Construction method for arched framework revetment

Abstract

The invention discloses a construction method for an arched framework revetment. The construction method includes the following steps of (1) slope surface finishing; (2) measurement and laying-off, specifically, roadbed side lines and roadbed revetment foundation side lines are laid out according to an arched framework and with the control of the revetment central line, control pillars are arranged, and the outline of the multi-layer framework are drawn; (3) roadbed slope brushing, specifically, a side slope is finished according to gradient hanging lines, the slope surface capping mass and loss stones need to be cleared at the roadbed; (4) digging, specifically, an arched framework foundation groove is dug, and an arched framework formwork is installed and fixed in the dug foundation groove; (5) pouring, specifically, concrete is poured from a banket of the arched framework from bottom to top, and after pouring, surface finishing and flattening are carried out; (6) jointing, specifically, the two sides and bottom of a slope surface draining groove of the arched framework revetment are subjected to mortar sealing treatment; and (7) planting, specifically, grass is planed in the arched framework in a spray-seeding mode, and membrane curing is also conducted. The construction method for the arched framework revetment lowers the engineering coast and prevents water and soil loss while the slope surface protecting function is achieved.

Description

technical field [0001] The invention belongs to the technical field of highway construction, and in particular relates to a construction method for slope protection with an arched skeleton. Background technique [0002] During the construction of highways and railways (especially in mountainous areas), a large number of exposed slopes will be formed due to frequent high filling and deep excavation. Greatly destroyed the ecological environment along the surrounding area. Traditional slope protection technologies include masonry rubble, prefabricated concrete blocks, etc. These traditional slope protection technologies are time-consuming, labor-intensive, costly, and the effect of slope protection is not ideal, and the surrounding ecological environment is seriously damaged during the construction process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method for slope protection with arched skelet...
