Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.It should be noted that in the absence of conflict, embodiment in the present invention and
Feature in embodiment can be combined with each other.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Refering to fig. 1 and Fig. 2, the pipe gallery waterproof method based on sponge theory of the embodiment of the present invention includes following step
It is rapid:
Step S1 constructs comprehensive pipe gallery structure main body between the braced wall of water-stop curtain two sides.
Specifically, the branch in the water-stop curtain two sides of bored concrete pile high intensity barricade and high-pressure rotary jet grouting pile or cement mixing pile
Construction comprehensive pipe gallery structure main body 1 between revetment.
Step S2 pours two sides slope formula after the completion of comprehensive pipe gallery structure main body construction at the top of the pipe gallery
Waterproof protective layer.
Specifically, determining waterproof after the completion of the construction of comprehensive pipe gallery structure main body 1 with underground pipe gallery design requirement
Grade determines and is laid with coil waterproof layer and puts up benzene plate, and forms closed waterproof layer in periphery.The description of waterproof roll
And the number of plies, it should be according to underground project waterproof grade, level of ground water height and effect of water pressure situation, structure structural form and construction
The factors such as technique determine.After the completion of construction of waterproof layer, the waterproof of two sides slope formula is poured at the top of comprehensive pipe gallery structure main body 1
Protective layer 4.The waterproof protective layer 4 from the gradients of the 1 center of top slope aspect two sides of comprehensive pipe gallery structure main body be 1.5%-
2%, preferably 1.5%.Waterproof protective layer two sides thinnest part with a thickness of 3-6cm, preferably 5cm.Waterproof protective layer 4 can use
C20 pea gravel concreten is built.
Step S3, between the comprehensive pipe gallery structure main body and the braced wall, along the comprehensive pipe gallery structure main body
Several permeable sumps are arranged in longitudinal length, and the water collected in each permeable sump is drawn into municipal administration above the ground
On road or in greenbelt.
Specifically, along the longitudinal length of comprehensive pipe gallery structure main body 1, in its two sides, setting is several permeable catchments
Well 5, the height of permeable sump are the distance from bottom to the ground of the comprehensive pipe gallery structure main body.That is, permeable
5 upper end of sump can be flushed with ground 6.The permeable sump 5 of 1 two sides of comprehensive pipe gallery structure main body can be symmetrical arranged, respectively
The permeable sump 5 is arranged with presetting spacing along the longitudinal length of the pipe gallery main structure 1 in the pipe gallery
The two sides of main structure 1, that is to say, that can be waited between each permeable sump 5 of any side of pipe gallery main structure 1
Spacing setting, such as can be arranged at equal intervals with the spacing of 30-60m, it is preferred that the permeable sump 5 of any side is with 50m's
Spacing is arranged at equal intervals.The wall thickness of permeable sump is more than or equal to 5cm, can build permeable sump 5 using pervious concrete.
Step S4 carries out backfill construction until completing construction at ground elevation between the braced wall of two sides.
Specifically, between the braced wall 2 of two sides and the region backfill element soil of the upside of pipe gallery main structure 1 or
The backfills such as medium coarse sand 3 expect that the absolute altitude on ground 6, degree of being backfilling and compacted, which reaches 0.97 or more, can be completed construction.
The present embodiment can also include: that town road or greenbelt is arranged according to design requirement on ground 6.In addition, also
Automatic water pump 7 can be placed into every mouthful of permeable sump 5 after the completion of construction, when having ponding in permeable sump,
Ponding is drawn on the road on ground or in greenbelt, while underground water can also cleverly be concentrated secondary use, is
Town road increases forms sponge facility together, so that Municipal Infrastructure is preferably served, it is practical, it applies
Work is simple and convenient, without purchasing special material, it is excessively increase cost on the basis of, by sponge city and pipe gallery into
Row organically combines, and provides solid technical support to the popularization in pipe gallery and sponge city.
In actual work, in rainfall, the surface water infiltrates into two sides supporting by the element soil or medium coarse sand 3 of backfill on ground 6
In space between wall 2, when the water content in the element soil or medium coarse sand 3 of backfill increases, the ponding at 1 top of Pipe rack main body
It will dredge along the waterproof protective layer 4 for having been provided with the gradient to piping lane two sides, the ponding of piping lane two sides will pass through permeable collection at this time
Well 5 is collected, and after catchmenting in permeable sump 5 reaches certain water level, automatic water pump 7 will extract permeable sump
5 catchment to ground 6, and extract and spray head or flooding nozzle are arranged on ground, for irrigate ground greenbelt plant or
Rinse town road.
It is above-mentioned obviously it can be concluded that, the pipe gallery waterproof method provided in the embodiment of the present invention utilizes pipe gallery top
The waterproof protective layer in portion is dredged underground water between the side wall of piping lane two sides and braced wall, and herein by intermediate slope aspect two sides
Permeable Jing Ji is set in space and takes periphery underground water, then the water extraction ground flushing road or irrigation passage that take collection using suction pump
Road greening plant is organically combined in sponge city with pipe gallery, and the underground water that is closed in for solving pipe gallery increases infiltration
It leaks out dangerous problem, ensure that the O&M safety of piping lane.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
