Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0030] Such as figure 1 Shown, lay drainage cushion 2 earlier, set plastic drainage board 1 then, to break through soft soil layer 21 and be advisable. Then layered flushing bagged sand quilt 3, such as figure 1 and image 3 As shown, after each layer of bagged sand is flushed and poured, the reinforcing belt 5 is laid and the sand is surrounded by the backfill 23 side, and initially tightened. The plastic drainage board 1 and the drainage cushion 2 together form a drainage system, which can accelerate the consolidation of the soft soil, and the bagged sand quilt 3 forms a loading system, which preloads the soft soil and gradually completes the settlement during the construction of the cofferdam.

[0031] After the cofferdam is formed, the anti-filter geotextile 14 is laid behind, and then the rear backfill soil 23 is con...

Abstract

The invention discloses a reinforced soil bank wall structure suitable for beach zone soft soil foundation conditions, namely a reinforced soil bank wall structure based on a beach soft foundation. The reinforced soil bank wall structure comprises plastic drainage plates arranged in soft soil, drainage under layers paved on the surface of the soft soil, a bagged sand quilt cofferdam, prefabricated wall panels used for protection and soil blocking, reinforced belts previously buried in the bagged sand quilt cofferdam, a filling material between the wall panels and the bagged sand quilt cofferdam, pile foundations below the panels, copestone above the panels and reverse filtering geotextile behind the bagged sand quilt cofferdam. The structure is implemented step by step, and the deformation of the soft soil foundation and the cofferdam is basically finished before the wall panels are constructed, so that post-construction settlement and uneven settlement are reduced. The bagged sand quilt cofferdam can also be used as the construction platform of the wall panels and the pile foundations, so that intertidal zone construction is changed into land construction, and construction conditions are improved. The structure can adapt to the bearing capacity and deformation of the soft soil foundation, is simple in construction technology, can be constructed by stages, and saves investment.

Description

technical field [0001] The invention relates to a retaining wall structure, which belongs to the fields of water conservancy engineering and civil engineering, in particular to a reinforced earth bank wall structure based on soft soil foundation conditions in tidal flat areas. Background technique [0002] In my country's coastal areas, a large area of ​​usable land can be formed by enclosing and painting land. In order to meet the requirements of flood control and drainage, hydraulic structures such as flood drainage canals and flood detention areas must be built within the newly formed land area. The quay wall structure of these buildings A steeper slope is usually chosen to reduce land occupation. [0003] Conventional structural types include gravity type, cantilever type, buttress type, empty box type, etc. These structures have high requirements on the bearing capacity of the foundation and cannot adapt to large deformations, so there are strict requirements on the bea...
