Description

Technical Field

[0001] The utility model relates to the technical field of pipeline trench construction, in particular to a temporary pipeline trench supporting structure. Background Art

[0002] With economic progress and urban development, the amount of projects such as new construction, reconstruction, and maintenance of municipal pipelines such as rainwater and sewage pipes, heat pipes, and gas pipelines is increasing day by day. Common laying methods for underground municipal pipelines include excavation laying and pipe jacking. Among them, excavation laying is the most common laying method in domestic municipal pipeline construction projects because of its safety, economy, and few restrictions. The depth of municipal pipeline trench excavation is generally 1.5 meters to 3 meters. Within this range, vertical excavation is a common excavation method. However, vertical excavation inevitably requires construction workers to go down to the straight-walled trench to operate. When the trench excavation depth is large, collapse and landslide accidents caused by the instability of the trench wall are prone to occur, which affects safe construction operations to a certain extent. In order to protect construction workers from damage caused by trench wall landslides or collapses, a temporary support structure for pipeline trenches is required.

[0003] According to the search, Chinese patent literature, announcement number: CN217231869U, discloses a pipeline trench support structure, which supports fixed guard plates on both side walls of the trench relatively, and then uses an upper bracket to fix the two relatively fixed guard plates, and the movable guard plates slide forward from the fixed guard plates, and the movable guard plates are gradually supported on the side walls of the trench on both sides, and then the two movable guard plates are supported and fixed by the lower bracket, so that the support structure is easily assembled. However, the device cannot adjust and change its own width during actual use, so it is difficult to install and fix inside pipeline trenches of different widths, which has certain limitations; in addition, the overall volume of the device is large, so it has certain installation difficulties, resulting in a long construction time and low construction efficiency, which reduces the overall practicality. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a temporary support structure for a pipeline trench, which has the advantages of being able to adjust its own width to adapt to different pipeline trenches, facilitating installation and fixation, improving construction efficiency, and ensuring the safety of the working environment, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temporary support structure for a pipeline trench, comprising a protective plate, a square steel pipe is fixedly installed on the outer side surface of the protective plate, a shaft sleeve is fixedly installed on the outer side surface of the square steel pipe, a pin is installed inside the shaft sleeve, a connecting piece is fixedly installed on the inner side surface of the square steel pipe, a first screw is installed inside the connecting piece, a long sleeve is installed on the outer side surface of the first screw, and a second screw is installed inside the long sleeve.

[0008] Preferably, the protective plates and the square steel tubes are both provided in plural numbers, and the plural square steel tubes are installed on the left and right sides of the plural protective plates.

[0009] Through the above technical solution, multiple protective plates can effectively and temporarily support and reinforce trenches with an excavation depth of 1.5 meters to 3 meters, providing a safe and reliable working environment for construction workers; and multiple square steel pipes can not only enhance the overall stability of the device, but also facilitate the connection and installation of multiple devices together, thereby effectively constructing trenches of different lengths; in addition, protective plates and square steel pipes are modular steel components, which can be mass-produced, easy to transport, recycle and turn around, and further reduce production costs.

[0010] Preferably, the number of the shaft sleeves and the shaft pins are both multiple, and the multiple shaft pins are respectively installed inside the multiple shaft sleeves.

[0011] Through the above technical solution, multiple square steel pipes and parts such as protective plates can be effectively connected together by passing the pin shaft through the staggered sleeves. Therefore, different numbers and angles of connections can be effectively made according to the length and shape of the groove, thereby improving the overall practicality of the device. In addition, since the volume of a single protective plate and other parts is relatively small, it is more convenient to install and construct, thereby improving the overall construction efficiency.

[0012] Preferably, the bottoms of the plurality of pins are all configured as pointed ends.

[0013] Through the above technical solution, the pin is made of impact-resistant high-carbon steel. After the pin passes through the interior of the sleeve, it can be driven into the soil at the bottom of the trench by hammering for about 20 cm, thereby effectively sharing part of the pressure on the side wall, avoiding trench wall landslides or collapses, and improving the stability of the device.

[0014] Preferably, the first screw, the long sleeve and the second screw are provided in multiple numbers, and the multiple first screws and the multiple second screws are threadedly connected to the inside of the multiple long sleeves, and the outer sides of the multiple first screws and the multiple second screws are threadedly connected with anti-loosening nuts.

[0015] Through the above technical scheme, by rotating the long sleeve, the long sleeve can push the first screw and the second screw on both sides outward together. When the first screw and the second screw are respectively pushed into the interior of the connecting parts on the square steel pipes on both sides, the force can be effectively transmitted to the square steel pipes and the protective plates, and finally applied to the side wall soil to ensure the stability of the trench side walls and avoid collapse; then rotating the anti-loosening nut can effectively prevent the first screw and the second screw from loosening by themselves under vibration or other dynamic load conditions, thereby ensuring the stability and reliability of the connection; at the same time, the long sleeve is rotationally adjusted, so the staff can manually install it and adjust it according to the trench excavation width, thereby improving the overall convenience and applicability of the device.

[0016] Preferably, there are a plurality of connecting members, and pins are installed on the outer sides of the plurality of connecting members, and the first screw rod and the second screw rod are connected to the inside of the connecting members through the pins.

[0017] Through the above technical solution, multiple first screws and second screws can be respectively installed and fixed inside multiple connecting parts through pins to ensure that they will not separate or move due to vibration or external force, so that the first screw, the long sleeve and the second screw are more stable when supporting the groove, and it is also convenient for the staff to position them during installation, thereby improving the overall practicality of the device.

[0019] 1. The utility model can effectively connect multiple square steel pipes and parts such as protective plates together by passing the pin shaft through the staggered sleeves, so that different numbers and angles of connections can be effectively made according to the length and shape of the groove; multiple protective plates can temporarily and effectively support and reinforce the groove with an excavation depth of 1.5 meters to 3 meters, providing a safe and reliable working environment for construction personnel; and multiple square steel pipes can not only enhance the overall stability of the device, but also facilitate the connection and installation of multiple devices together, so as to effectively construct grooves of different lengths; in addition, the protective plates and square steel pipes are modular steel components, which can be mass-produced, convenient for transportation, recycling and turnover, and further reduce the production cost; then the pin shaft is driven into the soil at the bottom of the groove by hammering or other means for about 20 cm, so as to effectively share part of the pressure of the side wall, avoid the occurrence of groove wall landslide or collapse, and improve the stability of the device.

[0020] 2. The utility model can push out the first screw and the second screw on both sides together by rotating the long sleeve. When the first screw and the second screw are respectively pushed into the inside of the connecting parts on the square steel pipes on both sides, the force can be effectively transmitted to the square steel pipe and the protective plate, and finally applied to the side wall soil to ensure the stability of the side wall of the groove and avoid collapse; then rotating the anti-loosening nut can effectively prevent the first screw and the second screw from loosening by themselves under vibration or other dynamic load conditions, thereby ensuring the stability and reliability of the connection; at the same time, the long sleeve is adjusted by rotation, so the staff can manually install it and adjust it according to the trench excavation width, thereby improving the convenience and applicability of the device as a whole; multiple first screws and second screws can be respectively installed and fixed inside multiple connecting parts by pins, thereby ensuring that they will not be separated or moved due to vibration or external force, thereby making the first screw, the long sleeve and the second screw more stable when supporting the groove, and convenient for positioning when the staff installs, thereby improving the overall practicality of the device.
