Abstract
The present invention relates to reverse construction, more particularly to a kind of contrary sequence method underground engineering well.A kind of contrary sequence method underground engineering dewatering well for not influenceing traffic, the drainpipe of the dewatering well is horizontally installed in roadbase, and water in dewatering well is discharged to the rain double-edged fine-toothed comb well for closing on, and the drainpipe is steel wire rubber drainpipe.Dewatering well after present invention construction does not expose the part on road surface; thoroughly solve obstacle of the precipitation to motor way travel road surface; not by the obstacle of warning bucket; original car lane can all be utilized; the dewatering well top for reducing every 10 ~ 15m mono- along original sets original lane width that warning bucket, drainage pipeline etc. occupy; avoid and possibility that dewatering well road surface safeguard measure is repeatedly damaged, reduce multiple the artificial of replacing, material cost input.
Description
Technical field
The present invention relates to reverse construction, more particularly to a kind of contrary sequence method underground engineering well.
Background technology
With continuing to develop for China's urban construction, land resource it is gradually rare, consider wartime and people's air defense needs usually, increasing one, tier 2 cities build underground civil defense engineering under the commercial street road of ripe prosperity.Because of the particularity in residing geographical position, influence of the new construction to surrounding environment is reduced in order to try one's best, reverse construction is used more such underground engineering.First construct top board, recover after road surface is open to traffic, then wall of constructing（Post）, base plate of finally constructing.
The dewatering operation of later stage top board sub-body structure construction premise, certainly will will have great difficulty in such bustling shopping street construction, especially the large-scale well point in marble road motor vehicle road in both sides of the road per 10 ~ 15m of extensions or so（The precipitation radiation scope of conventional large-scale well point）A dewatering well need to be laid, construction operation and prior to main body construction finishes that rear is dismountable with main structure construction, and recovers the pavement of road at the position of well point, and the cycle is more long.What extensions both sides were so many in marble road motor vehicle road go out road surface well point will all bring detrimental effect to the image of the trip of common people, the smooth of automobile traffic, urban civilization modernization, especially at large-scale retail shop square and intersection position, the influence of the special circumstances such as parking lot rotation angle position is more obvious.
Conventional method is to take the method for setting up the eye-catcher for putting a security warning barrel separately in each dewatering well outlet face now, but quantity is more, density is big, take the current area of road, and drainage pipeline crosses the influence to car lane such as road and still exists, simply serve the safe warning function of certain effect, but privileged sites automobile traffic obstacle can not be released at all, over time, inevitably by people, it is destroyed in the time period of wagon flow peak period, the phenomenon such as break, in order to reach the effect of civilized town road and security warning, certainly will will have to again to destroy warning bucket carry out it is secondary, three inferior replacings are installed.Also have and dewatering well is arranged in greenbelt, but due to place limitation, it is also infeasible.
The content of the invention
Present invention seek to address that the drawbacks described above of prior art, there is provided a kind of contrary sequence method underground engineering dewatering well for not influenceing traffic.Dewatering well after present invention construction does not expose the part on road surface; thoroughly solve obstacle of the precipitation to motor way travel road surface; not by the obstacle of warning bucket; original car lane can all be utilized; the dewatering well top for reducing every 10 ~ 15m mono- along original sets original lane width that warning bucket, drainage pipeline etc. occupy; avoid and possibility that dewatering well road surface safeguard measure is repeatedly damaged, reduce multiple the artificial of replacing, material cost input.
What the present invention was realized in：A kind of contrary sequence method underground engineering dewatering well for not influenceing traffic, the drainpipe of the dewatering well is horizontally installed in roadbase, and water in dewatering well is discharged to the rain double-edged fine-toothed comb well for closing on, and the drainpipe is steel wire rubber drainpipe.
A kind of described contrary sequence method underground engineering dewatering well for not influenceing traffic, the drainpipe is laid out pre-buried in advance when roadbase is constructed.
By well, the dewatering well selects DN500 spheroidal graphite cast-iron heavy well cover and supporting bearing to a kind of described contrary sequence method underground engineering for not influenceing traffic.
A kind of described contrary sequence method underground engineering for not influenceing traffic by well, before Paving roadways pitch reserve by the well lid and walling crib position, and bitumen layer starts to install well lid after completing and concrete walling crib of constructing is fixed.
￠ 50mm are selected in the outer draining of downcast well pipe of the present invention（Depending on geological condition）Transparent wire rubber pipe, roadbase is laid out pre-buried in advance when constructing, and drainpipe is connected to close inlet for stom water（Rain grate well）.Choose DN500 spheroidal graphite cast-iron heavy well cover and supporting bearing（Well lid is neglected greatly depending on well casing diameter, and well lid type is depending on highway layout load）.Well lid and walling crib position are reserved before Paving roadways pitch, bitumen layer starts to install well lid after completing and concrete walling crib of constructing is fixed, protection precipitation well head, process maintenance, road normal pass are played a part of with this.
People, wagon flow traffic reach barrier free accessibility in the present invention, have recovered the due magnitude of traffic flow in original track；Later stage dewatering construction is convenient and swift, can greatly reduce people, machine, the multiple input of material in work progress, increases economic efficiency；Potential safety hazard is excluded, and dewatering operation effect is ensured, civilized road surface, harmonious traffic, business are shared.
Brief description of the drawings
Fig. 1 is schematic diagram of the invention.
Specific embodiment
As shown in figure 1, a kind of contrary sequence method underground engineering dewatering well for not influenceing traffic, the drainpipe 2 of the dewatering well 1 is horizontally installed in roadbase 3, and water in dewatering well is discharged to the rain double-edged fine-toothed comb well for closing on, and the drainpipe is steel wire rubber drainpipe.
A kind of described contrary sequence method underground engineering dewatering well for not influenceing traffic, the drainpipe is laid out pre-buried in advance when roadbase 3 is constructed.
By well, the dewatering well selects DN500 spheroidal graphite cast-iron heavy well cover 4 and supporting bearing 5 to a kind of described contrary sequence method underground engineering for not influenceing traffic.
A kind of described contrary sequence method underground engineering for not influenceing traffic by well, before Paving roadways pitch reserve by the well lid and walling crib position, and bitumen layer 6 starts to install well lid after completing and concrete walling crib of constructing is fixed.
