Description

Technical Field

[0001] The utility model relates to the technical field of the repair of the water stop belt of immersed tubes, in particular to a repair structure for the water stop belt of a dock gate. Background Art

[0002] When adopting the dry dock method to sink tubes in multiple batches, a dock gate is usually arranged at the dock entrance of the dry dock, and the dry dock is reused by opening and closing the dock gate repeatedly for many times.

[0003] At present, the water stop measure at the dock entrance is completed by the cooperation of the dock gate, the dock pier and the water stop belt. The previous water stop belt was generally arranged on the dock gate, moved to the dock pier together with the dock gate, and was extruded and attached to the dock pier to achieve the water stop effect. However, the water stop belt arranged on the dock gate needs to be floated and stored for a certain distance along with the dock gate, which accelerates the loss of the water stop belt, thus causing the problem of poor water stop effect at the dock entrance.

[0004] The Chinese utility model patent with the publication number of CN214194457U discloses a connection structure between a dock pier and a water stop belt. The connection structure between the dock pier and the water stop belt includes a water stop belt and a dock pier. A fixing device is arranged on the dock pier and is used for fixing the water stop belt. A pressing block is arranged on the fixing device. One end of the pressing block extends out of the side surface of the fixing device. The pressing block is arranged at an interval with the dock pier. An installation area for the water stop belt is formed between the part where the pressing block extends out of the side surface of the fixing device and the dock pier; the water stop belt is fixed in the installation area. It abandons the existing setting mode of the water stop belt, fixes the water stop belt on the dock pier, so that the water stop belt will not move along with the dock gate, and further will not accelerate the loss of the water stop belt; moreover, after being matched with the dock gate, it can effectively stop water at the dock entrance. Therefore, it can effectively stop water at the dock entrance after being matched with the dock gate, and will not make the water stop belt move along with the dock gate, and further can increase the service life of the water stop belt. However, for this kind of water stop structure, which includes an arc part in the middle and side wings on both sides, if the side wings of the water stop belt are damaged, the damaged part of the water stop belt cannot be fixed by the pressing block, which will further lead to the instability of the water stop structure and affect the water stop effect. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiency that when the side wings of the water stop belt are damaged in the prior art, the damaged part of the water stop belt cannot be fixed by the pressing block, which will further lead to the instability of the water stop structure and affect the water stop effect, and provide a repair structure for the water stop belt of a dock gate.

[0006] The utility model provides a repair structure for the water stop belt of a dock gate, which includes a fixing structure. The fixing structure is transversely spanned outside the arc structure in the middle of the damaged water stop section along the damaged water stop section. Both ends of the fixing structure are fixed transversely. The fixing structure squeezes and fixes the damaged water stop section to the dock pier.

[0007] Among them, the damaged water stop section is the length part where the damage occurs in the dock pier water stop belt.

[0008] For the repair structure of the dock gate water stop belt in this solution, the damaged water stop section is extruded and fixed to the dock pier through a fixing structure that is horizontally spanned outside the middle arc structure of the damaged water stop section. Even if the flank of the damaged water stop section is damaged, it can still ensure that the damaged water stop section is always fixed to the dock pier, ensuring the water stop effect.

[0009] Preferably, the fixing structure includes several fixing bars that are spaced apart along the length direction of the damaged water stop section and span across the damaged water stop section.

[0010] Using several fixing bars to fix at intervals in the length direction of the damaged water stop section makes the fixing operation more convenient and has a better fixing effect.

[0011] Preferably, the fixing bar is a steel wire, which has a simple structure, is easy to process, is easy to adapt to the middle arc surface of the damaged water stop section, can improve the fixing effect, and is convenient for the fixing operation.

[0012] Preferably, the spacing of the steel wires is 300mm - 500mm. If the spacing is too large, the fixing effect becomes poor, which is not conducive to the water stop effect. If the spacing is too small, the operation is cumbersome.

[0013] Preferably, it includes fixing devices and pressing blocks that are already provided on both sides of the damaged water stop section. The pressing block is connected to the fixing device, and the fixing device is connected to the dock pier. The pressing block is used to press the side of the water stop belt against the dock pier. The steel wires are arranged corresponding to the fixing devices on both sides of the damaged water stop section, and the steel wires are fixed to the pressing block or the fixing device, making the fixing operation of the steel wires more convenient.

[0014] Preferably, the pressing block is fixed to the corresponding side fixing device through fixing bolts, and the steel wire is tied and fixed to the fixing bolts. The steel wire winds around the fixing bolts for 1 - 3 circles, making the fixing operation of the steel wire more convenient and having a better fixing effect.

[0015] Preferably, it further includes a rubber pad, which covers the outside of the middle arc surface of the damaged water stop section, and the fixing structure extrudes and fixes the rubber pad to the outside of the middle arc surface of the damaged water stop section.

[0016] When there are cracks on the outside of the middle arc surface of the damaged water stop section, it greatly affects its water stop effect. By covering the outside of the middle arc surface of the damaged water stop section with a rubber pad and extruding and fixing it through the fixing structure, its water stop effect can be ensured.

[0017] Preferably, the rubber pad includes 2 - 3 pieces, and the 2 - 3 pieces of rubber pads are stacked. The thickness of each rubber pad is 4mm - 6mm.

[0018] If the number of stacked rubber pads is large, the operation is cumbersome. Using 2 - 3 pieces stacked has a better water stop effect. If the thickness of the rubber pad is too small, the water stop effect becomes poor; if the thickness of the rubber pad is too large, it is likely to affect the opening and closing of the dock gate at the dock pier.

[0019] Preferably, both ends in the length direction of the rubber pad exceed both ends of the damaged water stop section, and both ends of the rubber pad overlap on the outer side of the middle arc surface of the intact water stop belt. This can improve the water stop effect.

[0020] Preferably, the overlapping length between both ends of the rubber pad and the intact water stop belt is greater than 300 mm, and the water stop effect is better.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] The present utility model provides a repair structure for the dock gate water stop belt. The damaged water stop section is extruded and fixed to the dock pier through a fixing structure that is horizontally spanned outside the middle arc structure of the damaged water stop section. Even if the side wings of the damaged water stop section are damaged, it can still ensure that the damaged water stop section is always fixed to the dock pier, ensuring the water stop effect.

[0037] Embodiment 1

[0038] As Figure 1 shown, the waterstop is fixed on the dock pier 2. Most of it is a complete waterstop section 13, but there is partial damage to the waterstop. For example Figure 1 the first damaged waterstop section 11 and the second damaged waterstop section 12 in

[0039] As Figure 2 shown, the first damaged waterstop section 11 is mainly damaged on the right wing, resulting in the inability of the right pressing block 5 to tightly press the right side of the waterstop. That is, the damage to the waterstop causes the original fixing structure to be unable to fix, and further leads to a poor waterstop effect at the first damaged waterstop section 11.

[0040] As Figure 3 shown, the second damaged waterstop section 12 mainly has a crack 121 at the center of the middle arc surface. The damage to the waterstop causes the waterstop to leak, resulting in a poor waterstop effect at the second damaged waterstop section 12.

[0041] For the problem of damage at the first damaged waterstop section 11, this embodiment provides a repair structure for the waterstop of the dock door, including a fixing structure. The fixing structure is horizontally spanned along the damaged waterstop section on the outside of the horizontal middle arc structure of the damaged waterstop section. The two ends of the horizontal span of the fixing structure are fixed, and the fixing structure squeezes and fixes the damaged waterstop section to the dock pier 2.

[0042] In the repair structure of the waterstop of the dock door in this solution, the damaged waterstop section is squeezed and fixed to the dock pier 2 through the fixing structure horizontally spanned on the outside of the horizontal middle arc structure of the damaged waterstop section. Even if the wing of the damaged waterstop section is damaged, it can still ensure that the damaged waterstop section is always fixed to the dock pier 2, ensuring the waterstop effect. In this solution, mainly by the fixing structure spanning both sides of the damaged waterstop section, and the two ends of the fixing structure are fixed. The fixing can be directly fixed on the dock pier 2, or fixed with the existing fixing device 4 or pressing block 5, etc. This method does not require the wing of the first damaged waterstop section 11, and can also achieve further fixing of the first damaged waterstop section 11, ensuring the waterstop effect of the first damaged waterstop section 11, as Figure 5 shown.

[0043] In some real-time methods, the fixing structure includes a plurality of fixing bars that span across the damaged water stop section at intervals along the length direction of the damaged water stop section. Using a plurality of fixing bars to fix at intervals along the length direction of the damaged water stop section makes the fixing operation more convenient and the fixing effect better.

[0044] Furthermore, as Figure 5 shown, the fixing bar is a steel wire 3, which has a simple structure, is easy to process, can adapt to the arc surface in the middle of the damaged water stop section, can improve the fixing effect, and is convenient for the fixing operation. The diameter of the steel wire 3 is 2 mm - 3 mm to avoid the influence of the steel wire 3 on the contact between the water stop belt and the dock gate after repair.

[0045] If the spacing of the steel wires 3 is too large, the fixing effect becomes poor, which is not conducive to the water stop effect. If the spacing of the steel wires 3 is too small, the operation is cumbersome. Furthermore, the spacing of the steel wires 3 is 300 mm - 500 mm, which makes the installation workload smaller on the premise of ensuring the fixing effect.

[0046] As Figure 5 shown, it includes fixing devices 4 and pressing blocks 5 that have been set on both sides of the damaged water stop section. The pressing block 5 is connected to the fixing device 4, and the fixing device 4 is connected to the dock pier 2. The pressing block 5 is used to press the side of the water stop belt against the dock pier 2. The steel wires 3 are arranged corresponding to the fixing devices 4 on both sides of the damaged water stop section, and the steel wires 3 are fixed to the pressing block 5 or the fixing device 4, making the fixing operation of the steel wires 3 more convenient.

[0047] Furthermore, the pressing block 5 is fixed to the corresponding side fixing device 4 through a fixing bolt 6, and the steel wire 3 is tied and fixed to the fixing bolt 6. The steel wire 3 winds around the fixing bolt 6 for 1 - 3 circles, making the fixing operation of the steel wire 3 more convenient and the fixing effect better.

[0048] Specifically, as Figure 5 and Figure 7 shown, the first damaged water stop section 11 of the water stop belt is reinforced by using the steel wire 3. The spacing of the steel wires 3 is one every 400 mm, and the steel wire 3 is tied and fixed to the fixing bolts 6 on both sides of the first damaged water stop section 11. The steel wire 3 winds around the fixing bolt 6 for 2 circles.

[0049] For the repair of the second damaged water stop section 12, the fixing structure for fixing the first damaged water stop section 11 can be adopted. At the same time, it also includes a rubber pad 7. As Figure 6 shown, the rubber pad 7 covers the outside of the arc surface in the middle of the damaged water stop section, and the fixing structure squeezes and fixes the rubber pad 7 to the outside of the arc surface in the middle of the damaged water stop section. When there is a crack 121 on the outside of the arc surface in the middle of the damaged water stop section, it greatly affects its water stop effect. By covering the rubber pad 7 on the outside of the arc surface in the middle of the damaged water stop section and squeezing and fixing it through the fixing structure, its water stop effect can be ensured.

[0050] In some embodiments, the rubber gasket 7 includes 2 to 3 pieces, and the 2 to 3 pieces of rubber gaskets 7 are stacked. The thickness of each rubber gasket 7 is 4 mm to 6 mm. If the number of stacked rubber gaskets 7 is large, the operation is cumbersome. By using 2 to 3 pieces stacked, the water stop effect is better and the workload is smaller. If the thickness of the rubber gasket 7 is too small, the water stop effect deteriorates; if the thickness of the rubber gasket 7 is too large, it is likely to affect the opening and closing of the dock gate at the dock pier 2. The thickness of each rubber gasket 7 being 4 mm to 6 mm can ensure the water stop effect on the premise of avoiding affecting the opening and closing of the dock gate at the dock pier 2.

[0051] In some embodiments, both ends of the rubber gasket 7 in the length direction exceed both ends of the damaged water stop section, and both ends of the rubber gasket 7 overlap on the outer side of the middle arc surface of the intact water stop belt. This can improve the water stop effect.

[0052] Furthermore, the overlapping length of both ends of the rubber gasket 7 and the intact water stop belt is greater than 300 mm, and the water stop effect is better.

[0053] Specifically, the arc-shaped pressing surface of the second damaged water stop section 12 of the water stop belt is damaged to form a crack 121. Two 5-mm rubber gaskets 7 are covered at the damaged part of the arc surface of the second damaged water stop section 12. The overlapping length of the rubber gasket 7 and the intact water stop section 13 is greater than 300 mm. The second damaged water stop section 12 is reinforced by using a steel wire 3. The spacing of the steel wires 3 is one every 400 mm. The steel wire 3 is tied and fixed to the fixing bolts 6 on both sides of the second damaged water stop section 12, and the steel wire 3 is wound around the fixing bolt 6 for 2 circles.

[0054] After the water stop belt is repaired by the dock gate water stop belt repair structure, no water leakage is found after the dock gate is installed, and the dock gate is in good watertight condition during the prefabrication of the immersed tube segment.

[0055] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
