Description

Gravity type dock anti-seepage water-stop structure
Technical Field
The utility model belongs to the technical field of the prevention of seepage, specific gravity type dock prevention of seepage stagnant water structure.
Background
A gravity dock is a dock building which is generally composed of a dock floor, a dock door and a dock wall. The dock gate is arranged at one end of the dock close to water, and the dock is opened or closed through opening and closing of the dock gate. And the dock walls are positioned at two sides of the dock gate.
After water is poured, the water can be filled in and out, after water is drained, the water can be used as a ship repairing and building space, and a ship can be repaired and built on the bottom plate. Namely, when the dock gate is closed, water in the space of the ship built in the dock is discharged, and the working condition of the ship built is met. A decompression drainage system is arranged below a dock bottom plate, and the basic principle of decompression drainage is as follows: in the construction period and the dock service period, water seeping through the water intercepting system is discharged through the stone breaking drainage ditch and the water permeable pipe, and the water converges to the open drainage ditches on the two sides of the dock chamber, so that the dock bottom plate is prevented from bearing excessive floating force. Drainage systems are therefore an important means of ensuring dock safety. However, in the case of a large amount of water, water cannot be discharged in time simply by providing a pressure reduction drainage system on the bottom plate, and the dock bottom plate still bears a large buoyancy. To overcome this problem, it is common practice to provide a ring of water-stop curtains (also known as cut-out walls) down the bottom of the dock. The impervious wall comprises a rear section and a front section, wherein the rear section is arranged below the dock gate of the dock, and the front section is positioned below the dock gate. The water quantity flowing to the dock can be effectively reduced through the impervious wall, the dock bottom plate can not bear overlarge buoyancy force through the matching of the impervious wall and the decompression drainage system, and meanwhile, the dry working face condition in the dock is effectively kept.
The construction steps of the impervious wall are that a waterproof curtain (namely the impervious wall) is constructed firstly, and then upper structures such as a dock bottom plate and a dock wall are constructed, wherein the impervious wall is usually positioned below the dock bottom plate. If the upper structure of the impervious wall and the dock wall bottom plate cannot be effectively sealed and a gap exists, water still permeates into the dock through the gap, and once the gap is large, more permeated water can cause failure of the impervious system. In contrast, a water stopping structure is required to be arranged between the upper structure of the impervious wall and the bottom plate of the dock wall, so that the inward seepage stroke of seepage water is prolonged, and the effectiveness of an impervious system is ensured.
