Description

Anti-seepage film covering device for overflow dam

Technical Field

The invention relates to the field of overflow dam protection, in particular to an anti-seepage film covering device for an overflow dam.

Background

Overflow dams, dams whose top can discharge flood, are also called rolling dams. Overflow dams are typically constructed of concrete or masonry. According to the dam type, the overflow gravity dam, the overflow arch dam, the overflow buttress dam and the overflow earth-rock dam are arranged. The latter is limited to low dams with overflow surfaces and dam feet having reliable protective facilities and small single width flow. The dam-in-dam type factory building overflow dam is combined with a factory building, is used as a factory-dam combined flood discharge mode of an in-dam type factory building overflow dam of a flood discharge building, factory building top overflow and factory building top-crossing flow discharge, can be used in high mountain narrow valley areas, is a way for solving the problem that the arrangement positions of an overflow spillway and a power station factory building are not enough when large flow is discharged, and is also a new form developed from the overflow dam. The overflow dam has the overflow form that: 1. dam crest overflow (drop flow); 2. overflowing the dam surface; 3. and overflowing from the dam surface of the large hole. The first two are surface overflow, which can smoothly discharge the floating materials such as ice slush. The weir crest can be provided with or without a gate. The overflow dam without gate has water level flush with the top of dam, and can increase water head to increase discharge amount gradually. The overflow dam with the gate can adjust the reservoir water storage level and the discharge flow. The elevation of the weir crest and the length of the overflow front are determined by reservoir flood regulation calculation according to the functions of the reservoir and the hub building and the water discharge requirement. The weir crest is provided with a gate pier for supporting the gate, and a bridge is arranged on the gate pier for installing gate opening and closing equipment or arranging a channel. The gate of the dam top overflow is easy to overhaul and convenient and reliable to operate, and is the most common overflow dam form.

The design requirements of the overflow dam are as follows: 1. sufficient overflow front length and discharge capacity to meet flood control requirements; 2. the water flow is smooth, and the dam surface has no unfavorable negative pressure or vibration; 3. the downward flow of water does not cause harmful scouring. The drainage flow rate of the high-head overflow dam can reach 30-40 m/s or more, and the wide energy dissipation power of the downstream river bed sheet can reach tens of thousands or even hundreds of thousands of kilowatts. The design from an overflow or water discharge section to a downstream energy dissipater needs to be well solved: cavitation and abrasion, aeration and atomization, vibration of light structures, scouring of riverbeds and bank slopes and the like. The appropriate dam crest and dam face curve form is selected: the water flow has the advantages of large flow discharge capacity, stable water flow form, avoidance of cavitation damage and easy construction.

The anti-seepage film needs to be laid on the overflow dam before the overflow dam is built and used, the water level height on one side of the dam is guaranteed to be high, water is prevented from leaking to the other side from the bottom layer or the middle layer of the dam, the existing anti-seepage film laying operation of the overflow dam is generally finished manually, the film laying efficiency is low, dangerousness exists, and meanwhile, the smoothness of the anti-seepage film laying cannot be guaranteed.
