Construction method for treating soft groundwork surface layer by using bamboo web

Abstract

The invention provides a construction method for treating soft groundwork surface layer by using bamboo web. Bearing forces of different soil cover thickness are elevated by a flat-plate loading test,and interrelation of allowed bearing forces is educed according to construction equipment, reinforcing material and soil cover thickness, by analyzing allowed bearing forces by using theoretical formula, applicability of the theoretical formula in existence and efficiency factor of the bamboo web construction method are analyzed, which are used as base data of economic and safe surface layer treating construction method. The method comprises steps of: designing the bamboo web based on design scheme of the invention; arranging the bamboo web on soft groundwork based on soil cover thickness ofthe bamboo web designed with proper interspace according to the design scheme, building in border piles on at least a corner of the bamboo web; paving construction fibre for separation on the bamboo web; paving soil sand on the construction fibre for separation to form cover soil layer; paving sand on the cover soil layer to form sand soil layer; carrying out flat-plate loading test on the soft groundwork to affirm bearing force of the groundwork.

Description

technical field [0001] The present invention relates to a construction method of using bamboo nets to treat the surface of soft ground, especially in the surface treatment method using bamboo nets, the existing method of proposal in the mountain and the bamboo nets designed and set up according to experience are used to pass through the large flat plate on site The load test evaluates the bearing capacity of different covering soil thicknesses, and derives the relationship between the allowable bearing capacity according to the construction equipment, reinforcement materials, and covering soil thickness respectively. By analyzing the allowable bearing capacity using the known mountain theory formula, the current It has the applicability of the theoretical formula and the efficiency of the bamboo mesh method, and is used as a basic material for an economical and stable surface treatment method. Background technique [0002] Recently, in order to secure large-scale new harbors...
