Description
TECHNICAL FIELD
[0001] The utility model belongs to the water and soil conservation engineering technical field, concretely relates to an ecological bag net cage check dam. BACKGROUND
[0002] The check dam is a soil and stone building constructed in an erosion-prone channel to fix the channel bed. The main function of the check dam is to raise the erosion datum, prevent the channel bottom from being undercut, raise the channel bed, slow down the channel longitudinal slope, reduce the mountain flood flow rate, reduce the mountain flood or debris flow hazards, and store sediment to gradually terrace the channel bottom and create conditions for plant measures and natural vegetation restoration. The existing check dam is usually constructed by gabion stone cages or ecological bags. However, the gabion stone cage has a high construction cost, and the stone needs to be transported from other places. The check dam constructed by the ecological bag has poor stability, and the ecological bag is prone to displacement and collapse. Therefore, there is an urgent need to design an ecological bag net cage check dam that has good stability and low cost. SUMMARY
[0003] In view of the problems in the prior art, the utility model discloses an ecological bag net cage check dam and specifically discloses the following technical scheme.
[0004] An ecological bag net cage check dam is constructed by a plurality of ecological bag net cage units. The ecological bag net cage unit comprises a gabion net cage. An ecological bag filling body is arranged in the gabion net cage. The ecological bag filling body is composed of a plurality of ecological bags. A cavity is arranged at the center of the ecological bag filling body. The cavity is filled with soil.
[0005] Further, the soil is covered with a soil retaining and water filtering layer.
[0006] Further, the soil retaining and water filtering layer is made of non-woven fabric.
[0007] Further, the top surface, the bottom surface and the four side surfaces of the ecological bag filling body each comprise at least one layer of ecological bag.
[0008] Further, the gabion net cages of two adjacent ecological bag net cage units are fixed by iron wires.
[0009] Compared with the prior art, the utility model has the advantages that:
[0010] In the utility model, the ecological bag is used as the filling material in the gabion net cage, which not only has strong stability but also reduces the construction cost of the check dam.
[0011] In the utility model, the cavity at the center of the ecological bag filling body is filled with soil, which reduces the use of ecological bags and further reduces the construction cost of the check dam. BRIEF DESCRIPTION OF DRAWINGS

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0016] REFERENCE Figs. 1-2 The ecological bag net cage check dam is built by a plurality of ecological bag net cage units 8, and the ecological bag net cage unit 8 comprises a gabion net cage 81, the inside of the gabion net cage 81 is provided with an ecological bag filling body, the ecological bag filling body is composed of a plurality of ecological bags 82, the center of the ecological bag filling body is provided with a cavity, and the cavity is filled with a soil body 84. The ecological bag 82 is used to fill the gabion net cage 81, which can not only reduce the cost, but also solve the problem of insufficient stability of the check dam built by the ecological bag alone, and the cavity is left in the center of the ecological bag filling body in the utility model, the cavity can be directly filled with the soil body 84, thereby reducing the use of a part of the ecological bags, and further reducing the construction cost of the check dam.
[0017] In the embodiment, the ecological bag 82 can be filled with a mixture of treated soil and nutrient substances, or the soil of the check dam construction site can be directly filled.
[0018] In the embodiment, the soil body 84 is covered with a soil retaining and water filtering layer 83, the soil retaining and water filtering layer 83 is made of non-woven fabric, and the soil body 84 can be covered by the non-woven fabric, so as to avoid the loss of the soil body 84 from the gap between the ecological bags 82.
[0019] In the embodiment, the top surface, the bottom surface and the four side surfaces of the ecological bag filling body each comprise at least one layer of ecological bag 82, thereby forming a frame for supporting the internal soil body 84.
[0020] In the embodiment, the gabion net cages 81 of two adjacent ecological bag net cage units 8 are fixed by iron wire binding to avoid relative movement between the gabion net cages 81.
[0021] In the embodiment, the ecological bag net cage check dam comprises a base layer 1 laid on the bottom of the erosion ditch, and a retaining wall structure 2 is arranged on each side of the top of the base layer 1. The side of the retaining wall structure 2 close to the side wall of the erosion ditch is arranged flush, and the side of the retaining wall structure 2 away from the side wall of the erosion ditch is arranged in a stepped manner. The base layer 1 is composed of ecological bag net cage units 8 laid flat, and the retaining wall structure 2 is composed of ecological bag net cage units 8 stacked.
[0022] In the embodiment, the upper front end of the base layer 1 is provided with a check dam body 6, and the upper rear end of the base layer 1 is provided with a stilling wall 5. The check dam body 6 is composed of three layers of ecological bag net cage units 8 stacked, and the two ends thereof are connected with the retaining wall structures 2 on both sides. The stilling wall 5 is composed of one layer of ecological bag net cage units 8 stacked, and the two ends thereof are connected with the retaining wall structures 2 on both sides.
[0023] In the embodiment, the top of the check dam body 6 is provided with an overflow port 7.

The filter layer 3 can prevent water and soil loss and erosion, and can ensure normal water permeability.
[0025] In the embodiment, the filter layer 3 is made of non-woven fabric.
[0026] In the embodiment, the filter layer at the bottom of the erosion ditch and the filter layers on both sides are made of a continuous non-woven fabric to ensure that there is no joint of the non-woven fabric in the width direction of the erosion ditch, so as to facilitate the laying of the non-woven fabric and improve the effect of preventing water and soil loss. In other embodiments, the filter layer 3 can also be in the form of multiple non-woven fabrics overlapped, but the length of the overlap at the overlap is not less than 30 cm.
[0027] In the embodiment, a sand cushion layer 4 is laid between the base layer 1 and the filter layer 3 at the bottom of the erosion ditch. The sand cushion layer 4 can prevent the settlement of the base layer 1.
[0028] The manufacturing method of the ecological bag net cage unit in the utility model is as follows:
[0029] First, the filled ecological bag 82 is stacked along the bottom and side of the gabion cage 81 to form a concave structure with an open top, the height of the side stack is at least one layer of ecological bag 82 from the top of the gabion cage 81, then a whole non-woven fabric is laid into the formed concave structure, so that the non-woven fabric is in close contact with the bottom and side of the concave structure, and the top of the non-woven fabric is left with enough excess to close and cover the top surface of the soil 84, then the soil 84 is filled into the non-woven fabric until the soil is filled to the level of the side ecological bag 82, then the top of the non-woven fabric is used to cover and close the soil 84, and at least one whole layer of ecological bag 82 is continued to be stacked on the upper part after the closing is completed until the gabion cage 81 is completely filled, and finally the upper end cover of the gabion cage 81 is closed and locked, thereby completing the production of the whole ecological bag gabion unit 8.
