Prestressed anchor cable pile sliding wall along river road shoulder and construction method thereof

Abstract

The invention discloses a prestressed anchor cable pile sliding wall along a river road shoulder and a construction method thereof, which relate to a high-filling retaining structure in construction fields of mountain roads and railway engineering, and comprise a circular pile, a coupling beam, T-shaped columns, retaining plates, anchor cables and anchor piers, wherein the circular pile, the coupling beam and the T-shaped columns are sequentially connected from the bottom up, the retaining plate is put at the inner side of each T-shaped column, an upper anchor pier, a middle anchor pier and a lower anchor pier are respectively arranged on the T-shaped column from top to bottom, the three fixed sections of an upper anchor cable, a middle anchor cable and a lower anchor cable are respectively anchored into a rock-soil layer, after the anchor cables pass through prepared holes of the T-shaped columns, the anchor cables are stretched and locked on the corresponding anchor piers, the inclination angles of the upper anchor cable, and the middle anchor cable and the lower anchor cable are designed to be 15 degrees, 18 degrees and 21 degrees. The invention has rational structure, easy implementation and good quality and is applicable to the construction of prestressed anchor cable pile sliding wall along the river road shoulder.

Description

technical field [0001] The invention relates to a high-fill retaining structure in the field of road and railway engineering construction in mountainous areas, in particular to a prestressed anchor cable pile-slab wall along a road shoulder along a river and a construction method thereof. technical background [0002] In the current highway and railway construction, the retaining structure of the high fill road section of some projects adopts the anchor cable pile sheet wall. The anchor cable pile-slab wall is suitable for filling subgrades with a filling height of 12-20m. It is smaller than ordinary retaining walls, has a reasonable structure, and is lower in cost than bridges. It is a flexible and light retaining structure. In order to facilitate the tension and loading of the anchor cable on the pile body, the pile body of the anchor cable pile sheet wall structure usually adopts the form of a square pile, and the hole is formed by manual digging. [0003] At present, th...

Problems solved by technology

[0006] The invention improves the structure of the general anchor cable pile-slab wall for the situation that the underground water level of the Yanhe road base is relatively high and it is extremely difficult to artificially form pile holes.
