Abstract
Description
Technical Field
[0001] The utility model relates to the field of static cone penetration, and particularly relates to an improved device for a waterborne static cone penetration rod system. Background Art
[0002] Static cone penetration refers to using a pressure device to press a penetration rod with a cone probe into the test soil layer, and determining some basic physical and mechanical properties of the soil, such as the deformation modulus of the soil, the allowable bearing capacity of the soil, etc., by systematically measuring the penetration resistance of the soil.
[0003] In engineering investigations, static cone penetration is not only an in-situ testing method but also an important exploration method. Compared with conventional exploration procedures such as drilling - sampling - laboratory testing, it has the characteristics of being fast, accurate, economical, and labor-saving, and is widely used for dividing soil layers, obtaining engineering property indexes of each soil layer, and determining pile foundation parameters, etc.
[0004] The length of the penetration rod for waterborne static cone penetration is approximately the sum of the water depth and the hole depth. In the past, when conducting static cone penetration at sea, if it was necessary to penetrate into a cobblestone or sand and pebble layer, the hole depth needed to reach approximately 70 - 80 m. Adding the water depth and the platform height of about 30 m, the total length of the penetration rod could reach about 100 m, and multiple punching operations were required. The specifications of the penetration rods for static cone penetration are only one meter per rod. When lowering the rod, a new rod needs to be connected every one meter, and when lifting the rod, the rods need to be removed one by one every one meter. For example, it takes 3 - 4 hours to install about 100 m of penetration rods, resulting in low work efficiency and expensive daily boat fees, further increasing the production cost of waterborne static cone penetration operations.
[0005] The existing waterborne static cone penetration in our country usually adopts: (1) For small rivers and creeks, turning them into quasi-land exploration through local backfilling and artificial land reclamation; (2) Using the test pile platform in the project for testing. At this time, the soil layer is disturbed by pile driving, and the obtained static cone penetration data can no longer reflect the natural condition of the soil layer, with large errors; (3) Using a special waterborne static cone penetration test platform for testing; (4) Conducting static cone penetration tests directly on the exploration ship.
[0006] Regardless of which method is adopted, the total length of the required penetration rods is approximately the sum of the water depth and the hole depth, and the specifications of single penetration rods are also the same, which will cause a common problem, that is, the required penetration rod length is long, while the length of a single penetration rod is limited. This makes the operation efficiency of waterborne static cone penetration low and further increases the cost of waterborne exploration operations. Content of the Utility Model
[0007] To solve the problems existing in the above-mentioned prior art, the utility model provides an improved device for a waterborne static cone penetration rod system to solve the problem that the penetration rods required in the existing waterborne static cone penetration construction are long, while the length of a single penetration rod is limited.
[0008] To achieve the above object, the technical solution of the utility model is as follows:
[0009] An improved device for a waterborne static cone penetration sounding rod system, comprising an operation platform, a sounding rod basket, a plurality of sounding rods, and a cross-shaped frame, a placement cage, a drilling rig, and a hydraulic static cone penetrometer placed on the operation platform. The drilling rig is equipped with a winch, and the steel wire rope on the winch bypasses the top of the cross-shaped frame and is connected to the sounding rod basket to assist in lifting the sounding rod for static cone penetration. The sounding rod for static cone penetration is lowered through the hydraulic static cone penetrometer, and the idle sounding rods are placed in the placement cage.
[0010] As a preferred technical solution, a roller is provided at the top of the cross-shaped frame, and the steel wire rope bypasses the roller and is connected to the sounding rod basket.
[0011] As a preferred technical solution, the length of the sounding rod is 3 - 4 meters.
[0012] As a preferred technical solution, the top of the placement cage is provided with an opening, the periphery is made of horizontal and vertical steel pipes, and the bottom is a grid-shaped channel steel. The lower part of the idle sounding rod is stuck in the gap of the grid-shaped channel steel.
[0013] As a preferred technical solution, a telescopic connecting pipe is provided at the middle position in the vertical direction of the placement cage, and the telescopic connecting pipe is detachably connected to the vertical steel pipe.
[0014] As a preferred technical solution, the device further includes a mud pump used in cooperation with the drilling rig.
[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0016] The improved device for the waterborne static cone penetration sounding rod system of the utility model has a simple structure, is flexible in installation and disassembly, and is convenient for transportation; the manufacturing cycle of the components is short, the cost is low, which is conducive to economic savings; the replacement of a single component can be realized, which is convenient for sustainable use of resources. It can solve the problem that the sounding rod required for construction is long during the existing waterborne static cone penetration construction, while the length of a single sounding rod is limited. By increasing the length of the sounding rod, problems such as difficulties in lifting and lowering the rod and insufficient stability of sounding rod placement caused by the increase in the length of the sounding rod are solved by using a cross-shaped frame, a basket, and a placement cage, improving the operation efficiency of waterborne static cone penetration, reducing the cost of waterborne exploration, saving manpower, and providing soil physical and mechanical parameters and engineering property indexes more quickly and accurately to meet the needs of the development of waterborne construction projects.

[0022] As Figure 1 shown, an improved device for a waterborne static cone penetration rod system includes an operation platform 1, a rod basket 7, a plurality of rods 8, and a cross-shaped frame 2, a placement cage 3, a drilling rig 4, and a hydraulic static cone penetrometer 5 placed on the operation platform 1. The drilling rig 4 is equipped with a winch, and the steel wire rope on the winch passes around the roller at the top of the cross-shaped frame 2 and is connected to the rod basket 7 to assist in lifting the rod 8 for static cone penetration. The rod 8 for static cone penetration is lowered into the soil layer through the hydraulic static cone penetrometer 5, and the idle rod 8 is placed in the placement cage 3. The placement cage 3 is used to place and fix the rod 8, which can save space and facilitate the lifting and lowering of the rod 8 after shifting to the next hole position.

[0025] As Figure 2 shown, the placement cage 3 is about 2.9 m high, and the top of the placement cage 3 is open, with horizontal and vertical steel pipe supports arranged around it. As Figure 3 shown, the bottom is a grid-shaped channel steel, and the lower part of the idle rod 8 is stuck in the gap of the grid-shaped channel steel, ensuring the fixation of the rod 8 while not damaging the internal connection wires of the rod 8. In this embodiment, the placement cage 3 includes: 5 #8 channel steels 9, 30 φ50×5 steel pipes 10, 4 connecting pipes 11, 10 5-mm steel plates 12, 10 φ50×2.5 steel pipes 13, and 10 5-mm triangular plates 14. The 5-mm triangular plates 14 are used to enhance the structural strength of the placement cage 3. The #8 channel steels 9 are located at the bottom of the placement cage 3, and the gaps between the #8 channel steels 9 are used to place the rod 8. The remaining parts play a connecting role.
[0026] The middle position of the vertical placement cage 3 is provided with a telescopic connecting pipe 11, and the telescopic connecting pipe 11 is detachably connected to the vertical steel pipe, so that the height of the placement cage 3 can be adjusted, and the placement cage 3 can also be split into upper and lower parts for convenient transportation.
