Problems solved by technology

[0003] With the increase of service life, the embankment is old and cannot meet the flood control function, and the embankment needs to be demolished and rebuilt
However, due to the tight traffic on the top of the embankment and the dense surrounding buildings, the method of demolishing the embankment and building a new one will interrupt the traffic and have a great impact on the safety of the surrounding building structures, making it difficult to implement the project

Embodiment 1

[0034] refer to figure 1 An old river embankment retaining wall renovation structure shown includes a river embankment retaining wall 1, a wall column 2, a hanging net sprayed concrete layer 3, an anchor rod 4, and an anti-seepage block 5 for embankment foot protection; the embankment retaining wall Wall 1 is longitudinally spaced with pouring troughs, and wall columns 2 are formed by pouring in the pouring troughs. Wall columns 2 and river embankment retaining wall 1 form an integral body, and the outer surfaces of river embankment retaining wall 1 and wall column 2 are flush; the hanging net The shotcrete layer 3 is arranged on the outside of the wall column 2 and the retaining wall 1 of the embankment; the anchor rods 4 are longitudinally arranged at intervals along the retaining wall 1 of the embankment, and one end of the anchor rod 4 is placed in the retaining wall 1 of the embankment, and the anchor rod 4 The other end is connected with the sprayed concrete layer 3; the...

Embodiment 2

[0037] refer to figure 1 In the renovation structure of an old river embankment retaining wall shown, a water-stop structure 6 is provided between the sprayed concrete layer 3 and the embankment foot protection anti-seepage stopper 5; 1. The interval distance between the vertical grooves is 8-12m.

[0038] In actual use, the setting of the water-stop structure 6 plays the role of effectively fastening and sealing, preventing water leakage, water seepage and shock absorption and buffering of the building structure.

[0039] Adopting the technical scheme that the wall column 2 is longitudinally spaced and slotted on the retaining wall 1 of the river embankment at a distance of 8-12 m, the cost is saved on the basis of ensuring the structural safety of the retaining wall of the embankment.

[0040] What water-stop structure 6 adopts is prior art.

Embodiment 3

[0042] refer to figure 1 The old embankment retaining wall renovation structure shown is based on the first embodiment: the surface of the hanging net sprayed concrete layer 3 is provided with a decorative surface layer 12 .

[0043] In actual use, the setting of the decorative surface layer 12 improves the landscape of the embankment on the basis of ensuring the flood control performance, and the overall comprehensive effect and economic performance are better.

Abstract

The invention relates to an old river levee retaining wall renovation structure and method. The structure comprises a river levee retaining wall, wall columns, a net-hanging sprayed concrete layer, anchor rods and levee foot protection seepage-proofing check blocks. Pouring grooves are longitudinally formed in the river levee retaining wall at intervals, the wall columns are formed in the pouring grooves in a pouring mode, the wall columns and the river levee retaining wall form a whole, and the river levee retaining wall is flush with the outer surfaces of the wall columns. The net-hanging sprayed concrete layer is arranged on the outer sides of the wall columns and the river levee retaining wall. The anchor rods are longitudinally arranged at intervals along the river levee retaining wall, the ends of the anchor rods are arranged in the river levee retaining wall, and the other ends are connected with the net-hanging sprayed concrete layer. The levee foot protection seepage-proofing check blocks are arranged at the bottom of the outer side of the river levee retaining wall and are longitudinally arranged along the river levee retaining wall. According to the structure, renovation can be carried out on the basis that an original river levee retaining wall is not dismantled, the river levee can meet the flood control requirement, smooth traffic of a levee top road and safety of surrounding building structures can be guaranteed during construction, the levee top range is widened, the river levee landscape is improved, and social and economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of embankments and embankments, and in particular relates to a repairing structure and method for retaining walls of old embankments. Background technique [0002] Considering the impact of land use on the embankment on both sides of the urban river, retaining walls are often used to reduce the impact. [0003] With the increase of the service life, the embankment is old and cannot meet the flood control function, and the embankment needs to be demolished and rebuilt. However, due to the tense traffic on the top of the embankment and the dense surrounding buildings, the method of demolishing the embankment and building a new one will interrupt the traffic and have a great impact on the safety of the surrounding building structures, making it difficult to implement the project. Contents of the invention [0004] The present invention provides an old embankment retaining wall remediation structure and metho...
