Concrete water penetration component soft mattress

Abstract

The invention belongs to the technical field of channel improvement, and particularly relates to a concrete water penetration component soft mattress. The concrete water penetration component soft mattress comprises a main mattress and a plurality of water penetration components, wherein the main mattress adopts a grid mattress; the water penetration components are positioned at the upper part of the grid mattress; the total area of the water penetration components on the grid mattress is not smaller than the area of the grid mattress. The concrete water penetration component soft mattress has the advantages that the grid mattress adopts a permeable grid structure, the probability of tearing failure caused by concentrated local pressure is low, the reinforced concrete water penetration components connected with the grid mattress can not only play the role of bottom stowage through the dead weight, but also reduce the direct rushing effect on a mattress body by water flow and reduce channel erosion at the edge of the mattress body, the phenomena that the mattress body is torn and the mattress body is suspended and hung are avoided, sedimentation can be formed in the mattress, and the engineering effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of river regulation, and in particular relates to a soft concrete row of permeable components used in river regulation projects for protecting (maintaining) beaches, bottom protection, bank protection, river ecological protection projects and landscape projects. Background technique [0002] Soft drainage is a commonly used engineering technology for river regulation. According to the available statistics, there are nearly ten patents related to soft drainage. There are mainly the following types used in the current project: [0003] Sand rib soft body row (patent number: CN03229837.4). The sand-ribbed soft row mainly includes arrangement and sand-rib ballast. It is characterized in that the geotextile on the arrangement is a single geotextile (or composite geotextile), and the composite geotextile is formed by needle punching of two geotextiles. Evenly distributed reinforcing belts and sand-rib sleeves ar...

Problems solved by technology

[0009] On the whole, the application of the soft platoon is successful, but there are some problems. First, the soft platoon is mainly for defense. It plays a role in stabilizing the arrangement, and it is difficult to improve the distribution of water flow velocity, even because it reduces the roughness of the bed surface, increases the flow velocity near the bottom, and accelerates the destruction of the row body; The problem is more prominent, especially in the area directly impacted by the water flow and the deformation of the riverbed is large. This is because the riverbed around the beach protection belt has a large scouring deformation, and the edge of the row collapses, which is easy to cause tearing and damage at the edge of the row. Under the action of the brush, it continues to develop into the project, resulting in tearing of the arrangement, or even hanging the arrangement in the air.

At the same time, the exposed arrangement is prone to aging damage, and the existing technical improvements are difficult to fundamentally solve the problem of arrangement damage
