Description

Waist-beam-free supporting structure for rapid construction of pile-anchor supporting structure and construction method thereof

Technical Field

The invention relates to a waist-beam-free supporting structure for quick construction of a pile-anchor supporting structure and a construction method thereof, belonging to the technical field of building construction.

Background

The pile-anchor supporting technology is widely applied to projects such as foundation pit supporting, side slope supporting and the like. The main components of the anchor pile are a support pile, a waist beam and an anchor cable. The force transmission path is that the soil body pushes the support pile to deform, the support pile props against the waist beam to drive the waist beam to pull the anchor cable, and the anchor cable provides anti-pulling force by virtue of the bonding effect of the grouting body and the rock-soil body, so that the safety and stability of the whole support system are maintained.

The waist beam for supporting the pile anchor is a main transfer component, and the commonly used waist beams are reinforced concrete waist beams and profile steel waist beams. However, the concrete waist beam has heavy self weight, the binding construction of the steel bars and the templates is complicated, and the concrete curing time is long, so that the construction period is long; the construction position deviation of the supporting piles of the section steel waist beam causes that the free faces of the supporting piles cannot be consistent, so that the separation phenomenon of part of the supporting piles and the section steel waist beam is caused, normal force transmission cannot be realized, and potential safety hazards exist; meanwhile, the waist beam occupies a larger space, and the clear distance between the outer wall of the basement of the foundation pit and the support pile is required to be larger, so that the earth excavation amount is greatly increased, and the manufacturing cost is greatly increased; therefore, the pile-anchor supporting structure without the waist beam is produced at the same time.

The existing pile-anchor support without a waist-beam structure, such as a waist-beam-free anchor rod or anchor cable support structure disclosed in Chinese patent with publication number CN208949879U, is authorized as follows: 2019.06.07, respectively; the anchor pile comprises at least one retaining pile group, at least two anchoring bodies, an even number of anchor rods or anchor cables and limiting rings with the number equal to that of the anchoring bodies; the fender pile group comprises at least one fender pile; the first end of the anchoring body is fixed on a fixing surface, and the anchoring body is arranged on two sides of each enclosure pile group; the limiting ring is fixed at the second end of the anchoring body, the anchor rod or the anchor cable penetrates through the limiting ring, and the first end of the anchor rod or the anchor cable is fixed in the anchoring body; and the anchor rods or the anchor cables on the adjacent sides of the two anchoring bodies are respectively fixed on one side of the enclosure pile group far away from the fixing surface from the two sides of the enclosure pile group between the two anchoring bodies in a surrounding manner. Although the scheme provided by the patent of the girderless anchor rod or anchor cable supporting structure can realize the girderless structure supported by the pile anchor, the purposes of accelerating the construction speed of earth excavation, reducing the construction risk and finally shortening the construction period and reducing the manufacturing cost are achieved. However, in the scheme that this patent provided, need a support of construction on the fender pile, because the fender pile generally is reinforced concrete pile, the support needs the bar planting construction, leads to bar planting intensity maintenance to take time, and not only the construction is loaded down with trivial details, still occupies the time limit for a project, and consequently, this technique application degree of difficulty is great.

Accordingly, the present inventors have made extensive studies to solve the above problems and have made the present invention.
