Problems solved by technology

However, for some road sections located on high and steep slopes in the mountains, where vertical protection is required on both sides and the protection height is high, the traditional pile-slab wall cannot meet the vertical protection height because the cantilever can not exceed 15m. requirements

Embodiment

[0042] like figure 1 , figure 2 As shown, the embodiment of the first aspect of the present application provides a pile-slab wall structure 100. The pile-slab wall structure 100 includes a plurality of anti-sliding pile structural units 10 and soil retaining panels 20 arranged at intervals along the front-back direction A. Each anti-slide pile structural unit 10 includes a beam 12 and two anti-slide piles 11 arranged at intervals along the left-right direction B, and the two anti-slide piles 11 are connected by the beam 12 . Every two adjacent anti-slide piles 11 in the front-rear direction A are connected by at least one soil retaining plate 20 . All the anti-slide piles 11 and the earth retaining board 20 jointly define the filling space 30 filled with the reinforced soil subgrade 200 . The two anti-slide piles 11 facing each other in the left-right direction B are connected by a beam 12 , which can ensure the relative stability of the two anti-slide piles 11 . In some spe...

Abstract

The invention provides a sheet-pile wall structure and a roadbed structure, and relates to the field of civil engineering. The sheet-pile wall structure comprises a plurality of anti-slide pile structure units and breast boards which are arranged at intervals in the front-back direction. Each anti-slide pile structure unit comprises a cross beam and two anti-slide piles arranged at intervals in the left-right direction, and the two anti-slide piles are connected through the cross beam. Every two adjacent anti-slide piles in the front-back direction are connected through at least one breast board. And all the anti-slide piles and the breast boards jointly define a filling space for filling the reinforced soil roadbed. The two opposite anti-slide piles in the left-right direction are connected through the cross beam, and the relative stability of the two anti-slide piles can be guaranteed. In some special terrains, the vertical length of the overground part of the sheet-pile wall needs to be increased, the cross beam can guarantee the stability of the cantilever part, the situation that the overground part of the anti-slide pile shakes due to the fact that the cantilever is too longis avoided, and the sheet-pile wall structure can meet the use requirements of some situations with higher requirements for the vertical protection height.

Description

technical field [0001] The present application relates to the field of civil engineering, in particular to a pile-slab wall structure and a roadbed structure. Background technique [0002] As a preventive road safety facility, the avoidance lane generally adopts the form of roadbed and is mainly set on the dangerous section of the highway to reduce accidents such as rollovers caused by vehicles out of control. The setting of the avoidance lane has saved countless lives. With the development of highway construction in mountainous areas, pile-slab wall technology is widely used in slope retaining engineering, which can adapt to complex terrain to a large extent. However, for some road sections located on high and steep slopes in the mountains, where vertical protection is required on both sides and the protection height is high, the traditional pile-slab wall cannot meet the vertical protection height because the cantilever can not exceed 15m. requirements.
