In addition, there are bridges constructed with light concrete, aluminum alloy, glass fiber reinforced plastic and other building materials. The bridge constructed by adopting the lightweight concrete is mostly a simple bridge with small carrying capacity. For example, for rural areas with vast expanses in China, especially rural areas in southern areas, the bridge is built according to mountains and water, and the building significance of the simple bridge is huge. However, although the traditional bridge has a long history, the shape and the system can bear some cultural factors, the hidden structural danger of the traditional bridge is not negligible, and the traditional bridge usually occupies a large space. Therefore, the reconstruction is generally recommended for most rural simple bridges, except for some bridges which are excellent in design, firm in structure and quite representative in meaning and still have a reserved value. The method not only can greatly facilitate the lives of villagers, strengthen the communication between the villagers and the outside, but also is beneficial to the development of village economy. In consideration of cost factors, the existing simple bridge is mostly built by adopting light concrete prefabricated parts, steel prefabricated parts or glass fiber reinforced plastics and other building materials.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Various aspects and features of the present invention are described herein with reference to the drawings.
These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment, given as a non-limiting example, with reference to the accompanying drawings.
It should also be understood that, although the invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of the invention, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
The above and other aspects, features and advantages of the present invention will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.
As shown in fig. 1 to 4, in one aspect, the present invention provides a simple bridge easy to construct, which is installed between two banks of a river and is used for pedestrians or vehicles 100 to pass through, and is particularly suitable for a section with a small traffic flow in a rural area and between rivers or ravines with low load requirements, so as to mainly facilitate the passage of pedestrians, livestock or small vehicles with a small flow, in the present invention, all components can be formed by splicing concrete prefabricated components, and a bridge body 1 thereof can specifically include: the first structure bodies 11 are oppositely arranged at two sides of the river channel to form a supporting foundation; in fig. 1 to 4, the first structure body 11 is shown as a whole, but it is understood that the structure formed by splicing different types of precast concrete members is also an acceptable and mature implementation. The second structure 12, which is similarly provided, can also be configured in the same manner. Two second structures 12 are also oppositely arranged and respectively combined on one side of the first structure 11 close to the center line of the river channel, and together with the first structure 11, the second structures form a first supporting surface (not shown in the figure) on the top; in consideration of river factors, of course, in the present invention, a plurality of pier structures 13 may be provided according to a river span, which are provided between two of the second structures 12, the plurality of pier structures 13 together constituting a second support surface (not shown) at the top thereof, the second support surface being coplanar with the first support surface; the pavement member 200 is composed of a plurality of prefabricated plates (not marked) and is respectively spliced and laid on the first supporting surface and the second supporting surface; the precast slab can be a wood slab, a steel slab or a concrete precast slab with lower cost. The above-described configuration actually constitutes the basic configuration of the passable bridge 1. The pier structure 13 may be a solid member to increase a supporting performance in consideration of a load bearing of the bridge and a river runoff amount, or may be a hollow structure to facilitate a flow of water therethrough. Preferably, however, the pier structure 13 includes a hollow prefabricated shell 131 and a concrete-made filling block 132 inserted in the prefabricated shell 131.
Further, in consideration of safety, it is preferable that the pavement member 200 is provided with a side guard rail 17 along a length direction thereof and a separation guard rail 19 at a central position thereof, as shown in fig. 1 and 2, and the side guard rail 17 and/or the separation guard rail 19 are formed of a plurality of precast concrete members. The concrete prefabricated elements used here to form the side barriers 17 and the barrier barriers 19 can in fact be similar to most of the road barriers of the prior art and are therefore not described much. That is, it may be cast in one piece or may have multiple members joined together. However, in the present invention, it is preferable that the side guard rail 17 includes at least a first member 171 on the first support surface and a plurality of second members 172 on the second support surface, and the first member 171 and the second members 172 are connected by a rigid cross bar 173 penetrating both. In fact, the river position, i.e., the side guard rail disposed above the pier structure, is a grid-shaped guard rail formed by the spaced second members 172 and the rigid cross bars 173, which improves the landscape effect. When the side guard rails 17 are specifically provided, in particular, in some embodiments of the present invention, it is preferable that, as shown in fig. 1 and 6, the top supporting surface of the first structural body 11 is positioned higher than the top supporting surface of the second structural body 12 with a height difference D therebetween; the top supporting surfaces of the two opposite second structural bodies 12 correspond to the positions of the opposite outer sides of the side guard rails 17, side filling members 176 with the L-shaped cross sections are arranged, the supporting surfaces of the side filling members 176 and the top supporting surface of the first structural body 11 are coplanar and form the first supporting surface together, and the side guard rails 17 are fixedly arranged on the supporting surfaces of the side filling members 176. In such a configuration, the side rail 17 is restrained from falling off the deck by the side filling members 176 even when impacted.
In terms of improving safety, as shown in fig. 1 and 3, the present invention may further consider that a plurality of bridge seismic pedestals 15 for supporting the pavement member 200 are provided on the pier structure 13 under the second supporting surface. Fig. 7 shows a specific structure of the bridge seismic isolation foundation 15 according to the present invention, and as shown in the figure, the bridge seismic isolation foundation 15 is also an integrally assembled prefabricated member, and specifically includes a base 151, one side of the base 151 is fixed on the pier structure 13, and the other side of the base is opened to form a receiving structure, the receiving structure contains an elastic member 152 and a piston member 153 which is also arranged in the receiving structure and is located above the elastic member 152 to perform a piston motion, a rigid pad 154 made of steel is arranged above the piston member 153, and a top plate 155 connected to the pavement member. It can be seen that in such a structure, the transmission and absorption of deck vibrations can be achieved at low cost, preventing resonant damage to the bridge. In addition, referring to fig. 7, it can be seen that a caulking groove 1531 is formed on the outer periphery of the piston member 153, and the caulking groove 1531 may cooperate with a rubber sealing ring (not shown) to form a relatively sealed connection, so as to enhance the buffering and energy absorption effects.
As shown in fig. 1 and fig. 3, in rural areas, the bridge deck may be easily polluted due to more occasions for livestock and transportation of agricultural production materials, and especially for livestock manure, the appearance is affected and the potential safety hazard of driving is increased. Therefore, in the present invention, as shown in fig. 3, it is preferable that a water collection tank 16 for collecting rainfall be provided between the plurality of bridge seismic bases 15, a water recovery mechanism 18 for collecting water accumulated on the road surface is provided on the road surface member 200, and the water recovery mechanism 18 is communicated with the housing chamber 161 of the water collection tank 16. The recovered surface water can play a role in promoting the safety of pedestrians, and meanwhile, the collected rainwater can be temporarily stored in the water collecting tank 16. As shown in fig. 3, the water recovery mechanism 18 may include a dewatering well grate 181 disposed on the pavement member 200, a downpipe 183 connected to the dewatering well grate 181, and a control valve 182 disposed on the water collection tank 16, wherein the downpipe 183 is connected to the water collection tank 16, and the water collection tank 16 is further provided with a water outlet pipe 162 controlled by the control valve 182. This outlet pipe 162 can carry out periodic cleaning to the bridge floor with a washing cleaning device (for example, small-size pressurization squirt) cooperation, compares with direct river course water intaking, and this mode had both solved the bridge floor ponding problem, still provides convenience for the bridge floor washing simultaneously.
In addition, in the present invention, as shown in fig. 4, even when the pier structure 13 is prefabricated as the solid concrete, there may be a safety hazard in the simple bridge in coping with a sudden increase in surface runoff due to heavy rainfall, and for this reason, it is preferable in some embodiments that a plurality of connecting beams 133 are provided between a plurality of pier structures 13 in a direction in which the pavement member 200 extends in length. The connecting beams 133 can connect the plurality of pier structures 13 as a whole, and improve the flood resistance.
Also in consideration of flood resistance, as shown in fig. 2 and 5, in the present invention, it is preferable that the first member 11 is constructed in a hexahedral shape having a bottom surface in a parallelogram shape and a top surface in a right trapezoid shape, and the second member 12 is constructed in a hexahedral shape having a bottom surface in a right trapezoid shape and a top surface in a rectangular shape. That is, the first member 11 and the second member 12 are not regular hexahedral shapes, which is advantageous in forming a contact surface that is not parallel or tangential to the river discharge direction at any instance, and that may be flat or curved so long as it is not parallel or tangential to the river discharge direction, thereby providing the greatest resistance to discharge. In fig. 2, the two angles of the right trapezoid of the top side of the first component 11 are shown, respectively, angle c and the angle d complementary thereto, while in fig. 5, the angles of the right trapezoid of the bottom side of the second component 12 are shown, respectively, angle a and the angle b complementary thereto. In fact, to facilitate the prefabrication process, in some preferred embodiments, the included angle c is equal to the included angle b, and the included angle d is equal to the included angle a.
Furthermore, for some river channels in southern areas of our country, for example, because the soil is loose, in some embodiments, as shown in fig. 6, it may be considered that the two sides of the river channel are pre-constructed and constructed by combining the river channel laying member 300 provided in this embodiment, and the portion of the bridge 1 is completely the same as the above-mentioned embodiments. As shown in fig. 6, the river course laying member 300 may include a tetrahedral support structure 301 constructed at both sides of the river course and a wedge-shaped support structure 302 coupled to one side of the tetrahedral support structure 301 (actually, a hexahedron with two corresponding surfaces opened along the flow direction of the river) near the center line of the river course. Referring to fig. 6, it can be seen that the tetrahedral support structure 301 is actually a cylindrical structure, facilitating flood discharge when runoff increases. Also included is the wedge-shaped support structure 302, which also ensures the construction of the joint with the first structure 11. In this embodiment, the river course laying member 300 can effectively cope with bridge safety hazards caused by soft river course soil layers, and meanwhile, the problem that the traditional bridge construction is not easy and the cost is changed is avoided.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
