According to the concrete prefabricated section assembled pier, the temporary supporting cost during pouring is reduced, and the construction period is shortened.
Description
Technical field
The utility model belongs to civil engineering bridge field, is specifically related to a kind of concrete prefabricated section assembling bridge pier.
Background technology
Precast assembly bridge pier, due to advantages such as its easy construction, duration are short, good endurance, is studied abroad and is applied, and is widely used in Oversea bridge engineering and offshore construction platform.The research of domestic section assembling construction technology is relative less with application, mainly concentrate in bridge superstructure, the nearly more than ten years just start for lower bridge pier structure, and the larger bottom precast construction recently completing is the constructure scheme of section assembling bridge pier as employings such as Donghai Bridge, Hangzhou Gulf Great Bridge, Changjiang River Bridge Shanghais.
From construction angle, bridge pier can be divided into integral cast-in-situ and prefabricated installation.Wherein, integral cast-in-situ bridge pier has good resistance to overturning, but its support cost is very high, the duration is relatively long.Precast Concrete Segmental Bridges bridge pier is by bridge pier vertically, be divided into some parts by certain modulus, builds then on-site consolidation at precasting yard on the ground.In China's Practical Project, section assembling bridge pier at present adopts wet seam to connect, adopt the mode of posttension prestressing with bond that sections is connected into entirety, but, between sections joint face, often can cause rod iron or steel hinge line corrosion owing to contacting leakiness, in addition, also need in preserved pipeline, be in the milk, working procedure complexity.
China is in extensive transport development period, the suitable application area of substructure section assembling construction technology just such as overhead road of city and bridge pier over strait.Therefore, study the assembled bridge pier of a kind of assembled precast concrete segment easy, durable practicality and just seem particularly urgent.
Summary of the invention
The purpose of this utility model is to provide a kind of concrete prefabricated section assembling bridge pier, while solving in prior art monobloc cast concrete pier, temporary supporting cost is high, the construction period long and while adopting wet seam splicing between sections contact closely, easily do not grind one's teeth and the problem such as rod iron easy-to-rust.
The technical solution that realizes the utility model object is: a kind of concrete prefabricated section assembling bridge pier, comprises M the first sections, N the second sections, billet, bolt, presstressed reinforcing steel, anchor block, basis, top board, wherein M >=1, N >=1; One end of presstressed reinforcing steel is anchored in basis, the other end is anchored on the first sections being connected with top board, between basis and top board, be arranged alternately M the first sections and N the second sections, on the first sections inwall, anchor block is set, presstressed reinforcing steel is along the inwall setting of the first sections, and through the through hole of offering in advance in the anchor block on the first sections inwall, be bolted on anchor block, between bolt and anchor block, be provided with billet.
The utility model compared with prior art, its remarkable advantage: mutual socket joint between (1) sections, can form the machine-processed horizontal loads of resisting of effective shearing resistance; (2) by external stretch-draw prestressing force rod iron or steel hinge line, can guarantee to connect closely between sections contact surface, there is good impermeable and durability performance, in reducing rod iron easy-to-rust risk, also facilitate operating personnel's construction and detected; (3) adopt and carry out preservative treatment on presstressed reinforcing steel surface, avoided this working procedure of duct grouting, the phase, assembled speed was fast, effectively the reduction of erection time; (4) meet with after earthquake, the convenient effective prestress size that checks, can mend if desired tension prestress or change rod iron.
Accompanying drawing explanation
Fig. 1 is the intersegmental connection diagram of concrete prefabricated section assembling bridge pier of the present utility model.
Fig. 2 is the A-A sectional drawing of concrete prefabricated sections 1 of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In conjunction with Fig. 1 and Fig. 2, a kind of concrete prefabricated section assembling bridge pier, comprises M the first sections 1, N the second sections 2, billet 3, bolt 4, presstressed reinforcing steel 5, anchor block 7, basis 8, top board 9, wherein M >=1, N >=1; One end of presstressed reinforcing steel 5 is anchored in basis 8, the other end is anchored on the first sections 1 being connected with top board 9, between basis 8 and top board 9, be arranged alternately M the first sections 1 and N the second sections 2, on the first sections 1 inwall, anchor block 7 is set, presstressed reinforcing steel 5 is along the inwall setting of the first sections 1, and through the through hole 10 of offering in advance in the anchor block 7 on the first sections 1 inwall, be fixed on anchor block 7 by bolt 4, between bolt 4 and anchor block 7, be provided with billet 3.
Also comprise connector 6, between adjacent presstressed reinforcing steel 5, connect by connector 6.
On the joint face between the first sections 1, the second sections 2, basis 8 and top board 9, apply epoxy resin.
Presstressed reinforcing steel 5 is prestressed steel bar or prestress wire.
So that being set between basis 8 and top board 9,1 and 3 the second sections 2 of 2 the first sections briefly explain as example, first, should complete at the scene that basic 8 templates are set up, assembling reinforcement and reservedly wear muscle through hole, penetrate afterwards prestress wire 5, water underpin 8 concrete and fixing prestress wire 5, then with lifting machine, second sections 2 is vertically placed on basis 8, on the second sections 2, put again first sections 1, by brushwork epoxy resin to sections with basis, joint face between sections and sections carries out joint treatment, subsequently will be through antiseptic prestress wire 5(external surface brushwork epoxy resin or zinc-plated) aim at through the reserved through hole 10 in anchor block 7, employing jack pair prestress wire 5 carries out stretch-draw and is fixed in the top of anchor block 7, lift by crane successively more afterwards another two second sections 2 and another first sections 1, until each sections lay in place after, interspersed prestress wire 5, adjacent prestress wire 5 connects by connector 6, joint is positioned at the second sections 2, the same jack that adopts is anchored at the presstressed reinforcing steel of upper end 5 in the first sections 1 being connected with top board 9, finally, place a block concrete top board 9 at prefabricated subsection 1 top and carry out encapsulation process, so just each prefabricated subsection closely can be assembled into a common stressed bridge abutment integral.Can guarantee closely to connect between prefabricated subsection by this connected mode, can effectively improve sealing and the durability performance of bridge pier.
