A kind of foundation pit excavation drawing method

Abstract

The invention discloses a method for drawing a foundation pit excavation drawing. The method comprises the following steps: step 1, according to a basic plane drawing of a building, applying building information model software to establishment of a foundation pit mass model, and enabling the foundation pit mass model to be consistent with the design dimension proportion in the basic plane drawing; step 2, laying off on the foundation pit mass model according to the building construction drawing, and forming an excavation model; step 3, applying the software to creation of a two-dimensional foundation pit excavation drawing according to the excavation model; step 4, based on the two-dimensional foundation pit excavation drawing, carrying out foundation pit excavation, and meanwhile, utilizing the three-dimensional foundation pit mass model to assist understanding and review. The method, disclosed by the invention, can effectively solve the problem that the excavation drawing is difficult to draw because when a large-scale foundation pit is excavated, the location and lay-out is complicated; compared with the regular drawing method for the excavation drawing, the method can greatly reduce drawing workload and drawing time to shorten the work period; compared with the regular excavation drawing, in the exported excavation drawing, size marking is realized via the software automatically, so that the phenomena of marking missing and mis-marking can be greatly reduced, and the drawing is high in accuracy.

Description

technical field [0001] The invention relates to a method for drawing an excavation plan of a foundation pit. Background technique [0002] Construction setting-out refers to the positioning of the construction drawings by the construction unit based on the design drawings after the construction site has been leveled. The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. For those with deep excavation and nearby buildings, the foundation pit wall support method, shotcrete retaining wall method, and large fou...
