SU51967A1 - A device for releasing water into a caisson chamber from a chamber located above the ceiling of the caisson - Google Patents

Description

With the introduction of the hydraulic method of caisson work, the need for a suction chamber in the support body located above the caisson ceiling was revealed. Since the caissons descend to a sufficient depth below the water level, and the support body is constructed from materials that allow water to pass through, it inevitably raises the question of removing water from the suction chamber.

In order to facilitate the work of removing water from the suction chamber, a device is proposed by which water is drained from this chamber through a conduit into the chamber of the caisson.

In the schematic drawing of FIG. 1 shows a vertical section of a part of a caisson with a support body laying, a general installation for a hydraulic caisson method and a device for discharging water into a caisson chamber; FIG. 2 is a vertical section of a part of the ceiling of the caisson with indication of the location of the tank, the pipeline with cranes and the rod for closing the cranes; FIG. 3-5 are various shapes of the tank cross-section; FIG. b - section of part of the ceiling of the caisson with a reservoir placed inside the body of the ceiling.

A hermetically sealed tank 2 (Fig. 1 and 2) is attached to the ceiling of the caisson chamber, equipped with three tubes with taps; of these, the tube 3 with a crane 4, passing through the ceiling of the caisson into the sump chamber 5, serves to pass water from the chamber 3 to the tank 2, the tube 6 s. valve 7 serves to drain water from tank 2 into the caisson chamber /, and tube 8 with valve 9 serves to pass air during emptying of tank 2. Valves 4,} l 9 are connected by levers with a common pull 10 passing through the ceiling of the caisson installed in the ceiling of the water pipe, equipped with the gland 11.

Before descending, the water 10 is left free, and under the action of the spring, the taps are in their original position, i.e., tap 4 is open, taps 7 and 9 are closed. Then the water accumulating in the suction chamber is along diversion channels or
