Operation device related to digging pile mechanical hole forming and construction method of operation device

Abstract

The invention relates to the technical field of in place concrete pouring of piles or similar concrete piles, in particular to an operation device related to digging pile mechanical hole forming and a construction method of the operation device. A center operation platform comprises an upper steel plate, a lower steel plate, protective plates and channel-section steel which is arranged between the upper steel plate and the lower steel plate which are parallel. A screw penetrates through the upper steel plate, the lower steel plate and the channel-section steel and is fixed, and thus the center operation platform is formed. The center operation platform is square. The protective plates rotating round the edges axially are connected to the fours edges of the center operation platform correspondingly. The construction method of digging pile mechanical hole forming comprises the steps of point stake-out, fore shaft construction, rotary drilling rig drilling and hole forming, protective wall concrete construction after hole forming, reinforced banding and welding, sounding pipe machining and installing and pile core concrete filling. According to the operation device related to digging pile mechanical hole forming and the construction method of the operation device, the labor intensity of personnel can be relieved on the premise that the cost is not increased. Through a rotary drilling rig and a round drill bit, the operation efficiency is improved, the construction cost is reduced, and meanwhile, the safety of construction personnel is ensured.

Description

[technical field] [0001] The invention relates to the technical field of on-site pouring concrete or similar concrete piles, in particular to an operation device and a construction method for mechanically forming holes in hole-digging piles. [Background technique] [0002] With the vigorous development of railways and highways in the country, manual hole-digging piles are easier to construct, faster, and do not require large-scale mechanical equipment. The hole-digging piles have stronger earthquake resistance than wooden piles and concrete driven piles, and their cost is lower than that of punching cone punching. , Impact cone punching, percussion drilling rig punching, rotary drilling rig drilling, and caisson foundations are all low, so they are widely used. [0003] Manual hole-digging piles are basically transported vertically by small winches, the upper and lower spaces are small, and there are many operations near the hole, which endangers the lives of underground wor...

AI Technical Summary

Problems solved by technology

The existing artificial excavation piles are expensive to construct and are generally used in various complex geological conditions. However, due to the completion of the project quantity, the construction personnel often ignore the quality of the retaining wall, which brings great safety risks

The underground operation conditions of excavation piles are poor and the environment is harsh. Construction workers have been in a limited space with a high dust concentration for a long time, which seriously threatens the health of personnel and even brings serious occupational diseases.
