Description
Technical Field
The utility model relates to a submarine construction technical field, specifically speaking, the utility model relates to a groundwater discharge system of supplementary earth anchor installation.
Background
Sea pipe landing and hauling is a common process method for laying submarine pipelines. Because the water depth of the near-shore section is shallow, the pipelaying ship can not navigate on the near-shore beach, a far-shore end fixed-point anchoring distribution field with proper water depth is selected, a linear winch device is arranged at the landing point of the marine pipe, one end of a dragging steel wire is connected with a marine pipe dragging head on the pipelaying ship, the other end of the dragging steel wire is clamped in a chuck of the linear winch, the linear winch drags the steel wire rope towards the landing point, the pipelaying ship simultaneously carries out fixed-point pipelaying operation, the dragging steel wire carries the marine pipe to advance towards the landing point, and the pipelaying operation of the near-shore beach is completed in this way.
The ground anchor is a prerequisite for the operation of the linear winch, providing a counteracting counterbalancing force for its towing force of several hundred tons. The earth anchor is installed by carrying out ditching operation before and after a row of driven steel sheet piles, and burying the resistance cross beam and the tying steel wire of the linear winch underground. In general, the design of the resistance beam requires that the depth of the resistance beam embedded underground is greater than the depth of the underground water level, so that underground water can gush out in the ditching process, and normal ditching and subsequent ground anchor installation operation are influenced. Therefore, an efficient underground water drainage system needs to be designed to be synchronous with the ground anchor installation operation.
Disclosure of Invention
The utility model aims to solve the technical problem that a groundwater discharge system of supplementary earth anchor installation is provided, guarantee that the appearance of the lake phenomenon can not appear gushing out to groundwater in the ditching operation process, provide the operating condition for the installation of earth anchor operation.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a groundwater discharge system of supplementary earth anchor installation, includes drainage header, the underground pipe that absorbs water, suction pump, steel sheet pile, line type winch and earth anchor resistance crossbeam, the vertical underground of squeezing into of steel sheet pile, the bottom of steel sheet pile sets up earth anchor resistance crossbeam, and earth anchor resistance crossbeam is connected with the linear winch through the tie wire, underground suction pipe squeezes into the underground in order along the rigid sheet pile surface, and every underground suction pipe all is connected with drainage header through the pipeline, and drainage header is connected with the suction pump, and the suction pump is connected with the drain pipe, by the outside drainage of drain pipe.
Preferably, the underground water suction pipes are provided with a plurality of pipes, and the depth of the underground water suction pipes driven into the ground is slightly deeper than the underground water outlet position.
Adopt the technical scheme of the utility model, can obtain following beneficial effect:
the utility model discloses a groundwater discharge system of supplementary earth anchor installation, according to the effective area of earth anchor ditching operation, retrench the improvement to traditional surrounding type house steward drainage system, adopt the house steward drainage system parallel with the steel sheet pile, all carried out the throttle in the aspect of material, drainage system arrange man-hour, drain pump quantity and flow etc.. On the premise of ensuring the normal operation of the installation of the ground anchor, the construction and material equipment cost is saved.
