A kind of cast-in-place construction technology of anti-slide pile inter-pile slab wall

Abstract

The invention discloses a cast-in-place construction process for an inter-pile board wall between slide-resistant piles. The inter-pile board wall to be constructed is located between the two adjacent slide-resistant piles. The process includes the steps that firstly, construction surveying is performed; secondly, construction of the slide-resistant piles is performed, wherein the two slide-resistant piles are constructed respectively; thirdly, excavation of inter-pile soil is performed, wherein the soil between the two slide-resistant piles is excavated in multiple layers from top to bottom; fourthly, an inverted filter is stacked on the rear side of the inter-pile board wall to be constructed; fifthly, cast-in-place construction of the inter-pile board wall is performed, wherein a steel reinforcement framework formed by splicing multiple steel reinforcement cages from bottom to top is arranged in the inter-pile board wall to be constructed, multiple drainage hole reserved tubes are arranged in each steel reinforcement cage, and the construction process of the inter-pile board wall to be constructed includes the steps of steel reinforcement framework binding, drainage hole reserved tube laying, formwork erection and concrete pouring. The steps of the process are simple, and the process is reasonable in design, convenient to implement, high in construction efficiency, good in construction effect and capable of solving various problems existing in an existing cast-in-place construction method for the inter-pile board wall between the slide-resistant piles.

Description

technical field [0001] The invention belongs to the technical field of anti-sliding pile construction, and in particular relates to a cast-in-place construction process of a slab wall between anti-sliding piles. Background technique [0002] The slab wall between anti-slide piles refers to the pile-slab wall arranged between two adjacent anti-slide piles, and is generally located between two adjacent anti-slide piles among a plurality of anti-slide piles arranged at equal intervals. In recent years, the application of anti-slide pile slab walls in subgrade engineering has become more and more frequent, especially in the construction of high cutting and high filling subgrades, and has been widely used. The traditional anti-slide pile slab wall construction method is the prefabricated assembly method. The constructed anti-slide pile slab wall is composed of multiple pile slabs arranged from bottom to top, and the pile slab is a prefabricated soil retaining board. During actua...
