At present, the bridge construction is mainly based on cast-in-place concrete, and the cast-in-place construction of the concrete has the disadvantages of large quantity of required field labor force and high casualty risk; the working procedures are multiple, and the waste of site resources is much; with the reduction of the Chinese population dividend in the last decade, the population aging is serious, and the labor cost is increased; environmental pollution, noise pollution and other adverse social and economic influences in field construction.
The economic quantity is rapidly increased, the site is limited, and the urban construction and operation face huge traffic pressure, so that the construction of three-dimensional traffic is imperative, but the construction of the conventional cast-in-place structure is long in time consumption, traffic jam around the urban construction site is serious in environmental pollution, and the construction method can not adapt to urban development more and more. The novel prefabricated structure can be used for greatly improving the construction efficiency.
Compared with the conventional cast-in-place concrete structure, the hollow pier has the advantages that the moment of inertia is obviously increased, the bending resistance is increased, the dead weight is obviously reduced, and the construction cost, the transportation cost and the hoisting cost are saved under the condition of the same mass. At present, the joint connection mode of the prefabricated pier mainly comprises sleeve steel bar connection, grouting corrugated pipe connection, cast-in-place wet joint connection and conventional socket joint type connection. The sleeve steel bar connection and grouting corrugated pipe connection construction difficulty is large, the sleeve steel bar connection and grouting corrugated pipe connection construction method is generally only used in regions with seismic fortification intensity below 7 degrees, and a connection mode of a prefabrication assembly technology adopted in a high-intensity region needs to be further developed. The work load of the connection of the cast-in-place wet joint and the cast-in-place is large, and the improvement of the construction speed is limited. The stress performance of the joint of the conventional socket joint type connection prefabricated pier stud and the foundation is undefined, the connection is weak, and the thickness of a required bearing platform is large. The invention aims at the problems of a prefabricated bridge, and discloses a socket type prefabricated reinforced concrete hollow pier connecting structure and a manufacturing method.

The grouting sleeve is high in precision requirement, not beneficial to construction and not easy to guarantee quality. The socket splicing between the hollow pier stud and the bearing platform has the advantages of reliable connection, quick construction of the prefabricated pier, easy construction and controllable quality. From the mechanical point of view, the bearing capacity is basically the same as that of a cast-in-place structure, the stress is reasonable, and the bending resistance and torsion resistance are excellent. From the technical implementation perspective, this type of structure is easily prefabricated at the mill, saves the labour, and the quality is easily guaranteed, can save the cost simultaneously at the reasonable scope of distance to transport. And in the field implementation stage, the structure is convenient to splice on the field, has a self-locking function and is easy to accurately position. The pouring of the UHPC is convenient, the strength and the durability meet the requirements, and particularly, under the action of fatigue load, the UHPC can effectively reduce the development of tiny cracks at the crack pouring position.
The technical scheme for solving the technical problems is as follows:

And (3) extending anchoring steel bars 10 in the prefabricated bearing platform, anchoring the lower part of the prefabricated bearing platform in the prefabricated bearing platform (component I), inserting the upper part of the prefabricated bearing platform into the prefabricated hollow pier stud (component II) through a steel plate hole 7 at the bottom of the prefabricated hollow pier stud (component II), and embedding the upper part of the extending anchoring steel bars 10 in the prefabricated bearing platform (component I) in the cast-in-situ core filling concrete 2. And the pier lower steel plate 8 of the prefabricated hollow pier column (component II) is connected with the prefabricated hollow pier column (component II) through an anchoring steel bar (not shown). The bottom of the prefabricated hollow pier column (component II) is connected with the prefabricated bearing platform (component I) through a mortar UHPC9, the side surface of the prefabricated hollow pier column (component II) is aligned and self-locked with the bearing platform steel wedge 4 through the pier column and a crack pouring UHPC6, and the hollow part of the prefabricated hollow pier column (component II) is connected with the prefabricated bearing platform (component I) through the anchoring steel bar 10 extending out of the prefabricated bearing platform and the cast-in-situ core filling concrete 2.
The first component is a prefabricated bearing platform, a socket space and a socket position are reserved before pouring, the interface corrugation 3 is considered to be arranged, the effect of a shear key is achieved, the shear force is effectively transmitted, the interface connection performance of concrete and UHPC is improved, and meanwhile, the phenomenon that the UHPC generates debonding due to repeated action of load when the structure is in a normal use state can be reduced.
The lower end of an anchoring steel bar 10 extending out of the prefabricated bearing platform is anchored in the prefabricated bearing platform concrete, the end part of the lower end of the anchoring steel bar is welded with the prefabricated bearing platform steel bar, and when the prefabricated hollow pier stud is inserted, the anchoring steel bar can extend out of a long round hole of a steel plate at the lower part of the prefabricated hollow pier stud, enters the hollow part of the prefabricated hollow pier stud and then is bent.
And the second component is a prefabricated hollow pier column, a steel plate 8 at the lower part of the pier is positioned at the end part of the hollow pier to seal the hollow pier, but the surface of the second component is provided with steel plate holes 7 to facilitate the extension of anchoring steel bars 10, and then the second component is bent to play a role in locally reinforcing and separating the cast-in-situ C40 core filling concrete 2 and the grout UHPC 9.

When the prefabricated hollow pier stud (the second component) is used for rotationally positioning the steel wedge 4, a certain space is required for the steel plate hole 7 at the lower part of the pier stud corresponding to the anchoring steel bar 10, so that the steel plate hole 7 is arranged to be a long round hole, and the rotation angle of the pier stud can be provided.
In order to improve the connection performance of the hollow pier stud and the prefabricated bearing platform, UHPC mortar is adopted for the bottom of the hollow pier stud and the prefabricated bearing platform, and the compact mark during construction is that UHPC slurry flows out from a steel plate hole 7 at the lower part of the hollow pier stud.
When the prefabricated bearing platform (the first component) and the prefabricated hollow pier stud (the second component) rotate to the position, and after the prefabricated bearing platform and the prefabricated hollow pier stud (the second component) are installed, pouring is carried out by using the pouring UHPC6, so that the structure is integrated. The pouring adopts a one-point pouring and self-leveling mode, so that the compactness can be ensured, and auxiliary vibration measures are not needed.
And finally, in order to meet the anti-collision requirement of the pier stud and provide enough anchoring space for the anchoring reinforcing steel bar 10, the core filling concrete 2 is cast in the hollow position of the hollow pier in situ.
