, front end at oil cylinder is provided with piston rod, is provided with hand-operated direction valve on a side support bar.Front end at support bar has the adjustment leading screw, is provided with push-rod hole in the centre of thrust plate.This novel device need not excavate can finish pipeline etc. underground and cross operation; The problem that exists is that the complicated cost of device structure is higher, uses inconvenient; 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, and a kind of hydraulic ceiling coil pore-forming equipment is provided, and steel pipe etc. is directly headed in the soil layer, and job practices is simplified, and guarantees construction quality more reliably, raises the efficiency, thereby reduces cost.Hydraulic ceiling coil pore-forming equipment, it comprises jack, the stake point, steel pipe, the reinforcing bar of packing in the steel pipe, steel strand, shaped steel and Grouting Pipe constitute combined member, and the tail end of jack and combined member is connected, the stake point is installed in the front portion of combined member, and the stake point adopts bayonet joint with combined member.

The utility model directly heads into steel pipe etc. in the soil layer, and job practices is simplified, and cost reduces greatly.Head into line style steel member (steel pipe, shaped steel or reinforcing bar etc.) and directly form soil nailing, or head into steel pipe grouting behind shaft or drift lining formation soil nailing, in work progress, the soil body is produced compacted effect, simple and efficient; Head into steel pipe, bring line style steel member (reinforcing bar, steel strand etc.) and Grouting Pipe in the steel pipe into, extract steel pipe, slip casting forms soil nailing or anchor pole.In work progress, the soil body is produced compacted effect, the pore forming process hole that do not collapse, Grouting Pipe is not stopped up, and can carry out secondary grouting, easier ensuring the quality of products; Behind roof-bolter boring or the pore-forming, head into steel pipe, bring line style member (reinforcing bar, steel strand etc.) and Grouting Pipe in the steel pipe into, directly slip casting or extract the steel pipe grouting behind shaft or drift lining and form anchor pole; Solved anchor pole band steel strand and Grouting Pipe and twine the problem of boring in work progress, the assurance degree of depth and Grouting Pipe are not stopped up, and guarantee construction quality; Directly head into concrete prefabricated parts, form soil nailing or anchor pole, work progress is easy, cost is low.

Description of drawings

Fig. 1 is the utility model front view;

Fig. 2 directly is installed on crawler-mounted excavator position of bucket view for jack;

Fig. 3 is installed on special stand device systems view for jack.

The specific embodiment

Hydraulic ceiling coil pore-forming equipment, as shown in Figure 1, it comprises jack 1, stake point 2, steel pipe 3, the reinforcing bar 4 of packing in the steel pipe, steel strand 5 and Grouting Pipe 6 constitute combined member, and the tail end of jack and combined member is connected, stake point 2 is installed in the front portion of combined member, and the stake point adopts bayonet joint with combined member.Said jack 1 can be hollow punching jack or twin-tub, four cylinders interlock jack, jack can adopt jig or directly weld fulcrum on member with combined member and be connected, jack can directly be installed on the crawler-mounted excavator position of bucket as shown in Figure 2, also can be installed on the special stand device systems as shown in Figure 3.The using method of hydraulic ceiling coil pore-forming equipment is:

A heads into line style steel member (steel pipe, shaped steel or reinforcing bar etc.) and directly forms soil nailing or head into steel pipe grouting behind shaft or drift lining formation soil nailing;

B heads into steel pipe, brings line style steel member (reinforcing bar, steel strand etc.) and Grouting Pipe in the steel pipe into, extracts steel pipe, and slip casting forms soil nailing or anchor pole;

C after the roof-bolter Completion of Drilling Hole, heads into steel pipe, brings line style member and Grouting Pipe in the steel pipe into, directly slip casting or extract the steel pipe grouting behind shaft or drift lining and form anchor pole;

D directly heads into concrete prefabricated parts, forms soil nailing or anchor pole.
