Culvert opening closing structure suitable for highly-filled steep slope section and construction method of culvert opening closing structure

Abstract

The embodiment of the invention relates to the field of geotechnical engineering, and provides a culvert opening closing structure suitable for a highly-filled steep slope section and a construction method of the culvert opening closing structure. The structure comprises culvert side walls arranged at the two ends of a culvert opening, a culvert opening top plate, anti-slide piles and other structural components, and the two anti-slide piles are closely vertically attached to the side walls of the two sides of the culvert opening correspondingly. Steel reinforcement cages which are verticallyarranged are arranged in the anti-slide piles. Longitudinal steel bars are arranged in the culvert side walls. The steel reinforcement cages and the adjacent sections of the culvert mouth side wall longitudinal steel bars are connected into a whole. According to the culvert structure provided by the invention, the anti-slide piles in the pile plate type retaining wall are arranged at the end partsof the culvert side walls, and the steel reinforcement cages in the anti-slide piles are connected with the longitudinal steel bars in the culvert side walls, so that the anti-slide piles and the culvert side walls are fixedly combined into a stressed whole, the lateral restraint capacity of the cantilever ends of the anti-slide piles is improved, and then the slope closing capacity of the pile plate type retaining wall in a highly-filled steep slope section is improved; and meanwhile, the drainage effect of the highly-filled steep slope section is also ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of geotechnical engineering, and in particular to a culvert closure structure suitable for high-fill steep slope sections and a construction method thereof. Background technique [0002] When railway and highway projects pass through high-fill and steep slopes, the subgrade engineering often needs to be equipped with pile-slab retaining walls to play the role of support and slope closure, meet the anti-sliding stability requirements of the subgrade engineering, avoid the existence of high-fill subgrades on slopes, and reduce or eliminate Project hidden dangers; at the same time, in order to meet the requirements of flood drainage, irrigation and transportation, culvert works must be set up within the lot area at the same time. However, conflicts often occur due to the difficulty in connecting the pile-slab retaining wall with the culvert. In previous designs, only one of the two cou...
