Abstract

The invention relates to equipment and a method for constructing a high-pressure rotary jet stiffening pile by using a ribbed drilling method. The technical scheme is that: the equipment comprises an end bearing plate which is adjacent to a bearing; the bearing is provided with a protective cover; and a tapered propelling body is arranged on the non-bearing side of the end bearing plate. The equipment also comprises a vibroflot on one side, which is not provided with a drive drill pipe, of a power head. Due to the adoption of the technical scheme, the equipment and the method have the beneficial effects that the bearing is effectively protected; the protective cover is arranged outside the bearing, so that sand cannot enter the bearing; the sectional protective cover has a splicing surface which is a folding surface, and can be split through the splicing surface; the bearing can be replaced, and the sand and the like can be effectively prevented from entering the bearing through the folding surface; the tapered propelling body is arranged on the non-bearing side of the end bearing plate, so that obstacles on a propelling path can be effectively eliminated, and the end bearing plate can be smoothly propelled to finish construction; in addition, the vibroflot is arranged, so that the stratum on the propelling path can be effectively loosened, and the construction can be smoothly finished; and manpower and material resources are saved, work hours are reduced, complex procedures are eliminated, and pore-forming, rib insertion and grouting can be finished at one time.

Description

Technical field:

[0001] The invention relates to the field of civil engineering, in particular to construction equipment and a method for high-pressure rotary grouting stiffened piles by drilling with reinforcement. Background technique:

[0002] Anchorage technology first appeared in the development and construction of mines, and then matured in the construction of railways, highways and water conservancy. With the continuous development of underground space, anchoring technology has been widely used in the field of construction. At present, the anchoring technology is divided into weathered and broken rock anchoring and weak soil anchoring. Rock drilling equipment includes gas rock drills, gas lift down-the-hole drilling rigs and geological drilling rigs. Hole-forming equipment for soft soils includes helical bolt rigs, self-tapping screw bolt rigs (fixed directly with screws without grouting) and Luoyang shovels. Anchor reinforcements include ordinary steel bars, prest...

Embodiment Construction

[0048] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0049] An end bearing disc 13 is included which adjoins the bearing 6 which has a protective cover. Described bearing 6 has protective cover. The protective cover can effectively protect the bearing.

[0050] The further technical solution of the present invention is: the protective cover is divided into two parts that can be spliced, that is, the rear shell 4 of the bearing protective cover and the front shell 5 of the bearing protective cover. Dividing into two parts allows the inner bearing 6 to be replaced.

[0051] The further technical solution of the present invention is that: the splicing surface between the rear shell 4 of the bearing protection cover and the front shell 5 of the bearing protection cover is a folded surface. The folded surface can effectively prevent sand from entering the bear...
