Abstract

The utility model relates to a dam used at the sea gates of rivers and waterway regulation in middle and lower reaches. The whole dam body is composed of a plurality of dam units, which have different length, each dam unit is a hollow structure with both enclosed ends, the cross section is trapezoid-shaped, the cavity of he dam unit is separated into a plurality of chambers with horizontal partition plates, a plurality of water inlets is opened at the bottom of the dam unit, and a plurality of vents are arranged at the top of the dam unit. The utility model requires no sunken fascine mattress during the construction process, is convenient for construction, saves labor, time and expense, is subject to less influence of water depth, velocity and other conditions, and the dam body is firm and easy for removal and movement.

Description

The dam

Technical field

The utility model relates to a kind of dam that is used for rivers marine outfall and middle and lower reaches waterway regulation.

Background technology

At present, in the rivers waterway regulation works, often need by the increase fairway depth of building a dam, its process is general earlier in foundation branch mattress sinking, adopts stone to build a dam in mattress sinking.There is following defective on the dam that this method builds up: one, mattress sinking needs a large amount of felling branches, and vegetation and natural environment are had certain destruction; Two, in the position, river mouth, along with tiding, mattress sinking is often surfaced, rot easily, and stormy waves is big, mattress sinking put fortune, sinking is all had any problem; Three, in the depth of water, flow velocity is big, stormy waves is big river course, stone is thrown into and very easily is shifted in the water and sinks, so whole engineering quantity is big, and the expense height; Four, in the regulation process, the layout of position, dam and determine to be difficult to that pure assurance is arranged is arranged improperly in case find the position, dam, moves very difficultly, and masonry dam is difficult to remove clean, becomes the underwater obstacle in the navigation channel, influences marine operation safety.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of dam of new structure is provided, and makes it need not mattress sinking in the build process, and it is convenient to build, and is subjected to condition influence such as the depth of water, flow velocity little, and dam body is firm, removes conveniently moving.

Dam of the present utility model, its whole dam body is formed by the short a plurality of dam body unit combination of length, each dam body unit is the hollow-core construction of closed at both ends, its shape of cross section is trapezoidal, the inner chamber of dam body unit is divided into several bins by horizontal dividing plate, have several water inlets in the dam body unit bottom, have several exhaust openings at its top.For increasing the intensity of dam body, be connected with pull bar or wallboard longitudinally between the dividing plate of dam body unit or between end face and the dividing plate.Described water inlet and exhaust opening position only are distributed in the top and the bottom of part bin, and at the bin of not arranging water inlet and exhaust opening, its top has the screw of giving vent to anger, and has into water screw on its sidewall, their all available blind nut sealings.

Dam of the present utility model, and construction the time can directly be laid prefabricated dam body unit by lifting appliance and to be put in place, filling sandstone or water in the chamber within it again, it lays, moves, removes all very convenient, simultaneously, is subjected to condition effect such as the depth of water, flow velocity less.

The specific embodiment

As shown in the figure, the dam body on dam of the present utility model is combined by the short a plurality of dam bodys unit 1 of length.As Fig. 2～shown in Figure 4, each dam body unit is the hollow-core construction of closed at both ends, and its shape of cross section is trapezoidal, and the inner chamber of dam body unit is divided into several bins 3 by horizontal dividing plate 2, have several water inlets 4 in the dam body unit bottom, have several exhaust openings 5 at its top.

Be to increase the intensity of dam body, can be as shown in Figure 5 and Figure 6, be connected pull bar 8 or wallboard 9 longitudinally between the dividing plate of dam body unit or between end face and the dividing plate.

The position of described water inlet 4 and exhaust opening 5 only is distributed in the top and the bottom of part bin, at the bin of not arranging water inlet and exhaust opening, its top has the screw 6 of giving vent to anger, and has into water screw 7 on its sidewall, their all available blind nut sealings (as Fig. 2, shown in Figure 3).

The material on dam of the present utility model can adopt steel concrete or metal material etc.

In the work progress of building a dam, at first prefabricated dam body unit 1 is hung onto on the position, dam with lifting appliance, again with dredge pump by the part bin filling silt (also can put part stone) of exhaust opening 5 to its inner chamber, and build loam cake.Having into, the bin of water screw 7 then seals with blind nut effluent water perfusion back.

Be economical with materials and utilize trend, can take stage construction, after promptly first phase is completed, splash, when accretion of bottom reach a certain height, dam body raise on the spot reuse, concrete operation method is: one, be chosen in the dry season, little flood is between the withered time of tide; Two, cut out silt around the dam, alleviate the dam upward pressure; Three, open the loam cake of exhaust opening 5, the mud in the bin is absorbed with dredge pump; Four, open blind nut on the screw 6 of giving vent to anger, the water in the bin is drained; Five, utilize self buoyancy of dam body unit at the incoming tide, the auxiliary lifting of available in case of necessity lifting appliance raises the position, dam, pours water or filling silt to each bin again after adjusting the position again.So just can save raw material and funds greatly.
