Description
Technical field
The transformation that the utility model is related to a kind of stone arch bridge is reinforced, more particularly to a kind of stone arch of integral reinforcing transformation main arch
Bridge.
Background technology
For a long time, stone arch bridge is due to excellent with easy construction, convenient material drawing, economy and durability etc. for Chinese Construction of Arch Bridges historical origin
Point, and the highway construction in early stage is generally used, and due to technical conditions and economic limitation, common design standard is relatively low,
Various jumboes in engineering construction frequently can not be born, vehicle passes through.New extension builds builder's road, suspension bridge is almost
The necessary component of each project's earlier stage preparation, its processing scheme to stone old arch bridge is varied, and with newly-built
Based on reinforcing mode, in the prior art, the Scheme of Strengthening of such bridge is concentrated mainly on following several：1. set arch is (i.e.
Internal Lining Method)：The method passes through increase by forming overall structure in the upper (lower) edge linked network of arch ring, implantation reinforcing bar and gunite concrete
The method of main arch ring area of section improves bearing capacity.The advantages of method, is that difficulty of construction is small, required construction equipment also compared with
Simply, and cheap, construction period is also shorter.But difficulty is larger when lower edge is constructed when pouring into a mould concrete, it is likely that exists
During concrete construction, finding concrete, cast is not entered at all.Even if cast is entered, can also exist and combine uncompacted problem.
This be due to general thickening layer all than relatively thin, the concrete pumped into vertical drop under gravity.Reinforcing bar be shaped form,
Template is curved, and the Concrete in Natural of whereabouts is just deposited between reinforcing bar, template.Shocked by plug-in type and adhesion type vibrator
Afterwards, concrete still leakiness, a large amount of concrete are deposited in pouring template mouth.Although upper limb (hogback) cast is not present upper limb and poured into a mould
The problem of, and the area of newly-increased part is from neutral axis farther out, the resistance moment that unit area is provided is bigger, i.e. section high efficiency.
But the latter needs to remove superstructure, long construction period, and budget also increases.Two kinds of construction methods are intended to set up bow member or branch
Frame.2. shorten across footpath method：The method is by setting up template at arch springing, forms battered leg by cast-in-place concrete and is supported on main arch ring
On, improve the bearing capacity of arch bridge so as to share the stress on main arch ring.The method long construction period, and change structure by
Force characteristic, under-clearance is reduced, it is unfavorable for the arch bridge across river, and cost and requirement to construction are also higher.3. more
Change arch bridge superstructure method：The method passes through cored slab by the way that the superstructure filler of arch bridge is removed in arch bridge superstructure
With the cast integral structure of column-type, it is that dead load can be mitigated the advantages of the method, and makes arch ring together with superstructure,
The load from superstructure is born jointly, and shortcoming is that needs suspend traffic and cost is of a relatively high.4. external prestressing is set
Method.The method is usually used in the reinforcing of beam bridge, and the reinforcing to arch bridge is more rare, and the reinforcing method to double curvature arched bridge is mainly logical
Cross and crossbeam is poured into a mould between arch rib, external prestressing is anchored on crossbeam and improves the bearing capacity of arch bridge.This method is reinforced
Effect is preferable, but cost is high, and also high to construction requirement, the time that suspends traffic is also longer.5. counterweight method：Counterweight method reinforces arch bridge one
As be applied to intrinsic pressure line and arch and have certain deviation or bridge pressure line and arch after runing for many years
The situation of deviation.The method applies weight by accurate location that some process calculates on main arch so that arch and pressure line
It coincide as far as possible so as to significantly improve the stress performance of structure.The method short construction period, it is high to construction requirement, and influence bridge
The overall appearance of girder construction.Traditional Cast-in-place concrete or jetting cement increasing section method for strengthening is deposited although more economical and performance is also reliable
The complicated curing time long in time limit of construction is long the defects of, it is difficult to meet on the time, other reinforcement and strengthening methods are as mitigated dead load weight
The methods of amount, arched girder combine is not only long in time limit but also to suspend traffic more infeasible.Traditional ruggedized construction and construction method,
The low cost, high quality, efficient requirement that the development of economic technology required engineering project can not be met, there is an urgent need to one kind
Meet engineering project to cost, efficiency, the requirement of duration.
