Description

Technical Field

[0001] The utility model relates to the field of engineering investigation, and particularly relates to a floating box type crawler walking mudflat dual-purpose static cone penetration platform. Background Technique

[0002] In the construction of coastal engineering such as ports, bridges, and wind power, engineering investigation must involve mudflat areas. Mudflats, which are the general terms for beaches, river beaches, and lake beaches, refer to the tidally inundated areas between the high tide level and the low tide level of the coastal area, and are called "intertidal zones" in geomorphology. Due to the action of tides, mudflat areas are characterized by being submerged at high tide and exposed at low tide, usually with loose soil and low bearing capacity.

[0003] In engineering investigation, 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 and sampling and laboratory tests, 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.

[0004] Static cone penetration tests are carried out using lifting platforms both on land and on water, but in mudflat areas, the implementation of static cone penetration is extremely difficult. Traditionally, methods such as piling sandbags or building scaffolds are mostly used to build fixed working platforms, which are difficult to relocate, have low efficiency, and are extremely unsafe; if a shipborne exploration platform is used, the exploration operation will be affected by tides and the draft depth of the ship - when the tide ebbs, the water level dries up and the ship cannot move; when the tide rises, if the water level does not reach the floating water level of the ship and cannot meet the draft depth of the ship, it cannot reach the position, and the construction progress is difficult to control manually. In addition, there are still exploration blind spots where roads cannot be built, vehicles cannot reach, and ships cannot enter at the water-land junction at low tide or in muddy mudflat areas, causing great difficulties to the exploration work.

[0005] With the continuous improvement of the quality requirements for coastal and offshore hydraulic buildings, cross-sea bridges and tunnels, deep-water wharves, offshore wind power, coastal defense projects, etc., the requirements for the investigation of mudflat areas in geotechnical engineering foundation design are also getting higher and higher.

[0013] As a preferred technical solution, the connection assembly includes eight sets of first connection units and two sets of second connection units. Each floating box is fixedly connected to the operating device through two sets of first connection units. The first connection unit includes a support bracket, a support bracket connecting rod and a pressing plate.

[0022] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0023] like Figure 1 As shown, a pontoon-type crawler-type dual-purpose static penetration platform for tidal flats includes an operating device 1, a buoyancy device, a power device and a connecting assembly. The buoyancy device includes four pontoons respectively arranged on the front, rear, left and right sides of the operating device 1. The buoyancy device is connected to the operating device 1 through a connecting assembly. The power device includes a ship-type propeller 14 and a crawler-type walking device. The crawler-type walking device is a device that comes with the operating device 1.

[0024] The four pontoons can provide a maximum buoyancy of approximately 10.40 tons, and the draft depth can be adjusted by adding water to the pontoons; when there is a greater demand for buoyancy, foam air bags can be attached to the outside of the pontoons.

[0025] There are railing bases 7 on the four floating boxes. During construction, guardrails are installed on the railing bases 7 to protect the safety of operators.

[0026] The operation device 1 is an in-situ testing device mainly used for static cone penetration or vane shear test, etc., and can also be replaced by a drilling and sampling device.

[0027] As Figure 2 shown, a marine paddle machine 14 is provided at the tail of the platform. As a power device for walking on water, it includes a paddle machine frame, an engine, a propeller, a rudder blade and a controller. The marine paddle machine 14 is fixed on the rear floating box 4 through the paddle machine frame. The controller controls the steering of the rudder blade, thereby changing the traveling direction of the platform on the water and facilitating the movement on the water; the crawler walking device is a power device for walking on land.

[0028] The connecting component includes eight sets of first connecting units and two sets of second connecting units. Each floating box and the operation device 1 are fixedly connected through two sets of first connecting units. As Figure 3 shown, the first connecting unit includes a support bracket 10, a support bracket connecting rod 12 and a pressing plate 13. The pressing plate 13 and the support bracket 10 are welded on the side wall of the floating box. The pressing plate 13 is arranged above the support bracket 10. The lower surface of the pressing plate 13 is flush with the top surface of the floating box. There is a gap between the pressing plate 13 and the support bracket 10 to buckle onto the operation device 1. The support bracket connecting rod 12 passes through the reserved holes on the pressing plate 13, the operation device 1 and the support bracket 10 in sequence to connect the floating box and the operation device 1.

[0029] The left floating box 3 and the right floating box 5 are strengthened and fixed to the operation device 1 through the second connecting unit to prevent the connection deformation and overturning of the floating box caused by water flow scouring. The second connecting unit includes two upper and lower 8# channel steels 8 and two left and right channel steel connecting rods 11 connected in a "well" shape.

[0030] The floating box type crawler walking and beach dual-purpose static cone penetration platform further includes a support and fixing component. The support and fixing component includes four support legs 9 and four ground anchor holes 6. The support legs 9 are provided with hydraulic devices, and the length of the support legs 9 can be adjusted through the hydraulic devices, thereby realizing the leveling of the operation platform. The ground anchor is lowered through the ground anchor hole 6. The ground anchor can adjust its length by replacing the anchor rods of different lengths, and adjust the contact area with the formation by replacing different anchor plates to provide different reaction forces to help fix the platform.

[0031] Any of the above devices and components can be replaced in case of damage, thereby effectively extending the service life of this floating box type crawler walking and beach dual-purpose static cone penetration platform.

[0032] A working method of a floating box type crawler walking and beach dual-purpose static cone penetration platform includes the following steps:

[0033] After transporting each component in pieces to the site, they are connected on-site to assemble a floating box type crawler walking beach and mudflat dual-purpose static cone penetration platform;

[0034] When the static cone penetration platform is located in the land area or the water level of the beach is relatively low, it travels through the crawler walking device. After reaching the predetermined working position, the support leg 9 is lowered, and the length of the support leg 9 is adjusted through the hydraulic device to make the working platform reach a horizontal working surface. The ground anchor is lowered through the ground anchor hole 6 to provide the reaction force required for the operation of the working device 1;

[0035] When the static cone penetration platform is located in the water area or the water level of the beach rises, the platform is floated by four floating boxes. When the buoyancy is insufficient, foam air bags are added around the floating boxes to increase the buoyancy of the platform. The marine oar engine 14 provides the power for water travel, and the platform sails to the predetermined working position. The ground anchor is lowered through the ground anchor hole 6 and inserted into the seabed to fix the platform and provide the reaction force required for the operation of the working device 1.

[0036] This embodiment is only a further explanation of the present utility model, rather than a limitation to the present utility model. Those skilled in the art can make non-creative modifications to this embodiment according to needs after reading this specification. However, as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
