Problems solved by technology

[0002] In construction in permafrost areas, it is difficult for ordinary excavators to damage the structure of the permafrost layer during the excavation process. It can only be removed layer by layer after the top layer of frozen soil melts, and each layer is only limited to 20-30cm. After a long time, the permafrost on the slope melted unstable and collapsed
It is easy to collapse when it melts, and the construction is difficult
In winter construction, the quality is difficult to guarantee, and the construction cost in winter is high

Embodiment Construction

[0033] The excavation construction method of the assembled reinforced ripper in the plateau permafrost area of ​​the present invention is characterized in that the assembled reinforced ripper is assembled on the crawler excavator, which can be exchanged and used with the bucket, and the hydraulic pressure of the crawler excavator is utilized. The piston pushes the tooth seat of the ripper to change the excavation direction and operating point of the bucket hook of the ripper. The bucket hook 1 of the described ripper is in the shape of a single-tooth front end with a pointed mouth.

[0034] The excavation construction method of the assembled reinforced ripper in the permafrost region of the plateau is characterized in that the steps of the method are:

[0035] (1) The tool is assembled and formed; the choice of scarifier model should be in accordance with Choose the maximum power of the excavator and the weight of the adapted machine;

[0036] (2) Check the performance of ...

Abstract

The invention discloses an excavation construction method of an assembled reinforced scarifier for a plateau permafrost region. The method is characterized in that the assembled reinforced scarifier is assembled on a crawler excavator and can be exchanged with a bucket to be assembled and used; a hydraulic piston of the crawler excavator is utilized to push a tooth seat of the scarifier to change the excavation direction and a working point of a bucket hook of the scarifier, wherein the scarifier comprises a main board, a hanging lug plate, a rear plate, a bucket lug plate, a bucket lug sleeve, bucket teeth, the tooth seat, a protecting plate and other spare parts. Compared with a common excavator which is difficult to damage the structure of the permafrost layer during excavating and can remove the permafrost by layers only after the permafrost in the top layer is molten, each layer of the permafrost is limited to be damaged between 20 and 30cm, and collapse easily occurs due to the unstable melting of the permafrost on a side slope after the damaging work is performed for a longer term, the assembled reinforced scarifier is out of the limitation on the frosting degree and thickness and the like of the permafrost layer, and each layer of the permafrost can be damaged about 50cm in thickness, so that the work of breaking the permafrost layer can be finished within a short time, and as a result, the construction progress can be increased, and the construction period can be saved.

Description

technical field [0001] The invention relates to frozen soil construction technology, in particular to an excavation construction method of an assembled reinforced ripper in a plateau frozen soil area. Background technique [0002] In construction in permafrost areas, it is difficult for ordinary excavators to damage the structure of the permafrost layer during the excavation process. It can only be removed layer by layer after the top layer of frozen soil melts, and each layer is only limited to 20-30cm. After a little longer time, the slope permafrost melted unstable and landslides occurred. It is easy to collapse when melted, and the construction is difficult. In winter construction, the quality is difficult to guarantee, and the construction cost in winter is high. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides an excavation construction method of an assembled reinforced ripper ...
