Background
Most of the materials adopted by the existing bridges are reinforced concrete and steel, and in consideration of regionality, ecology and characteristic features, the bridges mainly dominated by human behaviors are made of wood and bamboo (such as remote mountainous areas and scenic areas), the wood and bamboo are ecological natural materials which are easy to obtain nearby materials, the materials are good in environmental protection in the whole life cycle, and the wood and bamboo bridges have more humanity features and regional features. Compared with wood, bamboo has the advantages of short growth period, tensile strength, elasticity and toughness, but the characteristics of hollow bamboo section and uneven diameter enable the connection mode to have greater difficulty and be difficult to utilize on the structural level. Therefore, the bamboo needs to be processed into the heavy bamboo which is a new bamboo material formed by reorganizing and strengthening the bamboo, namely, the section bar is formed by rolling and loosening bamboo chips or bamboo strips (raw bamboos), gluing, assembling along lines and pressing and gluing, and has the advantages of small density, high strength, good toughness, good earthquake resistance and the like.
A bamboo beam bridge is composed of a bridge span structure and a lower part structure. The bridge span structure of the bamboo girder bridge comprises a girder rib and a building component on the girder rib. The lower structure of the bamboo beam bridge comprises an abutment which is formed by pouring a stone concrete foundation, a stone concrete abutment body and a reinforced concrete abutment cap from bottom to top in sequence. A plurality of support base cushion stones are evenly arranged on the top surface of the reinforced concrete table cap at intervals, a rubber support base is arranged on the top surface of each support base cushion stone, and the central line of each support base cushion stone coincides with the central line of each rubber support base. And then, mounting two ends of the same beam rib with the rubber support, uniformly mounting a transverse partition plate between every two beam ribs at intervals, uniformly mounting a plurality of bamboo upright posts on the beam rib at intervals outside the beam bridge, and laying building components such as bamboo plates and the like right above the beam rib.

At present, the existing reinforced concrete bridge is generally installed and fixed by a way of installing a rubber support on a cast-in-place beam or a precast beam. A rubber support is installed on a cast-in-place beam, a supporting steel plate which is slightly larger than the plane of the rubber support is additionally arranged on the rubber support, anchoring steel bars are welded on the steel plate and connected with a beam body, the supporting steel plate is regarded as a part of a cast-in-place template for pouring, and the upper surface and the lower surface of the rubber support are completely attached to a beam bottom steel plate and the top surface of a support base stone. Because the abutment is different from the bamboo beam rib in structure, the method cannot be realized in a cast-in-place mode. The installation of the precast beam installation rubber support is characterized in that the beam bottom and the top surface of the support base cushion stone are parallel and flat as far as possible, so that the beam bottom and the upper surface and the lower surface of the support base cushion stone are completely attached to each other, and the occurrence of bias pressure, void and uneven support is avoided. Because the bamboo beam rib and the reinforced concrete beam rib are structurally different, the weight of the bamboo beam rib is lighter than that of the reinforced concrete beam rib, when the beam end of the bamboo beam rib is placed on the rubber support, the bottom of the beam cannot be completely attached to the upper surface of the rubber support, so that the rubber support is locally overloaded, stress is concentrated or generates bias voltage, the stress support is uneven, and the structure of the bamboo beam end of the beam is influenced.
