Problems solved by technology

[0006] In order to overcome the deficiencies of the existing technology, the present invention provides a hole forming speed, high positioning accuracy, convenient operation, low safety risk and wide applicability, which can greatly improve the construction efficiency, speed up the construction progress, accurate positioning, and solve the problem of manual digging. The construction progress of hole piles is slow and the risk is high, so it has a good market application prospect
[0007] Another object of the present invention is to achieve low construction cost, good hole-forming quality and high precision, and solve the problem of low efficiency of manual digging piles breaking into the rock, and blasting excavation is not allowed in complex environments, making hole-forming construction extremely difficult The big problem is that you only need to use the conventional rotary excavator mechanical equipment, but it will not only increase the construction cost, but also realize the maximum reduction of the labor intensity of the operator. Such an improved simple rectangular anti-sliding pile machine for rapid hole-forming construction method

Embodiment Construction

[0050] The specific implementation of the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] Taking the landslide prevention project as an example, the slope support structure is supported by a pile plate retaining wall, and the pile foundation is a rectangular anti-slide pile with a size of 1.5m×2.4m. Construction method see Figure 1 to Figure 6 As shown, the following steps are generally included:

[0052] A. Anti-slide pile hole setting out positioning

[0053] A.1 Determine the size of the rectangular pile hole contour line 1 as 1.5m×2.4m;

[0054] A.2 According to the length of the short side of the rectangular pile hole contour line 1 is D = 1.5m, the diameter of the hole formed by the medium-sized or large-scale rotary pile excavation machine on the market is 0.8-2.5m, and the diameter of the drill bit of the rotary pile excavation machine is determined to be d 1 =1.8m;

[0055] A.3 ...

Abstract

The invention discloses an improved simple and simple rectangular anti-sliding pile mechanical rapid hole-forming construction method, which specifically includes the steps: A. setting out and positioning the rectangular pile hole; B. making a rectangular steel casing; C. rotating the pile machine according to the pile core Excavate the hole with serial number and position; D. Use the hydraulic vibratory hammer to lower the rectangular steel casing into the rectangular pile hole to remove excess earthwork; E. Pour concrete in the over-excavation area outside the steel casing; F. Lift the steel casing with the hydraulic vibratory hammer ; G. Lower the rectangular steel cage and pour concrete to form anti-slide piles. The construction method of the invention solves the problems of slow construction progress and great difficulty in forming holes for manual hole-digging piles, and has the advantages of convenient operation, safe construction, high efficiency and wide applicability.

Description

technical field [0001] The invention relates to a hole-forming construction method of an anti-slide pile, in particular to a construction method for fast mechanical hole-forming of a rectangular anti-slide pile, and belongs to the technical field of slope support structure construction. Background technique [0002] As we all know, rectangular anti-slide piles usually adopt the construction method of manual digging. The construction operation method of the manual hole-digging pile is simple, the construction is convenient, and the construction quality is easy to guarantee. However, the underground operation conditions of excavated piles are poor, the environment is harsh, the labor intensity is high, the construction speed of single piles is slow, and the safety hazards in construction are also very prominent. The construction personnel must work underground, the personal safety problem is extremely serious, there are many unsafe factors and hidden dangers, and the construc...
