Description
Technical field
The present invention relates to field of bridge deck pavement, in particular to three-dimensional porous plastic material deck installation structure and its construction party
Method.
Background technique
Along with the process that China reforms and opens up to the outside world, highway, city expressway and major urban arterial highway have been obtained rapidly
Development, built large quantities of highway bridge and Urban Bridge.So far, the built all kinds of modernization bridges in China are in world's bridge
Important ranking is all entered in girder span diameter ranking, or even is come out at the top.It from a side reflect China's production, it is economical with
The development height of science and technology.
Along with flourishing for Bridges in Our Country technology, bridge construction technology reaches its maturity, in bridge overall structure
The problem of increasingly reduce.In contrast, bridge is mated formation and is but usually ignored by engineer, and the Bridge Design specification and cement in China are mixed
Solidifying soil surface job specfication also simply shows the thickness requirement of concrete pavement and asphalt pavement, keeps deck paving excessively too early
The case where destruction, is commonplace, and bridge floor is repaired each time, all brings huge pressure to traffic.For example, Chongqing City Flower garden is big
Bridge is the important channel for connecting Yu Zhong district and Jiangbei District, and now average daily vehicle flowrate reaches 140,000, must not since damaging oof bridge surface is serious
Not starting that deck paving has been carried out to handle up to replacement in more than 60 days on 2 25th, 2013, associated vehicle has to detour,
It greatly affected the normal trip of people, also cause huge current pressure to bridge, gather around the city of script congestion more
It is stifled.
Deck paving is the part that wheel directly acts on.The effect of deck paving is to prevent vehicle tyre or crawler belt direct
Carriageway plate is worn away, protects girder from rain erosion, and distribution is served to the load of vehicle wheel weight.This is namely
It says, on the one hand, deck paving must provide a comfortable driving condition to vehicle and spread load, it is necessary to have enough rigid
Degree and good overall performance have the performances such as cracking resistance, antiskid, wear-resisting.On the other hand, bridge is mated formation viscous with bridge force-bearing structure
Knot forms overall work, and bridge is mated formation can be as the loading characteristic of bridge structure may bear pulling force or pressure.
It is one of pavement material most-often used on Short/Medium Span Bridge that portland cement concrete, which is mated formation,.Ordinary cement coagulation
The distinguishing features such as soil material materials are convenient, and reliable performance, rigidity is big, and intensity is high, and sturdy and durable and routine servicing workload is small.It is general
The elasticity modulus of water flowing cement concrete pave-load layer is big, and flexural tensile strength is small, and Brittleness is obvious, and current noise ratio asphalt mixture surfacing is wanted
Greatly, comfort is also inferior compared with asphalt pavement.
Since bituminous concrete overlay has rapid construction and good driving performance, modern bridge is mated formation usually
Using asphalt concrete pavement.But the durability of Asphalt Concrete Deck Pavement but wretched insufficiency.A usual highway
Usually shorter than subgrade and pavement more of the total length of the structures structure such as upper bridge, channel and crossings on different level, but in most of height
The quantity that asphalt concrete pavement on fast highway on structure concrete pavement generates pit-hole is often more than subgrade and pavement
The pit-hole of upper generation, the former repairing rate is often bigger than the repairing rate of the latter more and is easier that track occurs and pushes away to gather around.In addition,
The asphalt concrete pavement of concrete surface layer is also easier to generate rut slot than asphalt concrete pavement on subgrade and pavement.
Therefore, it is necessary to a kind of novel deck installation structures, improve the intensity of deck installation structure, enhance anti-bending strength,
Anti-rut behavior, avoids the generation of fatigue crack, while improving anti-high and low-temp performance, reduces bridge maintenance rate, extends bridge floor paving
The service life of assembling structure, and then improve travel safety.
Summary of the invention
In view of this, three-dimensional porous plastic material deck installation structure of the invention and its construction method, deck paving knot
Structure intensity is high, and anti-bending strength and anti-rut behavior are excellent, while having preferable anti-high and low-temp performance, reduces bridge maintenance rate,
Extend the service life of deck installation structure, and then improves travel safety.
