Beneficial effect of the present invention is as follows:
System main body of the present invention is prefabricated reinforced concrete strip foundation and combining structure road surface.Prefabricated reinforced concrete strip foundation and combining structure road surface are separated by rubber pad.Prefabricated reinforced concrete strip foundation inside arranges reinforcing bar.Prefabricated reinforced concrete strip foundation upper surface is equipped with pre-buried fiber tube one, so as with lifting.Prefabricated reinforced concrete strip foundation end is also provided with pre-buried fiber tube two, can connection side to limiting plate, with limit combination structural pavements lateral displacement.Pre-buried fiber tube top is a sleeve pipe with screw thread, and bottom is a rod iron, and Socket welding is connected on rod iron.In order to strengthen the anchoring strength of pre-buried fiber tube and structure, bottom rod iron, be welded with steel plate.During lifting, screwed suspension ring are screwed into sleeve pipe, again by suspension ring removal after having lifted.
During the unit processing and fabricating of combining structure road surface on girder web plate hole, welding node plate, utilize high-strength bolt that girder is connected.Road surface girder comprises longitudinal edge girder, longitudinally middle girder and widthwise edge girder.Welding node plate is adopted between girder, and by the mode that junction plate is connected with high-strength bolt.Steel plate and girder utilize and are uninterruptedly welded into entirety.Combining structure road surface is provided with shear stud, can make armored concrete slab and steel plate co-operation.Combining structure road surface is also provided with pre-buried fiber tube three, so that lifting.The stabilized structure of combining structure road surface unit, connects reliable, is convenient to installation and removal.
In order to make bridge-type combining structure road slab interblock laterally connect reliably, perforate on longitudinal end of main beam web, weldable steel sleeve, penetrates drawing anchor bolts.
Bridge-type combining structure pavement system of the present invention, lays with traditional road and compared with method for maintaining, has structural strength high, and be convenient to transport, reusable, the advantages such as high construction efficiency, are in particular in the following aspects:
1, convenient transportation.The volume on each block combining structure road surface is little, and is standardized structural element.
2, Fast Installation, easy construction.Prefabricated strip foundation and combining structure road surface are equipped with lifting hole(eyelet), convenient lifting.After hoisted in position, penetrating drawing crab-bolt and fixed connecting plate, can use.
3, the required plant equipment of construction is few, and material usage is economized, and can reuse, and greatly reduces construction costs and other expenditure.Because prefabricated reinforced concrete strip foundation and combining structure road surface are prefabricated in the factory and process, at the construction field (site) only need by grading, combining structure pavement system is laid in lifting.For temporary road, be finished rear recyclable, use in order to next time, save material usage further.
4, pavement construction is few to ambient influnence.Traditional pavement construction needs more construction machinery, produces larger noise when construction machinery runs.Meanwhile, in traditional pavement engineering construction, waste material of buildings is more, comprises water conservancy, timber, packaging material, discarded mould etc.These refuses are buried under the ground, and can cause the pollution to underground water.The present invention is prefabricated at workshop, and refuse is less and can focus on, and does not almost affect job site environment.
5, namely spread i.e. use, open to traffic early.Once laying construction is complete, just can open to traffic immediately after removal suspension ring.Even can be open to traffic on construction limit, limit, be conducive to conveniently marching into the arena of construction machinery and Construction traffic, accelerating construction progress.The time that is open to traffic after construction of cement concrete road surface is greater than 16 days, and the time that is open to traffic after asphalt concrete pavement construction is greater than 3 days, and namely bridge-type combining structure pavement system of the present invention can spread i.e. use, and even Bian Pu limit is used.
6, dismounting freely.Bridge-type combining structure pavement system is reusable, can lay in advance, and the scene that is transported to when needed is laid.In structure, built-in fitting is housed, installs, removal suspension ring are very convenient, structure hoisting fashionable dress upper lift ring and Liftable.
7, applied widely.Bridge-type combining structure pavement system is applicable to the various roadbeds with certain bearing capacity, is mainly used in quick laying construction transport channel, ensures the current smoothly of construction vehicle.The present invention can not only be used in the laying of construction with interim matter transportation road, can also be used for rushing to repair the road be damaged in earthquake.
