Description

Counterfort formula barricade of counterfort board grid ization

Technical Field

The utility model belongs to the technical field of building side slope protection engineering, a counterfort formula barricade that counterfort board trellis is constructed is related to.

Background

The retaining wall is a structure for solving the topographic height difference and preventing the soil mass at the topographic height difference from collapsing, and is widely applied to house buildings, railways, roads, water conservancy and bridge engineering. Common retaining walls include reinforced earth retaining walls, gravity retaining walls, pile-slab retaining walls, cantilever retaining walls, and buttress retaining walls. The cantilever type retaining wall and the counterfort type retaining wall are light supporting and retaining structures, and are small in thickness and light in dead weight. Cantilever type barricade and buttress formula barricade all rely on the dead weight of barricade self and the weight of the fill soil body above the wall heel board to maintain the stability of barricade. The cantilever type retaining wall and the counterfort type retaining wall have large basal area, low requirement on bearing capacity of the foundation and good economic index when the retaining wall is higher. Thus, cantilevered and buttress walls are often the preferred form of construction for backfilled slope designs.

The unit width of structural members such as vertical plates, toe plates and heel plates of the cantilever type retaining wall can be designed and calculated according to the cantilever plate member. The retaining height of the cantilever type retaining wall is not more than 6m, otherwise, the vertical plate of the cantilever type retaining wall generates large deformation, and the requirements of normal use and bearing capacity limit state of the slope design cannot be met.

On the basis of the cantilever type retaining wall, a buttress plate is arranged at certain intervals along the longitudinal direction of the wall, so that the conventional buttress type retaining wall is formed. The vertical plate and the wall heel plate can be designed according to boundary constraint conditions according to a plate with three fixed edges and one free edge or a continuous plate taking a buttress plate as a support; the toe board of the wall can be designed according to the cantilever board fixed on the vertical board; the buttress plate can be simplified into a T-shaped cantilever beam for design. The counterfort retaining wall is through setting up the counterfort, converts the atress characteristics of riser into the component of encorbelmenting by the component of encorbelmenting, and the atress form is better, warp and cross-sectional dimension better control, can be applicable to bigger retaining height than the cantilever type retaining wall. However, the conventional buttress retaining wall has more dead angles due to the existence of the buttress plate, which is not beneficial to filling and compacting the back of the retaining wall and is not beneficial to maintaining the stable stress characteristic of the retaining wall by soil filling and self weight. In addition, pipelines are usually laid in the retaining wall filling soil along the retaining wall in the engineering, but the construction is difficult due to the existence of the wall supporting plate, so that the engineering cost and the construction difficulty are greatly increased, and the application range and the economical efficiency of the wall supporting type retaining wall are reduced.
