Description

Technical Field

[0001] This invention relates to the field of pre-embedded channel installation technology for integrated utility tunnels, specifically a positioning device for connecting and installing pre-embedded channels in integrated utility tunnels. Background Technology

[0002] Integrated utility tunnels are underground urban pipeline corridors, which are tunnel spaces built underground in cities to integrate various engineering pipelines such as electricity, communication, gas, heating, and drainage. They are equipped with dedicated inspection ports, hoisting ports, and monitoring systems. They are important infrastructure and "lifelines" to ensure the operation of cities. During the construction of integrated utility tunnels, it is usually necessary to pre-install embedded channels in the main building to provide support for the installation of the integrated utility tunnel. With the promotion and construction of integrated utility tunnel projects in mature urban areas, in areas where large-scale slope excavation is not feasible, the support system of the foundation pit support may affect the installation of the trench. In the areas where the installation of the buried trench is affected, the production and construction personnel will cut the pre-buried trench according to the actual situation and connect it after the support affecting the installation of the trench is removed. However, traditional channel connection methods are arbitrary, have low construction efficiency, and make it difficult to guarantee the positioning accuracy of channel installation. There are misalignments at the connection points between adjacent channels, which affects the subsequent sliding installation of supports and also affects the aesthetics of the entire pipe gallery.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning device for connecting and installing pre-embedded channels in integrated utility tunnels, in order to solve the problems mentioned in the background art, such as arbitrary connection methods for pre-embedded channels in integrated utility tunnels, low construction efficiency, difficulty in ensuring the positioning accuracy of channel installation, and misalignment at the connection points between adjacent channels, which affects the subsequent sliding installation of supports.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A positioning device for connecting and installing pre-embedded channels in a utility tunnel, used for connecting and positioning adjacent tunnel sections, includes: The positioning component includes a positioning steel plate fitted onto the upper part of the connection between adjacent pipe gallery sections for positioning the pipe gallery sections; The locking assembly includes a threaded rod extending from the inside of the pipe rack section to above the positioning steel plate, a locking nut threaded to the outside of the threaded rod for locking the positioning steel plate, and a bolt head fixedly connected to the lower end of the threaded rod and located inside the pipe rack section.

[0006] Furthermore, the lower end of the positioning steel plate is provided with a groove for accommodating the pipe gallery section; The positioning steel plate has a through hole inside and outside the screw for passing through the screw.

[0007] Furthermore, the locking assembly also includes: A washer, placed between the positioning steel plate and the lock nut, is used to engage with the lock nut to tighten the positioning steel plate. The screw has a thread on its outer side that is compatible with the locking nut; The diameter of the screw is smaller than the diameter of the through hole.

[0008] Furthermore, the interior of the pipe gallery section is provided with a channel area; The upper end of the channel area is provided with an opening area; The width of the opening area is smaller than the width of the channel area.

[0009] Furthermore, extension blocks are fixedly connected to both sides of the bolt head to limit the bolt head in conjunction with the top wall of the channel area; The diameter of the bolt head is smaller than the width of the opening area.

[0010] Furthermore, the lower end of the utility tunnel section is fixedly connected to a bracket to support the adjacent utility tunnel sections after they are connected and positioned.

[0011] Furthermore, the upper wall inside the channel area is provided with a slot for accommodating and limiting the extension block.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention aligns two sets of pipe rack sections to be connected, and inserts a positioning steel plate into the connection end of the two sets of pipe rack sections to initially limit the pipe rack sections. Then, the pipe rack sections are fastened together with the positioning steel plate by locking nuts, screws and bolt heads, so that the adjacent pipe rack sections are fastened together.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-5 The present invention provides a technical solution: A positioning device for connecting and installing pre-embedded channels in a utility tunnel, used to connect and position adjacent utility tunnel sections 100, includes: The positioning component 2 includes a positioning steel plate 21 on the upper part of the pipe gallery section 100 that is sleeved at the connection of adjacent pipe gallery sections 100 for positioning the pipe gallery section 100; The locking assembly 1 includes a screw 12 extending from the inside of the pipe gallery section 100 to the top of the positioning steel plate 21, a locking nut 13 threaded to the outside of the screw 12 for locking the positioning steel plate 21, and a bolt head 11 fixedly connected to the lower end of the screw 12 and located inside the pipe gallery section 100.

[0017] It should be noted that by aligning the two sets of pipe rack sections 100 to be connected, and by fitting the positioning steel plate 21 onto the connecting end of the two sets of pipe rack sections 100, the pipe rack sections 100 are initially limited. Subsequently, the pipe rack sections 100 are fastened to the positioning steel plate 21 by using the locking nut 13 in conjunction with the screw 12 and the bolt head 11, so that the adjacent pipe rack sections 100 are fastened together. This achieves accurate installation and positioning of the pipe rack sections 100, avoiding misalignment at the connection between adjacent channels.

[0018] As an improvement, such as Figure 2-3 As shown, the lower end of the positioning steel plate 21 is provided with a groove 23 for accommodating the pipe gallery section 100; The positioning steel plate 21 has a through hole 22 inside and outside the screw 12 for passing through the screw 12.

[0019] Furthermore, such as Figure 2 As shown, the locking assembly 1 further includes: Washer 14 is located between the positioning steel plate 21 and the locking nut 13, and is used to engage with the locking nut 13 to tighten the positioning steel plate 21. The screw 12 has a thread on its outer side that is compatible with the locking nut 13; The diameter of the screw 12 is smaller than the diameter of the through hole 22.

[0020] Furthermore, the interior of the pipe gallery section 100 is provided with a channel area 1001; The upper end of the channel area 1001 is provided with an opening area 1002; The width of the opening region 1002 is smaller than the width of the channel region 1001.

[0021] Among them, such as Figure 3 , Figure 5 As shown, extension blocks 111 are fixedly connected to both sides of the bolt head 11, which are used to limit the bolt head 11 in conjunction with the top wall of the channel area 1001. The diameter of the bolt head 11 is smaller than the width of the opening area 1002.

[0022] As an improvement, a bracket 101 is fixedly connected to the lower end of the pipe gallery section 100 to support the adjacent pipe gallery sections 100 after they are connected and positioned.

[0023] Furthermore, such as Figure 3 , Figure 5 As shown, the upper inner wall of the channel area 1001 is provided with a slot 1003 for accommodating and limiting the extension block 111.

[0024] It should be noted that: in the specific implementation process of this invention, such as Figure 1-5 As shown, first align the two sets of pipe rack sections 100 to be connected. Then, insert multiple bolt heads 11 along with extension blocks 111 into the channel area 1001. Next, rotate the screw 12 so that the screw 12 drives the extension blocks 111 to align with the slots 1003 through the bolt heads 11. This allows the groove 23 at the lower end of the positioning steel plate 21 to initially fit with the pipe rack section 100, and the screw 12 passes through the through hole 22. Then, fit the washer 14 onto the outside of the screw 12 and screw the lock nut 13 into the screw. On the outside of 12, rotate the locking nut 13. The locking nut 13 pushes the washer 14 and, together with the bolt head 11 and the extension block 111, locks the positioning steel plate 21 to the pipe rack section 100. At this time, the extension block 111 and the upper wall of the slot 1003 are in a tight state, completing the connection and installation of the adjacent pipe rack section 100. By locking and positioning the pipe rack section 100 with the positioning steel plate 21, the adjacent pipe rack section 100 can be installed accurately, ensuring that the connection of the pipe rack section 100 is aligned.
