Meanwhile, the invention further discloses a construction method employing the structure. The method is good on construction safety and short in construction cycle.
Description
Technical field
The present invention relates to a kind of underpasses structure and construction method.
Background technology
Box structure and U groove structure are secretly buried in underpasses many employings in city, are monolithic reinforced concrete structure, adopt constructure scheme to have cut and cover method, shallow burial hidden digging etc.
Shortcoming: (1) site concrete long construction period; (2) cut and cover method needs close traffic, greatly affects road traffic in construction period; Adverse effect is caused to the trip of the people; (3) shallow burial hidden digging, difficulty of construction is large, has risk road surface occurring and collapses.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of underpasses structure, and this structure is applicable to cut and cover method, the low and short construction period of difficulty of construction.
Corresponding to it, another technical problem that will solve of the present invention is the method that application said structure carries out underpasses construction.
With regard to underpasses structure, comprise the precast concrete base being positioned at foundation ditch, the prefabricated steel pipe be positioned on base, the carriageway plate being positioned at prefabricated steel pipe, pit backfill and be positioned at the road surface, upper strata of pit backfill upper surface.
Further, described precast concrete base has deep-slotted chip breaker, described prefabricated steel pipe is positioned at deep-slotted chip breaker.
Further, described carriageway plate comprises the riser of transverse slat and transverse slat bottom, and the two ends, left and right of described transverse slat are connected with pre-manufactured steel tube passage, and the bottom of described riser is connected with the bottom of pre-manufactured steel tube passage.
Further, in described prefabricated steel pipe, between two ends, transverse slat left and right and riser, be provided with arc-like rows water pipe, the top of described arc-like rows water pipe is communicated with transverse slat.
These underpasses structure is applicable to the cut and cover method of underpasses, just can first precast base and steel pipe before foundation ditch is complete, direct mounting seat and steel pipe after foundation ditch completes, without the need to cast in situs component, substantially reduce construction period, the pedestrian in minimizing road pavement and the traffic impact of vehicle.
With regard to underpasses construction method, comprise the steps: S1) precast concrete base and steel pipe;
S2) after excavation pit sclerosis ground;
S3) concrete bed is installed, prefabricated steel pipe is installed immediately as underpass primary structure thing, then build carriageway plate and backfill foundation ditch in pipe, finally pour into a mould road surface, upper strata.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1: the underpasses structure of the present embodiment, the precast concrete base 1 being positioned at foundation ditch, the prefabricated steel pipe 2 be positioned on base, the carriageway plate 3 being positioned at prefabricated steel pipe, pit backfill layer 4 is comprised and the road surface, upper strata 5 that is positioned on pit backfill layer.Concrete bed 1 and prefabricated steel pipe 2 are prefabricated component, can before underpasses construction or the foundation ditch of underpasses complete before make complete, during construction, adopt cut and cover method, after the foundation pit construction of underpasses completes, directly concrete bed 1 and steel pipe 2 are installed, without the need to as existing cut and cover method, cast in situs component after foundation ditch completes, provides the speed of application of cut and cover tunneling, decreases the adverse effect caused the trip of the people.
Concrete, precast concrete base 1 has deep-slotted chip breaker 11, and prefabricated steel pipe 2 is positioned at deep-slotted chip breaker 11, and supported by deep-slotted chip breaker 11 pairs of steel pipes 12, support effect is good.
As the further improvement of technique scheme, described carriageway plate 3 comprises transverse slat 31 and is positioned at the riser 32 of transverse slat bottom, the two ends, left and right of described transverse slat 31 are connected with pre-manufactured steel tube passage, the bottom of described riser 32 is connected with the bottom of prefabricated steel pipe, transverse slat 31 to form two leg-of-mutton supports between riser 32 and corresponding steel pipe 2, structural strength is high, more stable to the support of transverse slat 31 to driving.
As the further improvement of technique scheme, in described prefabricated steel pipe 2, between transverse slat about 31 two ends and riser 32, be provided with arc-like rows water pipe 33, the top of described arc-like rows water pipe 33 is communicated with transverse slat 31.Arc-like rows water pipe 33 is established according to steel pipe 2 inwall, the place that certain arc-like rows water pipe 33 is communicated with transverse slat 31 must be the minimum point on transverse slat 31, water on such transverse slat 31 is clapped to steel pipe 2 and between riser 32 through arc-like rows water pipe 33, milder for water can drain into bottom steel pipe 2 by arc-like rows water pipe 33, avoid causing greater impact to riser 32, and then affect the structural stability of riser 32.
Adopt the underpasses construction method of said structure, comprise the steps:
S1) precast concrete base 1 and steel pipe 2;
S2) excavation pit, sclerosis ground;
S3) first concrete bed 1 is installed, with being arranged on by pre-manufactured steel pipe 2 on base 1 using as underpass primary structure thing, then building carriageway plate and backfill foundation ditch in pipe, finally pouring into a mould road surface, upper strata 5.
This construction method is cut and cover method, and advantage and the safety with cut and cover method are good, difficulty of construction is low, there will not be the risk that road surface in hidden construction process caves in, and also overcomes long shortcoming of existing cut and cover tunneling cycle simultaneously, improves efficiency of construction.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
