Description

Technical Field

[0001] This utility model relates to the field of municipal engineering excavation and pipe laying construction technology, and in particular to a parallel pipe protection device. Background Technology

[0002] During the excavation and construction of new pipelines, especially in older urban areas, issues such as old and new pipelines sharing the same trench or running parallel to each other are common. If existing, long-standing pipelines are buried shallowly alongside the new ones, they are highly susceptible to damage if necessary protective measures are not taken. For example, a common DN600 concrete flat-joint rainwater pipe, over 30 years old and in disrepair, is considered a high-risk pipeline network. Special attention must be paid to its surrounding area during new pipeline construction, and targeted protective measures must be implemented to prevent damage and ensure construction progress and safety.

[0003] Existing pipeline protection devices do not include measures to protect existing pipelines that are parallel to the new pipeline, making protection more difficult when the existing pipeline is in a different location. Utility Model Content

[0004] This utility model provides a parallel pipeline protection device that effectively protects the original pipeline that is parallel to the newly built pipeline.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a parallel pipeline protection device, including a trench formed by excavating a new pipeline. The new pipeline is located at the bottom of the trench, and an existing pipeline parallel to the new pipeline is located above it. An I-beam is installed at the top of the trench, and the two ends of the I-beam are respectively located on the two side walls of the trench. A monorail trolley is installed on the lower flange of the I-beam, and the monorail trolley can reciprocate along the length direction of the lower flange of the I-beam. The monorail trolley is equipped with a locking device, and a sling for lifting the existing pipeline is installed at the lower end of the monorail trolley.

[0007] Furthermore, a U-shaped protective plate that mates with the original pipe is provided between the sling and the original pipe.

[0008] Furthermore, the U-shaped protective plate is a U-shaped carbon fiber plate, and a U-shaped rubber structural layer is provided on the inner side of the U-shaped carbon fiber plate.

[0009] Furthermore, a first support and a second support are respectively provided on the top of the two side walls of the trench, the first support and the second support are arranged opposite to each other, and the two ends of the I-beam are respectively set on the first support and the second support.

[0010] Furthermore, the multiple I-beams are evenly spaced along the length of the original pipeline.

[0011] Furthermore, the spacing between two adjacent I-beams is 3m.

[0012] Furthermore, the monorail trolley includes a mounting rod with opposing mounting plates. The lower end of each mounting plate has a through hole that mates with the mounting rod. The two mounting plates are slidably fitted onto the ends of the mounting rod through the corresponding through holes. Two axles are horizontally spaced at the upper end of each mounting plate, with the axles facing each other. A single-sided track wheel is fitted onto each axle. A retaining spring groove is circumferentially located at the free end of each axle, and a retaining spring is engaged within the groove. The lower flange of the I-beam is sandwiched between the two mounting plates. The small wheel of the single-sided track wheel is in contact with the corresponding lower flange of the I-beam, and the large wheel is located on the side of the corresponding lower flange of the I-beam. The mounting rod is a double-ended bolt with external threads on both sides. Nuts are threaded onto both ends of the double-ended bolt, and the nuts are located on the outer side of the mounting plate.

[0013] The beneficial effects of this utility model are:

[0014] This application discloses a parallel pipeline protection device. A trench is excavated for the construction of a new pipeline. The new pipeline and the existing pipeline are parallel to each other within the excavated trench. The new pipeline is laid at the bottom of the trench, and the existing pipeline is above it. An I-beam is placed horizontally at the top of the trench. A monorail trolley is mounted on the lower flange of the I-beam and moves back and forth along the length of the lower flange. The monorail trolley is equipped with a locking device, and a sling is attached to the lower end of the monorail trolley to lift the existing pipeline. During trench excavation and new pipeline construction, the monorail trolley is moved along the lower flange of the I-beam to directly above the existing pipeline. The locking device then locks the monorail trolley. This device adapts to various positions of the existing pipeline within the trench. The sling is then attached to the existing pipeline to lift it. This device effectively protects the existing pipeline parallel to the new pipeline, preventing damage and ensuring construction safety while improving efficiency. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a parallel pipeline protection device, comprising a trench 1 formed by excavating a new pipeline, a new pipeline 2 at the bottom of the trench 1, an existing pipeline 3 parallel to the new pipeline 2 above the new pipeline 2, an I-beam beam 5 at the top of the trench 1, the two ends of the I-beam beam 5 respectively set on the two side walls of the trench 1, a monorail trolley 6 set on the lower flange plate of the I-beam beam 5, the monorail trolley 6 can reciprocate along the length direction of the lower flange plate of the I-beam beam 5, the monorail trolley 6 is equipped with a locking device, and a sling 7 for lifting the existing pipeline 3 is set at the lower end of the monorail trolley 6. The soil surface at the top edge of both sides of the trench 1 is leveled so that the I-beam beam 5 is placed horizontally on the trench 1. The two ends of the I-beam beam 5 extend 1m beyond the top edge of both sides of the trench 1, so that the I-beam beam 5 is placed horizontally on the trench 1 with stability. The lower flange plates at both ends of the I-beam beam 5 are in contact with the top edge of both sides of the leveled trench 1.

[0024] A parallel pipeline protection device based on the above structure is constructed by excavating a trench 1 for the construction of a new pipeline 2. The new pipeline 2 and the original pipeline 3 are located parallel to each other within the trench 1. The new pipeline 2 is laid at the bottom of the trench 1, and the original pipeline 3 is located above the new pipeline 2. An I-beam 5 is placed horizontally at the top of the trench 1. A monorail trolley 6 is installed on the lower flange of the I-beam 5, which reciprocates along the length of the lower flange of the I-beam 5. The monorail trolley 6 is equipped with a locking device, and a locking device is installed at the lower end of the monorail trolley 6. The sling 7, which lifts the original pipeline 3, is used during trench excavation and new pipeline construction. The monorail trolley 6 is moved along the lower flange of the I-beam 5 to directly above the original pipeline 3. The locking device locks the monorail trolley 6. This method is suitable for various positions of the original pipeline 3 within the trench 1. The sling 7 is then attached to the original pipeline 3 to lift it. This effectively protects the original pipeline 3, which is parallel to the new pipeline 2, and prevents damage to the original pipeline 3. This effectively ensures construction safety and improves construction efficiency.

[0025] As one implementation method, such as Figure 1 , Figure 2 As shown, a U-shaped protective plate that mates with the original pipe 3 is provided between the sling 7 and the original pipe 3.

[0026] The U-shaped protective plate protects the original pipe 3. The U-shaped protective plate covers the bottom wall of the original pipe 3, and the sling 7 is tied to the U-shaped protective plate.

[0027] As one implementation method, such as Figure 1 , Figure 2 As shown, the U-shaped protective plate is a U-shaped carbon fiber plate, and a U-shaped rubber structural layer is provided on the inner side of the U-shaped carbon fiber plate.

[0028] The U-shaped carbon fiber plate is lightweight and high-strength, meeting the requirements for both lightweighting and structural strength. The U-shaped rubber structural layer provides flexible protection for the outer wall of the original pipe 3, enhancing its protective effect.

[0029] As one implementation method, such as Figure 1 , Figure 2 As shown, the top of the two side walls of the trench 1 are respectively provided with a first support 4 and a second support 4, which are arranged opposite to each other. The two ends of the I-beam beam 5 are respectively set on the first support 4 and the second support 4.

[0030] The first support 4 and the second support 4 can be made of cement and placed on the top of the two side walls of the leveled trench 1 respectively. The first support 4 and the second support 4 are flush with each other. The two ends of the I-beam beam 5 are placed on the first support 4 and the second support 4 to stably support the I-beam beam 5.

[0031] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 As shown, multiple I-beams 5 are evenly spaced along the length extension direction of the original pipeline 3.

[0032] The spacing between two adjacent I-beams 5 is 2m-5m. The spacing can be adjusted appropriately according to the material, diameter and medium of the original pipe 3 to be protected. The more easily the original pipe 3 is damaged, the larger the diameter and the higher the density of the medium in the pipe, the smaller the spacing between two adjacent I-beams 5.

[0033] In one implementation, the spacing between two adjacent I-beams 5 is 3m.

[0034] An I-beam beam 5 is placed every 3 meters to better protect the original pipe 3 while reducing the use of I-beam beams 5.

[0035] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 As shown, the monorail trolley 6 includes a mounting rod 601, with opposing mounting plates 602 on the mounting rod 601. The lower end of each mounting plate 602 has a through hole that mates with the mounting rod 601. The two mounting plates 602 are slidably fitted onto the two ends of the mounting rod 601 through the corresponding through holes. Two axles 603 are laterally spaced at the upper end of each mounting plate 602, with the axles 603 facing each other. A single-sided track wheel 604 is fitted onto each axle 603, and a circumferentially arranged... A retaining ring groove is provided, in which a retaining ring is engaged. The lower flange of the I-beam beam 5 is sandwiched between two mounting plates 602. The small wheel of the single-sided track wheel 604 is in contact with the corresponding lower flange of the I-beam beam 5, and the large wheel of the single-sided track wheel 604 is located on the side of the corresponding lower flange of the I-beam beam 5. The mounting rod 601 is a double-ended bolt, and both ends of the mounting rod 601 are provided with external threads. The two ends of the double-ended bolt are threaded to nuts 605, and the nuts 605 are located on the outside of the mounting plate 602.

[0036] The monorail trolley 6 is moved along the lower flange of the I-beam beam 5 to directly above the original pipe 3. Nut 605 is tightened, causing the mounting plate 602 to move towards the lower flange of the I-beam beam 5, which in turn moves the single-sided track wheel 604 towards the lower flange of the I-beam beam 5 until the large wheel of the single-sided track wheel 604 abuts against the lower flange of the I-beam beam 5, locking the monorail trolley 6 in place. This process, involving moving the monorail trolley 6 along the lower flange of the I-beam beam 5 to directly above the original pipe 3 and tightening nut 605, locks the monorail trolley 6 in place. This method adapts to various situations where the original pipe 3 to be protected is located within the trench 1.

[0037] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
