Embodiment 1

[0058] see figure 2 and image 3 , the present embodiment provides an anti-scour structure for embankment protection feet, including a slope protection 30 and a tooth wall 20, wherein the tooth wall 20 is located at the slope toe 100 of the bank slope 10, and is used to prevent the erosion of the water flow on the bank slope 10, and the slope protection 30 is built Built on the bank slope 10 and connected with the tooth wall 20.

[0059] In the toe protection structure provided by this embodiment, the side of the tooth wall 20 facing the slope toe 100 is an inclined surface 201, and the angle formed between the inclined surface 201 and the surface of the bank slope 10 is an obtuse angle, and then the slope protection 30 built on the bank slope 10 The included angle with the tooth wall 20 is an obtuse angle.

[0060] It can be understood that the tooth wall 20 is located below the slope protection 30 and is connected with the slope protection 30 to form an integral structure...

Embodiment 2

[0078] see Figure 4 , the present embodiment provides an anti-scour structure for embankment protection feet, including slope protection 30 and tooth wall 20, wherein tooth wall 20 is located at the slope toe 100 of bank slope 10, and slope protection 30 is built on bank slope 10 and is connected with tooth wall 20 connected. This embodiment is further optimized on the basis of the first embodiment above. Compared with the first embodiment, the main difference is:

[0079] The anti-scour structure of the embankment protection foot provided in this embodiment further includes a horizontal anti-scour net 80 , which is connected to the tooth wall 20 on the side of the tooth wall 20 away from the slope protection 30 . In other words, the horizontal anti-scouring screen 80 is disposed on the side of the right-angled side 202 of the tooth wall 20 and is connected to the right-angled side 202 .

[0080] Further, the upper surface of the horizontal anti-scouring net 80 is flush wit...

Embodiment 3

[0088] See 3 and Figure 5 , the present embodiment provides a construction method for the anti-scour structure of the embankment protection foot, which is used to construct the anti-scour structure of the embankment protection foot provided in the first embodiment, including the following steps:

[0089] S10: Determine the structural parameters of the tooth wall 20 .

[0090] Wherein, determining the structural parameters of the tooth wall 20 includes the hypotenuse slope coefficient m, the depth H and the width b of the wall bottom 200 .

[0091] Further, the slope coefficient m of the toothed wall 20 is determined according to the embankment conditions of the specific construction site, and the depth H of the toothed wall 20 is determined according to the scour depth h of the water flow. m, but it should meet the stability of the tooth wall 20 itself, and adjust it according to the calculation.

[0092] Specifically, in this embodiment, the slope coefficient m of the toot...

Abstract

The invention provides an anti-scour structure of a banket for an embankment and a construction method and relates to the technical field of embankment engineering. The construction method comprises the following steps of determining structural parameters of a key wall; excavating a foundation pit; constructing the key wall; and carrying out back-fill consolidation on construction spaces on two sides of the key wall and the construction foundation pit. In the anti-scour structure of the banket for the embankment constructed by the construction method, the side, facing a slope toe, of the key wall is a bevel, and the included angle formed between the bevel and the surface of a bank slope is an obtuse angle, so that the key wall is in direct contact with the slope toe. Meanwhile, the bevel of the key wall disperses gravity to the slope toe, so that a suspending phenomenon of the key wall as a result of uncompacted backfilled soil texture at the slope toe is avoided and the anti-scour structure of the banket for the embankment is prevented from being damaged, and therefore, the safety and stability of the embankment are further improved effectively.

Description

technical field [0001] The invention relates to the technical field of embankment engineering, in particular to an anti-scour structure and a construction method of an embankment protection foot. Background technique [0002] The foot protection of slope revetment in embankment engineering is extremely important to the stability and safety of the embankment. The foot protection can ensure the stability of the embankment when the river bank is scoured and bottomed out. Most of the damage to the embankment that has occurred is caused by the foundation foot protection Caused by unreasonable structure type. [0003] Such as figure 1 As shown, the foot protection of the existing slope revetment is a rectangular straight wall type. During construction, a 0.5m wide construction space should be reserved on both sides of the straight wall 2. After the construction is completed, both sides of the straight wall 2 will be backfilled with original soil. Compaction, especially the origi...
