Background
At present, under the construction condition in winter, the soil layer construction can not reach the corresponding compaction degree, and the progress plan must be buckled, so that the outdoor water distribution project can not be constructed under sufficient conditions. Because underground pre-buried, drain pipe, sewage pipe, downspout, cable duct bank etc. the minimum degree of depth reaches-900 mm, and underground pre-buried pipeline is mostly PE pipe, plastic material pipeline such as UPVC, leads to the unable compaction of basic part thoroughly. The natural settling speed of the soil layer is too low in winter, and the outdoor water scattering caused by the fact that the frozen soil layer settles in spring due to the fact that the base layer cannot be effectively tamped by large machinery and the soil layer compaction degree is insufficient is caused.

Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and effects of the invention, but the present invention is not limited thereto.
The invention provides a winter outdoor water-dispersing construction method, which comprises the following steps:
s1, tamping a foundation part needing outdoor water distribution construction by using a battering ram, and implanting 4 hot-rolled ribbed steel bars with the diameter of 10mm at the root part of a constructional column, namely the lower part of the bottom elevation of the outdoor concrete construction to form a bracket frame with the cross-sectional dimension of 6 multiplied by 14mm, as shown in figure 1; after the bar planting construction of all the hot-rolled ribbed steel bars is completed, a third party is asked to carry out an on-site steel bar drawing experiment, and after the experimental result is qualified, the next construction procedure is carried out. Wherein, the thickness of the reinforcing steel bar protection layer of the outdoor water-dispersing bracket is 20mm in the width direction and 30mm in the height direction.
And S2, chiseling the side face of the ground beam until stones are exposed on the surface of the concrete so as to increase the contact effect of the corbel concrete and the original foundation surface. The wooden template is used for supporting the bracket frame, the bracket is small in size, outdoor water is mostly construction operation carried out in the later stage of engineering, and the usability and the economical efficiency of the template are greatly improved by adding the bracket.
And S3, pouring concrete after the bracket template is supported, and timely performing heat preservation treatment after pouring. And after the strength of the bracket concrete reaches 75% of the curing strength, the bracket template is dismantled.
S4, backfilling with lime soil according to the mass ratio of 3:7, tamping with a tamper, and releasing the slope outwards, wherein the slope releasing coefficient is determined according to the site construction requirement, and preferably ranges from 3% to 5%. And (5) carrying out wood formwork support on the water-dispersing area after slope relief is finished.
S5, pouring a water-spreading surface layer by using C20 fine stone concrete, wherein the thickness of the surface layer is 60mm, spreading cement sand with the mass ratio of 1:1, compacting and polishing, then carrying out heat preservation treatment, removing a water-spreading area template after the surface layer is completely cured (about 7 days), and simultaneously carrying out expansion joint construction.
The constructional column sets up to 4m department in the actual work progress, and industry factory building steel structure post is mostly the setting of center interval 8m column pitch, and outdoor scattered water movement joint is mostly 6~10m department, is about to the bracket and sets up the interval and be the constructional column pitch comparatively reasonable.
The method provided by the invention greatly shortens the construction period, solves the problem of foundation settlement caused by the formation of a frozen soil layer in summer after outdoor water dispersion construction is finished in winter, and avoids the occurrence of secondary reworking caused by damage of outdoor water dispersion.
