Construction method of pile precast slab retaining wall with drainage ditch

Abstract

The invention discloses a construction method of a pile precast slab retaining wall with a drainage ditch. The construction method comprises the following steps that firstly, wall corners are cleaned, unwinding and point distributing are performed and pile hole excavation is performed; secondly, an underground pile reinforcement cage is manufactured; thirdly, an underground pile is poured; fourthly, a ground beam reinforcement cage is manufactured; fifthly, a ground pile reinforcement cage is manufactured, sixthly, a ground beam is poured; seventhly, a ground pile is poured; eighthly, the drainage ditch 4 is poured; ninthly, a precast slab and a drainage pipe are installed. The pile precast slab retaining wall with the drainage ditch is reasonable in structure, easy to construct, fast and safe in construction, less in consumed materials and low in cost. When the retaining wall is built, the drainage ditch is built, in addition, the drainage ditch is integrated with a wall body, and a ditch body has the function of strongly supporting the retaining wall.

Description

technical field [0001] The invention relates to the technical field of retaining walls, in particular to a construction method for a pile prefabricated plate retaining wall with drainage ditches, which is suitable for communication and identification between ships. Background technique [0002] A retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the deformation and instability of fill or soil. Retaining walls are widely used in the soil protection of various building foundations, such as agricultural facility construction, road side slopes, sites and buildings around, and embankment slope protection. According to the structure, the current retaining wall can be divided into: gravity retaining wall, anchor retaining wall, thin wall retaining wall, reinforced soil retaining wall, column plate retaining wall, pile plate retaining wall and frame type retaining wall, etc.; except for the gravity type retaining wall, which is built of r...

AI Technical Summary

Problems solved by technology

[0003] The rubble gravity retaining wall has a long history in our country, but its existing problem is that it has high requirements for the foundation of the wall, usually a deep foundation needs to be excavated, and the foundation is required to be wide, and the width of the foundation construction surface usually reaches 1.2-1.5 meters, and the width of the upper part of the wall is also 0.8-1 meters, which results in a large amount of engineering, slow construction speed, and high cost; at the same time, a large amount of rough stone needs to be mined, causing serious damage to the ecological environment of the mountain

However, some reinforced concrete retaining walls are relatively complex in structure and troublesome in construction, and some are relatively expensive, so this type of retaining wall is rarely popularized and applied in practice.
