Background
At present, China has great demand on bridges with sustainability and durability. The method provides a wide prospect for promoting the large-scale application of the whole bridge in China, but also brings a bottleneck problem between technical application and great requirements. In addition, because the whole bridge has no support and expansion joint, the existing common earthquake-proof design and construction measures such as earthquake-proof support or damping device are difficult to be applied. Therefore, a novel integral bridge research with good flexibility and strong deformability needs to be developed urgently, the interaction between the abutment of the lower structure and the soil, the pile foundation and the soil is reduced or weakened, and the seismic isolation and reduction damper device suitable for the integral bridge is provided.
Disclosure of Invention
The invention improves the problems, namely the technical problems to be solved by the invention are that the existing integral bridge has no support and expansion joint, and the existing common earthquake-proof design and construction measures such as earthquake-proof support or damping device and the like are difficult to be applied.
The specific embodiment of the invention is as follows: the utility model provides a novel attenuator device of hard and soft combination formula, is including the intraformational pile foundation of inserting that is located bridge girder both sides, the top of pile foundation is fixed with flexible abutment, and the outside of flexible abutment has the draw plate, the foam concrete seat has been pour on the soil layer of draw plate below, the foam concrete seat draws the portion and is located the horizontal supporting part of longitudinal support bottom to flexible abutment direction extension including the longitudinal support who is used for supporting the draw plate, horizontal supporting part is fixed with the elastomer, the longitudinal support portion is fixed with the rubber layer towards flexible abutment in proper order, be fixed with the stock that runs through the elastomer on the flexible abutment.
Further, the anchor rod has the steel sheet towards the welding of foam concrete seat one side, leave the interval between anchor rod and the rubber layer.
Furthermore, the elastic body is connected with the transverse supporting part of the foam concrete seat and the elastic body is connected with the anchor rod penetrating through the elastic body through shear force keys.
Furthermore, a manual channel is reserved on the inner side face of the foam concrete seat facing the flexible bridge abutment and behind the flexible bridge abutment.
Furthermore, a guide plate is supported on the upper portion of the flexible bridge abutment, and a bridge deck is laid on the guide plate and the upper surface of the main beam.
Further, a distance of 10mm is reserved between the anchor rod and the rubber layer.
The invention also comprises a construction method for constructing the rigid-flexible combined damper device, which comprises the following steps:
(1) excavating a soil layer, embedding a pile foundation in the soil layer, and arranging a foam concrete seat and a fixed rubber layer fixed on the longitudinal inner side of the foam concrete seat on the soil layer on the outer side of the pile foundation;
(2) pouring a flexible abutment on the pile foundation, and positioning and punching a hole at the position where the anchor rod is embedded in the elastomer to form a hole channel;
(3) fixing an elastic body on the foam concrete seat by using a shear key;
(4) adjusting the positions of all the pore passages, sequentially inserting the anchor rods into the pore passages of the elastic body from left to right and embedding the anchor rods into the flexible abutment, adjusting the positions of the anchor rods, fixing the embedded anchor rod devices, and fixing the anchor rods by using shear keys;
(5) and finally, integrally performing cast-in-place construction at the joint of the bridge girder, the guide plate and the flexible abutment, and filling soil behind the guide plate to complete installation.
Compared with the prior art, the invention has the following beneficial effects: according to the invention, by utilizing the material characteristics of the foam concrete seat (namely the rigid secondary abutment), the rubber layer, the flexible abutment and the elastomer with lower rigidity, under the external force load, the displacement deformation is realized through the longitudinal bridge movement of the embedded anchor rod, and the steel plate at the end part of the anchor rod acts on the rubber layer, so that the aims of damping and energy consumption of the damper are achieved.
Unlike conventional rigid abutments, the rigid-flexible modular abutment is constructed of a rigid sub-abutment formed of a flexible abutment and a foam concrete seat. The flexible main bridge abutment mainly bears vertical load of the main beam structure of the whole bridge and horizontal reciprocating deformation generated under the action of temperature, earthquake and the like, but does not need soil retaining or lateral soil pressure resisting. Therefore, compared with rigid or semi-rigid abutment and light thin-wall or thin-wall abutment, the flexible abutment has simpler and more definite stress, can fully exert the flexible performance and has better deformation capability. The rigid secondary abutment in the combined abutment is made of light foam concrete materials and mainly resists the action of the soil pressure on the rear side of the abutment. The rigid secondary abutment replaces part of the filling soil behind the abutment which is difficult to compact, easy to come off and settle and causes vehicle jumping, so that the driving comfort is greatly improved, and the impact effect of the vehicle is reduced; meanwhile, the amount of the earth filled behind the platform can be reduced, and the pressure effect of the earth behind the platform is further reduced.
Compared with the prior art, the embedded anchor rod acts on the rubber layer and the flexible bridge abutment, and the elastic material and other seismic isolation and reduction devices are filled between the embedded anchor rod and the flexible bridge abutment, so that the force transmission path and the force transmission mode are changed. The failure mode of the damper is changed instead of the condition that the traditional damper cannot be used due to aging. The distance and the number of the anchor rods can be adjusted according to the seismic fortification intensity, and the method is suitable for strong seismic areas. Simultaneously, can set up between the abutment with the whole abutment back void area of tradition, this region except being convenient for flexible abutment horizontal reciprocating motion, can also maintain or change intelligent sensing monitoring instrument through the detection maintenance passageway of reserving, the fine notion that has embodied toughness city, when the calamity takes place promptly, can bear the impact, reply fast, resume, keep city function normal operating to respond to future calamity risk better through the adaptation. The construction can be realized quickly, the construction period is shortened, and the manufacturing cost is saved. And the device is simple, convenient to assemble and disassemble, saves space and position and is beneficial to manual operation.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.
