Roadbase rain-proof construction method

Abstract

The invention relates to a roadbase rain-proof construction method. The method comprises the following steps that (1) measurement and setting-out work is carried out before starting; (2) a route is cleaned and excavated by using a ground range, cleaning sundries in the area and excavating according to the depth and the range of the engineering design; (3) the surface of a roadbed is cleaned and ground; (4) filling is carried out layer by layer from bottom to top by adopting a layered filling method, and each filling layer is compacted; (5) a liquid seepage-proofing material sprays the surfaceof the uppermost soil layer before rainfall, and an anti-seepage layer with the thickness of 2-5 mm is formed after the liquid seepage-proofing material is cured; (6) after rainfall, the anti-seepagelayer is removed; and (7) the step (4) is repeated until the roadbed construction is finished. The invention provides an improved roadbase layer rain-proof construction method. Compared with an existing construction method, the construction convenience can be improved, the road construction quality is effectively guaranteed, the labor investment is reduced, and the influence on the engineering progress is small.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a rainproof construction method for road bases. Background technique [0002] As one of the important infrastructures for vehicles and pedestrians, road construction quality directly determines the overall traffic quality during the duration of the road and the length of the road maintenance interval. At present, in the process of road construction, the indicators for evaluating the quality of road construction include: (1) structural stability. Certain measures must be taken to ensure the stability of the overall structure; (2) strength, in order to ensure that the subgrade will not deform beyond the allowable range under the action of external forces, the road is required to have sufficient strength; (3) hydrological stability Under the action of surface water and groundwater, the strength of the roadbed will be significantly reduced, especially in season...

Problems solved by technology

In the prior art, the above-mentioned laying of plastic cloth / plastic film is usually carried out manually, and the complexity of the construction site makes it difficult to mechanize the above-mentioned laying work. The process includes conveying, unfolding, laying, pulling and shifting, and fixing of plastic cloth / film, which requires a lot of manpower, time-consuming and laborious, and it is usually difficult to ensure the timeliness of laying plastic cloth / plastic film; secondly, After the rain, in order to resume the construction, the plastic cloth / plastic film must be removed. Since the plastic cloth / plastic film that has been drenched by rainwater is usually covered with muddy water, the removal of the above plastic cloth / plastic film is difficult, time-consuming and laborious, and easy to damage. The progress of road construction has a great influence; moreover, it is usually difficult to achieve full coverage of unfinished roads when laying plastic sheeting / plastic film manually, and rainwater may still seep in
