Abstract

The utility model discloses a muscle formula clay gunny bag cofferdam, including setting up in the clay gunny bag filling body of both sides and being located two the earth material filling body between the clay gunny bag filling body, the clay gunny bag filling body is piled by multilayer clay gunny bag and is built and form, and the lateral surface, the top surface and the bottom surface cladding of every layer of clay gunny bag have geogrid. The advantages of mechanical construction earthwork filling are fully utilized while the quantity of the clay sacks is reduced as much as possible, the purposes of reducing investment and accelerating construction progress are achieved, meanwhile, steep filling side slopes can be adopted due to the fact that the clay sacks are used on two sides for filling, and compared with a conventional earth-rock cofferdam, small filling sections can be adopted, and site space and engineering quantity can be greatly saved.

Description

Reinforced clay gunny bag cofferdam

Technical Field

The utility model relates to a clay gunny bag cofferdam, concretely relates to add muscle formula clay gunny bag cofferdam.

Background

The temporary cofferdam or flood bank heightening condition in flood control engineering in a flood season generally exists, the engineering generally adopts temporary filling of clay sacks, the clay sacks are small and easy to damage in mechanical construction, and manual bagging and manual piling are basically adopted during construction.

Because the clay sacks need to be manually bagged and piled, the advantages of mechanical construction are difficult to be exerted, and meanwhile, a large amount of manpower, material resources and financial resources are consumed in flood control and flood fighting projects, so that the effect of quick construction is difficult to achieve and the rescue opportunity is delayed.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a muscle formula clay gunny bag cofferdam adds.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is:

the reinforced clay gunny bag cofferdam comprises clay gunny bag filling bodies arranged on two sides and a soil material filling body positioned between the two clay gunny bag filling bodies, wherein the clay gunny bag filling bodies are formed by stacking multiple layers of clay gunny bags, and the outer side surface, the top surface and the bottom surface of each layer of clay gunny bag are coated with geogrids. The advantages of mechanical construction earthwork filling are fully utilized while the quantity of the clay sacks is reduced as much as possible, the purposes of reducing investment and accelerating construction progress are achieved, meanwhile, steep filling side slopes can be adopted due to the fact that the clay sacks are used on two sides for filling, and compared with a conventional earth-rock cofferdam, small filling sections can be adopted, and site space and engineering quantity can be greatly saved.

The geogrids on the adjacent top surface and the bottom surface are fixedly connected, so that the cofferdam structure is firmer and is not easy to loosen.

The geogrids on the adjacent top surface and bottom surface are tied up and fixedly connected through iron wires.

The geogrids coated on the outer side surface, the top surface and the bottom surface of each layer of the clay jute bag are integrally formed.

The inner side surface of the clay sacks filling body is coated with geogrids.

And the longitudinal/transverse tensile strength of the geogrid is more than or equal to 15 KN/m.

And a sub weir filled by clay sacks is also arranged at the top of the clay sacks.

The utility model has the advantages that: the utility model has the advantages of reasonable design it is ingenious, adopt the clay sack to fill in cofferdam both sides, the centre adopts the soil material, geogrid fills, in minimize clay sack quantity, the advantage of make full use of machinery construction earthwork filling reaches the purpose that reduces the investment and accelerate the construction progress, simultaneously because both sides use the clay sack to fill, can adopt steeper filling side slope, compare with conventional stone cofferdam, can adopt less filling section, can save place space and engineering volume greatly.

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is an enlarged schematic view of the structure of the geogrid.

Detailed Description

In the embodiment, referring to fig. 1 and fig. 2, the reinforced clay sack cofferdam provided in the embodiment includes clay sack filling bodies 1 arranged on both sides and a soil material filling body 2 located between the two clay sack filling bodies 1, wherein the clay sack filling body 1 is formed by stacking multiple layers of clay sacks, and the outer side surface, the top surface and the bottom surface of each layer of clay sack are coated with geogrids 3. The advantages of mechanical construction earthwork filling are fully utilized while the quantity of the clay sacks is reduced as much as possible, the purposes of reducing investment and accelerating construction progress are achieved, meanwhile, steep filling side slopes can be adopted due to the fact that the clay sacks are used on two sides for filling, and compared with a conventional earth-rock cofferdam, small filling sections can be adopted, and site space and engineering quantity can be greatly saved.

The geogrids 3 on the adjacent top surface and bottom surface are fixedly connected, so that the cofferdam structure is firmer and not easy to loosen.

The geogrids 3 on the adjacent top surface and bottom surface are tied up and fixedly connected through iron wires 4.

The geogrids 3 coated on the outer side surface, the top surface and the bottom surface of each layer of the clay jute bag are integrally formed.

The inner side surface of the clay sacks filling body 1 is coated with geogrids 3.

And the longitudinal/transverse tensile strength of the geogrid 3 is more than or equal to 15 KN/m.

The top of the clay sacks filling body 1 is also provided with a sub weir filled by clay sacks.

The utility model has the advantages of reasonable design ingenious, adopt the clay sack to fill in the cofferdam both sides, the centre adopts the soil material, geogrid 3 fills, in the quantity of minimize clay sack, the advantage of make full use of machinery construction earthwork filling reaches the purpose that reduces the investment and accelerate the construction progress, simultaneously because both sides use the clay sack to fill, can adopt steeper filling side slope, compare with conventional earth and rockfill cofferdam, can adopt less filling section, can save place space and engineering volume greatly.

The foregoing is illustrative of the preferred embodiments of the present invention and is not to be construed as limiting the invention in any way. The technical solution of the present invention can be used by anyone skilled in the art to make many possible variations and modifications, or to modify equivalent embodiments, using the technical means and contents disclosed above, without departing from the scope of the technical solution of the present invention. Therefore, the equivalent changes made according to the shape, structure and principle of the present invention should be covered in the protection scope of the present invention.
