Problems solved by technology

[0011] (1) Poor underground operating conditions, harsh environment, and high labor intensity;
[0012] (2) The safety is poor, and personnel work up and down in the hole, which is prone to casualties;
[0013] (3) The construction speed of single pile is relatively slow;
[0014] (4), the amount of concrete pouring is large
[0015] Of course, manual excavation piles are only limited to the soil formations in the plains. For the Sichuan-Tibet Interconnection Project with high altitude, harsh climate and terrain, and short construction time, conventional excavation equipment and construction methods cannot meet the construction needs.
[0016] The Sichuan-Tibet interconnection project starts from the Sichuan 500kV rural-urban substation, passes through the 500kV Batang substation, the Tibet 500kV Qamdo substation, and ends at the 220kV Bangda substation and Yulong substation. A new 500kV line is 1,036 kilometers long. The newly built 220 kV line is 505 km long and the 110 kV double-circuit line on the same tower is 2 × 9 km long. Most of the areas along the project line are in low pressure, anoxic, severe cold, strong wind, strong radiation and other areas, and the natural environment and climate conditions are extremely It is harsh and human construction is limited; at the same time, the project is located in the "Three Rivers" fault zone with the most complex geological structure and the widest distribution of geological disasters in the world. Functional role is difficult to play, construction is extremely difficult

Abstract

The invention relates to a drilling, excavating and soil lifting device of plateau mountain land foundation pit excavation construction equipment. The drilling, excavating and soil lifting device comprises a support framework, wherein a support frame is arranged on the support framework; two slideway frames are vertically arranged on the support frame; an ascending and descending bracket is arranged between the upper ends of the two slideway frames; a slideway is vertically arranged in each slideway frame; a doubling transmission mechanism is arranged on the slideway frames; a rotation driving device connected with the doubling transmission mechanism is glidingly arranged in the slideways; the power output end of the rotation driving device is connected with a drilling mechanism; and the lower end of the drilling mechanism is provided with an excavating mechanism and a soil lifting mechanism. The drilling, excavating and soil lifting device has the advantages that the design is reasonable; the automation degree is high; the work intensity of workers is sufficiently reduced; the safety degree and the reliability degree are high; the work efficiency of pile hole digging is improved; according to a line project pile hole digging foundation type, the study on plateau mountain land electric transmission line special basic foundation pit mechanization operation machine tools is developed, so that the technical requirements of line construction hole pile foundation digging are met; and the construction mechanization degree and the construction efficiency of an alternating current transmission line project are improved.

Description

Technical field [0001] The invention belongs to the technical field of construction in the electric power industry, and particularly relates to a drilling, digging, and soil lifting device for excavating construction equipment for plateau mountain foundation pits. Background technique [0002] The hole-digging pile foundation is a basic type commonly used in transmission line projects. Compared with the large-excavation foundation form, it has significant advantages in environmental protection, concrete maintenance, reducing backfill operations, and making full use of the performance of undisturbed soil. It is more and more widely used in line engineering. [0003] The traditional method of excavating the foundation pit is manual. The manual digging pile is a kind of pile type in which the pile hole is dug manually, and a steel cage is placed in the hole and concrete is poured. Its advantages are: [0004] (1) The manual digging pile construction equipment is simple, the constructio...
