Description
Technical Field
The utility model relates to an arch bridge building engineering technical field specifically is a from anchor formula steel buckled plate rubble combination arch bridge.
Background
Currently, China has become the world with the largest number of tunnels, the most complex situation and the fastest development. Particularly, in the construction of tibet lines, when a lot of temporary bridges need to be built for passing, the realization of fast building of temporary bridges becomes an inevitable choice for the construction of tibet lines in the face of more and more severe transportation problems. The steel buckled plate is a novel building material, and the ductility of steel buckled plate itself is good, anti deformability is strong, and the installation is swiftly convenient simultaneously, saves the time limit for a project, still has with low costs, does benefit to advantages such as environmental protection, consequently in traffic engineering and municipal works, adopts steel buckled plate preparation culvert, tunnel, underpass and underground piping in a large number to become a trend. However, in some arch bridge engineering structures with large span, large load bearing capacity and high strength requirement, reinforced concrete structures are also frequently used. The arch bridge of the reinforced concrete structure has the advantages that the concrete crushing performance can be caused to fall off when the reinforced concrete structure is aged or vibrated, safety accidents are caused, meanwhile, templates are required to be built when the reinforced concrete arch culvert is constructed, time and labor are wasted, and finally the arch bridge is required to be dismantled, so that the construction process is increased, the construction time is prolonged, the construction efficiency is reduced, and the arch bridge is not green and environment-friendly due to the use of concrete. In some situations where the environmental requirements are strict and a bridge needs to be built up quickly, the arch bridge scheme of the reinforced concrete structure is not applicable. Therefore, it is necessary to realize a green and environment-friendly construction scheme for quickly building a temporary bridge.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present invention aims to provide a self-anchored arch bridge with corrugated steel plates and crushed stone combination, which can be built up temporarily and has the advantages of high strength and high bearing capacity; concrete is not needed, so that the environment is protected; need not build and pour the template, the construction is convenient fast, and can build the dismantlement repeatedly, utilizes many times. The technical scheme is as follows:
a self-anchored steel corrugated plate and gravel combined arch bridge comprises an external structure of a steel corrugated plate in a hexahedron box shape and gravel filled inside the steel corrugated plate; the bottom and the top steel buckled plate of steel buckled plate outer structure are the arch to through the stock anchor, through horizontal anchor rope anchor between the steel buckled plate of both sides.
Furthermore, two ends of the bottom of the arch bridge are connected with thin rods.
Furthermore, abutment foundations are arranged at two ends of the arch bridge.
Furthermore, the anchor rod is perpendicular to the bottom and top steel corrugated plates, and the upper end of the anchor rod penetrates through anchor holes of the top steel corrugated plate and is fixed through a top surface nut; the lower end of the bottom steel corrugated plate penetrates through the anchor hole of the bottom steel corrugated plate and is fixed through the bottom nut.
Furthermore, two ends of the transverse anchor cable penetrate through anchor holes of the steel corrugated plates on two sides and are fixed through side nuts.
The utility model has the advantages that: the utility model discloses can realize buildding bridge structures fast, have the advantage that intensity is high, bearing capacity is strong, can need not to use the concrete, green need not build the template, and the construction is convenient fast, saves the time limit for a project, improves the efficiency of construction. And can be repeatedly built and disassembled, and can be repeatedly utilized, thereby saving the fund.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the utility model discloses a from anchor formula steel buckled plate rubble combination arched bridge comprises polylith steel buckled plate shell, is six box shape, and bottom steel buckled plate is crooked into the arch, and both sides face steel buckled plate is connected by horizontal anchor rope 5. The bottom of the arch bridge is connected with a thin rod 4. The interior is filled with gravel 2, and the gravel becomes a whole with certain bearing capacity by embedding the anchor rods 3. A plurality of stock 3 are in bottom steel buckled plate top equipartition, and stock 3 is perpendicular with the steel buckled plate, and the stock is full of with the direct space of steel buckled plate by 2 fillings of rubble.
The outer structure 1 of the steel corrugated plate is composed of 6 steel corrugated plates, the bottom steel corrugated plate is bent into an arch shape, 4 steel corrugated plates are respectively connected with the bottom plate, welding is adopted, a cover-free box-packed pentahedron is formed by enclosing, after the broken stone is filled, the top steel corrugated plate is connected with a top nut through an anchor rod, and welding is adopted when necessary.
The structure enables the broken stone to have bearing capacity through the anchoring effect of the anchor rod, and can realize an arch bridge structure which is quick to build, high in strength and strong in bearing capacity; the steel corrugated plate sheets opposite to the side surfaces are connected by the anchor cables, so that the steel corrugated plate sheets on the two sides can firmly surround the gravel. The thin rods 4 are connected with two ends of the bridge, so that the integral bearing capacity is improved.
As shown in fig. 2 and 3, a plurality of anchor rods 3 are uniformly distributed on the bridge surface of the steel corrugated plate filled with broken stones, the anchor rods 3 are perpendicular to the bottom and top steel corrugated plates, and the upper ends of the anchor rods 3 penetrate through anchor holes of the top steel corrugated plate and are fixed through top surface nuts 8; the lower end of the bottom steel corrugated plate penetrates through the anchor hole of the bottom steel corrugated plate and is fixed through the bottom nut 6. As shown in fig. 4, two ends of the transverse anchor cable 5 pass through the anchor holes of the steel corrugated plates at two sides and are fixed by the side nuts 7. The anchor cables are connected to restrain the surrounding plates, so that the broken stones are firmly filled.
During construction, an anchor rod is preset and gravel is filled in the anchor rod. Specifically, the left steel corrugated plate, the right steel corrugated plate and the bottom steel corrugated plate are assembled to form a roof-free structure, the steel corrugated plates on the side faces are connected through transverse anchor cables, broken stones are filled in the steel corrugated plates after radial anchor cables on the bottom are preset, the steel corrugated plates on the top are connected after the broken stones are filled, and then anchor cable pre-pressure is applied.
Of course, the connection mode between the six box-shaped steel corrugated sheets can be various, and the connection mode between the six box-shaped steel corrugated sheets can be regarded as the connection mode of the structure which can ensure the strength required by the box-shaped structure.
