Embodiment 1

[0023] Such as figure 1 , 2 As shown, the retaining structure described in the present application includes geogrid 4, geotechnical connecting rods, earthwork filler, waterproof structure 6, grid connecting buckle 7, and drainage body 8 composed of crushed stones.

[0024] When building the above-mentioned retaining structure, the geogrids 4 are laid at equal or unequal intervals in the vertical direction, and the geogrids 4 on the same layer and between layers are connected by connecting rods. The space is filled with earth-rock filling material and rolled, and the slope surface adopts a waterproof structure 6 connected with the geogrid, and the geogrid and the waterproof structure are connected by a grid connection buckle 7. A closed waterproof structure 6 is arranged outside the body.

[0025] The soil has a certain compressive strength, but the shear strength is very low, and the geogrid 1 has a high tensile strength. Embedding the geogrid 1 in the soil not only diffuses...

Abstract

The invention discloses a blocking protection structure, particularly discloses a blocking protection structure used for a near-water soft foundation slope, and belongs to the technical field of design and construction of civil engineering buildings. The blocking protection structure used for the near-water soft foundation slope is high in adaptability to foundation deformation, low in investmentcost and good in blocking protection. The blocking protection structure comprises a consolidation system, a built edge filling system and a water blocking protection system. The outer side of the near-water soft foundation slope is filled with the built edge filling system through the consolidation system, and the outer side of the built edge filling system is covered with the water blocking protection system.

Description

technical field [0001] The invention relates to a retaining structure, in particular to a retaining structure for slopes on soft foundations near water, and belongs to the technical field of civil engineering building design and construction. Background technique [0002] At present, more and more construction projects are being carried out in the alpine and valley areas, and the construction sites are extremely scarce. In order to meet the construction needs of the projects, large-scale site leveling has to be carried out. At present, the traditional retaining wall is mainly used for site leveling protection. The retaining wall is restricted by factors such as height and foundation bearing capacity, so the site area that can be leveled is small, and the project investment is relatively large. [0003] In order to better solve the retaining problem of large-scale construction sites with poor foundation conditions, high slopes and waterfronts, and considering the factors of p...
