Embodiment Construction

[0011] Such as figure 1 As shown, a double-row sheet pile wall revetment structure suitable for deep soft soil foundations consists of front and rear row sheet pile walls 1 and 2, and cast-in-place concrete bearings connecting the upper parts of front and rear row sheet pile walls 1 and 2 The cast-in-place concrete cap 3 is erected on the front and rear row of sheet pile walls 1 and 2, and the joints are connected by cast-in-place, wherein the front and rear row of sheet pile walls 1 and 2 are all made of row piles, prefabricated The front and rear row of sheet pile walls 1 and 2 are two rows, and there is a soil reinforcement 5 between the front and rear row of sheet pile walls 1 and 2, thus forming a semi-gravity cylinder Warehouse structure; the soil reinforcement 5 is formed by treating the soil between the front and rear row sheet pile walls 1 and 2 with jet jet pile foundation treatment, and of course there are other methods that can achieve this effect, which will not b...

Abstract

The invention discloses a double-row plate pile wall revetment structure suitable for a deep and thick soft soil foundation. The double-row plate pile wall revetment structure suitable for the deep and thick soft soil foundation is mainly composed of a front row plate pile wall, a rear row plate pile wall and an upper cast-in-place concrete bearing platform connecting the front row plate pile wall with the rear row plate pile wall. Each of the front row plate pile wall and the rear row plate pile wall can be formed by connecting row piles, prefabricated plate piles or a diaphragm wall. Foundation treatment is conducted on a soil body between the front row plate pile wall and the rear row plate pile wall through rotary jet grouting piles and the like, and a half-gravity type silo structure is formed. According to the double-row plate pile wall revetment structure, earth excavation in a narrow area is avoided, the double-row plate pile wall revetment structure is suitable for poor deep and thick soft soil geological conditions, can bear high backfill pressure behind the plate piles and meets the requirement for overall stability; the structure reliability is high, the effect of control over horizontal displacement of a revetment is good, and the application prospects are wide; and the double-row plate pile wall revetment structure is particularly suitable for the deep and thick soft soil foundation, the region with the large front edge water depth, the region with the narrow construction field, the region with the complex surrounding environment and other regions.

Description

technical field [0001] The invention relates to revetments in water conservancy and waterway engineering, in particular to a revetment structure with double-row sheet pile walls, which can be adapted to deep and thick soft soil foundations. Background technique [0002] As an important part of water-land connection, revetments are widely used in water conservancy and water transportation projects. In recent years, with the development of sponge cities and coastal cities, more and more projects require new revetments in urban rivers and urban coastal areas. Newly built revetments are often limited by frontal water depth, geological conditions, construction sites, and surrounding environments. At present, pile-based reinforced concrete buttress structures or anchor-drawn sheet pile structures are commonly used for revetment structures on deep soft soil foundations. For newly-built revetments close to the sea or rivers, if pile-based reinforced concrete buttress structures are ...
