Description

Technical Field

[0001] The invention relates to the technical field of deep foundation pit excavation, and in particular to a safe and quick electric drainage pipeline suspension bracket and a use method thereof. Background Art

[0002] The power pipeline is a kind of construction method that meets the requirements of the cable access channel of the substation and the undergrounding of the overhead line, and provides a power channel for the power supply of the plots along the line. The suspension protection of the power pipeline is a construction method to solve the difficulties in pipeline relocation and to ensure the total construction period requirements and safe and reliable construction. If the traditional relocation method is followed, it will have a great impact on the surrounding environment, which is not conducive to urban traffic. At the same time, the construction process is numerous, which increases project investment, construction period and risk.

[0003] At present, there are many existing pipeline suspension protection methods, with uneven quality and low standardization. They are subject to great limitations when used and are not very practical. In addition, the structures of most equipment are complex, and users need to spend a lot of time to change and cut the pipelines during construction, which reduces the work efficiency of workers and is not very practical. In addition, the production cost of most equipment is high, and once a failure occurs, a large amount of money will be required for maintenance, which has low economic benefits and is not very practical.

[0004] This is particularly evident during the construction of underground stations in urban rail transit. The relocation of the drainage pipelines has a great impact on the surrounding environment, a long relocation cycle, high costs, and many safety risks, which need to be resolved. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the shortcomings of the prior art, the present invention provides a safe and quick electric drainage pipeline suspension bracket and a method of use, which solves the problems of great impact on the surrounding environment caused by the relocation of electric drainage pipelines in the construction of urban rail transit underground stations, long relocation period, high cost and many safety risks.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a safe and quick electric drainage pipe suspension bracket, including a bracket body, wherein two bracket bodies are provided, and a support beam channel steel is installed between the two bracket bodies, a protective sleeve is installed above the support beam channel steel, a horizontal channel steel scissors brace is installed on the upper outer wall of the hanger body, and a warning light strip is installed on the hanger body, and the warning light strip is electrically connected to an external power supply through a power cord.

[0009] Preferably, the hanger body is composed of a first I-beam and a second I-beam, the length of the first I-beam is greater than the length of the second I-beam, and the first I-beam and the second I-beam are fixed by welding with a welding gun.

[0010] Preferably, dense joist channel steels are arranged on the hanger body, and each adjacent two joist channel steels are arranged at equal intervals.

[0011] Preferably, the width of the horizontal channel steel scissors brace is greater than the width of the supporting beam channel steel.

[0012] A method for using a safe and quick electric drainage pipeline suspension bracket comprises the following steps:

[0013] ① Pretreatment of the construction environment: The concrete encapsulating the power supply pipeline is carefully chiseled out with a handheld pneumatic pick, and the cable casing is retained. The casing joints are tied with steel wire to prevent damage to the cable due to casing deformation. The station crown beam is set below the power pipeline to ensure that the crown beam in the power area passes continuously. After the construction is completed, the crown beam serves as the fulcrum of the power pipeline and the suspension steel, and the part crossing the foundation pit is suspended with steel;

[0014] ② Installation of the hanger body: The hanger body is made of I-beams, fixed on both sides of the protective casing. The I-beams are spliced ​​on the ground and are available in two lengths: 12m and 9m. The joints of the two I-beams are welded, and the welds are reinforced with steel plates. The earthwork on both sides and above the protective casing is excavated manually. After completion, the I-beams are hoisted as a whole above the crown beam and connected to the embedded steel plate on the top of the crown beam;

[0015] ③ Installation of joist channel steel: 10# channel steel is laid at intervals of 1 meter at the bottom of the hanger body as joist channel steel, and the joist channel steel is fully welded to the hanger body;

[0016] ④ Installation of horizontal channel steel scissors brace: The horizontal channel steel scissors brace is welded on the top of the hanger body;

[0017] ⑤ Dismantling of the suspension frame and restoration of the pipeline: The bottom of the protective casing is backfilled densely. When there is insufficient space for the tamping machine, sand is backfilled to 20 cm from the bottom of the casing, and then the casing is encapsulated with concrete. Before dismantling the suspension frame steel system, the pier concrete is poured in sections to prevent the protective casing from sinking. Then the horizontal channel steel scissors brace, the hanger body, and the support beam channel steel are dismantled in sections and in sequence.

[0018] Furthermore, a safety sign reflective sticker is affixed to the outer wall of the hanger body.

[0019] Furthermore, the horizontal channel steel scissors struts are laid continuously, and the span of each horizontal channel steel scissors strut is less than 5 meters.

[0020] (III) Beneficial effects

[0021] The present invention provides a safe and quick electric drainage pipeline suspension bracket and a method of use. It has the following beneficial effects:

[0022] (1) The present invention has a simple structure and a safe and controllable construction site. The main body of the suspended steel section is determined through mechanical calculation and is arranged on both sides of the electric drainage pipe. A support beam and channel steel are welded at the bottom of the steel section to bear the uniformly distributed load of the electric drainage pipe. A scissor brace is arranged on the top for stability. Since the pipeline is protected by steel sections all around, it is safer and more reliable than the relocation and traditional suspension protection with complicated procedures. It has fewer construction procedures and will not cause a significant impact on urban traffic. It is highly practical.

[0023] (2) The standard requirements of the present invention are high. Warning light strips and safety signs are used around the main body of the suspended steel. At the same time, the supporting points on both sides are reliably connected to the crown beam. Wood plywood is laid at the bottom of the cable casing and the top is covered with a dense net. It is neat and tidy, and the on-site safe and civilized construction is standardized. Compared with the direct ordinary suspension method, it is more in line with the construction standardization requirements and has few limitations when used.

[0024] (3) The manufacturing cost of the present invention is low. The suspension body adopts steel suspension, which is a turnover material and can be reused. Even if a failure occurs, there is no need to spend a lot of money on repair. At the same time, the steel suspension does not damage the original pipeline. Compared with the pipeline relocation, it saves the cost of new cables, power outage losses, pipe trough construction, etc., and its economic benefits are high, and the suspension protection measures do not change.

[0025] The original pipeline status reduced the time for relocation and cutting, and the subsequent restoration was treated with encapsulated concrete, which greatly saved time and improved work efficiency compared to pipeline relocation and subsequent restoration.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The embodiment of the present invention provides a safe and quick electric discharge pipeline suspension bracket and a method of using the same. Figure 1-3 As shown, it includes a hanger body 1, and there are two hanger bodies 1 in total, and a support beam channel steel 2 is installed between the two hanger bodies 1, a protective sleeve 3 is installed above the support beam channel steel 2, a horizontal channel steel scissors brace 4 is installed on the upper outer wall of the hanger body 1, and a warning light strip 5 is installed on the hanger body 1, and the warning light strip 5 is electrically connected to an external power supply through a power cord.

[0032] In the present invention, the hanger body 1 is composed of a first I-beam and a second I-beam, the length of the first I-beam is greater than the length of the second I-beam, and the first I-beam and the second I-beam are fixed by welding with a welding gun, so that the user can choose a suitable I-beam according to actual conditions when using the equipment. If the pipeline is long, the first I-beam and the second I-beam can be welded to make the length of the hanger body 1 sufficient, and then the weld between the two I-beams can be strengthened with a steel plate to make the strength of the hanger body 1 sufficient. If the pipeline is short, you can choose one between the first I-beam and the second I-beam. Since the length of the first I-beam is larger, the equipment can meet different construction conditions and has strong practicality.

[0033] In the present invention, dense joist channel steels 2 are arranged on the hanger body 1, and each adjacent joist channel steels 2 are arranged at equal intervals. This is so that the user can weld the dense joist channel steels 2 at equal intervals on the hanger body 1 when installing the equipment, so that the protective sleeve 3 will not collapse the joist channel steels 2 and cause them to slide during installation. At the same time, the joist channel steels 2 with equal intervals can also increase the stability of the equipment after installation, so that the equipment will not shake at will.

[0034] In the present invention, the width value of the horizontal channel steel scissors strut 4 is greater than the width value of the supporting beam channel steel 2 so that the horizontal channel steel scissors strut 4 can be welded to the upper outer wall of the hanger body 1 by a welding gun, so that the position of the protective sleeve 3 is limited by the horizontal channel steel scissors strut 4 and will not slide out at will, which has strong practicality. The larger width value of the horizontal channel steel scissors strut 4 is to enable the horizontal channel steel scissors strut 4 to be installed normally. Once the width value of the horizontal channel steel scissors strut 4 is smaller, the horizontal channel steel scissors strut 4 cannot be placed on the upper outer wall of the hanger body 1, so that the normal use of the equipment is affected.

[0035] In the present invention, a method for using a safe and quick electric drainage pipeline suspension frame includes the following steps: ① Pretreatment of the construction environment: The power supply pipeline encapsulation concrete is carefully chiseled out with a handheld pneumatic pick, the cable casing is retained, and the casing joints are bound with steel wires to prevent damage to the cable due to casing deformation. The station crown beam is set below the electric drainage pipeline to ensure that the crown beam in the electric drainage area passes continuously. After the construction is completed, the crown beam serves as the fulcrum of the electric drainage pipeline and the suspension steel, and the part crossing the foundation pit is suspended by steel;

[0036] ② Installation of the hanger body 1: The hanger body 1 is made of I-beams, fixed on both sides of the protective casing 3. The I-beams are spliced ​​on the ground and are available in two lengths of 12m and 9m. The joints of the two sections of I-beams are welded, and the welds are reinforced with steel plates. The earthwork on both sides and above the protective casing 3 is excavated manually. After completion, the I-beams are hoisted as a whole above the crown beam and connected to the embedded steel plate on the top of the crown beam;

[0037] ③ Installation of joist channel steel 2: 10# channel steel is laid at intervals of 1 meter at the bottom of the hanger body 1 as joist channel steel 2, and the joist channel steel 2 is fully welded to the hanger body 1;

[0038] ④ Installation of horizontal channel steel scissors brace 4: The horizontal channel steel scissors brace 4 is welded to the top of the hanger body 1;

[0039] ⑤ Dismantling of the suspension frame and restoration of the pipeline: The bottom of the protective casing 3 is backfilled densely. When there is insufficient space for the tamping machine, sand is backfilled to 20 cm from the bottom of the casing, and then the casing is encapsulated with concrete. Before dismantling the suspension frame steel system, the pier concrete is poured in sections to prevent the protective casing 3 from sinking. Then, the horizontal channel steel scissors support 4, the hanger body 1, and the support beam channel steel 2 are dismantled in sections and in sequence.

[0040] In the present invention, the outer wall of the hanger body 1 is affixed with a safety sign reflective sticker to effectively avoid mechanical collision during construction.

[0041] In the present invention, the horizontal channel steel scissors struts 4 are laid continuously, and the span of each horizontal channel steel scissors strut 4 is less than 5 meters. The horizontal channel steel scissors struts 4 are made of 10# channel steel, which effectively prevents the lateral deformation of the overall steel system.

[0042] Working principle: When the hanger of the present invention is used, the user first selects a suitable hanger body 1 according to the actual situation. If the pipeline is long, the first I-beam and the second I-beam can be welded to make the hanger body 1 long enough, and then the weld between the two I-beams can be strengthened with a steel plate to make the hanger body 1 strong enough. If the pipeline is short, the user can choose between the first I-beam and the second I-beam. Since the length of the first I-beam is large, the equipment can meet different construction conditions and has strong practicality. After the hanger body 1 is installed, , and then use manual excavation on both sides of the pipeline and above the earth. After completion, the I-beam is hoisted as a whole to the top of the crown beam and reliably connected to the embedded steel plate on the top of the crown beam. Then, the support beam channel steel 2 is welded at the bottom of the hanger body 1. During installation, a channel steel is laid at every 1m interval as the support beam channel steel 2, and the channel steel and the I-beam are fully welded. After that, the protective casing 3 is installed. During installation, wood plywood is laid at the bottom of the casing and the top is covered with a dense mesh. Then, the horizontal channel steel scissors support 4 is installed on the hanger body 1, so that an electric drainage pipeline suspension frame can be obtained.

[0043] To sum up, when the present invention is used at night, the warning light strip 5 can be electrically connected to the external power supply through the power cord, so as to emit a warning light, making the warning of the equipment higher. The equipment improves the construction efficiency. The suspension protection measures do not change the original pipeline state, reduce the relocation and splicing time, and the subsequent restoration adopts encapsulated concrete treatment. Compared with the pipeline relocation and subsequent restoration, it greatly saves time and improves efficiency, and its practicality is strong.
