Problems solved by technology

[0003] The inventors found that although traditional steel pipe concrete has the advantages of high bearing capacity, good seismic performance, and convenient construction, with the continuous popularization of its application and the increase of service time, a series of problems such as unstable construction, void, and sticking, corrosion of steel pipes, local buckling of pipe walls, etc., it is difficult to effectively utilize the respective material advantages of steel structures and concrete; It is difficult to effectively protect the bridge pier when the impact force of the vehicle (ship) is relatively large, and the measures and structures that use new energy-dissipating materials to enhance the anti-collision and energy-dissipating characteristics of the bridge pier must be specially made, and the cost is high and the scope of application is small. Difficult to be widely applied to the anti-collision design of bridge piers

Embodiment 1

[0037] In a typical implementation of the present application, such as Figure 1-Figure 3 As shown, a corrugated steel pipe-rubber concrete fabricated bridge pier with energy dissipation and shock absorption is proposed.

[0038] It includes a bearing platform 1, a supporting column 3, and a cover beam 4. A first flange is provided between the bearing platform and the supporting column, and a plurality of fixed steel bars 2 are fitted in the ring direction of the first flange. One end is buried in the cap, and the other end passes through the second flange 3-1 preset at the lower end of the support column to connect the cap and the support column. The interior of the support column is provided with longitudinal reinforcement, and the upper end of the longitudinal reinforcement extends out of the support On the top surface of the column, the cover beam is provided with a channel corresponding to the upper end of the longitudinal steel bar. The cover beam is installed on the suppo...

Embodiment 2

[0052] In another typical embodiment of the present application, a construction method for the energy-dissipating and shock-absorbing corrugated steel pipe-rubber concrete fabricated bridge pier described in Embodiment 1 is provided.

[0053] Filling construction, pouring caps, reserved pouring opening:

[0054] When pouring the cap, the radius of the reserved groove opening on the top surface of the cap is slightly larger than that of the composite pier;

[0055] Embedded first flange and fixed reinforcement:

[0056] The first flange is a ring-shaped steel plate, and the fixed steel bars include six ribbed steel bars. The six ribbed steel bars pass through the holes reserved in the ring-shaped steel plate for a certain distance and are welded. The other end of the ribbed steel bars is bent outward; embedded in the groove Flange hooks to ensure its vertical verticality and horizontal position;

[0057] Hoisting, positioning composite piers and pouring notches:

[0058] The...

Abstract

The invention discloses an energy dissipation and vibration reduction corrugated steel tube-rubber concrete assembly type pier and a method. The pier comprises a bearing table, a supporting column anda cover beam which are sequentially connected from bottom to top, the bearing table and the supporting column are in abut joint through a flange, the abut-joint flange is completely poured in a groove of the bearing table, a reinforcement cage framework is arranged in the supporting column, concrete is poured, the top is matched with a hole way preinstalled in the cover beam through longitudinalreinforcements, the cover beam is mounted on the supporting column through cooperation of the hole way and the upper ends of the longitudinal reinforcements, and the cover beam is used for being matched with the supporting column and the bearing table to achieve supporting of an upper bridge structure. Through the assembly design, the construction efficiency of the bridge is improved, the whole vibration reduction capacity is improved, the better construction portability and energy dissipation and vibration reduction capacity are better, in addition, an undulated structure outside the supporting column has the effect of relieving the impact force, the action force of impact to the pier is weakened, and through rubber concrete poured into corrugated steel tubes, needs of the vibration resistance ductility and active energy dissipation capacity of the pier are improved.

Description

technical field [0001] The application relates to the field of bridge engineering, in particular to a corrugated steel pipe-rubber concrete assembled bridge pier for energy consumption and shock absorption and a method thereof. Background technique [0002] At present, the substructure of the bridge mostly adopts reinforced concrete structure, and the construction generally adopts the method of pouring on site. This kind of pouring on site construction requires a lot of labor, erecting brackets and formwork, and is highly dangerous; it also causes noise and waste slag pollution to the surrounding environment. Seriously affect the normal traffic around the city; this construction method has a low level of industrialization, relatively low construction efficiency, and the overall energy consumption of the industry is relatively high. Compared with traditional cast-in-place bridge piers, prefabricated composite bridge piers have the characteristics of fast construction speed, s...
