A retaining wall and construction method applied to the reinforcement of flood control dikes in flood control projects

Abstract

The invention discloses a retaining wall applied to reinforcement of a flood protection engineering floodwall and a construction method, and solves the problem of weakening of the strength of a floodwall caused by formation of recesses due to scouring of a foundation by easy permeation of water into the foundation from joints due to closing of the joints between stones by concrete, wherein commonfloodwalls are built by the stones, and the floodwall is reinforced through building of the retaining wall in the prior art. A frame structure consisting of multiple longitudinal frames and transverseframes is used as the foundation; a first baffle plate, a second baffle plate and a clamping plate are provided; interval space for casting the concrete is respectively formed among the first baffleplate, the second baffle plate and the clamping plate; the clamping plate comprises a concrete plate basal body, and waterproof cloth for wrapping the concrete plate basal body; and the reinforced floodwall built through the retaining wall has the advantages of improvement of the tightness of the retaining wall, difficult scouring of the foundation by water entering the back surface of the retaining wall and improvement of the strength of the floodwall.

Description

technical field [0001] The invention relates to the technical field of water conservancy and flood control, more specifically, it relates to a retaining wall and a construction method for reinforcing flood control embankments in flood control projects. Background technique [0002] About 90% of large and medium-sized cities in my country are on the verge of rivers, lakes and seas, and are threatened by floods to a certain extent. Among them, the ground of more than 100 large and medium-sized cities is below the water level or tide level of rivers. Due to the large population and concentration of wealth in the city, and the city is also the center of local politics, economy, culture, transportation, communication, and information, once a flood occurs, the loss per unit area will be very huge. [0003] Urban flood embankments refer to embankment projects built to prevent rivers from flooding. Levees protect against floods. Urban flood dikes can protect the lives of residents...

AI Technical Summary

Problems solved by technology

However, once the flood embankment breaks or overflows, the flood will submerge the urban area and seriously affect the economic development of the city.

[0004] Chinese invention patent, publication number is CN106930231A, discloses a kind of construction method that is applied to flood control embankment reinforcement of flood control project, and the key points of its technical scheme are: comprise the following steps: (a) construction planning; (b) earthwork filling; ( C) original dike maintenance; (d) foot protection construction; (e) building retaining wall by masonry; (f) turf slope protection; (g) embankment crest road construction; The embankment is reinforced, and the common retaining wall is mostly piled up with stones, and the joint between the stone and the stone is closed with concrete, and the joint between the stone and the stone is the weak point of the retaining wall. Moreover, due to the large number of joints, it is difficult to ensure the sealing of the joints during construction, and water can easily seep into the foundation through the joints, causing erosion of the foundation and forming depressions, which in turn weakens the strength of the flood embankment
