Problems solved by technology

The anchorage of the wedge mainly depends on the extrusion of the front wedge and the anchor groove to the dam bag and the bottom gasket as the fixing method of the dam bag. After a long time of use, the rubber dam is prone to extrusion deformation and gaps between the wedge and the anchor groove And other problems, which lead to problems in the fixing firmness of the dam bag. In addition, since different positions of the rubber dam are impacted by the water flow differently, the force of the dam bag in the anchor groove of the corresponding position on the anchor shaft along its direction is also different. Different, the anchor shaft is also prone to deformation and damage after long-term use

Embodiment example 1

[0036] refer to Figure 1-Figure 4 , as a new type of dam, the rubber dam has the following outstanding advantages compared with other types of gates and dams: ① Save three materials. Generally, 30% to 50% of steel can be saved, 20% to 50% of cement can be saved, and 60% of wood can be saved. ②The cost is low. Compared with the cost of steel structure gates of the same scale, the investment can generally be reduced by 30% to 70%. ③No water blocking and good water stopping effect. The main disadvantages of rubber dams are poor firmness and easy aging. This is because the main material of the dam bag is adhesive tape with a thickness of several millimeters. Although it is relatively flexible, it is not robust enough to be easily damaged by machinery. It needs to be carefully maintained during use to prevent it from being stabbed by sharp objects. Using the rubber dam project to increase the amount of groundwater resources in the riverside area is an important way to solve th...

Embodiment example 2

[0047] Before the construction of the rubber dam, the following preparations are required:

[0048] It should include two aspects: one is civil engineering; the other is the customization of rubber dam bags. Civil engineering involves the construction of cofferdams, construction diversion, excavation of foundation pits, foundation floor construction, anchor trench construction, and laying of related control and observation pipelines. The civil construction process flow is: clearing the river bed→site layout→damming and intercepting (or repairing cofferdam)→setting construction drainage→excavating the foundation pit→pouring the foundation floor, bank wall, stilling basin (apron)→the later stage of the anchoring groove Concrete → masonry bedding, seamanship, slope protection → burying bolts and pipes, etc. For dam bags, the dam bags need to be inspected to ensure the quality of the dam bags. After leaving the factory, it is necessary to strictly check whether their quality and s...

Abstract

The invention discloses a rubber dam for a water storage reservoir. The rubber dam comprises a foundation slab arranged at the bottom of a riverbed, two boot-shaped anchoring grooves, a dam bag and abottom gasket, wherein the two anchoring grooves are correspondingly reserved at the upstream and the downstream of the foundation slab, an anchoring shaft for rolling the bottom gasket and the dam bag is arranged in a protruding groove in the front portion of the anchoring groove, the anchoring groove is provided with a front wedge block and a rear wedge block which extrude the dam bag and the bottom gasket, a plurality of positioning shells are arranged on the portions, rolling the dam bag and the bottom gasket, of the anchoring shaft in the axial direction of the anchoring shaft in a sleeving mode, and the positioning shells are provided with openings where the dam bag and the bottom gasket pass. A construction method of the rubber dam is further disclosed. The rubber dam and the construction method have the beneficial effects that compared with traditional wedge block anchoring, an independent dam bag fixing structure is additionally arranged, the fixing firmness is not prone to being influenced by loss caused by long-time use, the overall structural firmness of the rubber dam is enhanced, and the phenomena of water leakage, damage and the like are avoided.

Description

technical field [0001] The invention relates to a rubber dam used for a water storage reservoir and a construction method thereof, which are mainly applied in the technical field of construction engineering in water. Background technique [0002] With the rapid development of science and technology, a new type of building, the rubber dam, has emerged in the water conservancy construction industry. The dam height of this kind of dam can be adjusted according to actual needs, and the dam crest can function as an overflow weir, which is more flexible in practical application. In 1966, my country's first rubber dam came out. Although my country's rubber dam construction started late, it has developed rapidly. In recent years, a large number of rubber dam projects have been completed, and huge economic and social benefits have been achieved in the fields of agricultural irrigation, urban water supply, ecological culmination, landscape construction, and wetland protection. . The...
