Described fiber tube is made up of internal thread sleeve pipe, external screw thread rod iron, rectangle anchor slab and bar dowel, described external screw thread rod iron is vertically welded in rectangle anchor slab center, described internal thread sleeve pipe and external screw thread rod iron are threaded, described bar dowel is symmetrically welded at external screw thread rod iron both sides near rectangle anchor slab marginal position, and rectangle anchor slab edge is all exposed at its two ends.
Described internal thread sleeve outer is 4cm, and internal diameter is 2cm, is highly 8cm; The diameter of described external screw thread rod iron is 2cm, is highly 8cm; The length of described rectangle anchor slab is 15cm, and width is 10cm, and thickness is 1cm; The diameter of described bar dowel is 1cm.
The soffit of the dark beam slab of described prefabricated reinforced concrete is embedded with suspension ring, and the lower rebar of described suspension ring and the dark beam slab of prefabricated reinforced concrete is welded to connect.
The length of described prefabricated inverted T shape strip foundation is 4m, and flange width is 1m, and edge of a wing thickness is 0.3m, web width 0.5m, web height 0.35m.
The length of the dark beam slab of described prefabricated reinforced concrete is 3m, and width is 1m, and thickness is 0.3m.
The construction method of the described dark beam slab pavement system of bridge-type prefabricated reinforced concrete, is characterized in that: step is as follows:
Step one, prefabricated inverted T shape strip foundation;
Step 2, the dark beam slab of prefabricated reinforced concrete; Prefabrication process is: the reinforcing bar of the dark beam slab of colligation prefabricated reinforced concrete, and preset fiber tube at its soffit, and the upper reinforcement of described fiber tube top and the dark beam slab of prefabricated reinforced concrete being welded to connect, then concreting carry out maintenance, and surface programming suspension ring thereon;
Step 3, after the dark beam slab of steel concrete is shaping, catches on suspension ring by crane gear, and sling by dark for steel concrete beam slab, then suspension ring are cut off by the demoulding, and dark for steel concrete beam slab upset is made facing up of band built-in fitting;
Step 4, is removed road surface, is flattened by road by machinery;
Step 5, is transported to job site by prefabricated inverted T shape strip foundation and the dark beam slab of steel concrete;
Step 6, at inverted T shape strip foundation end face fiber tube pre-buried position dress suspension ring, winches to installation site by inverted T shape strip foundation, lays down suspension ring;
Step 7, at the step place pad L-type rubber pad of prefabricated inverted T shape strip foundation;
Step 8, adopts the mode identical with lifting inverted T shape strip foundation that dark for steel concrete beam slab is winched to installation site, and is erected at T-shaped strip foundation step place, and holds out against with the edge of a wing of T-shaped strip foundation and web.
Compared with prior art the present invention has following characteristics and beneficial effect:
The dark beam slab pavement system of bridge-type prefabricated reinforced concrete 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.Although structure is built by steel concrete, the volume of each block is little, and is standardized structural element, transports more convenient.
2) Fast Installation, easy construction.Structure upper is provided with built-in fitting, make the installing of bridge-type prefabricated reinforced concrete dark beam slab pavement system hoisting ring and removal very convenient, and then make the lifting of the dark beam slab pavement system of this bridge-type prefabricated reinforced concrete very convenient.When constructing, first reinforced concrete strip foundation being lifted into smooth road surface, darker for steel concrete beam slab is lifted in strip foundation, after having spliced, without any need for being connected between block with block and between block with basis, can use.
3) the required plant equipment of construction is few, and material usage is economized, and low its of energy consumption can be reused, and greatly reduces construction costs and other expenditure.Because dress prefabricated reinforced concrete strip foundation and the dark beam slab of prefabricated reinforced concrete are prefabricated in the factory, at the construction field (site), only need by grading, the dark beam slab pavement system of this bridge-type prefabricated reinforced concrete is laid in lifting, to 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 of 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 the dark beam slab pavement system of bridge-type prefabricated reinforced concrete of the present invention can spread i.e. use, and even limit paving is just used.
6) dismounting freely.The dark beam slab pavement system of bridge-type prefabricated reinforced concrete 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)technique is simple, and cost is lower, and the dark beam slab pavement system of bridge-type prefabricated reinforced concrete adopts ordinary reinforced concrete as preparing material, and the cost of material is low, and structure is unified standard size, Mold Making and build all very convenient.Applied widely.The dark beam slab pavement system of bridge-type prefabricated reinforced concrete is applicable to the various roadbeds with certain bearing capacity, 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.
8) by being lined with L-type rubber pad on the dark beam slab of prefabricated reinforced concrete and prefabricated inverted T shape strip foundation contact surface, submitting the vibration damping and vibration isolation effect of bridge to, improving the application life of bridge.
