A kind of prefabricated slab opposite tension vertical non-slope embankment and its construction method

Abstract

The invention relates to a prefabricated slab oppositely-pulling vertical type non-slope embankment and a construction method. Breast board pile foundations are arranged in a soil layer, strip-shaped cast-in-place bottom boards are arranged at the tops of the pile foundations, U-shaped cup openings are reserved in the strip-shaped cast-in-place bottom boards, and assembly type prefabricated breast boards are arranged in the U-shaped cup openings. Connecting rods are embedded in the assembly type prefabricated breast boards, fixing frames are welded to the connecting rods, replaceable planting grooves are formed in the fixing frames, planting soil is arranged in the replaceable planting grooves, and vegetation is planted on the planting soil. A cushion layer is arranged at the lower portion of embankment padding. The prefabricated slab oppositely-pulling stand type non-slope embankment has the following beneficial effects that firstly, land is reasonably used, and the manufacturing cost is reduced; secondly, the assembly type prefabricated breast boards are adopted on the two sides of the embankment for construction, and the construction schedule is accelerated; thirdly, when the embankment padding is used for filling, pull rods or pull ropes are adopted for tightening the assembly type prefabricated breast boards on the two sides, and the integrity of the embankment is guaranteed; and fourthly, various construction manners are provided, the embankment can adapt to construction under multiple different geological conditions or different working conditions, and the use range is wide.

Description

technical field [0001] The invention relates to a slope-free embankment and a construction method, in particular to a prefabricated slab-to-straight vertical slope-free embankment and a construction method, belonging to the field of roadbed engineering. Background technique [0002] At present, automobiles have become an indispensable means of transportation in human society, so they need the cooperation of infrastructure such as highways. Lightweight and heavy-duty automobiles are two major development trends. The former requires speed assurance and the latter requires carrying capacity, and expressways can just organically combine the two. With the rapid growth of the local economy, the density of the road network is increasing, and the demand for expressways is increasing. The design of expressway embankment is especially important for expressway construction. [0003] The traditional expressway embankment is mainly constructed in the form of grading, which occupies a la...

AI Technical Summary

Problems solved by technology

[0003] The traditional expressway embankment is mainly constructed in the form of grading, which occupies a large amount of non-renewable land resources. At the same time, slope protection measures must be taken, which has a great impact on houses and farmland along the expressway. At the same time, when the slope protection is not handled properly, disasters such as landslides will occur, which seriously threaten people's property and life safety. The short-term and long-term conditions of farmland cultivation, how to rationally design expressway embankments under the premise of ensuring farmland resources and people's interests, has an important role and significance in promoting the sound development of highway construction
