In-situ comprehensive inquiry platform for beach shallow sea engineering geological properties

Abstract

The invention discloses an in-situ comprehensive inquiry platform for beach shallow sea engineering geological properties. The platform comprises a platform ship, a beach shallow sea sounding unit, anin-situ sediment sampling unit, a sea geophysical prospecting unit and a water power in-situ observation unit, wherein the beach shallow sea sounding unit comprises a beach shallow sea static sounding device and a beach shallow sea power sounding device; the platform ship adopts special structural design; on the basis of the platform ship which carries various ocean engineering geological testinginstruments, the quick measurement of the engineering geological properties of an appointed sea area is realized, i.e., the platform ship can stop on the water surface to serve as a fixed platform, and a running navigation test can be carried out to test flow parameters; and in short time, various engineering geology parameters can be measured in the same area in short time, the quick and comprehensive inquiry of engineering geology conditions in a shallow area of which the water depth range is 20m, wherein measurement parameters include water depth, topography and landforms, stratum structures, in-situ sediment soil mechanics parameters and the like. By use of the platform, a test area can be subjected to more reliable engineering geology evaluation, and testing efficiency in different sea areas can be greatly improved.

Description

technical field [0001] The invention belongs to the field of marine engineering geology, and in particular relates to an in-situ comprehensive investigation platform for shallow sea engineering geological properties. Background technique [0002] Shallow seas mainly refer to coastal tidal flats, intertidal zones, and shallow seas with a water depth of less than 20 meters. They have important scientific research, economic and military values. Strategic camps for facility deployment. [0003] In-situ measurement of marine engineering geology is the most direct and reliable system to obtain engineering geological properties. At present, the in-situ measurement technology of marine engineering geology is relatively mature, but due to the special geological conditions and environment of shallow seas are greatly affected by waves and tides, there is an intertidal zone in the shallow sea area, and when the tide is low, it is tidal flats, and other means such as ships cannot be use...

Problems solved by technology

At present, the in-situ measurement technology of marine engineering geology is relatively mature, but due to the special geological conditions and environment of shallow seas are greatly affected by waves and tides, there is an intertidal zone in the shallow sea area, and when the tide is low, it is tidal flats, and other means such as ships cannot be used For engineering geological surveys, when the tide is high, it is relatively shallow, and larger ships cannot enter this area for investigation. There are few in-situ comprehensive measurement systems for engineering geological properties in shallow seas

[0004] Most of the existing shallow sea area test and exploration platforms are pile-type design, which can carry out fixed-point exploration surveys such as static penetration testing. For example, the invention patent application publication number [CN107653860A] discloses a shallow sea area test and exploration platform. Although the structural design has good stability, it still faces the problems of difficulty in disassembly and assembly of traditional measurement platform equipment, difficulty in overall transportation and replacement of exploration sites, and at the same time, it is difficult to carry a variety of equipment due to the size of the platform, and only fixed-point surveys can be carried out; in addition, The invention patent with the application publication number [CN103469775A] discloses a movable lifting multifunctional work platform on water, which can adapt to the construction under severe wind and wave conditions on the water, and can be easily moved to the construction position according to the needs of marine engineering construction, and It is not affected by wind and waves, but it can also only conduct static penetration surveys, and cannot make comprehensive evaluations and obtain comprehensive data for this area
