Embodiment Construction

[0037] Attached to the following Figure 1-3 This application will be described in further detail.

[0038]The embodiment of the present application discloses a method for forming a pile with a screw-extruded soil to form a hole and a fixed sleeve followed by a poured concrete. refer to figure 1 and figure 2 , the screw extruding soil to form a hole and the fixed sleeve to follow up the pouring concrete pile method includes the following steps:

[0039] S1. Install two sets of soil extruding power heads 1 on the screw extruding soil pile machine. The two sets of soil extruding power heads 1 are respectively the first power head 11 and the second power head 12. The first power head 11 is cylindrical, and the second power head 11 is cylindrical. The power head 12 is cylindrical, the second power head 12 is sleeved on the outer side of the first power head 11 , and the lower ends of the first power head 11 and the second power head 12 are equipped with a soil extruding bit 13...

Abstract

The invention discloses a pile-forming method for screw-squeezing soil-forming holes and fixing sleeves followed by pouring concrete. A fixed sleeve is sheathed and detachably connected to the outer side; S3, start the first power head, make the first power head rotate downwards and drill into the hole, and then the second power head drives the fixed sleeve to drill down together Enter into the hole; S4, make a reinforcement cage, and fix the concrete cushion block at the lower end of the reinforcement cage; S5, disassemble and separate the fixing sleeve from the second power head, and then remove the first power head and the second power head from the fixed Take out the sleeve, and then embed the concrete block and the reinforcement cage into the fixed sleeve; S6, pump concrete to the inside of the fixed sleeve; S7, move the screw soil squeezing pile machine to the next pile position for construction. The reinforcement cage can be accurately guaranteed to be installed in the center during installation, so that the poured reinforcement cage structure is more stable.

Description

technical field [0001] The invention relates to the field of screw extruding soil pouring concrete to form piles, in particular to a method of screw extruding soil to form holes and fixing sleeves to follow up pouring concrete piles. Background technique [0002] At present, the screw extruded soil pile includes the general name of the two-way screw extruded soil pile and the screw pile. The screw extruding soil pile is a construction process in which the high-torque power head drives the drilling tool to rotate the soil or semi-extrude the soil to form a hole and press the concrete, and then insert the steel cage to form the pile. The advantages of this construction process are: high bearing capacity of a single pile, which can save a lot of building materials, fast construction speed, saving construction period, squeezed soil piles, no mud, and very little amount of muck discharged, which is more environmentally friendly. [0003] For example, the Chinese patent with the ...
