Innovation And Application Of Construction Technology Of Enclosure Pile In Pebble Stratum

According to the technical dilemma of design and construction encountered in the application of several kinds of geotechnical engineering in the pebble stratigraphy,the paper starts from the actual demand of the project,through the literature research method,the investigation method,the case study method and so on The briquetting pile,TRD method,the development and application of the barrier construction,these several methods to expand the application to the pebble stratum,with a certain economic value and social benefits.Research on the Innovative Application of Occlusal Piles,including the Pile Material of Bonding Pile and the Innovative Research of Construction Machinery.The pile material can be replaced by the bite between the reinforced concrete piles and the bite between the cement pile and the reinforced concrete pile.The cement pile can be stirred in situ or pumped with a high pressure mud pump into the mixed mud The Choose the most suitable construction machinery for construction,construction machinery by the drum drive with the rotary drilling rig instead of the conventional fulltube rotary drilling rig.The occlusal piles are replaced by conventional hard-cutting bite instead of soft bite.In this paper,the occlusal piles of rotary drilling rig and long spiral press pile in the pebble stratum are studied in a case-by-case manner.TRD is difficult to construct in hard gravel strata and strata containing more obstacles.In this paper,the construction method of TRD construction technology,TRD construction efficiency and mechanical wear are reduced,and the construction of TRD construction technology is improved by local breakthrough hole and interval hole.Has achieved good results.In the practice of wreckage,it is necessary to take into account the construction cost period,give full play to the subjective initiative,and utilize the existing machinery in the site,which may be the most suitable.Only in the site of the existing construction machinery can not meet the requirements of the barrier,it is necessary to introduce a new construction machinery for wreckage.This paper puts forward three methods of removing the piles of the fully mechanized double-casing fast-drawing method.
