Description

Technical Field

[0001] The invention relates to a road construction technology, in particular to a temporary bridge and a use method thereof. Background Art

[0002] Pipeline welding is an important process in long-distance pipeline projects. Natural gas pipelines frequently cross rural paved roads. Some cement roads are the only main roads into the village and have a large volume of traffic. Small family cars and small earth-moving vehicles usually pass by frequently.

[0003] Crossing usually adopts the method of large excavation to pass through the rural paved road. Once the road surface is damaged, the village will be cut off from the outside world, and the transportation in the village will be inconvenient, which will bring difficult coordination problems to the construction. If the road is not excavated temporarily and too many joints are left, it will greatly increase the difficulty of construction and lead to an increase in construction costs. Summary of the invention

[0014] The anchor rod is inserted into the first plug-in through hole and the second plug-in through hole to connect and fix the bridge body and the connecting head composed of multiple steel pipe monomers to form a temporary bridge.

[0015] Preferably, earth is buried on the bridge body to fill the trench.

[0025] The following description sufficiently illustrates specific embodiments of the invention to enable those skilled in the art to practice and reproduce the invention.

[0026] like Figure 1 As shown in FIG. 1 , it is a schematic diagram of the three-dimensional structure of the temporary bridge in the present invention; Figure 2 , which is a schematic diagram of the side structure of the connector in the present invention; Figure 3As shown in FIG. 1 , it is a schematic diagram of the top structure of the connector in the present invention; Figure 4 As shown in FIG. 1 , it is a schematic diagram of the structure of the anchor rod in the present invention; Figure 5 The figure is a schematic diagram of the structure of the steel pipe monomer in the present invention.

[0027] The structure of the temporary bridge includes: a bridge body 1, a connector 2, and an anchor rod 3; the bridge body 1 and the connector 2 are plugged together by the anchor rod 3. The connector 2 can be plugged at one end of the bridge body 1, or one connector 2 can be plugged at each end of the bridge body 1.

[0028] The bridge body 1 comprises a plurality of steel pipe monomers 11, and the steel pipe monomers 11 are provided with first plug-in through holes 12 at the end positions. The steel pipe monomers 11 are DN100 thick-walled steel pipes.

[0029] The connector 2 includes: a transition step 21 and a socket end 22. The longitudinal section of the transition step 21 is a triangle, and the end of the socket end 22 is connected to the vertical surface of the transition step 21. An anti-slip strip 23 is provided on the inclined surface of the transition step 21, and the socket end 22 is provided with a second plug-in through hole 24. The anti-slip strip 23 is made of angle steel, and the inclined surface, bottom surface and vertical surface of the transition step 21 are all steel plates and welded together, and the two edges of the angle steel are welded to the inclined surface. Two or three socket ends 22 can be connected to the vertical surface of the transition step 21. The socket end 22 uses a DN80 thick-walled steel pipe.

[0030] The shape of the anchor rod 3 is U-shaped. When one end of the steel pipe unit 11 is plugged into the socket end 22, the first plug-in through hole 12 and the second plug-in through hole 24 overlap, and the U-shaped anchor rod 3 is plugged into two adjacent groups of the first plug-in through hole 12 and the second plug-in through hole 24. Of course, the shape of the anchor rod 3 can also be columnar, with a pull ring or end cap at the end. The inner diameter of the first plug-in through hole 12 and the second plug-in through hole 24 is 20 mm.

[0031] When in use, different numbers of connectors 2 and steel pipe monomers 11 are assembled according to the required width of the temporary bridge. Through the combination, any width can be overlapped to form a temporary temporary bridge to meet road traffic without affecting the normal construction of the pipeline.

[0032] The method of using the temporary bridge includes the following steps:

[0033] Step 1: digging a trench on the road surface and placing a plurality of steel pipe monomers 11 into the trench;

[0034] Step 2: Insert the socket end 22 into the end of the steel pipe monomer 11, align the first plug-in hole 12 of the steel pipe monomer 11 and the second plug-in hole 24 of the socket end 22, so that the first plug-in hole 12 and the second plug-in hole 24 overlap;

[0035] Step 3: Insert the anchor rod 3 into the first plug-in through hole 12 and the second plug-in through hole 24, and connect and fix the bridge body 1 and the connector 2 to form a temporary bridge.

[0036] Step 4: Fill the bridge body 1 composed of multiple steel pipe monomers 11 with earth to fill the trench.

[0037] In this way, a loaded truck drives into the bridge body 1 from the connector 2, and then drives onto the road surface through the bridge body 1. Since the transition step 21 is provided with an anti-skid strip 23 on the inclined surface, the loaded truck can be prevented from slipping. The bridge body 1 and the connector 2 are connected as a whole with a large bearing capacity. After use, the temporary bridge can be disassembled and taken away by pulling up the anchor rod 3 for reuse next time.

[0038] The terms used in the present invention are illustrative and exemplary, rather than restrictive. Since the present invention can be implemented in various forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
