Problems solved by technology

Although the temporary flood control wall plays the role of temporary flood control, it is equally important as the permanent flood control wall. It is a part of the flood control shoreline. Once a problem occurs, it may cause major losses and negative impacts, so it must be taken seriously
[0003] see figure 1 , the temporary flood control wall 10 is generally built on the land behind the permanent flood control wall 20, and is located at the opening of the permanent flood control wall 20, and its structural section mostly adopts a vertical masonry structure, such as figure 2 As shown, the construction cost of this structure is relatively high, and it is used for one-time use. It needs to be dismantled after the construction is completed, and it cannot be reused. It is neither economical nor environmentally friendly.

Embodiment 1

[0037] see image 3 with Figure 4 , shown in the figure is a new type of prefabricated temporary flood control wall that is easy to assemble flexibly, including a row of flood control wall structures 100, and the flood control wall structure 100 is spliced ​​by several prefabricated retaining wall units 110 arranged side by side along the extending direction of the river bank. become.

[0038] see Figure 5 to Figure 8 , the longitudinal section of the prefabricated retaining wall unit 110 is an inverted T shape, which is composed of a retaining wall bottom plate 111 and a retaining wall body 112 arranged on the retaining wall bottom plate 111 . The prefabricated retaining wall unit 110 is a hollow structure and its interior is formed with a water irrigation chamber (not shown in the figure). The connected water filling hole 113 can fill the water filling chamber through the water filling hole 112 . The prefabricated retaining wall unit 110 is integrally injection-molded ...

Embodiment 2

[0042] The structure of the new prefabricated temporary flood control wall that is convenient for flexible assembly in this embodiment is roughly the same as that of the new prefabricated temporary flood control wall that is convenient for flexible assembly in Example 1, the difference is that: see Figure 9 with Figure 10 , the retaining wall bottom plate 112 of each prefabricated retaining wall unit 110 is located on the plate surface of the retaining wall wall body 111 front side and is provided with two anchor rod installation through holes 114 at intervals along the length direction, and the retaining wall of each prefabricated retaining wall unit 110 The bottom plate 112 is located on the rear side of the retaining wall body 111 and is provided with two bolt installation through holes 115 at intervals along the length direction. Of course, the number of anchor rod installation through holes 114, 115 is not limited to the number of this embodiment, which should be design...

Embodiment 3

[0046] The structure of the new prefabricated temporary flood control wall that is convenient for flexible assembly in this embodiment adopts two rows of flood control wall structures 100a arranged at intervals along the direction of facing the water, and the structure of each row of flood control wall structures 100a is basically the same as that in Embodiment 2. The structure of the new prefabricated temporary flood control wall, which is convenient for flexible assembly, is the same.

[0047] see Figure 11 to Figure 13 , in order to further improve the stability of the overall structure, the upper connecting buckle frame bars 133 on the adjacent two rows of flood control wall structures 100a are connected through a horizontal connecting horizontal plate 160, and the horizontal connecting horizontal plate 160 is connected to two upper connecting buckling frames The bar 133 is integrally formed.

[0048] In order to further improve the stability of the overall structure, a ...

Abstract

The invention discloses a novel prefabricated temporary flood prevention wall convenient to flexibly assemble. The novel prefabricated temporary flood prevention wall comprises at least one row of flood prevention wall structures, wherein each row of flood prevention wall structures is formed by splicing a plurality of prefabricated retaining wall units arranged side by side in the extending direction of a river bank, each prefabricated retaining wall unit is of a hollow structure, a water filling cavity is formed in each prefabricated retaining wall unit, and at least one water filling hole communicating with the corresponding water filling cavity is formed in each prefabricated retaining wall unit. The novel prefabricated temporary flood prevention wall has the advantages of being capable of being repeatedly used, easy and fast to construct, capable of saving investment, safe, reliable and the like, and has high generalizability and high practical value.

Description

technical field [0001] The invention relates to the technical field of temporary flood control walls, in particular to a novel prefabricated temporary flood control wall which is convenient for flexible assembly. Background technique [0002] In the process of water conservancy project river improvement, when the permanent flood control wall is reconstructed, a temporary flood control wall must be built for the purpose of flood control. Although the temporary flood control wall plays the role of temporary flood control, it is equally important as the permanent flood control wall. It is a part of the flood control shoreline. Once a problem occurs, it may cause major losses and negative impacts, so it must be taken seriously. [0003] see figure 1 , the temporary flood control wall 10 is generally built on the land behind the permanent flood control wall 20, and is located at the opening of the permanent flood control wall 20, and its structural section mostly adopts a vertic...
