Description

Technical Field

[0001] The invention belongs to the technical field of breach plugging, and in particular relates to a split-type working platform and an operating method for breach plugging operations. Background Art

[0002] At present, the foundations of most river embankments in China have been damaged to a certain extent due to long-term scouring and infiltration. When the flood season comes every year, the embankments often collapse.

[0003] At present, the main blocking methods include earth-rock blocking technology, gabion blocking technology and steel-wood-earth-rock combination dam blocking technology. Among them, the earth-rock blocking technology and gabion blocking technology mainly use bundled brooms and thrown willow pillow stones to block the mouth, which takes a relatively long time. In addition, the underwater stability coefficient of the material at the breach is only 0.7-0.8. Many thrown objects are often dispersed in the rapids due to their poor stability. Generally, the material actually used for blocking is 1.2-1.5 times the calculated amount, and some are as high as more than 2 times. The blocking materials and costs are huge.

[0004] The most commonly used and effective plugging technology is the steel-wood earth-rock composite dam plugging technology. The basic structure of the composite dam using this technology consists of four parts: steel-wood frame, filling material, upstream and downstream slope protection and anti-seepage body. Its working principle is to drive steel pipes or wooden piles into the rapids, use horizontal and diagonal braces to form a steel-wood frame, gather bagged gravel and build slope protection with earth and stone, thus forming a water retaining dam to achieve the purpose of plugging.

[0005] However, in the process of implementing the plugging, construction is usually carried out step by step from both sides of the dam breach to the middle, which will result in a long plugging operation time and high labor intensity, especially for large breaches, and cannot meet the requirements of rapid plugging.

[0006] In addition, the steel-wood-earth-rock composite dam needs to be piled and connected in moving water during the plugging process, which is somewhat difficult. When the flow rate is high, manual piling is impossible and can only be assisted by engineering machinery, and the water piling engineering machinery must be carried on a large platform foundation for operation.

[0007] In this context, it is necessary to study a method for rapid sealing of dam breaches in order to effectively reduce the breach flow rate and create conditions for subsequent safe and efficient completion of breach sealing operations. Summary of the invention

[0047] And according to the operation requirements, a gap plate 12 is arranged between the straightening box 11 of the bridge span 1 and the standard box 6 of the bridge span 1.

[0048] Eight guide plates 13 are arranged on the sides of both ends of the bridge span 1.

[0049] like Figure 5 As shown, the straightening tray 4 is composed of a first tray 16, a flat roller 18, an inclined roller 17, a first guide pulley 15, and a hydraulic traction winch 14. The first tray 16 is provided with single-ear and double-ear waist round hole plates at four corners.

[0050] It can be installed in the middle of the deck of the pile-driving ship 4 by means of a truck crane. The main function of the straightening tray 4 is to cooperate with the straightening function of the bridge span 1 to complete the straightening operation of the entire bridge span 1. The flat roller 18 is used for supporting and moving the bridge span 1 on the deck surface, and the inclined roller 17 is used for limiting and guiding the bridge span 1 on the straightening tray 4; the hydraulic traction winch 14 is connected to the middle of the bridge span 1 through a steel wire rope, and is used for the connection and displacement adjustment between the bridge span 1 and the pile-driving ship assembly 2.

[0051] like Figure 6As shown, the mooring pallet 5 is composed of a second pallet 19, a second guide pulley 20, an anchor frame 21, a plough anchor 22 and the like.

[0052] The anchoring tray 5 is connected to the ground anchor on the deck of the piling vessel 4 by bolts.

[0053] The anchoring tray 5 is mainly used for anchoring operations to achieve the anchoring of the entire working platform.

[0054] According to a second aspect of the present invention, there is provided an operating method of a split working platform for breach plugging operations, comprising the split working platform for breach plugging operations of any one of the first aspect of the present invention, comprising: assembling a pile-driving ship assembly 2 and assembling a bridge span 1, installing the bridge span 1 on a pile-driving ship assembly 4 to form a split working platform, and transporting the split working platform to the breach for plugging operations.

[0055] Specific:

[0056] Step 1: Figure 7 As shown, 12 guide boxes 7, 16 standard boxes 6, 8 power boxes 8 and a power system 9 are transported to the work site, and workers assemble them into 4 piling boats 4 on the water using a truck crane.

[0057] Step 2: The straightening pallet 4 and the anchoring pallet 5 are hoisted to the piling vessel 4 by a truck crane, and assembled into a piling vessel assembly 2.

[0058] Step 3: If Figure 8 As shown, the standard box 6 and the extension box 11 are hoisted into the water by a truck crane, and the operators assemble them into a bridge span 1.

[0059] Step 4: Fig. 9 As shown, the hydraulic straightening mechanism inside the straightening box 11 of the operating bridge span 1 is used to lift the standard boxes 6 at both ends to a certain angle.

[0060] Step 5: Operate the straightening mechanism inside the bridge span 1 to lift the standard boxes 6 at both ends to a certain angle.

[0061] Step 6: Fig.10 As shown, the piling ship assembly 2 sails to both ends of the span 1, and aligns the span 1 with the straightening tray 4 on the piling ship assembly 2. The operator operates the hydraulic traction winch 14 on the straightening tray 4, connects the wire rope on the winch to the connecting ear in the middle of the span 1, and tightens the wire rope. The operator operates the straightening mechanism of the span 1. Under the action of the straightening mechanism and the wire rope, the span 1 is erected on the piling ship assembly 2 and flattened. After the span 1 is stable, the hydraulic traction winch 14 is operated, and the span 1 is placed at a suitable position of the piling ship assembly 2 through the traction of the wire rope and the action of the flat roller 18 and the inclined roller 17 of the straightening tray 4, forming a 30m span split work platform.

[0062] Step 7: Repeat step 6 to form two split-type working platforms with a span of 30m in total.

[0063] Step 8: Fig.11 As shown, the operator operates the piling barge assembly 2 to align and connect two split platforms with a span of 30m. Then, the two middle piling barge assemblies 2 are towed to the two ends by the hydraulic traction winch 14 and connected with the piling barge assemblies 2 at the two ends to form a split working platform with a span of 50m.

[0064] Step 9: Fig.12 As shown, the 50m span split work platform is sailed to about 100m upstream of the breach, and the plow anchor 22 on the pile-driving ship assembly 2 in the platform is dropped. At the same time, a group of piles is driven by steel pipe piles and pile drivers on the same side of the breach, about 25 meters away from the breach, as a fastening point. The piles can be fastened twice by using the traction wire of the truck group transporting the plugging material to ensure a certain safety margin. The truck group is set on the embankment, about 25 meters away from the breach.

[0065] Step 10: Fig.12 As shown, two sets of steel wire ropes are fastened to the plow anchor 22 and the pile group, wherein one end of the two sets of steel wire ropes of the plow anchor 22 can be temporarily set on the gate bridge. The platform sails back to the side of the embankment, at which time the free end of the first set of steel wire ropes of the plow anchor 22 is connected to the hydraulic traction winch 14 at the bow end of the pile driving ship 4 on the right side of the gate bridge, and the free end of the first set of steel wire ropes of the pile group is connected to the hydraulic traction winch 14 at the tail end of the pile driving ship 4 on the left side.

[0066] Step 11: Figure 13-Figure 14 As shown, the work platform is started to rotate and sail with the pile group as the rotation hinge. At the same time, the operators operate the winches on the left and right sides to ensure that the first set of wire ropes are in the traction state.

[0067] Step 12: Figure 14-15 As shown, when the working platform rotates to be perpendicular to the embankment, the free end of the second set of steel wire ropes of the plow anchor 22 is connected to the hydraulic traction winch 14 at the rear end of the piling ship 4 on the right side of the gate bridge, and the free end of the steel wire ropes of the pile group is connected to the hydraulic traction winch 14 at the bow end of the piling ship 4 on the left side. After the steel wire ropes are tightened, all the first set of steel wire ropes are loosened.

[0068] Step 13: Figure 16-Figure 17 As shown, the operation is assisted by the traction of the steel wire rope of the plow anchor 22 and the pile group, and the plow continues to rotate and sail toward the left bank until it rests on the bank.

[0069] Step 14: After the working platform is against the embankment, the pile legs of the anchoring system 10 of the pile-driving ship assembly 2 in the platform are driven into the water, and the steel wire rope of the plow anchor 22 is tightened to complete the anchoring. At this point, the entire working platform for breach plugging is set up and, with the assistance of the steel wire rope traction of the plow anchor 22 and the pile group, it continues to rotate and sail toward the left embankment until it is against the embankment.

[0070] In summary, it can be seen from the above scheme that the embodiment of the present invention provides a split working platform and working method for breach plugging operations, which has the following beneficial effects: effectively reducing the breach flow rate, creating conditions for the subsequent safe and efficient completion of the breach plugging operation.

[0071] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
