For achieving the above object, the present invention adopts following technical scheme:
The dark beam slab pavement system of a kind of bridge-type prefabricated reinforced concrete, comprise basis and road slab, described basis is that prefabricated inverted T shape strip foundation, described road slab are the dark beam slab of prefabricated reinforced concrete, and the upper surface of described prefabricated inverted T shape strip foundation and the dark beam slab of prefabricated reinforced concrete all is embedded with four fiber tubes; The upper reinforcement of the end face of described fiber tube and the dark beam slab of prefabricated reinforced concrete is welded to connect, and the dark beam slab frame of described prefabricated reinforced concrete is lined with L type rubber pad on both contact surfaces on the step of prefabricated inverted T shape strip foundation side.
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 inner screw sheath external diameter of pipe is 4cm, and internal diameter is 2cm, highly is 8cm; The diameter of described external screw thread rod iron is 2cm, highly is 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 job practices of the dark beam slab pavement system of described bridge-type prefabricated reinforced concrete, it is characterized in that: step is as follows:
Step 6 at the pre-buried position of inverted T shape strip foundation end face fiber tube dress suspension ring, winches to the installation site with the inverted T shape strip foundation, lays down suspension ring;
Step 7 is at the pad L of the step place of prefabricated inverted T shape strip foundation type rubber pad;
Step 8 adopts the mode identical with lifting the inverted T shape strip foundation that the dark beam slab of steel concrete is winched to the installation site, and is erected at T type strip foundation step place, and holds out against with the edge of a wing and the web of T type strip foundation.
Compared with prior art the present invention has following characteristics and beneficial effect:
Advantages such as the dark beam slab pavement system of bridge-type prefabricated reinforced concrete of the present invention is compared with traditional road pavement and method for maintaining, has the structural strength height, is convenient to transportation, and is reusable, and it is efficient to construct are in particular in the following aspects:
1) convenient transportation.Though structure is built by steel concrete, the volume of each piece is little, and is standardized structural element, transports more convenient.
2) Fast Installation, easy construction.Structure top is provided with built-in fitting, makes that installing and the removal of the dark beam slab pavement system lifting of bridge-type prefabricated reinforced concrete suspension ring are very convenient, and then makes that the lifting of the dark beam slab pavement system of this bridge-type prefabricated reinforced concrete is very convenient.In when construction, earlier reinforced concrete strip foundation is lifted smooth road surface, the darker beam slab of steel concrete is lifted on the strip foundation, after splicing is finished, without any need for being connected, can use between between piece and the piece and piece and the basis.
3) the required plant equipment of construction is few, and material usage is economized, and low its of energy consumption can be reused, and reduces construction costs and other expense greatly.Be prefabricated in the factory because adorning prefabricated reinforced concrete strip foundation and the dark beam slab of prefabricated reinforced concrete, at the construction field (site), only need grading, lifting is laid the dark beam slab pavement system of this bridge-type prefabricated reinforced concrete and is got final product, to temporary road, it is recyclable to use up the back, in order to using next time, further saves material usage.
4) pavement construction is few to ambient influnence.Traditional pavement construction needs more construction machinery, produces bigger noise during the construction machinery operation.Simultaneously, waste material of buildings is more in traditional pavement engineering construction, comprises water conservancy, timber, packaging material, discarded mould etc.These refuses are buried under the ground, and can cause phreatic pollution.The present invention is prefabricated at the workshop, and refuse is less and can focus on, to the almost not influence of job site environment.
5) namely spread i.e. usefulness, open to traffic early.In case laying construction finishes, just open to traffic immediately behind the removal suspension ring.Even can be open to traffic while constructing, be conducive to conveniently marching into the arena of construction machinery and Construction traffic, accelerating construction progress.The time that is open to traffic behind the construction of cement concrete road surface, the time that is open to traffic behind the asphalt concrete pavement construction, the dark beam slab pavement system of bridge-type prefabricated reinforced concrete of the present invention can namely be spread i.e. usefulness greater than 3 days greater than 16 days, even the shop, limit is just used.
6) dismounting freely.The dark beam slab pavement system of bridge-type prefabricated reinforced concrete is reusable, can lay in advance, is transported to on-the-spot the laying when to be needed and gets final product.Built-in fitting is housed in the structure, installs, the removal suspension ring are very convenient, structure hoisting fashionable dress upper lift ring can lift.
7)Technology is simple, and cost is lower, and the dark beam slab pavement system of bridge-type prefabricated reinforced concrete adopts ordinary reinforced concrete as the preparation 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 that is damaged in the earthquake.
8) by being lined with L type rubber pad at the dark beam slab of prefabricated reinforced concrete and prefabricated inverted T shape strip foundation contact surface, submit the vibration damping and vibration isolation effect of bridge to, improve the application life of bridge.
