Description

Technical Field

[0001] This utility model relates to the field of tunnel structure technology, specifically a pipeline reinforcement structure for road and bridge underpass tunnels. Background Technology

[0002] There are two main construction methods in the construction of urban underpasses: one is to erect formwork supports and pour concrete on-site, and the other is to prefabricate tunnel sections and assemble them through transportation and hoisting.

[0003] Underpass tunnels are mostly constructed using formwork supports and cast-in-place concrete, but this method has the problem of long construction periods and causes long-term disruption to urban traffic. In contrast, the construction mode of prefabricating tunnel sections or segments in a prefabrication plant and then assembling them on the construction site has the advantages of saving construction time, minimizing road disruption, and reducing environmental pollution, and has therefore received significant attention in this field.

[0004] In the construction of precast tunnels, the stability of the connection between tunnel blocks or tunnel sections is directly related to the safety of the underpass tunnel. Therefore, in order to achieve the stability of the connection between tunnel blocks or tunnel sections, a pipeline reinforcement structure for road and bridge underpass tunnels is provided.

[0033] The connecting component 2 includes a fixing plate 201, a connecting hole 202, and a fixing bolt 203;

[0034] The E-type top seat 101 and the E-type base 102 are joined by concave grooves 105 on both sides. The concave grooves 105 are provided with through holes 106 that pass through the E-type top seat 101, the E-type base 102 and the steel column 103.

[0035] The connecting hole 202 is opened on the side of the fixing plate 201 and completely penetrates the other side of the fixing plate 201. The fixing plate 201 is snapped into the inner side of the concave groove 105, and the positions of the connecting hole 202 and the through hole 106 correspond one-to-one.

[0036] The fixing bolt 203 passes through the connecting hole 202 and the concave groove 105 in sequence through the fixing plate 201, the E-type top seat 101, the E-type base 102, the plug-in steel column 103, and another fixing plate 201, and is tightened with a nut to realize the connection and fixation between the E-type top seat 101 and the E-type base 102.

[0037] The reinforcement component 3 includes a hexagonal block 301, a reinforcement rod 302, a threaded rod 303, and a fixing screw cylinder 305;

[0038] A storage groove 107 is provided at one end of the splice between the E-type top bracket 101 and the E-type base 102. A first round hole 108 is provided at one end of the storage groove 107 of the E-type top bracket 101 and the E-type base 102. The first round hole 108 completely penetrates both ends of an insertable steel post 103.

[0039] The fixing screw 305 is fixed inside another plug-in steel column 103 and is connected to the second round hole 109 for conduction;

[0040] Hexagonal blocks 301 and reinforcing rods 302 are connected and fixed horizontally in sequence. Hexagonal blocks 301 are distributed and stored inside the storage groove 107. Reinforcing rods 302 are distributed inside the first circular hole 108. Threaded rods 303 are distributed inside the second circular hole 109 and are threadedly connected to the fixing screw cylinder 305. This is used to reinforce the joint between the E-type top seat 101 and the E-type base 102.

[0041] The reinforcement component 3 also includes a connecting screw hole 304;

[0042] A connecting screw hole 304 is opened at one end of the hexagonal block 301 and extends through the interior of the reinforcing rod 302;

[0043] One end of the threaded rod 303 extends out to the outside of the E-type top seat 101 and the E-type base 102 and is threadedly connected to the connecting screw hole 304 on another set of reinforcement components 3, so as to realize the connection and reinforcement of the two sets of prefabricated tunnel components 1.

[0044] The outer diameter of the hexagonal block 301, the outer diameter of the reinforcing rod 302, and the outer diameter of the threaded rod 303 decrease sequentially, and the outer diameters of the reinforcing rod 302 and the threaded rod 303 match the inner diameters of the first circular hole 108 and the second circular hole 109, respectively.

[0045] In this embodiment, the assembly and splicing steps of this prefabricated tunnel component 1 are as follows:

[0046] First, the E-type base 102 is hoisted and placed in the designated position using hoisting equipment. Then, the E-type top seat 101 is hoisted above the E-type base 102, and the insertion slot 104 is connected to the insertion steel column 103, thus completing the initial connection between the E-type top seat 101 and the E-type base 102. The E-type top seat 101 and the E-type base 102 form an underpass tunnel.

[0047] Then, the two fixing plates 201 are respectively snapped into the concave grooves 105 on both sides of the splice of the E-type top seat 101 and the E-type base 102. Then, the fixing bolts 203 are passed through the connecting holes 202 and the through holes 106 and tightened with nuts. In this way, the E-type top seat 101, the E-type base 102 and the inserted steel column 103 are connected and fixed.

[0048] Next, the threaded rod 303 is inserted into the storage slot 107 and passes through the first round hole 108, the second round hole 109, and the fixing screw 305 in sequence. The threaded rod 303 and the fixing screw 305 are threadedly connected. Finally, the hexagonal block 301 is stored in the storage slot 107. The threaded rod 303 protrudes from the outer end of the E-type top seat 101 and the E-type base 102 (it should be noted that the length of the threaded rod 303 on the first set of prefabricated tunnel components 1 can be set to be flush with the outer end of the E-type top seat 101 and the E-type base 102). The reinforcement component 3 can further reinforce the E-type top seat 101 and the E-type base 102. In this way, the E-type top seat 101 and the E-type base 102 are fixed in the horizontal, longitudinal, and vertical directions.

[0049] This operation can then be repeated. It should be noted that when installing other prefabricated tunnel components 1, the threaded rod 303 on the next group of prefabricated tunnel components 1 is threadedly connected and fixed to the connecting screw hole 304 on the previous group of prefabricated tunnel components 1. This can achieve the connection and reinforcement of the two adjacent groups of prefabricated tunnel components 1 (it should be noted that the tightening direction of the threaded rod 303 to the connecting screw hole 304 is the same as the tightening direction of the threaded rod 303 to the fixing screw 305).

[0050] Please refer to this carefully. Figures 1-5 The top of the E-type top seat 101 is provided with a first grouting hole 110 that communicates with the concave groove 105, and the top of the E-type top seat 101 is also provided with a second grouting hole 111 that communicates with the receiving groove 107.

[0051] In this embodiment: After all the prefabricated tunnel components 1 are connected and reinforced, grouting can be performed through the first grouting hole 110 and the second grouting hole 111 to completely fill the inner cavity of the inserted steel column 103 and the inner cavity of the receiving groove 107. After the filling concrete has completely solidified, the connecting component 2, the reinforcing component 3 and the prefabricated tunnel component 1 are completely fixed together, thus further strengthening the splicing state of the prefabricated tunnel component 1.
