fig. 2 is a schematic view of the structure of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to the drawings, in one embodiment of the present invention, a water vessel drilling platform for engineering investigation is characterized in that the structure includes an iron barge, a crawler-type drilling machine, an outer sleeve, an inner sleeve and an anchorage; the crawler-type drilling machine 5 is arranged above the iron barge 1, a sleeve clamp plate is fixed at a position 10cm below a pipe orifice of the outer live sleeve 6, an inner sleeve 7 is placed on a ship body of the iron barge 1 through the sleeve clamp plate from below a ship orifice 8 during drilling, and the lower part of the sleeve goes deep into the water at the river bottom 9.

In the specific implementation process, in order to match the weight of the drilling ship, the weight of drilling machine equipment and the like selected and ensure that the drilling ship is fixed on the water surface, the weight of the front main anchor 2 is 100-200 kg, the weight of the front anchor 3 and the weight of the rear anchor 4 are 50-100 kg, and the anchor type is a four-claw anchor.

In the specific implementation process, the crawler-type drilling machine 5 is provided with four hydraulic support legs, the hydraulic support legs are put down from the periphery of the drilling machine and fixed, and the safety protective guard 10 with the height of about 1.0m is installed around the ship body.

In the specific implementation process, the five anchor winches are fixed on the hull of the iron barge 1 through bottom bolts, and can be detached after exploration operation is finished.

The width of the iron barge 1 is more than 5.0-6.0m, and the length is 12-15.0m, because the width of the crawler-type drilling machine (5) adopted by the method is about 2.3m, the length is about 3.5m, the length of the front working surface of the drilling machine is about 5.0m during normal tripping operation, the length of the rear working surface of the drilling machine is about 1m, and a drilling platform is refitted by selecting a ship with the width of more than 5.0-6.0m and the length of 12-15.0m, so that enough drilling working surface is ensured, and a certain safety protection distance is provided. The iron barge 1 is too small in size, so that the safety operation condition is not facilitated; the size is too big, the tonnage is heavy, and the cost is also not economical and practical, in addition because the drilling boats and ships of choosing for use are unpowered, and the size is too big, the tonnage is heavy, is unfavorable for migrating on water. The selected iron barge 1 can be towed by a general small traffic ship.

The hole opening on the ship is 150-170mm, because the technology is particularly suitable for drilling within 100 meters of hole depth, the final hole diameter is not less than 91mm in general engineering exploration, particularly on-water geological drilling, so that the diameter of the hole is determined to be larger than 91mm, the diameter of the hole is 130mm according to a drilling technical method, the diameter of a matched geological casing is 127mm, the drilling casing is an inner casing adopted by the method, the inner casing needs to go deep into a hard soil layer at the bottom of a river through an outer live casing according to the method, the size of the inner casing is 5.0-10.0m, and the depth of the inner casing is increased or decreased according to the water depth and the thickness of the loose soil layer at the bottom of the river, so that the inner casing can go deep into the hard soil layer by more than 3 m. The outer sleeve is selected to have a diameter of 146 mm. The size of the outer movable sleeve is 3.0-4.0m, which is mainly determined by the maximum water level expansion condition and the deep depth condition of the inner sleeve under the normal condition, the length is favorable for the inner sleeve to be upwards deep into 1.0m-2.0m, which can ensure that the drilling ship vertically displaces after the water level is expanded but not separate from the inner sleeve and the outer sleeve, and the inner sleeve and the outer sleeve are deep into each other and are favorable for ensuring the stability of the drilling ship body and not generating horizontal displacement, thereby creating favorable conditions for smooth drilling. The drilling hull hole 150mm-170mm can ensure the outer sleeve to be fixed, so that the vertical shaft of the drilling machine, the hull hole, the inner and outer sleeves and the underwater hole are on the same vertical line, and smooth drilling is facilitated.

The outer live sleeve is provided with a 0.3-0.5m short sleeve, because the water level fluctuation is not a fixed value, and the outer live sleeve can be immediately connected to use when needed as a stored power tool.
