Abstract

The utility model relates to a trawl type funnel caisson for retaining flood and building a dam. The trawl type funnel caisson is particularly suitable for flood retaining or flow cutting construction projects in a water conservancy or hydroelectric engineering. The trawl type funnel caisson for retaining flood and building a dam is composed of a caisson barrel, a net rack, a steel cable, etc. The caisson barrel can be in a cylinder shape, a rectangular parallelepiped shape or a cube shape and can be directly formed into the shape of the caisson barrel by the net rack. In addition, the shape of the caisson barrel can be made of cement materials, and the net rack can be prefabricated in the inner wall of the caisson barrel. In addition, a funnel net rack which has a taper hole shape is fixedly arranged at the position of one rear hole which is arranged at one end of the caisson barrel, and the steel cable is fixedly connected with the caisson barrel. The utility model has the advantages of simple structure and design, convenient operation and relatively low cost.

Description

A kind of trawlnet formula funnel caisson

The utility model is a kind of trawlnet formula funnel caisson that water is built a dam that is used to block, and it is specially adapted in the flood retention or river closure construction project in water conservancy or the hydroelectric project.

At present, in the construction of hydroelectric project, all can run into cofferdam and dam project usually, it is the key project in the whole project construction, is the early-stage preparations of dam main body construction and the progress that is determining the duration.Particularly dam project resembles the engineering of damming the Yangtze River in China's Three Gorges Projects, and its scale and difficulty all are without a peer.In the process of damming, the major measure that forms the cofferdam is the cubic metre of earth and stone material that Xiang Jiangzhong jettisonings a large amount of, and with oversize rock material formation bases such as megalith and tetrahedron stones, this method is used till today from Gu, and successful experience was many times arranged, but its weak point is to need to surpass the much more cubic metre of earth and stone material of the design amount of jettisoninging, reason is in the process of jettisoninging, cubic metre of earth and stone material is constantly washed away by river, and it is many that workload has been increased, but also alluvial makes troubles in the cofferdam in order to clear up from now on.For addressing this problem, the engineers and technicians of China and foreign countries are making great efforts always untiringly, but are still continuing to use traditional scheme so far in construction.

The purpose of this utility model designs at the deficiency that exists in the above-mentioned traditional scheme just a kind of trawlnet formula funnel caisson is provided, this constructional device is inspired from the mode of driveboat fishing, utilize the mobile impulse force of current nature, stop with the way of stationary caisson that current are held back simultaneously by current and sweep away the sandstone that come, reach the purpose of the fill of damming.

The purpose of this utility model realizes by following measure and device:

This kind is used to block the trawlnet formula funnel caisson that water builds a dam and is made up of members such as case tube, rack and wireropes, its structural characteristics are, the shape of case tube can be the cylinder bodily form, cuboid or the square bodily form, can directly constitute the shape of case tube with rack, also can constitute the shape of case tube with the material of cement, rack in advance in the inwall of case tube.In addition, at an end one metapore place of case tube, fixedly install the funnel rack of a band taper hole shape, its effect is to collect current to sweep away next sandstone, and wirerope is fixedlyed connected with the case tube, and it can be combined into one and fix its position to a plurality of case tubes.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model space truss structure schematic diagram

Fig. 2 is the structural representation of the external member of the utility model

Fig. 3 is the structural representation of funnel rack

Fig. 4-6 is the structural representation of the utility model different visual angles

Below with reference to drawings and Examples the utility model is further described:

Shown in accompanying drawing 1-6, it is cylindrical shape that this kind is used to block the trawlnet formula funnel caisson that water builds a dam, it is by case tube 1, members such as rack 2 and wirerope 5 are formed, in structure design and processing, the shape of case tube 1 can be the cylinder bodily form, the cuboid or the square bodily form, can directly constitute the shape of case tube with rack 2, also can constitute the shape of case tube 1 with materials such as cement, and it is pre-in the inwall of case tube rack 2, in addition, at an end one metapore 7 places of case tube 1, fixedly install the funnel rack 3 of a band taper hole, the funnel rack 3 of band taper hole can be fixedly installed on the interior place of mouth or the outer place of its mouthful of the one end-metapore 7 of case tube 1.Wirerope 5 is fixedlyed connected with case tube 1, has a plurality of pin-and-holes 4 on the periphery of case tube 1 to connect wirerope 5.

The utility model device in use can adopt the case tube of difformity, different bore, different length according to actual conditions, a plurality of case tube watchman's wooden clappers are bound together, on water channel, form from bottom to up and block the caisson dike in river together, with metapore postpone, utilize flowing naturally of river, Yi Bian sluice downstream, can tackle on one side by water and rush in the interior sandstone of pipe, the sandstone of piling up in the connecting pipe can stop the loss of the earthwork again, reach the purpose of stopping up current.

It is simple, novel, easy to use that the utility model is compared with prior art had a project organization, Relative cost is reduced, and the more widely scope of application is arranged.
