Description

Technical Field

[0001] The utility model belongs to the technical field of geotechnical engineering and water transport engineering, and relates to a drilling and soil taking technology on a special soil layer in a special area, in particular to a scaffolding drilling platform suitable for drilling construction on the surface of an open intertidal zone beach. Background Art

[0002] In geotechnical engineering and water transport engineering, such as drilling on the surface of open intertidal flats, it is often required not only to drill holes in the shallow soil layer, but also to drill holes into the deeper soil layer below. In the process of drilling on the surface of open intertidal flats, there are several problems:

[0003] (1) Low efficiency of ship construction: When the hole is deep, it often takes multiple high and low tides to complete. If a drilling ship is used for construction, the ship must be small enough to be positioned at the hole location in the intertidal zone. Secondly, the impact of the tide during high and low tides often damages the drilling casing. At the same time, the repeated positioning of the ship delays the operation time. If the wind and waves are strong, the operation efficiency is even lower.

[0004] (2) The impact of wave action is too great: The waves in the open intertidal zone are generally in the form of rolling waves, that is, the wind-driven waves and ship-shaped waves in the open sea all rush to the seashore in the form of waves, forming large rolling waves. Under such wave conditions, whether it is a small boat, raft or any other floating equipment carrying a drilling rig for construction, it will face the problem of repeated shaking under the action of rolling waves. The casing and drill pipe will move or even break under repeated shaking.

[0005] (3) Soil liquefaction affects safe operations: For projects such as drilling on the surface of open intertidal flats, if the drilling hole is designed to be shallow, close to the shore, and the surface soil is hard, then it is only necessary to lay wooden strips and boards on the surface of the soil without using a drilling vessel and directly put the drilling rig in place for drilling. However, if the drilling hole is designed to be deep, far from the shore, and the surface soil is relatively soft, at this time, if no measures such as ships are used, and a drilling rig such as the XY-100 model is used for drilling, it can be stabilized by placing wooden boards under the drilling rig at first, but after the drilling rig starts operating, the vibration of the drilling rig causes the surface soil of the tidal flat to liquefy, which may cause the drilling rig to sink into the tidal flat, and once the tide rises, the drilling rig needs to be withdrawn to the shore, which seriously affects the progress of the operation.

[0006] In view of the above reasons, it is urgent to develop a drilling platform device that can overcome the influence of rolling waves in open intertidal zones and has high construction efficiency and high safety. Utility Model Content

All pipes can be steel structure pipes or other corrosion-resistant and high-strength metal pipes. The drilling hole 240 is arranged at the center bottom of the semi-cube pipe frame 210; the drilling hole casing 250 is connected to the drilling hole 240; the pipe ladder 220 is connected and fixed to the semi-cube pipe frame 210 with a connecting fastener 260; the upper platform protection rod 270 is connected to the upper side of the outer surface of the semi-cube pipe frame 210 with a connecting fastener 260; the pipe diagonal brace 230 is connected to the semi-cube pipe frame 210 with a connecting fastener 260, and the pipe diagonal brace 230 has an attached pipe diagonal brace 231 fixed on the surface and inside of the semi-cube pipe frame 210, and also has an independent pipe diagonal brace 232 as a supporting diagonal brace to the external ground for fixing the semi-cube pipe frame 210; the sweeping cross bar The distance between 280 and the ground is generally 150 to 200 mm; the bottom area of ​​the semi-cube pipe frame 210 is generally 4000 mm × 6000 mm to 6000 mm × 6000 mm, and the height is generally 3000 mm to 4000 mm; the diameter of the drilling hole casing 250 is generally 128 mm to 146 mm, and the height is generally 3000 mm to 4000 mm; the diameter of the pipe used in the semi-cube pipe frame 210 is generally 48 mm to 60 mm, and the wall thickness is 3.6 mm to 4.0 mm; the upper platform protection rod 270 is a hollow pipe with a diameter of 48 mm to 60 mm and a wall thickness of 3.6 mm to 4.0 mm, which is fixed by a connecting fastener 260.

[0035] The bamboo and wood slat bottom leveling structure 100 comprises a lower leveling plate 110 and an upper structure plate 120. The plane dimensions of the two plates are generally 250mm×2500mm~300mm×3000mm, and the thickness is generally 25mm~40mm.

[0036] First, the lower leveling plate 110 is arranged at a spacing of 1000mm, and the upper structural plate 120 is laid on the lower leveling plate 110 at a spacing of 500mm. The purpose of this is to ensure the integrity of the bottom leveling structure 100 of the bamboo and wood board, so that the gravity transmitted from the upper part can be dispersed to the lower foundation.

[0037] Second, on the surface of the upper structure plate 120, the vertical pipes of the semi-cube pipe frame 210 are erected at a horizontal and vertical spacing of 500mm. The bottom area of ​​the erected semi-cube pipe frame 210 is generally 4000mm×6000mm~6000mm×6000mm, the height is generally 3000mm~4000mm, the diameter of the pipe used is generally 48mm~60mm, the wall thickness is 3.6mm~4.0mm, and it is fixed by connecting fasteners 260.

At the same time, attached pipe diagonal braces 231 are arranged inside and on the surface of the semi-cube pipe frame 210, and its function is also to strengthen the integrity of the semi-cube pipe frame 210.

[0038] Third, after the semi-cube pipe frame 210 is erected, a pipe ladder 220 with a slope of 1:3 is fixed on one side thereof by connecting fasteners 260, and the horizontal and vertical spacings of the pipes of the pipe ladder 220 are both 1000mm; at the same time, above the semi-cube pipe frame 210, in addition to the other three sides of one side of the pipe ladder 220, an upper platform protection rod 270 is arranged.

[0039] Finally, five independent pipe diagonal braces 232 are arranged on the outside of the semi-cube pipe frame 210 and the pipe ladder 220 to prevent the overall frame structure from tilting. A lower leveling plate 110 is provided at the contact point between the independent pipe diagonal braces 232 and the ground.

[0040] In the prior art, regarding projects such as surface drilling in open intertidal zones, firstly, the efficiency of using ships for construction is low. When the hole depth is large, it often takes multiple high and low tides to complete the hole. If a drilling ship is used for construction, firstly, the ship needs to be small enough to be positioned at the hole location in the intertidal zone; secondly, the impact force of the tide during high and low tides often damages the drilling casing. At the same time, the repeated positioning of the ship delays the operation time. If the wind and waves are strong, the operation efficiency is even lower.

[0041] Secondly, the impact of wave action is too great. The waves in the open intertidal zone are generally in the form of rolling waves, that is, the wind-driven waves and ship-shaped waves in the open sea all rush to the seashore in the form of waves, forming large rolling waves. Under such wave conditions, whether it is a small boat, raft or any other floating equipment carrying a drilling rig for construction, it will face the problem of repeated shaking under the action of rolling waves. The casing and drill pipe will move or even break under repeated shaking.

[0042] The third is that soil liquefaction affects safe operations. If the drilling hole is designed to be shallow, close to the shore, and the surface soil is hard, then you only need to lay wooden strips and boards on the surface of the soil, and there is no need to use a drilling ship. The drilling rig can be directly put in place for drilling. However, if the drilling hole is designed to be deep, far away from the shore, and the surface soil is relatively soft, at this time, if you do not use ships and other measures, and directly use a drilling rig such as the XY-100 model for drilling, it will be stable at first if you put a wooden board under the drilling rig. However, after the drilling rig starts working, the vibration of the drilling rig causes the soil on the surface of the mudflat to liquefy, which may cause the drilling rig to sink into the mudflat, and once the tide rises, the drilling rig needs to be withdrawn to the shore, which seriously affects the progress of the operation.

[0043] The working principle of the utility model is that a semi-cube frame drilling platform 200 made of corrosion-resistant high-strength pipe fittings is installed in an open intertidal zone, a drilling hole 240 is opened at the center bottom of the semi-cube pipe fitting frame 210 and a drilling hole casing 250 is inserted, the hole diameter is suitable for the probe of the drilling rig to be lowered, an upper platform protection rod 270 is set around the upper layer of the semi-cube pipe fitting frame 210 (except the climbing direction of the drilling rig) to ensure the safety of the operating personnel, and the pipe fitting diagonal brace 230 is connected to the semi-cube pipe fitting frame 210 around the periphery with a connecting fastener 260. And internal connection, enhance the stability of the semi-cube steel structure drilling platform, connect the pipe ladder 220 with the surface of the semi-cube pipe frame 210 with the connecting fastener 260, and use the drilling rig to drive onto the semi-cube frame drilling platform 200, and lay the bamboo and wood slat bottom leveling structure 100 under the sweeping crossbar 280 of the semi-cube frame drilling platform 200, which is conducive to slowing down the settlement rate of the semi-cube steel frame drilling platform 200 and greatly reducing the possibility of uneven settlement, and can realize drilling construction on the surface of the open intertidal zone. It has the advantages of convenient positioning of the drilling rig, extended daily operating time, good stability and high safety, and is worthy of being vigorously promoted in similar open intertidal zone drilling projects with rolling waves.

[0044] The above description of the embodiments is to facilitate the understanding and use of the present invention by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
