Embodiment Construction

[0028] The present invention will be further described below in conjunction with embodiment:

[0029] A dam body, the facing surface of the dam body 1 is laid with a composite concrete waterproof board 2, and the composite concrete waterproof board 2 is provided with inorganic composite ribs 3 to form a separate waterproof protection layer of the dam body, so as to solve the cracks on the foundation surface of the concrete structure of the dam body The problem is that the interior of the dam body 1 and the pile foundation of the foundation of the dam body 1 are provided with inorganic composite reinforcements 3 .

[0030] Further, the inorganic composite bars 3 are hollow tubular basalt fiber composite bars. Compared with high-tech fibers such as carbon fiber, aramid fiber, and ultra-high molecular weight polyethylene fiber (UHMWPE), basalt fiber not only has the characteristics of high strength and high modulus, but also has good high temperature resistance, oxidation resista...

Abstract

The invention provides a dam body and a reverse building method seamless waterproof construction technology thereof. The upstream face of the dam body is paved with composite concrete waterproof plates to form a separated dam body waterproof protective layer, the composite concrete waterproof plates are provided with inorganic composite reinforcements, and inorganic composite reinforcements are correspondingly arranged in the dam body and the pile foundation of the dam body foundation. The inorganic composite reinforcements are basalt fiber composite reinforcement in a hollow tube shape. The reverse building method seamless waterproof construction technology of the dam body comprises the following steps that the inorganic composite reinforcements are combined and mounted; inorganic composite reinforcements are arranged; the dam body is built and constructed; and composite cement grouting is conducted on the dam body after the main body structure of the dam body is completed. According to the dam body and the reverse building method seamless waterproof construction technology thereof, liquid seamless construction is achieved, the problem of seams is avoided, meanwhile, cracks and defects of a concrete structure body can be repaired under the pressure action, and the problem of sealing leakage is solved.

Description

technical field [0001] The invention relates to the technical field of dam body construction, in particular to a dam body and a jointless waterproof construction technology of a reverse construction method thereof. Background technique [0002] In recent decades, the domestic industry and construction industry have developed rapidly. The slag left over from mining every year has caused countless losses of life and property, civil disputes, and serious damage to the ecological environment due to water leakage from tailings ponds. [0003] The main factors related to the water leakage of the dam body are the waterproof quality of the dam body, the treatment of material joints, the stability of the dam body structure, and the water absorption of the dam body. For the corrosive damage of concrete and internal steel bars, the rolling of gravel soil and piping of the dam body, etc., cause leakage. The above problems cause the failure of the waterproof function of the dam body, wh...
