Description
Technical field
The present invention relates to technical field of bridge construction, especially a kind of prefabricated assembled suspension bridge bridge pier.
Background technique
In bridges in highway engineering work progress, the top priority that builder's road is the construction stage is built, sidewalk uses
Also extend through all stage in construction.In sidewalk work progress, across river at need to set up make-shift bridge, make-shift bridge
Setting up speed is the key that entire sidewalk construction speed.It is also a key factor for influencing entire project construction progress.
Traditional make-shift bridge bridge pier generallys use cast-in-situ steel reinforced concrete, and the method has the following problems: first is that when construction
It needs to build island cofferdam, accumulates a large amount of sandstone and other materials, removed after to be onstructed, expend a large amount of manpower and material resources,
And river is caused to block, it is very fast or water larger area is difficult to realize in flow velocity；Second is that foundation pit needs to drain before bridge pier pours,
But if river water head is larger, and water electrode easily enters from the sand material gap in loose cofferdam, causes draining difficulty big, and easily induce pipe
The safety accidents such as gush, topple over；Third is that being not thorough for draining causes river water to penetrate into foundation pit, when concrete is not pre-hardening to concrete table
Face generates impact, and bridge pier cannot be guaranteed at pier quality；Fourth is that the mountable floor system of ability after concrete reaches design strength,
Leverage suspension bridge construction speed；Fifth is that this construction method expends a large amount of manpower and material resources and mechanical, cost increase；Sixth is that work
After completion of works, bridge pier is removed difficult, also becomes waste material a pile after dismounting, cannot reuse, for 10m or so only have one across
Suspension bridge applicability is poor.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
A kind of prefabricated assembled suspension bridge bridge pier, as shown in Fig. 1 ~ 3, comprising: the multiple basic units 100 being stacked up, often
One basic unit 100 includes two prefabricated sections 2, each prefabricated section 2 is rectangular shape, and is had parallel, planar
Upper and lower surfaces, one end of prefabricated section 1 is provided with the step 101 of rectangular shape, the height of step 101 is that prefabricated section 1 is thick
The half of degree, two prefabricated sections 1 form the basic unit 100 with the consistency of thickness of prefabricated section 1 by the mutually overlap joint of step 101.
In one optional embodiment of the present embodiment, to guarantee that two blocks of prefabricated sections 1 connect secured in basic unit 100
Property, (position of center line P in Fig. 1) is provided at least one perforation prefabricated section 1 between the outer edge and inward flange of step 101
First mounting hole 102(Fig. 2), after two prefabricated sections 1 are by step 101 mutually overlap joint, two the first mounting holes 102 are vertical
Direction position is corresponding.Multiple 100 heap poststacks of basic unit form the first hole 200(and see Fig. 3), it is set in the first hole 200
It is equipped with the first rod piece 300 to match with its shape.It is by the first rod piece 300 that two in a basic unit 100 are prefabricated
Block is connected as one, meanwhile, and be an entirety by multiple basic units 100 concatenation, it ensure that the fastness and stabilization of bridge pier
Property.The cross-sectional shape of first mounting hole 102 can be round, rectangle and other polygons, preferably justify in the present embodiment
Shape facilitates manufacture.For example, the hollow circular-tube that a nominal diameter is 200mm is arranged in mold, by the open circles when prefabricated
Pipe build-in is in prefabricated section 1, and after the completion of manufacture, the inner cavity of the hollow circular-tube is the first mounting hole 102.Multiple first mounting holes
102 are formed by the first hole 200 as cylinder, and correspondingly, it is 170mm that the first rod piece 300, which can select nominal diameter,
Hollow circular-tube can concrete perfusion in cavity for the intensity for guaranteeing the first rod piece 300.In addition, in present embodiment,
The position of center line P is only provided with first mounting hole 102, can also be as needed, along the direction of center line P setting multiple the
One mounting hole 102.
In the above-described embodiment, prefabricated at each to further strengthen the fastness between multiple basic units 100
