Unilateral cantilever type water survey platform system

Abstract

The invention discloses a unilateral cantilever type water survey platform system, comprising a working boat, a unilateral cantilever survey platform, a boring tower and equipment. The working boat isprovided with a plurality of windlasses, at least two shaped steels are arranged on the deck of the working boat, a plurality of supports are arranged on the shaped steels in a crossing way and extends out one side of the boat body, floor board and channel steel are laid on the supports, wherein the position of channel steel corresponds to the position of the shaped steel, the channel steel is infixed connection with the support and the shaped steel, and the parts of the support and the floor board, extending out the boat body, are the working area cantilever sides. The boring tower is arranged on the unilateral cantilever survey platform. The equipment, comprising the boring tower inside the working area cantilever side and the slurry pumps on the boat body, is arranged on the survey platform. The invention is simple, has low cost, and can be used for geotechnical coring, sampling and in situ testing when exploring underwater, thereby ensuring exploration goes smoothly under any environments and conditions.

Description

technical field [0001] The invention relates to an auxiliary system for water engineering geological exploration, in particular to a single-side cantilever type water exploration platform system. Background technique [0002] At present, the platform system required for marine engineering geological exploration has the following defects: 1) Due to the influence of natural conditions such as the terrain, landform, wind, wave, and tidal current in the operating area, the requirements for the stability of the ship are relatively high, and the general exploration platform cannot meet the requirements. Operating conditions; 2) The above-water exploration hole has a certain depth, and the effective operation time is relatively short. The type of drilling rig, the lifting and lowering speed of the drill pipe, and the mud circulation have formed a set of technological processes. It is difficult for a single drilling rig to meet the needs of deep-hole exploration and drilling on the w...

[0002] At present, the platform system required for marine engineering geological exploration has the following defects: 1) Due to the influence of natural conditions such as the terrain, landform, wind, wave, and tidal current in the operating area, the requirements for the stability of the ship are relatively high, and the general exploration platform cannot meet the requirements. Operating conditions; 2) The above-water exploration hole has a certain depth, and the effective operation time is relatively short. The type of drilling rig, the lifting and lowering speed of the drill pipe, and the mud circulation have formed a set of technological processes. It is difficult for a single drilling rig to meet the needs of deep-hole exploration and drilling on the water. ; 3) The effective height of the drilling rig directly affects the drilling speed and quality. If it is too high, the ship will have poor stability and is easy to sway; The speed of drilling; 4) During water exploration, the mud is diluted quickly, which is difficult to recycle and easily cause water environmental pollution; 5) If a platform system similar to that used in offshore oil exploitation is used, the investment in equipment and personnel is very large, and the survey cost Expensive, unacceptable for general engineering survey work
