Description

one

The invention relates to floating installations for geotechnical research, and in particular to engineering geological vessels.

A geotechnical survey vessel equipped with a device for underwater drilling and sampling with casing and soil survey equipment is known.

However, these vessels do not have the necessary seaworthiness and do not ensure the reliability of the technological equipment.

The production of engineering and geological studies requires the drilling of a large number of wells, which is very laborious and leads to a great investment of time. Sampling of soils (especially sludge) is associated with great difficulties and their research in laboratories over a considerable period of time leads to incorrect results due to partial or complete loss of initial properties by samples.

The purpose of the invention is to increase the seaworthiness and operational qualities of the vessel, the integrated mechanization of research and hydraulic engineering works.

For this, the proposed vessel is made in the form of a catamaran, whose bridge, together with the hull decks, serves as a platform for

installations of drilling equipment and a complex of equipment and mechanisms for the production of research and hydrotechnical works, and between the hulls of the vessel there is a lifting and lowering device technologically connected with the mechanisms and equipment for research and hydrotechnical works installed on the vessel.

For free movement of the vessel without excavation of casing pipes, the catamaran bridge at the point of passage of the casing pipes can be made with a slot, and for fixing the vessel relative to the ground, winches and rock piles can be located at the ends of the hulls.

In addition, to improve the maneuverability and handling characteristics of the vessel, each hull can be equipped with a propulsion system with a propulsive-steering complex.

In order to improve the conditions of vessel control, as well as the performance of research and hydrotechnical works, it can be performed with a superstructure in the middle part, combined with a lifting ram and containing a wheelhouse for controlling the movement of hydrotechnical and research works.

FIG. 1 shows the proposed vessel in the position “in a hiking, side view and plan view; in fig. 2 - the same, in the working position in the study of soils, side view and plan view.

The vessel is made in the form of a catamaran 1, whose bridge together with the decks of the hulls forms a platform 2.

At one end, drilling equipment, for example, a drilling machine 3, is installed at site 2. Behind superstructure 4, there is an underwater penetration-logging device 5 PSPK-69 with a multiplexing mechanism MOB 6 and a lifting and lowering device 7 technologically connected with mechanisms 6.

Equipment for the study of soil includes a seismic acoustic station "Soil 8.

Each body is equipped with a power plant with a propulsive-steering complex 9.

Superstructure 4 is combined with the control room 10 and the lifting frame 11.

The vessel is installed above the place of investigation in two ways: with shallow water depths (up to 7.0 m) - with the help of two captive piles 12, and at great depths - with the help of four Koreas 13, cables 14 and main winches 15.

The housing has a slot 16 for the possibility of leaving the installation from the work site without removing the casing.

Arriving at the geological survey site, the vessel is secured by one of the methods described. After that, the drilling plant and the logging station begin to work. With the help of penetration-logging station, a study of bottom loose deposits is carried out, which can be penetrated by a complex probe to a depth of 25 m. In the process of pressing and extracting the soil, its parameters and properties are automatically determined and recorded: frontal resistance, lateral failure and normal ground pressure; volume weight and the content of clay fractions.

The underwater part of the penetratiopne-logging station consists of a PSPK-69-1.000.000 installation with a radioactive source {Cesium-137).

The raising and lowering of the PSPK-69 device 5 is carried out with a special winch via a cargo ram 11, and the mounting "traveling" is done with special brackets. The drilling of wells is carried out by a rotary and percussion-cable-type drilling rig 3 with an electric drive, installed on a rigid foundation in the bow of the vessel.

To obtain a continuous lithological section between wells,

The acoustic seismic station, which consists of two units with portable electronic equipment installed in the hull of the vessel. Management of all processes is centralized, from the control room.

Processing and obtaining all the necessary soil survey data is carried out directly on board the vessel.

The multipurpose purpose of the vessel also allows, with the help of its mechanisms and lifting device, to produce, if necessary, experimental hydraulic works: driving piles, lowering and laying arrays on the ground, etc.
