Description

Technical Field

[0001] This utility model relates to the field of tunnel segment technology, and more specifically, to high-strength precast tunnel segments. Background Technology

[0002] High-strength precast tunnel segments are precast concrete components used in the construction of underground engineering projects such as tunnels and underground pipelines. They are characterized by high strength, good durability, and excellent waterproof performance. They are usually cast in molds and prefabricated in factories, and different sizes and shapes can be customized as needed.

[0003] Currently, precast tunnel segments are mainly connected by connecting blocks at one end and connecting grooves at the other end. This allows the segments to connect with each other, forming a ring-shaped support pipe. However, the adjacent segments on both sides are not connected, so each arc-shaped support pipe can only bear the pressure of the channel alone. Although this makes the ring-shaped support pipe easy to disassemble, it reduces the overall load-bearing capacity and overall strength of the support pipe. Utility Model Content

However, the adjacent pipe segments on both sides are not connected together, so each arc-shaped support pipe can only bear the pressure of the channel alone. Although this makes the ring-shaped support pipe easy to disassemble, it reduces the overall load-bearing capacity of the support pipe and reduces the overall strength of the support pipe.

[0020] Please see Figure 2 and Figure 3 The segment assembly 1 includes a segment body 101. Rectangular connecting grooves 102 are formed on both sides of the segment body 101 away from the first connecting component 2, and an arc connecting groove 103 is formed on the end of the segment body 101 away from the arc connecting component 3. A plurality of first arc connecting steel bars 104 are connected to the inner cavity of the segment body 101.

[0021] Please see Figure 3 A number of second arc-shaped connecting steel bars 105 are connected in the inner cavity of the end of the segment body 101 away from the first arc-shaped connecting steel bar 104. A number of reinforcing ribs 106 are connected in the gap between the first arc-shaped connecting steel bar 104 and the second arc-shaped connecting steel bar 105, and the first arc-shaped connecting steel bar 104, the second arc-shaped connecting steel bar and the reinforcing ribs 106 form an arc-shaped support frame.

[0022] Please see Figure 4The first connecting component 2 includes a connecting block 201. A plurality of rectangular steel bars 202 are connected in the inner cavity of the connecting block 201. A plurality of vertical reinforcing bars 204 are connected in the inner cavity of each rectangular steel bar 202. A plurality of horizontal reinforcing bars 205 are connected in the inner cavity of each rectangular steel bar 202. A plurality of second reinforcing bars 203 are connected in the inner cavity of the connecting block 201. When the rectangular steel bars 202 are connected to the vertical reinforcing bars 204, a plurality of rectangular holes are formed. A reinforcing bar 106 provided on one end of the segment body 101 near the connecting block 201 is located in the inner cavity of the rectangular holes. The reinforcing bars 106 and the vertical reinforcing bars 204 are then connected by the horizontal reinforcing bars 205.

[0023] Each rectangular steel bar 202 is connected by a second reinforcing bar 203, and each vertical reinforcing bar 204 is connected by a horizontal reinforcing bar 205. The rectangular steel bar 202, the vertical reinforcing bar 204, the second reinforcing bar 203 and the horizontal reinforcing bar 205 form a steel bar support frame. A part of the steel bar support frame is located in the inner cavity of the rectangular connecting block 201, and the other part is located in the inner cavity of the segment body 101.

The connecting block 201 in the arc-shaped connecting component 3 is an arc-shaped connecting block, while the connecting block 201 in the first connecting component 2 is a rectangular connecting block.

[0025] Working principle: First, rectangular steel bars 202, vertical reinforcing bars 204, second reinforcing bars 203 and horizontal reinforcing bars 205 are welded together to form a steel support frame. Then, reinforcing bars 106 pass through the rectangular holes formed by connecting the rectangular steel bars 202 and the vertical reinforcing bars 204, and the steel support frame is fixed together with the reinforcing bars 106 through the horizontal reinforcing bars 205. Finally, the first arc-shaped connecting steel bars 104, the second arc-shaped connecting steel bars 105 and the reinforcing bars 106 are welded together to form the segment support frame.

At this time, by aligning the first connecting component 2 with the rectangular connecting groove 102, and then aligning the arc connecting component 3 with the arc connecting groove 103, the segment is connected to the segments in the four directions, thereby improving the connection strength of adjacent segments and thus improving the support strength of the pipeline.
