[0002] During the laying and leveling construction of the offshore (river) immersed tube foundation, it is necessary to carry out stone throwing and leveling in the excavated foundation trench before the installation of the immersed tube, and then float the prefabricated immersed tube to the upper part of the foundation bed and sink it for installation.

[0003] The riprap base bed is used to replace the original soft soil layer to improve the bearing capacity of the foundation, so that the load from the upper structure is evenly transmitted to the foundation to meet the requirements of deformation and stability, and to make full use of its permeability to reduce the water level difference before and after the building, avoid seepage, and protect the foundation from waves and water flow. The base bed needs to be leveled and locked, and ensure that it is a plane, which is required to be a horizontal plane or an inclined plane.

[0004] In order to solve the above technical problems, a patent document with Chinese patent number 201310009110.X and publication date 2016.02.03 discloses a riprap leveling device, including a riprap pipe, the top and bottom of which are respectively provided with a GPS positioning system and a leveling head, the leveling head is used to scrape the base bed, and the GPS positioning system is used to confirm the plane position and bottom elevation of the riprap pipe.

The leveling head is provided with a sonar system, which is used to detect the seabed trough bed and the base bed elevation.

[0005] However, according to the technical solution disclosed in the patent document, when the immersed tube is installed on the base bed, there is no disclosed technical means for adjusting the angle of the immersed tube, the installation accuracy of the immersed tube is not high, and when the buried tube is compacted with crushed stone, the crushed stone needs to completely cover the immersed tube, which requires a large amount of crushed stone, is not efficient, and has a poor compaction effect.

In the above arrangement, the pipe body connecting device fixes the pipe body through a lifting belt. When the pipe body is driven by the pipe body adjusting device, if the pipe body collides with the terrain structure or gravel in the base trench, the flexibly fixed pipe body is lifted by the lifting belt, and the traditional rigid fixation is replaced by a flexible fixation, which can effectively reduce the possibility of damage to the pipe body during collision and facilitate the lifting or release of the pipe body.

[0049] The lower end of the fixed block 1322 is provided with an elastic buffer 13223, and the elastic buffer 13223 is arc-shaped and matches the tube body on the side close to the tube body.

With the above arrangement, the stone in the material discharge bin is discharged from the pipe mouth of the material discharge pipe, and the high-pressure water gun arranged on one side of the pipe mouth of the material discharge pipe pushes the stone toward the pipe body, so that the stone is accurately laid on both sides of the pipe body, the amount of locked stone is reduced, and the locking effect is good.

[0053] The bottom of the frame 11 is provided with an extension portion 110a extending downward, and both ends of the frame 11 are respectively provided with movable supporting feet 15, and the movable supporting feet 15 include more than two sections of telescopic feet, and adjacent telescopic feet are movably connected, and a telescopic hydraulic cylinder is provided between adjacent telescopic feet, and the uppermost telescopic foot is fixed on the frame.

A swing adjustment hydraulic cylinder 16 is hinged on the discharge bin 12, and the piston rod of the swing adjustment hydraulic cylinder 16 is hinged on the discharge pipe. In this way, when the equipment body fixes the pipe body to the pipe body connecting device, the swing adjustment hydraulic cylinder can be used to drive the discharge pipe to rotate and open by pulling out the pin shaft, so as to facilitate the fixing of the pipe body and avoid interference.

[0054] Because the telescopic hydraulic cylinder is provided, when the second material is unloaded, the equipment body is supported on the gravel of the first material unloading through the movable supporting feet, and the height of the movable supporting feet is adjusted by the telescopic hydraulic cylinder, so that the position of the equipment body can be adjusted more accurately.

[0055] The device body 1 is provided with a GPS positioning system. In this way, the plane position of the device body can be confirmed by the GPS positioning system, which can improve the accuracy of the device body when the pipe body is installed.

[0056] Measuring frames 16 are also provided at both ends of the frame 11, so that the underwater depth of the equipment body can be intuitively known.

[0057] The working principle of the submarine pipeline laying equipment is as follows: first, the lower end of the feed pipe 141 is swung outward by adjusting the hydraulic cylinder 16, and the pipe body is tied to the fixed block 132 through the lifting belt 13221; then, the submarine pipeline laying equipment with the pipe body 2 is lifted by the crane installed on the ship to the position where the base trench is pre-opened on the seabed, and the height of the movable supporting foot is adjusted by the telescopic hydraulic cylinder 151; the feed pipe 100 connected to the hull is used to feed the lower bin 12, and the stones falling into the lower bin 12 are divided into two paths under the action of the material dividing part 124a, respectively entering the feed pipe 141 and falling into the base trench to realize stone laying. During the laying process, the feed sliding device 121 is driven by the driving mechanism, so that the feed sliding device 121 drives the feed bin and the feed pipe along the length direction of the frame. The pipe body is moved in the longitudinal direction to realize continuous laying, and the material feeding is stopped after the laying is completed; then the position of the pipe body is adjusted, and the specific adjustment method is as follows: if the front and rear direction of the pipe body needs to be adjusted, the front and rear adjustment hydraulic cylinder 1313 is started, and the pipe body adjustment device 131 and the pipe body fixing device 132 are driven to move forward and backward by the front and rear adjustment hydraulic cylinder 1313 to achieve the purpose of adjusting the front and rear position of the pipe body; if the height of the pipe body needs to be adjusted, the movable supporting foot is adjusted by the telescopic hydraulic cylinder 151 to achieve the adjustment; if the swing angle of the pipe body needs to be adjusted, the adjustment hydraulic cylinder 1311 is started, and the sliding part 1312 will slide on the crossbeam. Since there is a gap between the rotating shaft 13144 and the through hole, the sliding of the sliding part 1312 will not be interfered with, and the rotating shaft will rotate at the same time to achieve fine adjustment of the angle.

[0058] When the position of the pipe body 2 is adjusted, the lifting belt 13222 is loosened, and the pipe body enters the base trench 3 paved with stones.

[0059] Then, the feeding pipe 100 connected to the hull is used to feed the lower silo 12. The stones falling into the lower silo 12 are divided into two paths by the dividing part 124a and enter the lower silo 141 respectively and fall into the two sides of the tube body. The stones are impacted by a high-pressure water gun so that the stones are firmly locked into the two sides of the tube body. During the locking process, the lowering slide 121 is driven by the driving mechanism to drive the lower silo and the lower silo to move along the length direction of the frame to achieve continuous locking. After locking, the feeding is stopped.

[0060] After the above process is completed, the submarine pipeline laying equipment is hoisted away by a crane, and the above process is used to lay other pipe bodies.
