Mechanical slotting method used in railway protection slope construction

Abstract

The invention discloses a mechanical slotting method used in railway protection slope construction. The mechanical slotting method used in the railway protection slope construction includes: S1, performing slope surface finishing: measuring a top line, a toe line and a platform position line of a side slope on the side face of a roadbed through a total station instrument; S2, performing hanging line layout: laying side edge lines of a start point and an end point of a framework and edge seal lines of the bottom and the top of the framework on the side slope, and marking the side edge lines andthe edge seal lines; S3, starting to excavate a base slot: excavating the base slot for placing the framework through a milling excavator; S4, performing base slot finishing: tamping the base slot through a tamping machine; S5, performing acceptance inspection on the base slot: performing the acceptance inspection according to acceptance standards of the base slot; S6, mounting the framework; S7, mounting a water drainage pipe; S8, pouring concrete; S9, setting acceptance inspection steps; S10, setting expansion joints. The mechanical slotting method used in the railway protection slope construction is a brand new base slot shaping method, reduces construction difficulty, improves overall construction efficiency, and simultaneously optimizes overall structure of a railway protection slope, and improves structural strength of the protection slope.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to a mechanical slotting method used in railway slope protection construction. Background technique [0002] The railway is a track line specially used for trains and other means of transportation. With the development of the national economy, my country's railway industry has also developed rapidly in the past ten years, and the total mileage of railway operation has exceeded 100,000 kilometers. At present, railways and infrastructure are the key areas of national investment. During the construction of railways, a good slope protection structure is an important factor to ensure the safe operation of trains. [0003] One of the links in the slope protection construction process is to use an excavator to dig out the foundation trench on the slope protection. The current construction method is to use the excavator to directly dig out the soil along the lime line, but beca...

Problems solved by technology

[0003] One of the links in the slope protection construction process is to use an excavator to dig out the foundation trench on the slope protection. The current construction method is to use the excavator to directly dig out the soil along the lime line, but because the arch skeleton is curved, the corresponding lime line is also formed. curved, and the bucket of an ordinary excavator cannot completely fit the curved white-gray line to dig out the foundation trench accurately. Regular, the soil at the edge of the foundation groove is easy to loosen, making the quality of the entire foundation groove very low
