Abstract
A hydraulic jacking pipe perforation process is provided, which comprises: (a) pushing a linear steel member or pushing a steep pipe in the soil and grouting to form a soil nail; (b) pushing a steel pipe with a linear steel member and a grouting pipe inside in the soil, pulling out the steel tube, grouting to form a soil nail or anchored bar; (c) drilling by a bolter, pushing the steel pipe into the drilled hole, grouting directly or after pulling out the steel pipe to form anchored bar; (d) directly pushing a pre-cast concrete member to form a sole nail or anchored bar. The invention has the advantages of simple construction, low cost, no collapse during perforation, no blockage of grouting pipe, suitability for secondary grouting, and high quality. The anchored bar is formed directly by grouting or after pulling steep pipe, so as to solve the problems that the anchored bar has stranded wire and the grouting pipe enwinds the drill. The pre-cast concrete member is directly pushed to form the soil nail or anchored bar. The invention is widely used for direct drilling in soil layer or insertion of linear steel member and grouting pipe in soil in earth retention or foundation pit support.
Description
Technical field
The present invention 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 invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of hydraulic ceiling coil pore-forming technique and equipment are provided, this hydraulic ceiling coil pore-forming technique directly heads into steel pipe etc. in the soil layer, job practices is simplified, guarantee construction quality more reliably, raise the efficiency, thereby reduce cost.Hydraulic ceiling coil pore-forming technique comprises the steps:
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.
The equipment that provides a kind of above-mentioned hydraulic ceiling coil pore-forming technique to adopt is provided, it comprises jack, the stake point, steel pipe, reinforcing bar, steel strand, shaped steel and the Grouting Pipe of packing in the steel pipe constitutes combined member, the tail end of jack and combined member is connected, and the stake point is installed in the front portion of combined member, and the stake point adopts bayonet joint with combined member.
Adopt Processes and apparatus of the present invention, steel pipe etc. is directly headed in the soil layer, job practices is simplified, 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.
