Description
Technical field
The present invention relates to technical field of bridge engineering, and in particular to a kind of assembled bridge pier and its construction method.
Background technique
Stem grafting stitch section assembling bridge pier because have rapid construction advantage and self-resetting capability, include port Zhuhai and Macao bridge with
Engineer application has been obtained in some across river bridge spanning the seas including Canadian Federal bridge.The bridge pier of this form is by pier shaft edge
Several segments are vertically divided into, Reinforcement disconnects at segmental joints, it is connected between segment using " stem grafting seam ", or
Epoxy resin is filled to improve the durability of bridge pier in seam crossing, is then connected into segment by the way of post-tensioned prestressing whole
Body.Domestic and foreign scholars by experimental and theoretical study find, stem grafting stitch section assembling bridge pier under seismic stimulation energy dissipation capacity compared with
Difference, and be easy to crush in coxopodite section.To improve the energy dissipation capacity that stem grafting stitches section assembling bridge pier, at present in engineering practice
It is the built-in energy consumption reinforcing bar in stem grafting seam section assembling bridge pier with method most commonly used in scientific research, energy consumption reinforcing bar is for ground
It when shake excitation, consumes energy to the shearing force between the seam of segment, but earthquake, when occurring, the energy of generation is multiple sides
To, it is still obvious in the axial direction of bridge pier, existing energy consumption reinforcing bar be poured simultaneously with each segment, therefore consume energy steel
Muscle in the axial direction of bridge pier be it is fixed, without telescopic space, axial energy dissipation capacity is poor, substantially without any energy consumption
Effect, or even say in the excitation by earthquake axial direction, energy consumption reinforcing bar is possible to because of being fixedly connected between segment, can be right
Segmented interior carries out an irreversible execution, and replacement is difficult.If increasing remaining energy-consuming device will increase bridge pier
Manufacturing cost can also generate bigger influence to its structure, lose more than gain.
Summary of the invention
In view of this, energy consumption can be improved the purpose of the present invention is to provide a kind of assembled bridge pier and its construction method

Body pours.
Further, energy consumption reinforced hole, the inner wall of the energy consumption reinforcing bar and the reinforced hole that consumes energy are offered in the segment ontology
Radial direction is separated by form gap.
Further, the upper and lower ends of the segment ontology offer the energy consumption reinforced hole, the energy consumption reinforced hole at both ends
On same axis and the axis passes through the cast-in-place portion, the energy consumption reinforced hole on the segment respectively with adjacent segments section
Energy consumption reinforced hole in the same end matches.
Further, in the segment ontology built-in pipe road to form the energy consumption reinforced hole.
Further, the pipeline, which is located at the nozzle of its lateral ends, is provided with ring washer.
Further, the both ends inner wall of the pipeline is radially inwardly projecting, forms the when progress for installing the ring washer
The step of positioning is provided with the centre bore passed through for the energy consumption reinforcing bar in the middle part of the ring washer, the ring washer
When one side end face is positioned by the step, the end face of another side end face and pipeline.
Further, the pipeline is made up of plastic material, including the first section of jurisdiction and the second section of jurisdiction, first section of jurisdiction and
Second section of jurisdiction is symmetrically arranged semicircle arcs, so that the first section of jurisdiction and the second section of jurisdiction work in coordination to form the complete pipe
Road, first section of jurisdiction and the second section of jurisdiction are mutually permanently connected by the ring washer.
Further, described to be in charge of piece respectively along pipe if first section of jurisdiction and the second section of jurisdiction are in charge of piece by dry plate and are formed
The length direction in road is arranged to form first section of jurisdiction and the second section of jurisdiction.
Further, the energy consumption reinforcing bar is at least two, and is uniformly distributed along the circumferential direction of the bridge pier ontology.
The construction method of assembled bridge pier, using assembled bridge pier described in any of the above embodiments, first by each segment in work
Factory is pre-formed, and first segment is fixedly mounted on cushion cap, then successively up assembled each segment, makes between each segment
Energy consumption reinforced hole on the same line and fixed each segment, whole energy consumption reinforcing bar is passed through to the consumption of all segments
Energy reinforced hole, by pouring the cast-in-place portion on each segment ontology for the energy consumption reinforcing bar respectively at the segment sheet with each segment
Body is fixedly connected, so that the energy consumption reinforcing bar is axially that interruption is discontinuous with the mode that is fixedly connected of bridge pier ontology.
Beneficial effects of the present invention: bridge pier of the present invention, if energy consumption reinforcing bar sequentially passed through along the axial direction of bridge pier ontology it is described
Dry segment, the energy consumption reinforcing bar is connect respectively with described this body space of segment and cast-in-place portion's formed by integrally casting with segment, thus consumes
Can steel-bar arrangement in bridge pier be fixedly connected section be it is intermittent, it is two neighboring to be fixedly connected between section as free segment, therefore can
To improve the scalable amount of energy consumption reinforcing bar in the axial direction, and this energy consumption reinforcing bar is also interruption in the fixed form of bridge pier axial direction
, the both ends of each free segment pass through the cast-in-place portion on the ontology of segment and fix, therefore nor affect on energy consumption reinforcing bar radially
