Description

Technical Field

[0001] The invention relates to the technical field of containment plate construction, and in particular to a construction device and a construction method for performing underwater operations on containment plates. Background Art

[0002] Huge waves, floods, mudslides and other natural disasters often cause great damage to ports, coasts, riverbanks, buildings, personnel, etc. For this reason, people have invented artificial dikes to prevent wave invasion, protect coasts, and protect riverbanks. The sheet piles currently used in the market for building dikes have the following main disadvantages: First, most of them are made of steel metal materials, which are easily corroded and rusted after being immersed in water for a long time, which poses a safety hazard and is not conducive to environmental protection; second, the cost is high, which is not conducive to popularization and application; third, the connection structure is relatively simple, usually only extending to both sides into a straight shape, and it is not easy to connect into various shapes according to actual needs, such as right-angle corners, squares, T-shaped structures, etc., which makes the application not convenient and flexible. In addition, the walls, swimming pools and other projects currently used are all made of bricks, which are not only complicated to construct, but also permanent once completed, and cannot be relocated, but can only be dismantled and scrapped, and the dismantled materials can only be discarded and cannot be reused. In short, the technical solutions currently used in such projects have both safety issues and problems such as inconvenient construction, slow progress, low construction efficiency, long construction period, and single function.

[0003] Containment panels are also called sheet piles. They are made of plastic and are composed of multiple plastic sheet piles connected to each other. Connectors are provided at both ends of the sheet piles. Adjacent sheet piles are connected together by inserting corresponding intermediate connectors through the connectors, or connected to each other through the sheet piles' own connectors. Sheet piles are connected at corners by cross connectors, T-shaped connectors or right-angle connectors. Made of plastic, they will not corrode or rust. They are connected through sheet pile connectors or intermediate connectors, and various corner structures are formed by S-shaped connectors and double G-shaped connectors, or cross connectors, T-shaped connectors, right-angle connectors, right-angle hook connectors, etc. The overall structural performance is good, and they are resistant to corrosion, leakage, and earthquakes. They can be used to build seawalls and dams to block waves, floods, landslides, mudslides, etc. They can also be used in the construction of walls, swimming pools, simple houses, etc. They have the advantages of convenient construction, improved work efficiency, and reduced project costs.

[0004] It is widely used. The current products are all exposed to the water surface during construction. However, as the use scenarios of the products change, they are mainly used to prevent water and soil erosion in the wading part of the river or coastline, but the containment plate does not need to be exposed to the water surface. For underwater operations, robots are currently required to assist, and the operation cost is too high, which is not suitable for general underwater engineering operations. Now there is no problem with the construction of products exposed to the water surface, but how to operate underwater has become a big problem. Summary of the invention

[0005] In order to solve the above-mentioned technical deficiencies, the present invention provides a construction equipment and a construction method for underwater operations on a containment plate. The two ends of the containment plate are connected to each other in a cooperative manner, that is, the connecting head at one end and the groove at the other end can be snap-connected. The containment plate body between the containment plate connecting head and the connecting groove can be a flat surface or a special-shaped structure, and the operation can be carried out all year round.

[0006] The present invention designs a construction equipment for underwater operation of containment plates, which includes a pile driver head connecting piece and a containment plate fixing piece. A guide piece is also provided between the pile driver head connecting piece and the containment plate fixing piece, one end of the guide piece is connected to the containment plate fixing piece, and the other end of the guide piece is connected to the pile driver head connecting piece; the containment plate fixing piece is provided with a locking mechanism to prevent the containment plate from falling down during operation; a guide groove is provided on the guide piece along the length direction; a connecting groove is provided on one side of the containment plate fixed on the containment plate fixing piece, the guide groove on the guide piece and the connecting groove on the containment plate are both located on the same side and are opposite to the connecting groove in the length direction, so that the connecting head of the latter containment plate can smoothly slide into the connecting groove of the guide piece of the former construction equipment after entering the guide groove during construction.

[0007] In order to quickly position and fix the containment plate, a guide part is provided at the upper end of the containment plate fixing piece. The lower end opening of the guide part is large, the upper end opening is small, and the inner bottom end surface of the guide part is located in the same plane.

[0008] In order to prevent the containment plate from falling down, the locking mechanism can be as follows: a through hole is provided at the upper end portion of the containment plate fixing piece, and a through hole corresponding to the through hole of the containment plate fixing piece is also provided on the containment plate. The through hole on the containment plate fixing piece and the through hole on the containment plate are fixed by bolts and nuts, or by a latch. The free end of the latch has a hole, and the hole of the latch can be prevented from falling out of the through hole by inserting an insert, such as a steel wire, a steel nail, etc.; an L-shaped component can also be inserted in the through hole, and the other end of the L-shaped component can pass through the containment plate and the containment plate fixing piece. A through hole, a hole is provided at the end of the passing end of the L-shaped member, the hole of the L-shaped member is for the hook-shaped body to hook, and the other end of the hook-shaped body is preferably fixed to the guide member by a tension spring; an L-shaped member can also be inserted in the through hole, one end of the L-shaped member can be inserted into the through hole of the containment plate and the containment plate fixing member, a circular hole is set at the passing end of the L-shaped member, a long hole is set on the side of the circular hole, the long hole is connected to the circular hole, the width of the long hole is smaller than the diameter of the circular hole, and a swinging member is connected to the circular hole through a polygonal pin shaft, and the polygonal pin shaft can rotate in the circular hole, but cannot rotate in the long hole.

[0009] In order to prevent the gap between the containment plate and the containment plate fixings from being too large before the containment plate is driven into the soil layer, causing the driven part to deviate from the predetermined position, the lower end of the containment plate fixings can be clamped with pliers, and after reaching the position, the pliers can be pulled with a rope.

[0010] The locking pliers include a first clamping arm, a second clamping arm, a tension spring, a support rod, a handle and a release plate. An extension portion is extended and fixed at the end of the handle, and an L-shaped release buckle is rotatably connected to the extension portion. One end of the L-shaped release buckle is in contact with the release plate, and a connecting rope is fixed to the other end of the L-shaped release buckle. The other end of the connecting rope is fixed to the end of the first clamping arm, and the rope is connected to the connecting rope.

[0011] The present invention discloses a construction method for underwater operation of a containment plate. In the first step, a first containment plate is arranged on a first containment plate fixing piece, and the construction equipment for underwater operation of the containment plate is detachably connected to a pile driver. Under the action of the pile driver, the first containment plate is driven into a set position depth, and the pile driver is separated from the first construction equipment for underwater operation of the containment plate; in the second step, after the second containment plate is arranged on a second containment plate fixing piece, the second construction equipment for underwater operation of the containment plate is detachably connected to a pile driver head, and under the action of the pile driver, the second containment plate is driven into a set position depth, and the second containment plate is connected to the first containment plate, that is, the connecting head of the second containment plate is inserted into the connecting groove of the first containment plate, and the two form a connection. Then the pile driver is separated from the second construction equipment for underwater operation on the containment plate; the third step is that the pile driver connects to the first construction equipment for underwater operation on the containment plate, separates the containment plate from the construction equipment for underwater operation on the containment plate, and inserts the separated construction equipment for underwater operation on the containment plate into a new containment plate, and the position of the new containment plate is driven into the set depth by the pile driver and the new containment plate is connected with the most recently driven containment plate, and the pile driver is separated from the construction equipment for underwater operation on the containment plate, and the above steps are repeated continuously; the fourth step is that after the construction of the last containment plate is completed, the pile driver pulls out the remaining construction equipment for underwater operation on the containment plate according to the rule of first in first out, and the construction is completed after all the pulling out is completed.

[0012] In order to make it easier to drive into the soil during construction, the length of the containment plate fixings is longer than the length of the containment plate. It is more appropriate to be about 5 cm longer, taking both economy and practicality into consideration.

[0013] The construction equipment and construction method for underwater operations on containment plates obtained by the present invention can be connected to the containment plates and press the containment plates below the water surface. When the rear containment plates are driven in, the previous construction equipment for underwater operations on the containment plates is retained on the front containment plates. The guide groove of the construction equipment for underwater operations on the containment plates is exposed on the water surface, so that the connecting head of the rear containment plate can be inserted into the guide groove and pressed down into the connecting groove of the front containment plate, so as to facilitate the docking between the two containment plates and realize underwater operations.

[0014] The present invention has the characteristics of being able to realize underwater operations without the assistance of robots and being able to operate at any time without being affected by the weather, and the operating efficiency is improved by more than 20% compared with the current level. In addition, the present invention also has the characteristics of simple construction equipment structure and convenient construction operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The containment plate 7 is an existing known product, that is, a sheet pile, one end of the body in the width direction of which is a connecting head 72, and the other end is a connecting groove 71. When the containment plate 7 is in use, two adjacent containment plates 7 are butted together, that is, the connecting head 72 of one containment plate 7 is inserted into the connecting groove 71 of another containment plate 7. The shape of the above-mentioned containment plate fixing member 2 is similar to the shape of the body of the containment plate 7, that is, when the containment plate fixing member 2 and the containment plate 7 are butted together, the two fit together. The guide member 3 is provided with a guide groove 31, and the guide groove 31 needs to be connected with the connecting groove 71 of the containment plate 7 fixed on the containment plate fixing member 2.

[0041] like Figure 1-Figure 6 As shown, the present invention discloses a construction equipment for underwater operation of a containment plate, including a pile driver head connecting member 1 and a containment plate fixing member 2, a guide member 3 is further provided between the pile driver head connecting member 1 and the containment plate fixing member 2, one end of the guide member 3 is connected to the containment plate fixing member 2, and the other end of the guide member 3 is connected to the pile driver head connecting member 1; the containment plate fixing member 2 is used to connect the containment plate 7, and is also provided with a locking mechanism to prevent the containment plate 7 from falling down during operation; a guide groove 31 is provided on the guide member 3 along the length direction, and the guide groove 31 is connected to the connecting groove 71 at the end of the containment plate 7 fixed on the containment plate fixing member 2.

[0042] A guide part 5 is provided at the upper end of the containment plate fixing part 2, and the guide part 5 is opposite to the containment plate 7. The lower end opening of the guide part 5 is large, and the upper end opening is small. The inner bottom surface of the guide part 5 is flat, and the top end of the containment plate 7 enters the guide part 5 and fits with the inner bottom surface of the guide part 5.

[0043] In order to prevent the containment plate 7 from falling down, the locking mechanism is as follows: Fig.13 , Fig.14 As shown, it is an L-shaped component 14, the other end of the L-shaped component 14 can pass through the through hole 6 of the containment plate 7 and the containment plate fixing member 2, and the end of the L-shaped component 14 through which it passes has a hole, and the hole of the L-shaped component 14 is for the hook-shaped body 12 to hook, and the other end of the hook-shaped body 12 is preferably fixed to the guide member 3 by a tension spring 13.

[0044] In order to prevent the containment plate 7 from deviating from the set position due to the large gap between the containment plate 7 and the containment plate fixing member 2 before being driven into the soil layer, the lower end of the containment plate fixing member 2 is clamped with a pliers 19. After reaching the position, the pliers 19 are pulled with a rope to retract the pliers 19. The pliers 19 are modified from American C-type pliers produced by Foshan Yingzhiyin Hardware Tools Manufacturing Co., Ltd.
