Abstract

The invention relates to the technical field of slope support construction methods, and discloses a combined slope support construction method. The steps are as follows: 1), leveling treatment; 2), pouring drill holes to form pile bodies; 3), construction between piles The board between piles is vertically arranged, and the board between piles and the pile body are in a fixed arrangement; 4) The pile body and the slope form a multi-layer filling space, and the rolling soil is backfilled in the filling space many times to form a multi-layer rolling Soil layer; 5), after backfilling the rolling soil each time, construct unloading slabs; 6), construct blind ditch above each layer of unloading slabs, one end of the blind ditch is fixedly arranged, and the other end of the blind ditch extends The water outlets are respectively formed through the pile body and the inter-pile slab. In this way, the earth pressure distribution of the support structure is adjusted, the self-weight of the support structure is increased, the overturning stability is improved, and the support limit of the support structure is improved. Effectively control the deformation of the slope within the normal service life to ensure the safety of the project.

Description

technical field [0001] The patent of the present invention relates to the technical field of slope support construction methods, in particular, to a combined slope support construction method. Background technique [0002] When planning buildings on a mountain, if the planned site elevation is higher than the current terrain, the filling slope needs to be treated, and cantilever retaining walls, pile foundations + buttress retaining walls, unloading sheet pile sheet walls are often used As a retaining structure, the unloading sheet pile sheet wall is composed of an unloading sheet + anti-slide pile, which is often suitable for the treatment of fill slopes with a support depth of less than 10m. [0003] Conventional unloaded sheet pile-slab walls are mainly composed of excavated piles, unloaded plates, and inter-pile plates. Generally, only one unloaded plate is provided, and the backfilled soil is pressed against the unloaded plate to provide reverse pressure, thus compared ...
