Embodiment
[0041] Example: such as figure 1 As shown, the composite steel pipe UHPC shock-absorbing pier of this embodiment is composed of an outer steel pipe 1, an inner steel pipe 2, a UHPC layer 3 and a rubber concrete layer 4;
[0042] The above-mentioned 2 inner steel pipes are set inside the above-mentioned outer steel pipe 1;
[0043] The UHPC layer 3 is filled between the inner wall of the outer steel pipe 1 and the outer wall of the inner steel pipe 2;
[0044] The rubber concrete layer 4 is filled inside the inner steel pipe 2 .
[0045] The inner steel pipe 2 of the entire composite steel pipe UHPC shock-absorbing pier can provide constraints on the rubber concrete layer 4, which can improve the bonding performance between rubber and concrete, and enhance the shock isolation and energy dissipation capacity of the rubber concrete layer 4; Provides strong constraints, overcomes the brittleness of UHPC layer 3, can make full use of the strength of outer steel pipe 1 and UHPC la...

The invention relates to the technical field of civil engineering, and especially relates to a composite steel pipe UHPC damping column pier. The composite steel pipe UHPC damping column pier is composed of an external steel pipe, an internal steel pipe, an UHPC layer and a rubber concrete layer; the internal steel pipe is sleeved in the external steel pipe, a part between the inner wall of the external steel pipe and the outer wall of the internal steel pipe is filled with the UHPC layer, and an internal part of the internal steel pipe is filled with the rubber concrete layer. The composite steel pipe UHPC damping column pier uses the advantages of steel pipe, UHPC and the rubber concrete, can better solve the anticorrosion problem of the steel pipe concrete, increases the endurance of amember, reduces the life-cycle cost of the member, and prolongs the life period of the member; the damping column pier has the advantages of energy saving and environmental protection, accords with continuous development requirement of green building idea and building industry; the member has the advantages of large carrying capacity reserve, good ductility, seismic performance and fatigue resistance, excellent shock resistance, and good damping performance, and has excellent seismic performance and good damping capability.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a composite steel pipe UHPC shock-absorbing pier. Background technique [0002] my country is one of the countries that produce the largest amount of waste rubber tires, and its consumption of rubber resources ranks among the top in the world. According to relevant data predictions, by 2020, the generation of waste rubber in my country will reach more than 6 million tons. Waste rubber is not easy to degrade, and it will pollute the environment after landfill, and incineration will bring air pollution. Simultaneously, if waste rubber can not be rationally utilized, it will also cause a waste of effective energy. The disposal of waste rubber and how to reasonably solve the resource utilization of waste rubber have become urgent problems to be solved. [0003] Rubber aggregate concrete is a new type of green environmental protection building material made by mixing rubb...
