A dike bag strip, a water storage dike and a method for carrying out water surcharge preloading

Abstract

The invention relates to the technical field of civil engineering and construction, and in particular relates to and discloses a border dike water bag strip, a water storing border dike, and a method for performing water bag strip pile-loading and prepressing. The border dike water bag strip comprises a water bag strip body at an outer layer, wherein water is poured in the water bag strip to form a water pouring layer; an air bag strip is also arranged in the water bag strip body; the volume of water in the water pouring layer is in balance with the air pressure in the air bag strip, so as to keep the water bag strip body full and in a great shape. The water storing border dike comprises two transverse isolation dikes and a longitudinal base, wherein the border dike water bag strip is horizontally positioned on the base and is in sealing connection with the isolation dikes to encircle a rectangular structure; at least one waterproof film layer is paved at the bottom part of the rectangular structure and forms a sealed water storing groove with the rectangular structure. A method for performing the water bag strip pile-loading and prepressing ca perform the pile-loading and prepressing for an embankment through the aforementioned water storing border dike. According to the border dike water bag strip, the water storing border dike, and the method for performing water bag strip pile-loading and prepressing, the prepressing water load is sufficient, so that the prepressing effect is good; the settlement and deformation can be easily monitored; the advantages of safety, environmental protection, economy, high operability and recyclability are achieved.

Description

technical field [0001] The invention relates to the technical field of civil and construction engineering, in particular to a dike bladder strip, a water storage dike and a method for carrying out water surcharge preloading. Background technique [0002] The coastal area has a lot of people and little land, the economy is developed, the river network and ponds in the area are dense, and the earth and rock resources are very scarce. In recent years, in order to protect resources and the environment, most quarries have adopted landscape restoration and restricted excavation, and the price of earth and stone required for road construction has risen. However, in coastal areas with very weak foundations, embankment filling and surcharge preloading are quite difficult, including a series of engineering problems, such as embankment filling is easy to induce soil slope slip, rate control of layered surcharge preloading , Unloading of earth and stone at the end of preloading period,...

AI Technical Summary

Problems solved by technology

The embankment proposed by this invention is piled up to the design elevation at one time, which is not allowed and unscientific on embankments with deep soft foundations, so it does not meet the safety control requirements of the construction process, or is only suitable for reclamation of tidal flats or low embankment
