Further, 2 or 3 socket ends can be connected to the vertical surface of the transition step.

Furthermore, the shape of stock is the U-shaped, and the stock is pegged graft on two sets of adjacent first grafting through-holes, second grafting through-hole.

A method of using a temporary bridge, comprising:

digging a trench on the road surface, and placing a plurality of steel pipe monomers into the trench; inserting the socket end of the connector into the end part of the steel pipe monomer, and aligning the socket end with the first insertion through hole of the steel pipe monomer and the second insertion through hole of the socket end;

the anchor rod is inserted into the first inserting through hole and the second inserting through hole, and a bridge body and a connector which are formed by the steel pipe monomers are fixedly connected to form the temporary bridge.

Preferably, the earth is filled on the bridge body, and the trench is filled.

The invention has the technical effects that:

the invention is convenient to use, can effectively relieve the traffic pressure of rural highways, is used in a limited space, does not occupy excessive crossing time, can be built on the road in time after the road surface is excavated, can restore the road surface in time after the pipeline is installed, and ensures that the construction operation can not influence the traffic.

The invention is all metal products, the connection mode is mainly socket anchoring, so the installation and the disassembly are convenient, the practicability is stronger, and stronger bearing capacity can be formed by simple assembly.

The invention can solve the problems of traffic obstruction and difficult construction caused by large excavation, so that excessive continuous construction is avoided in the construction process, and the construction cost is effectively saved.

Detailed Description

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

As shown in fig. 1, is a schematic perspective view of the access bridge of the present invention; as shown in fig. 2, it is a schematic side structure of the connecting head of the present invention; FIG. 3 is a schematic top view of the connector of the present invention; fig. 4 is a schematic view of the anchor rod of the present invention; as shown in FIG. 5, it is a schematic structural view of the steel pipe of the present invention.

The structure of the access bridge comprises: the bridge comprises a bridge body 1, a connector 2 and an anchor rod 3; the bridge body 1 and the connector 2 are spliced together by an anchor rod 3. The connector 2 can be inserted at one end of the bridge body 1, and the connectors 2 can also be inserted at two ends of the bridge body 1 respectively.

The bridge body 1 comprises a plurality of steel pipe single bodies 11, and the steel pipe single bodies 11 are provided with first inserting through holes 12 at end positions. The steel pipe monomer 11 adopts DN100 thick-wall steel pipe.

The connector 2 includes: the transition step 21 and the socket end 22, the longitudinal section of the transition step 21 is triangular, and the end of the socket end 22 is connected to the vertical surface of the transition step 21. The inclined surface of the transition step 21 is provided with an anti-skid strip 23, and the socket end 22 is provided with a second socket through hole 24. The anti-slip strips 23 are made of angle steel, the inclined plane, the bottom surface and the vertical plane of the transition step 21 are all made of steel plates and are welded together, and two edges of the angle steel are welded on the inclined plane. The vertical surface of the transition step 21 can be connected with 2 or 3 socket heads 22. The socket end 22 adopts DN80 thick-wall steel pipe.

The anchor rod 3 is U-shaped, when one end of the steel pipe single body 11 is inserted into the socket end 22, the first inserting through hole 12 and the second inserting through hole 24 are overlapped, and the U-shaped anchor rod 3 is inserted into two adjacent groups of the first inserting through hole 12 and the second inserting through hole 24. Of course, the anchor rod 3 may be cylindrical in shape, with a pull ring or end cap provided at the end. The inner diameters of the first plug through hole 12 and the second plug through hole 24 are 20 mm.

During the use, according to the required width of temporary bridge, assemble the connector 2 and the steel pipe monomer 11 of different numbers, can overlap joint random width through the combination, form a temporary bridge, satisfy road traffic, do not influence the normal construction of pipeline yet simultaneously.

The use method of the temporary bridge specifically comprises the following steps:

step 1: digging a trench on the road surface, and placing a plurality of steel pipe monomers 11 into the trench;

step 2: inserting the socket end 22 into the end of the steel pipe single body 11, aligning the first inserting through hole 12 of the steel pipe single body 11 and the second inserting through hole 24 of the socket end 22, and enabling the first inserting through hole 12 and the second inserting through hole 24 to coincide;

and step 3: the anchor rod 3 is inserted into the first inserting through hole 12 and the second inserting through hole 24 to fixedly connect the bridge body 1 and the connector 2 to form the temporary bridge.

And 4, step 4: and (3) filling earthwork on the bridge body 1 consisting of a plurality of steel pipe monomers 11, and filling the trench.
