Abstract

The invention relates to a construction method for slope protection with a concrete arched skeleton, comprising the steps of: 1) construction preparation; 2) preparation of prefabricated components; 3) preparation of an integrated skeleton formwork; 4) excavation of skeleton laying grooves; 5) construction of edge connecting beams; 6) ) Sliding hoisting structure installation; 7) Prefabricated arched skeleton slope protection construction; 8) Prefabricated step installation; 9) Cast-in-situ arched skeleton slope protection construction. The beneficial effects of the present invention are: the present invention is respectively between the first straight mold and the second straight mold of the integrated skeleton template, between the third straight mold and the fourth straight mold, and between the first arc mold and the second arc mold. The mold top cover plate is set between the middle, the third arc mold and the fourth arc mold, which can simultaneously meet the functions of concrete pouring and integrated skeleton formwork reinforcement; guide sides are respectively set on both sides of the fourth straight mold of the integrated skeleton formwork The board can reduce the difficulty of installing and positioning the integrated skeleton formwork.

Description

technical field [0001] The invention relates to a construction method for slope protection with a concrete arched skeleton, which belongs to the field of roadbed protection and is suitable for the construction of highway roadbed slope protection engineering. Background technique [0002] The protection of subgrade slope support is an important measure to improve the stability of subgrade, and arched skeleton slope protection is a common form of protection. During the construction of arched skeleton slope protection, there are often problems such as poor control of appearance size and stability, difficulty in controlling the integrity of the skeleton, and low efficiency of on-site construction. [0003] In the prior art, there is a construction method of arched skeleton slope protection technology of subgrade slope, which is characterized in that: the foundation groove is excavated manually with skeleton slotting machine; the skeleton template is assembled with shaped steel m...
