Description

Technical Field

[0001] The invention relates to the technical field of marine slideway engineering, and in particular to a novel force transmission joint structure of a marine slideway. Background Art

[0002] Large horizontal forces will be generated during the shipping of offshore products, and as product specifications continue to improve, the horizontal forces will also become larger and larger, and the slideway structure will be subjected to huge horizontal forces. Especially in the case of pile foundation slideways, it will have a greater impact on the force of the pile foundation, thereby increasing the pile diameter, the number of pile foundations, the reinforcement ratio of the pile foundation, and the project cost.

[0003] In the prior art, the gap between the two slide blocks is directly filled with elastic material. The gap structure cannot fully transmit the horizontal force of the slide, causing uneven force on the pile foundation, resulting in an inability to adapt to higher product requirements. Summary of the invention

[0004] The purpose of the present invention is to provide a force transmission joint structure of a marine engineering slide in view of the deficiencies in the prior art. The force transmission joint structure of the marine engineering slide is composed of a "V"-shaped notch on the upper part of the slide block and an expansion joint below the same. The joints of the slide blocks are filled with elastic materials, and the upper notches are filled with steel wedge-shaped blocks. Embedded plates are arranged on both sides of the notches. The force transmission joint structure is simple. On the basis of the original slide joints, the shape of the joints is changed, and wedge-shaped blocks are added for filling the joints, so that the slide structure can be better connected as a whole. At the same time, it can reduce the impact of construction in different seasons on large-volume concrete, can withstand greater horizontal forces, has better adaptability to products, has a simple structure, low engineering cost, convenient construction, flexible use, further improved production capacity and economic benefits, and has good application prospects.

[0005] The specific technical scheme for achieving the purpose of the present invention is: a force transmission joint structure of a marine slideway, comprising a plurality of slideway blocks A and B arranged on the marine slideway, wherein the slideway block A is a concrete block provided with a trapezoidal boss, and the slideway block B is a concrete block provided with a trapezoidal groove, wherein the slideway block A is embedded in the trapezoidal groove of the slideway block B by the trapezoidal boss, and a "V"-shaped expansion joint is provided on the upper part of the joint, and the expansion joint on the upper part of the joint is made of steel The wedge-shaped block is used for caulking, and the expansion joint at the bottom of the joint is filled with elastic caulking material; the "V"-shaped notch, the steel wedge-shaped block and the elastic caulking material together constitute the force transmission joint structure of the marine engineering slideway; the top of the A slideway block and the B slideway block is provided with embedded steel plates; the embedded steel plates are arranged on the top surfaces of the slideway blocks on both sides of the "V"-shaped notch; the steel wedge-shaped block is embedded in the "V"-shaped notch for caulking, and its two sides are in contact and flush with the embedded steel plates.

[0006] A steel pull ring is provided on the top of the steel wedge-shaped block. When the marine slideway is in use, the steel pull ring is used to put the steel wedge-shaped block into the "V"-shaped notch so that it fits and is flush with the embedded steel plate.

[0007] Compared with the prior art, the present invention improves the horizontal force transmission between slides. For a slide structure based on pile foundations, it can effectively share the horizontal force of each pile and reduce the reinforcement amount of the pile foundation. The "V"-shaped notch joint structure setting can reserve a larger space, reduce the internal temperature rise of the large-volume concrete of the slide, release the temperature stress inside the large-volume concrete of the slide and the temperature displacement changes caused by construction in different seasons. The structure is simple, the construction is convenient, and the use is flexible. The corresponding filling materials can be adjusted according to different products to better adapt to different projects. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] See also Figure 1-2 The present invention is composed of a slide block A 1, a slide block B 2, an elastic caulking material 3, and a steel wedge-shaped block 5. The slide block A 1 is embedded in the trapezoidal groove 21 of the slide block B 2 by a trapezoidal boss 11, and a "V"-shaped notch 7 expansion joint is arranged on the upper part of the split 8. The "V"-shaped notch 7, the steel wedge-shaped block 5 and the elastic caulking material 3 together constitute the force transmission joint structure of the marine slideway. The expansion joint on the upper part of the split 8 is caulked with the steel wedge-shaped block 5, and the expansion joint on the lower part of the split 8 is caulked with the elastic caulking material 3; the tops of the slide blocks A 1 and B 2 are provided with embedded steel plates 4; the embedded steel plates 4 are arranged on the top surfaces of the slide blocks on both sides of the "V"-shaped notch 7; the steel wedge-shaped block 5 is embedded in the "V"-shaped notch 7 for caulking, and its two sides are in contact with and flush with the embedded steel plates 4.

[0015] See also Figure 3-4The A slide block 1 is a concrete block with a trapezoidal boss 11, and the B slide block 2 is a concrete block with a trapezoidal groove 21.

[0016] See also Figure 5-6 A steel pull ring 6 is provided on the top of the steel wedge-shaped block 5. When the marine slide is in use, the steel pull ring 6 is used to put the steel wedge-shaped block 5 into the "V"-shaped notch 7 so that it fits with the embedded steel plate 4.

[0017] The present invention determines the size of the "V"-shaped notch 7 at the upper part of the split according to the specifications of the marine engineering product before construction. When constructing the slide block, the embedded steel plates 4 are pre-buried on both sides and the top of the notch, and then the steel wedge-shaped blocks 5 matching the notch are manufactured according to the size of the notch. When the product is shipped, the steel wedge-shaped blocks 5 are placed in the notch, and after the shipment is completed, the steel wedge-shaped blocks 5 are taken out. The present invention uses the steel wedge-shaped blocks 5 as the main caulking material of the split 8 to effectively improve the horizontal force transmission between the slides, and can effectively share the horizontal force of each pile for the slide structure based on the pile foundation, reducing the reinforcement amount of the pile foundation. At the same time, the "V"-shaped notch 7 is configured to change the shape of the joints on the basis of the original slide joints, thereby reserving a larger space, greatly reducing the temperature rise inside the large-volume concrete of the slide, releasing the temperature stress inside the large-volume concrete of the slide and the temperature displacement changes caused by construction in different seasons, and adding wedge blocks for filling the joints, so that the slide structure can be better connected as a whole, while reducing the impact of construction in different seasons on the large-volume concrete.
