Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing:

[0027] The construction technology of this whirling jet anchor pile comprises the following steps:

[0028] 1) Positioning, align the hollow anchor tube with the hole position;

[0029] 2) Drilling, use the anchor rod construction equipment to drive the anchor pipe to drill into the soil;

[0030] 3) Grouting, while drilling, grouting equipment is used to spray grout to the soil through the anchor pipe;

[0031] 4) After the pile is formed, the construction equipment is separated from the anchor pipe, and locked and sealed.

[0032] When drilling, by controlling the drilling speed, the rotating speed of the drilling rig in the construction equipment and the grouting pressure, the diameters of the sections of the swirling jet anchor pile 2 are different. At the large diameter of the anchor pile 2, the drilling speed is 1-70 cm / min, the drilling rig speed is 2-15 rpm, and ...

Abstract

The invention discloses a construction technology of reelingly stirring to eject an anchor tube pile, comprising the following steps: 1) positioning: aligning a hollow anchor pipe to a required hole site; 2) drilling: driving the anchor pipe to drill in soil with anchor rod construction equipment; 3) grouting: drilling while ejecting cement slurry to the soil through the anchor pipe with grouting equipment; 4) pile-forming: separating the construction equipment from the anchor pipe after forming the anchor pipe pile for reelingly stirring to eject, and locking a shell cover. The beneficial effects of construction technology are as follows: 1) using the anchor rod construction technology and the grouting technology to simultaneously work, constructing to reelingly stir to eject the anchor pipe in non rock soil of various simple and complex geological conditions, thereby effectively overcoming defects of difficult pore-forming and easy hole collapse of traditional anchor in soft soil layer when constructing, and the like; 2) simultaneously performing to reelingly stir to eject the anchor pipe and the grouting technology, no need dado, disposable pile-forming, thereby greatly simplifying the construction technology, quickening the construction speed and reducing the engineering cost.

Description

technical field [0001] The invention relates to a support technology for soil excavation and side slope stability, in particular to a construction technology for swirling jet anchor piles. Background technique [0002] At present, soil bolt support is widely used in foundation pit support engineering and slope stability engineering. The common construction method of soil bolt support is to drill holes first, then insert metal materials, and then grout. This construction technique not only has a long construction period, but also forms an anchor pile with a small diameter and low pullout resistance. In order to meet the requirements of engineering design, two methods are often used: 1. To increase the bearing capacity of a single anchor: increase the length of the anchor, secondary grouting, pile end expansion or prestressing, etc.; 2. Increase the density of the anchor. [0003] When using the first method, there are disadvantages such as complex construction technology, s...
