[0029] Please refer to Figure 1-Figure 2 The present embodiment provides a culvert segment hoisting device 010 for hoisting a culvert segment body 100 so that the culvert segment body 100 is in the same horizontal plane as a whole, thereby solving the problem of unbalanced hoisting of the culvert segment and failure to accurately install it in place in the prior art.

[0030] Please refer to Figure 1-Figure 2The present embodiment provides a culvert section hoisting device 010, comprising a culvert section body 100, a hoisting rope 200, a first hanging member 300 and a second hanging member 400; the culvert section body 100 comprises a first side 110 and a second side 120, the length of the first side 110 is greater than the length of the second side 120, the first side 110 is provided with a first reserved hole 111 and a second reserved hole 112 arranged at intervals, and the second side 120 is provided with a third reserved hole 121, The third reserved hole 121 is relatively arranged between the first reserved hole 111 and the second reserved hole 112; the lifting rope 200 passes through the first reserved hole 111 and the second reserved hole 112; the first hanging component 300 is hung on the third reserved hole 121; the second hanging component 400 is hung on the lifting rope 200; the length of the first hanging component 300 and the second hanging component 400 is adjustable, and the length of the first hanging component 300 and / or the first hanging component 300 is adjusted to place the culvert section body 100 horizontally.

[0031] It is understandable that after the conventional lifting method is lifted by heterogeneous welding, due to the effect of gravity, the longer first side 110 part will naturally hang to the bottom, and the shorter second side 120 part will bend upward, while the correct installation position is that the longer first side 110 and the shorter second side 120 should be on the same horizontal plane, so the traditional method cannot be accurately installed.

[0032] On the special-shaped culvert section body 100, the first reserved hole 111 and the second reserved hole 112 are arranged at intervals on the longer first side 110, and the hoisting rope 200 is passed through and hung on the first reserved hole 111 and the second reserved hole 112; and the third reserved hole 121 is arranged on the shorter second side 120. When the culvert section body 100 is hoisted, the first hanging member 300 and the second hanging member 400 hoist three points at the same time, and the culvert section body 100 is placed horizontally by adjusting the first hanging member 300 and / or the length of the first hanging member 300, so that the culvert section body 100 is hoisted smoothly and accurately, which not only improves the construction speed, but also ensures the installation quality.

[0033] In this embodiment, the culvert section hoisting device 010 includes a culvert section body 100 .

[0034] In this embodiment, please refer to Figure 1-Figure 2 The culvert section body 100 is a culvert section body 100 of a round tube structure with a special-shaped end, and the culvert section body 100 is provided with a cavity 150 running through both ends; the first end of the culvert section body 100 is a plane end 130, and the second end of the culvert section body 100 is a bevel end 140. Among them, the side connecting one end of the plane end 130 and one end of the bevel end 140 is a longer first side 110, and the side connecting the other end of the plane end 130 and the other end of the bevel end 140 is a shorter second side 120.

[0035] Please refer to Figure 1 A first reserved hole 111 and a second reserved hole 112 are arranged at intervals on the first side 110 ; a third reserved hole 121 is arranged on the second side 120 , and accordingly, the third reserved hole 121 is relatively arranged between the first reserved hole 111 and the second reserved hole 112 .

[0036] The cavity 150 is connected to the first reserved hole 111 , the second reserved hole 112 and the third reserved hole 121 .

[0037] Optionally, the third reserved hole 121 is disposed at a midpoint of the second side 120 .

[0038] Optionally, the third reserved hole 121 is arranged relatively close to the first reserved hole 111 .

[0039] The manufacturing steps of the culvert segment body 100 proposed in this embodiment are as follows:

[0040] 1. Making the template of the culvert section body 100: Design the structure of the template according to the shape and size of the culvert section body 100 to ensure the geometric size and surface quality; formulate a reasonable manufacturing process in combination with the template material and structure to ensure the accuracy and service life of the template.

[0041] 2. Make the steel frame: Tie and shape the steel frame according to the drawing. The spacing and intervals must comply with the design requirements and construction acceptance specifications.

[0042] 3. Reserved lifting holes: After the steel skeleton is completed and passed the quality inspection, it is fixed on the prefabricated platform, and then the positions of the three reserved lifting holes, the first reserved hole 111, the second reserved hole 112 and the third reserved hole 121, are accurately located; reserved holes are made at these positions with PVC pipes with a specification of 50 mm, the pipes are firmly fixed with wire ties, and then denser steel bars are added around the holes for reinforcement to prevent damage to the pipe sections by the wire rope during subsequent lifting and installation.

[0043] 4. Formwork installation and debugging: Before installing the formwork, check whether the formwork surface is flat, smooth, and has no uneven deformation, and remove the slag and debris on the formwork. Install and debug the formwork to ensure its geometric dimensions and flatness; the support of the formwork should be firm and reliable, and check repeatedly after reinforcement to ensure that there is no mold running or slurry leakage during the pouring process.

[0044] When pouring concrete, it is done symmetrically on both sides of the culvert section body 100, and a small inserted vibrator is used for vibration to ensure that there is no missed vibration or over-vibration. The formwork can be removed only when the strength required by the design is reached. The outer formwork is removed first, and then the inner formwork is removed, and the concrete must not be damaged. The formwork can only be removed and transported after it is separated from the concrete. During the concrete curing period, it is covered with plastic film and moisturized by sprinkling water.

[0045] In this embodiment, please refer to Figure 2 The culvert section lifting device 010 includes a lifting rope 200 , and the lifting rope 200 passes through the first reserved hole 111 and the second reserved hole 112 .

[0046] It is understandable that the use of the lifting rope 200 to connect the first reserved hole 111 and the second reserved hole 112 makes it more convenient to adjust the length and position of the first hanging component 300.

[0047] The lifting rope 200 may be a steel wire rope.

[0048] In this embodiment, please refer to Figure 2 The culvert section hoisting device 010 includes a first hanging component 300; the first hanging component 300 is hung on the third reserved hole 121, and the length of the first hanging component 300 is adjustable.

[0049] Optionally, the first hanging component 300 includes a first hook and a first sling connected to each other, the length of the first sling is adjustable, and the first hook is hung with the sling rope 200 .

[0050] In this embodiment, please refer to Figure 2 The culvert section hoisting device 010 includes a second hanging component 400; the second hanging component 400 is hung with the hoisting rope 200, and the length of the second hanging component 400 is adjustable.

[0051] Optionally, the second hanging component 400 includes a second hook and a second sling connected to each other, the length of the second sling is adjustable, and the second hook is hung on the third reserved hole 121 .

[0052] In this embodiment, please refer to Figure 2 The culvert section hoisting device 010 includes a hoisting device 500 , which is connected to the first hanging member 300 and the second hanging member 400 and is used to adjust the length of the first hanging member 300 and the second hanging member 400 .

[0053] Optionally, the lifting device 500 is used to adjust the length of the first sling and the second sling.

[0054] Wherein, the lifting device 500 is a crane, and the first hanging component 300 and the second hanging component 400 can be a sling and a hook provided by the lifting device 500 itself.

[0055] Please refer to Figure 1-Figure 3 The working principle of the culvert section hoisting device 010 of this embodiment is:

[0056] 1. Preparation for hoisting: Arrange the driving channel and working platform of the hoisting equipment 500 to ensure that the hoisting equipment 500 can be smoothly set up after entering the site. The equipment manager should be notified when the hoisting equipment 500 enters the site. Before hoisting, the working environment, hoisting equipment, wire rope, etc. of the hoisting equipment 500 should be checked. The hoisting operation can only be carried out after meeting the requirements. The sandbags 700 used to temporarily fix the culvert section body 100 should be checked for quantity and appearance quality to ensure that there is no sand leakage.

[0057] 2. Before lifting: locate the center line on the bottom surface of the culvert concrete foundation 600, and use red paint to mark the upper and lower center line positions on the top and bottom surfaces of the culvert section body 100 respectively. After marking, check again with an instrument to ensure the accuracy of the position.

[0058] Among them, the connection of the lifting rope 200 must be firm. Pass the first hanging part 300 through the lifting rope, pass the second hanging part 400 through the third reserved hole 121 and fix it firmly to the culvert section body 100. First, conduct a trial lifting experiment to ensure that the used parts are coordinated and safe; review the changes in various parts, etc. After the culvert section body 100 is lifted and turned, its bottom should be more than 0.5 meters higher than all obstacles.

[0059] 3. Formal hoisting: Pass the first hook of the first hanging member 300 through the hoisting rope to connect and fix, pass the second hook of the second hanging member 400 through the third reserved hole 121 to connect and fix, and slowly lift and move the three points at the same time. When the culvert section body 100 is located at a height of 0.5 meters above the culvert concrete foundation 600, the first positioning of the culvert section body 100 is performed: first adjust the left and right directions of the culvert section body 100 so that the center line of the culvert section body 100 and the center line of the foundation are roughly on the same vertical line, then fix the height of the first reserved hole 111 and the second reserved hole 112, slowly adjust the height of the third reserved hole 121, and use the level to measure the elevation to ensure that the first reserved hole 111, the second reserved hole 112 and the third reserved hole 121 are on the same horizontal plane.

[0060] After the first positioning of the culvert section body 100 is completed, the lengths of the first sling and the second sling are adjusted synchronously so that the three lifting points are slowly lowered at the same time. When the culvert section body 100 is 5-10 cm away from the surface of the culvert concrete foundation 600, the culvert section body 100 is positioned for the second time, and the first adjustment steps are repeated until the culvert section body 100 falls and is in place according to the designed position.

[0061] Please refer to Figure 3After the culvert section body 100 is hoisted into place, the prepared sandbags 700 and wooden wedges are used to temporarily fix the culvert section body 100. A fixing point is set every 50 cm. After the temporary fixing work is completed and the culvert section body 100 is stable, the template is installed in the remaining unfixed parts and the base concrete is poured. The base uses dry hard concrete with a small slump. As the base concrete is poured, the sandbags and wooden wedges are gradually removed. During the removal of temporary fixings, the stability of the culvert section body 100 must be ensured to ensure that it does not move. If an abnormal situation occurs, the removal must be stopped immediately and the operation can be continued only after it is stable.

[0062] 4. Blocking the reserved holes: After the installation of the culvert section body 100 is completed, the first reserved hole 111, the second reserved hole 112 and the third reserved hole 121 are blocked with high-strength mortar, and then waterproof rolls are pasted on the parts to ensure that there is no water leakage or seepage. After the blocking work is completed, the external waterproofing construction of the entire culvert is carried out.

[0063] Among them, the utility model has many advantages. First, because the culvert section body 100 is a prefabricated installation process, the culvert section body 100 is made in advance in the prefabrication site and hoisted on site, which greatly reduces the workload on the construction site and improves the construction efficiency. If the traditional method is used, the culvert section body 100 can only adopt the cast-in-place process, especially the round pipe culvert section body 100, the cast-in-place process is relatively complicated, and the quality is difficult to control. Second, the quality of the culvert section body 100 is easier to control, thereby improving the quality of the project. Due to the reduction in on-site workload, the influence of uncertain factors on the construction site on the quality of the project is avoided, and the quality of the project is further improved. Third, the hoisting of the culvert section body 100 can be prepared and produced in advance, which shortens the construction period compared to on-site casting. The on-site workload is reduced, the engineering task can be completed faster, and the construction period is further shortened. Therefore, the utility model can accurately install the pipe section in one go through this method, saving time, improving efficiency, and ensuring installation quality.

[0064] In summary, the culvert section lifting device 010 proposed in the utility model, by setting the first reserved hole 111, the second reserved hole 112 and the third reserved hole 121 on the culvert section body 100, and using the three-point lifting method, when the culvert section body 100 is lifted, the first hanging member 300 and the second hanging member 400 lift three points at the same time, and by adjusting the first hanging member 300 and / or the length of the first hanging member 300, the culvert section body 100 is placed horizontally, so that the culvert section body 100 is smoothly lifted into place, thereby ensuring that the culvert section body 100 is in the designed position and accurately positioned during the lifting process, which not only improves the construction speed but also ensures the installation quality.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
