Abstract
The utility model provides a prefabricated cement concrete pavement of assembling, it links together through prestressed anchorage spare and prestressed cable and constitutes the cement concrete road surface including prefabricated cement concrete board, prestressed anchorage spare, prestressed cable and grout hole, prefabricated cement concrete board. The utility model provides a prefabricated cement concrete pavement of assembling's superiority lie in that its inter -plate passes lotus ability and provides by the prestressed cable, cable wire itself prestretch the stress stability of lifting plate piece by a wide margin, has effectively avoided simultaneously and has watered the nondeterminacy that the concrete brought behind the seam crossing, carry on one's shoulder or back efficiency with the biography that effectively guarantee prefabricated cement concrete pavement of assembling.
Description
Technical field
The utility model belongs to highway construction technical field, is specifically related to a kind of precast assembly cement concrete pavement.
Background technology
Green concrete is cast in above basic unit by Portland cement concrete pavement, through the health of 28 days, even longer time, can form intensity, then for being open to traffic.For the road surface having the time requirement that is open to traffic; Portland cement concrete pavement can not meet the requirement of its time window; for speedway maintenance works; reduce maintenance time and can alleviate the section caused due to close traffic as far as possible and block, significant to the property life security of the protection people.
Precast assembly cement concrete pavement is built in advance by road surface plate, is transported to scene, fits together according to certain rule, can ensure the requirement that is open to traffic fast on road surface, significant for the road surface and maintenance works having the time requirement that is open to traffic.
At present, the connection between precast assembly cement concrete pavement prefabricated chunk realizes mainly through dowel bar, needs the reserved passageway when plate is prefabricated in advance, is placed to after design attitude, dowel bar is put into passage until plate, then concreting.Therefore, interplate Load-transfer Capacity depends on dowel bar quality and length, the quality of after-pouring concrete material and the adhesion strength of concrete and prefabricated chunk, that is: between the road slab connected by dowel bar, load transfer efficiency is by the impact of many factors, and reliability is poor, and load transfer efficiency is lower.
Summary of the invention
The utility model, for this problem, proposes a kind of precast assembly cement concrete pavement, it solves the problems referred to above.
The technical scheme that the utility model adopts is as follows:
A kind of precast assembly cement concrete pavement, it comprises pre-cast concrete concrete slab, prestressing force anchor, prestressed cable and grout hole, and pre-cast concrete concrete slab to be linked together formation cement concrete pavement by prestressing force anchor and prestressed cable.
Pre-cast concrete concrete slab wherein while be provided with rectangular preiection, parallel is other while be provided with rectangular recess, rectangular preiection and rectangular recess can together with interlockings, orthogonal while be reserved with prestressed pore passage, can link together by prestressing force anchor and prestressed cable, form road structure, the grout hole of reserved adjustment panel space position of can being in the milk after mounting on plate.
Compared with prior art, the utility model has the advantage of:
The superiority of the precast assembly cement concrete pavement that the utility model provides is, between its plate, Load-transfer Capacity provides by prestressed cable, the pre-tensile stress of cable wire itself will significantly promote the stability of plate, the uncertainty that after effectively having avoided seam crossing, pouring concrete brings simultaneously, will effectively ensure the load transfer efficiency of precast assembly cement concrete pavement.
Accompanying drawing explanation
Fig. 1 is the lateral connection figure of a kind of precast assembly cement concrete pavement of the utility model;
Fig. 2 is longitudinal connection layout of a kind of precast assembly of the utility model cement concrete pavement;
Fig. 3 is prestressing force anchor and the prestressed cable connection diagram of a kind of precast assembly cement concrete pavement of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of precast assembly cement concrete pavement, as Figure 1-3, it comprises pre-cast concrete concrete slab 1, prestressing force anchor 2, prestressed cable 3 and grout hole 4, and pre-cast concrete concrete slab 1 to be linked together formation cement concrete pavement by prestressing force anchor 2 and prestressed cable 3.
Pre-cast concrete concrete slab 1 wherein while be provided with rectangular preiection, parallel is other while be provided with rectangular recess, rectangular preiection and rectangular recess can together with interlockings, orthogonal while be reserved with prestressed pore passage, can link together by prestressing force anchor 2 and prestressed cable 3, form road structure, the grout hole 4 of reserved adjustment panel space position of can being in the milk after mounting on plate.
Embodiment:
Need whole plate to change cement concrete plate 4 pieces in certain speedway maintenance works, utilize the road structure that the utility model relates to, detailed description of the invention is as follows:
A kind of precast assembly cement concrete pavement, comprises pre-cast concrete concrete slab (1), prestressing force anchor (2) and prestressed cable (3).Pre-cast concrete concrete slab (1) to be linked together formation cement concrete pavement by prestressing force anchor (2) and prestressed cable (3), reserved grout hole (4) on plate, adjustment panel space position of can being in the milk after mounting.
The cement concrete slab of first prefabricated 4 pieces of 2m × 3m × 26cm, the prestress application hole of 20cm × 60cm is reserved every 60cm in side, long limit, correspondence position reserves prestressed pore passage, channel diameter is 1.5cm, panel sides is extended through from prestress application hole, the one-sided of short side direction two boards is arranged to 8cm × 8cm × 5cm rectangular recess, and the side of two boards arranges the rectangular preiection of 7.5cm × 7.5cm × 4.5cm in addition, need configure corner bar when wherein corner areas is built.
After underseal work completes, 4 pieces of precast plates are transported to scene, and short side direction convex-concave connects, and long side direction wears presstressed reinforcing steel in prestressed pore passage, and uses prestressing force anchor that adjacent two boards is tentatively fixing.Finally in the grouting of grout hole place, plate locus is met requirement is set, prestressing force anchor is being fixed further.After 4-5 hour fast health-promotion, can be open to traffic.
Above-mentioned detailed description of the invention is a preferred embodiment of the present utility model; be not for limiting enforcement of the present utility model and right; all equivalences made according to the content described in the utility model patent protection scope change and modify, and all should be included in the utility model patent claim.
