Description

Technical Field

[0001] This invention belongs to the field of underwater construction technology, specifically relating to a precision throwing and filling device for underwater membrane bag concrete construction. Background Technology

[0002] Underwater membrane bag concrete construction is a common underwater engineering reinforcement technology. Its core involves sinking a specialized membrane bag filled with fluid concrete into a predetermined underwater location. After the concrete solidifies inside the membrane bag, it forms a protective or reinforced structure with a certain strength and integrity. It is widely used in hydraulic and marine engineering projects such as dams, revetments, and foundation erosion control. This technology, with its advantages of convenient construction and adaptability to underwater environments, has become an effective means of addressing underwater structural problems.

[0003] However, in actual construction, the complex underwater environment, including factors such as currents, waves, water depth, and low visibility, coupled with the heavy weight and difficulty in precisely controlling the fluidity of concrete, makes the membrane bags prone to drifting, tumbling, or folding during placement and filling. Existing methods rely heavily on the experience of construction personnel, lacking effective and precise positioning and placement control measures, resulting in the membrane bag concrete often failing to be accurately positioned within the designated area. This deviation not only affects the forming quality and appearance of the structure but may also weaken its protective performance and even pose a threat to the overall safety and durability of the project, becoming a significant bottleneck restricting the improvement of this technology's application effectiveness. Therefore, we propose a precise placement device for underwater membrane bag concrete construction to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that during the current underwater membrane bag concrete construction, it is difficult to accurately pour the membrane bag concrete into the designated area, resulting in deviations in the position of the formed structure and affecting the quality of the project.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A precision dumping device for underwater membrane bag concrete construction includes a hull, a digging mechanism mounted on the hull for drilling underwater rock strata and excavating pits, and a positioning mechanism for assisting in dumping membrane bag concrete. The positioning mechanism includes two steel cables, a sliding component for hoisting and dumping membrane bag concrete, and a counterweight fixedly installed at the lower end of the two steel cables. The sliding component is movably mounted on the two steel cables, and the hull is equipped with a hoisting mechanism for winding and lowering the steel cables.

[0007] Further specifying, the digging mechanism includes a hoisting rope, a fixed base fixedly installed at the lower end of the hoisting rope, multiple support columns fixedly installed at the lower part of the fixed base, and a drill bit. An electric hoist is installed inside the hull, the upper end of the hoisting rope is connected to the output end of the electric hoist, a drive motor is installed inside the fixed base, and the drill bit is fixedly installed on the output shaft of the drive motor. This structural design allows the electric hoist to lower the fixed base and drill bit to the bottom of the water for underwater drilling and digging operations.

[0008] Furthermore, the support column is a hydraulic rod, and its lower end is equipped with a motor-driven wheel. This structural design, with the wheel in conjunction with the hydraulic rod, facilitates the excavation of pits of a predetermined size underwater.

[0009] Further specifying, the sliding assembly includes a sliding block, a fixed block fixedly installed at one end of the sliding block, an L-shaped fixing buckle fixedly installed on the fixed block, a movable buckle adapted to the L-shaped fixing buckle, and a compression spring. The sliding block has two through holes for the steel cable to pass through. The fixed block has an installation groove. The movable buckle is movably installed in the installation groove. The compression spring is fixedly installed between the movable buckle and the groove wall. A hanging ring is fastened between the L-shaped fixing buckle and the movable buckle. A bag for placing the membrane bag concrete is fixedly connected to the hanging ring. This structural design facilitates locking the hanging ring through the L-shaped fixing buckle and the movable buckle.

[0010] Further specifying, the lower end of the fixing block has an insertion hole communicating with the mounting groove, a wedge is fixedly installed on the movable buckle, and a top column adapted to the wedge is fixedly installed on the upper end of both the counterweight block and the fixing block. With this structural design, when the sliding component moves down and contacts the counterweight block or an adjacent sliding component, the top column will push open the movable buckle through the wedge, facilitating the filling of the membrane bag concrete.

[0011] Further defining the sliding block, it comprises a first locking block connected to a fixed block and a second locking block rotatably connected to the first locking block. The second locking block has a slot, and the first locking block has a movable groove. A locking block adapted to the slot is movably installed in the movable groove. A post is fixedly installed on the locking block, with one end extending to the other end of the first locking block. A pull ring is movably installed on one end of the post extending through the first locking block. A return spring is fitted on the post between the locking block and the wall of the movable groove. This structural design allows the return spring, in conjunction with the locking block, to engage and lock the first and second locking blocks, facilitating the clamping of the entire sliding assembly onto the steel cable.

[0012] Furthermore, the perforated hole wall is provided with several grooves, and movable balls are movably installed in several of these grooves. This structural design reduces the frictional resistance between the sliding block and the steel cable through the movable balls, resulting in smoother sliding.

[0013] Further specifying, the hoisting mechanism includes a support frame fixedly mounted on the hull, a rotating roller rotatably mounted on the support frame, and a hoisting motor fixedly mounted on the hull for driving the rotating roller to rotate. The rotating roller is fixedly connected to the upper ends of two steel cables. This structural design is simple and easy to use.

[0014] Furthermore, the lower end of the counterweight is fixedly equipped with multiple anchoring spikes, and a scanner for scanning underwater topography is also provided at the lower end of the counterweight. This structural design allows for the scanning and identification of underwater topography, making excavation or filling operations more precise.

[0015] The invention employing the above technical solution has the following advantages:

[0016] The present invention provides a pit-digging mechanism that can excavate a pit of a set size underwater. Through steel cables and sliding components, the membrane bag concrete can be hoisted into the underwater pit. When the sliding component slides to the bottom or contacts the previously deployed sliding component, the membrane bag concrete can be automatically detached, making the filling process more precise and faster.

[0043] like Figures 1 to 7 As shown, a precision throwing and filling device for underwater membrane bag concrete construction according to the present invention includes a hull, a digging mechanism 1 installed on the hull for drilling underwater rock strata and digging pits, and a positioning mechanism 2 for assisting in the throwing and filling of membrane bag concrete. The positioning mechanism 2 includes two steel cables 21, a sliding component 22 for hoisting and throwing membrane bag concrete, and a counterweight 23 fixedly installed at the lower end of the two steel cables 21. The sliding component 22 is movably installed on the two steel cables 21. A hoisting and lowering mechanism 3 for winding and lowering the steel cables 21 is provided on the hull.

[0044] The digging mechanism 1 includes a hoisting rope 11, a fixed base 12 fixedly installed at the lower end of the hoisting rope 11, multiple support columns 13 fixedly installed at the lower part of the fixed base 12, and a drilling head 14. An electric hoist is installed inside the hull. The upper end of the hoisting rope 11 is connected to the output end of the electric hoist. A drive motor is installed inside the fixed base 12. The drilling head 14 is fixedly installed on the output shaft of the drive motor. The support columns 13 are hydraulic rods, and the lower end of the support columns 13 is provided with a motor-driven traveling wheel 131. The traveling wheel 131 can drive the fixed base 12 and the drilling head 14 to move underwater as a whole, which is convenient for adjusting the drilling area.

[0045] The sliding component 22 includes a sliding block 221, a fixing block 222 fixedly installed at one end of the sliding block 221, an L-shaped fixing buckle 223 fixedly installed on the fixing block 222, a movable buckle 224 adapted to the L-shaped fixing buckle 223, and a compression spring 225. The sliding block 221 has two through holes for the steel cable 21 to pass through. Several grooves are formed on the wall of the through holes. Movable balls 2215 are movably installed in the grooves. The fixing block 222 has an installation groove 2221. The movable buckle 224 is movably installed in the installation groove 2221. The compression spring 225 is fixedly installed between the movable buckle 224 and the groove wall of the installation groove 2221. A hanging ring 4 is fastened between the L-shaped fixing buckle 223 and the movable buckle 224. A bag 41 for placing the membrane bag concrete is fixedly connected to the hanging ring 4.

[0046] The lower end of the fixed block 222 is provided with an insertion hole 2222 that communicates with the mounting groove 2221. A wedge block 2241 is fixedly installed on the movable buckle 224. The upper ends of the counterweight block 23 and the fixed block 222 are both fixedly installed with top posts that are compatible with the wedge block 2241. Multiple fixing spikes are fixedly installed at the lower end of the counterweight block 23 to improve the stability of the counterweight block 23. A scanner for scanning the underwater topography is provided at the lower end of the counterweight block 23.

[0047] The sliding block 221 consists of a first locking block connected to the fixed block 222 and a second locking block rotatably connected to the first locking block. The second locking block has a slot, and the first locking block has a movable slot. A locking block 2211 adapted to the slot is movably installed in the movable slot. A pin 2212 is fixedly installed on the locking block 2211. The end of the pin 2212 extends to the other end of the first locking block. A pull ring 2213 is movably installed on one end of the pin 2212 that extends through the first locking block. A return spring 2214 is sleeved on the pin 2212 between the locking block 2211 and the wall of the movable slot. The locking block 2211 can be pulled away from the slot by the pin 2212, which facilitates the adjustment of the rotation state of the first and second locking blocks.

[0048] The hoisting mechanism 3 includes a support frame 31 fixedly installed on the hull, a rotating roller 32 rotatably installed on the support frame 31, and a hoisting motor 33 fixedly installed on the hull for driving the rotating roller 32 to rotate. The rotating roller 32 is fixedly connected to the upper ends of two steel cables 21. When the rotating roller 32 rotates, it can complete the winding or lowering of the two steel cables 21, which facilitates the hoisting of the counterweight 23 and the sliding component 22 on the steel cables 21.

[0049] The method of using this invention is as follows:

[0050] When in use, the electric hoist lowers the digging mechanism 1 underwater, and the drilling head 14 rotates underwater to complete the drilling work. The support column 13 (hydraulic rod) at the lower end of the fixed seat 12 can adjust the drilling depth of the drilling head 14. After drilling a hole of the set size, the electric hoist works again and lifts the fixed seat 12 and the drilling head 14 upward through the hoisting rope 11.

[0051] The crane motor 33, together with the rotating roller 32, lowers the steel cable 21 and the counterweight 23 to the side of the underwater drilled pit. After the scanner scans the underwater topography and adjusts the placement of the counterweight 23, the steel cable 21 continues to be lowered until the fixing spike at the lower end of the counterweight 23 is inserted into the underwater soil, and the position of the counterweight 23 is locked.

[0052] The crew on the ship assembles the sliding component 22 onto the steel cable 21 (the first locking block and the second locking block are unfolded so that the two steel cables 21 are respectively located at the through holes of the first locking block and the second locking block, and then the second locking block is pushed towards the first locking block so that the locking block 2211 is locked into the slot under the elastic force of the return spring 2214, and the first locking block and the second locking block are engaged), hangs the hanging ring 4 between the L-shaped fixed buckle 223 and the movable buckle 224, and then throws the bag 41 downward. The bag 41 falls downward along the steel cable 21 with the cooperation of the sliding component 22 and the steel cable 21.

[0053] When the sliding block 221 contacts the upper end of the counterweight block 23 (when it is placed later, the sliding block 221 will contact the upper end of the sliding block 221 placed below first), the top column extends into the insertion hole 2222 and the mounting groove 2221, pushing the wedge block 2241 and the movable buckle 224 into the depth of the mounting groove 2221. At this time, an opening appears at the junction of the movable buckle 224 and the L-shaped fixing buckle 223, and the hanging ring 4 will detach under the action of gravity, and the bag 41 and the membrane bag concrete will fall smoothly into the pit.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
