DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-8 The utility model provides a technical solution: a river channel retaining wall for preventing embankment collapse, comprising a soil layer 1, and also comprising:

[0034] The side wall 2 is made of concrete and is fixed to the inner side of the soil layer 1 in a stepped manner to protect the soil layer 1;

[0035] Drainage units 5 are arranged at intervals between the side wall 2 and the soil layer 1 for draining floodwater during flood season;

[0036] The water tank 7 is arranged inside the soil layer 1 and connected to the drainage unit 5, and is used for caching water.

[0037] It should be noted that during operation, the soil layer 1 is dug into the required shape by an excavator, a mold is installed at the position where the drainage unit 5 needs to be opened, the water tank 7 is placed at the position where it needs to be installed, and then the side wall 2 is cast into the required shape according to the construction requirements. After the side wall 2 solidifies, the installation mold is taken out from the side wall 2, and then the drainage unit 5 is installed in the installation hole reserved in the side wall 2 to complete the installation of the entire retaining wall. During the flood season, the water level of the river rises, and a large amount of groundwater accumulates in the soil layer 1. The groundwater is discharged into the river through the drainage unit 5, and the water level is relatively high. When the water pressure is high, the water in the river channel can be squeezed into the drainage unit 5 and drained to the upper part for discharge. The water tank 7 is used to cache the groundwater that seeps downward in the river channel and receives the groundwater filtered in the upper soil layer 1. When the water level in the river channel is high and the groundwater drainage is not smooth, the groundwater can be drained into the water tank 7. The water tank 7 can cache the water volume and reduce the effect of water pressure. When the water level in the river channel drops, the water is discharged along the drainage channel by gravity. By setting up this device, the groundwater in the river channel can be effectively relieved and discharged, and the pressure of the river channel on the side wall 2 can also be decomposed, thereby effectively maintaining the stability of the installation of the side wall 2.

[0038] In one embodiment, the side wall 2 includes a first wall 21 fixed at a vertically inclined position at the lower part of the soil layer 1, a second wall 22 fixed at a vertically inclined position at the upper part of the soil layer 1, and a pedestal 3 fixed at a horizontal position between the first wall 21 and the second wall 22. The first wall 21, the pedestal 3 and the second wall 22 are arranged in three sections.

[0039] In a specific embodiment, the support platform 3 is detachably fixed between the first wall 21 and the second wall 22 .

[0040] This design, in which the side wall 2 is arranged into three sections, can make the construction convenient and safe, and can reduce the stress on the retaining wall. It is suitable for situations where the river channel is deep and the water pressure is high. The pedestal 3 is laterally detachable, which can buffer the water pressure on the one hand, and facilitate the salvage of fallen objects and the later maintenance of the water tank 7 on the other hand.

[0041] In one embodiment, the drainage unit 5 includes a first drainage pipe 51 transversely penetrated on the first wall 21, a second drainage pipe 54 transversely penetrated on the base 3, and a third drainage pipe 57 transversely penetrated on the second wall 22. The first drainage pipe 51, the second drainage pipe 54 and the third drainage pipe 57 penetrate into the interior of the soil layer 1.

[0042] With this design, the water source accumulated in the soil layer 1 is discharged into the river channel from the first drainage pipe 51 , the second drainage pipe 54 and the third drainage pipe 57 , which can effectively reduce the water source in the soil layer 1 .

[0043] In one embodiment, the first drain pipe 51 and the second drain pipe 54 are connected via a first connecting pipe 52 vertically penetrating the first wall 21;

[0044] The second drain pipe 54 and the third drain pipe 57 are connected to each other through a second connecting pipe 56 vertically penetrating the second wall 22;

[0045] The first connecting pipe 52 and the water tank 7 are connected via a drain pipe 53 arranged transversely;

[0046] The second drain pipe 54 and the water tank 7 are connected via a vertically arranged water inlet pipe 55 .

[0047] This design, see Figure 3 When the water level of the river exceeds the first wall 21 but does not exceed the pedestal 3, the river water flows from the first drainage pipe 51 into the first connecting pipe 52, and then is discharged from the second drainage pipe 54. When there is a lot of river water, the river water will flow into the water tank 7. When the water level is higher than the pedestal 3 or the water in the water tank 7 is full, the overflowing water or river water can be drained to the third drainage pipe 57 through the second connecting pipe 56 inside the second wall 22 on the upper part of the pedestal 3, and finally discharged into the river.

[0048] In one embodiment, valve bodies 59 are provided at positions of the first drainage pipe 51 , the drain pipe 53 , the second drainage pipe 54 and the third drainage pipe 57 close to the soil layer 1 , and the valve bodies 59 are one-way water stop valves.

[0049] With such a design and the valve body 59 , water can only be discharged from the soil layer 1 into the river channel, and water in the river channel will not flow into the soil layer 1 , thereby effectively preventing river water from flowing back into the soil layer 1 .

[0050] In one embodiment, a filter layer 58 is disposed on one side of the first drainage pipe 51 , the second drainage pipe 54 , and the third drainage pipe 57 located in the soil layer 1 .

[0051] With such a design, the filter layer 58 is used to filter the sand and gravel in the soil layer 1, which can effectively prevent the sand and gravel from clogging the drainage pipe.

[0052] In one embodiment, steel bars 6 are disposed between the first wall 21 , the cap 3 , the second wall 22 and the soil layer 1 , and the outer side of the steel bars 6 is wrapped with an anti-seepage geotextile.

[0053] With this design, when pouring the side wall 2, the steel bars 6 are inserted into the concrete layer and the soil layer 1, which can improve the stability of the side wall 2 and the soil layer 1. The steel bars 6 are wrapped with anti-seepage geotextile to isolate the soil and the steel bars 6 to avoid corrosion.

[0054] In one embodiment, a reinforcement unit 4 for reinforcing the second wall 22 and the soil layer 1 is provided at the upper end of the second wall 22;

[0055] The reinforcement unit 4 includes a cover plate 41 fixed to the second wall 22 and the upper end of the soil layer 1 , an anchor rod 42 fixed to the cover plate 41 , and a guardrail 43 fixed to the upper end of the anchor rod 42 , wherein the anchor rod 42 passes downward through the second wall 22 and the soil layer 1 .

[0056] In a specific embodiment, the cover plate 41 is cast by concrete, and the edge connected to the second wall 22 protrudes downward, so that the second wall 22 can be clamped and fixed.

[0057] With this design, the anchor rod 42 passes through the cover plate 41 and is driven downward into the soil layer 1 and the second wall 22. The other end of the anchor rod 42 is sleeved and fixed with a guardrail 43, which can maintain a good landscape effect while maintaining the stability of the soil layer 1.

[0058] In addition, if there are descriptions involving "first", "second", etc. in the embodiments, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying the importance of the relative description or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
