Problems solved by technology

[0003] However, many years of engineering practice by my country's water conservancy personnel have proved that the above-mentioned retaining dam structures have certain shortcomings. Gravity retaining dams have made some progress, but there are still some inherent and inevitable shortcomings, such as high cost of flap gates, easy shaft jamming during operation, and disadvantages for management and operation control, and rubber dams are inflated (water-filled) ) long time, complex operation and management of equipment and pumps, inconvenient maintenance and other problems

Embodiment 1

[0025] like Figure 1 to Figure 3 As shown, the present invention is a pocket-type flexible retaining dam, which includes a base plate 1, a buttress 2, a dam pocket 3, a bottom anchor 4, a lateral water-stop structure 5, and a lifting device 7.

[0026] Two supporting piers 2 are arranged on the bottom plate 1, and the bottom plate 1 and the supporting piers 2 are reinforced concrete structures, and the structural dimensions can be calculated and determined according to the actual requirements of the project and the stress conditions. The pier 2 is provided with a columnar hole 21 with an “Ω”-shaped cross-section facing the dam body, a trash rack slot 22 and an equipment slot 23 .

[0027] The dam pocket 3 is a flexible cloth pocket shape, which has the effects of anti-seepage and water retention and high tensile strength. The dam pocket 3 is composed of a pocket cloth surface 31, two pocket side edges 32, a pocket top edge 33 and a pocket bottom edge 34. The pocket cloth surf...

Embodiment 2

[0031] The difference from Example 1 is that when the span of the single hole is large, in order to control the thickness of the dam pocket 3, the dam pocket 3 is designed to be reinforced, and the top edge 33 of the dam pocket 3 is a sleeve structure, and the top edge 33 It is sleeved on the reinforced cable 6, and the two ends of the reinforced cable 6 are respectively connected with the lifting hanging points 71 on the corresponding sides. The reinforced cable adopts a prestressed steel strand with a diameter of 7mm, and the reinforced cable 6 can enhance the overall tensile strength of the dam pocket 3, thereby reducing the thickness of the dam pocket 3, so that the two pocket sides 32 and the lateral stop The water structure 5 is better connected to ensure the water-stop effect.

[0032] The pocket-type flexible retaining dam of the present invention can be arranged continuously in a single span or in multiple spans.

[0033] The bag-type flexible retaining dam of the pr...

Abstract

The invention provides a bag type flexible water retaining dam. The bag type flexible water retaining dam mainly comprises a bottom plate, buttresses and a dam bag. The buttresses are arranged on the bottom plate, the dam bag is in a flexible cloth bag shape, a body of the dam bag is a bag cloth face, and the four sides of the bag cloth face include the bag top side, the bag bottom side and the two bag side faces respectively. The bag bottom side is anchored to the upper surface of the bottom plate through a bottom anchoring part, and the two bag side faces are connected with side water stop structures in the buttresses on the two sides of the dam bag respectively. The bag type flexible water retaining dam has the advantages of being simple and practical in structure, low in manufacturing cost, short in construction period, convenient to manage and maintain and the like, the water stop effect is good, the span is large, the height of the dam can be reduced in the flood reason for draining flood, and water is not stopped; the bag type flexible water retaining dam can be used for urban garden beautifying, and has wide application prospects in seaside city construction.

Description

technical field [0001] The invention relates to a retaining dam structure, in particular to a pocket-type flexible retaining dam, which has simple and practical structure, low cost, short construction period, convenient management and maintenance, and can be widely used in sponge cities such as agricultural irrigation, urban flood control, urban river landscape, etc. under construction. Background technique [0002] At present, with the proposal of the national "sponge city" construction theory, and the rapid advancement of urban flood control construction, ecological river construction and waterfront landscape construction, there are more and more types of retaining dams, usually with gravity retaining dams and sluice structures , flap gates, rubber dams and horizontal water retaining structures, etc. Among them, flap gates and rubber dams are relatively novel, and are widely used in the construction of retaining dams in ecological rivers. Flap gates are my country's hydraul...
