Problems solved by technology

Therefore, the concrete mixer truck during the construction phase of the main building can only be parked on the construction road outside the retaining wall of the garage. The concrete must be transported through hundreds of meters of horizontal pipelines to reach the location of the main building. Because the horizontal pipelines are too long, pump blockages often occur. The efficiency of concrete pouring is greatly reduced; engineering vehicles such as material transportation and garage roof covering soil can only be parked on the construction road outside the retaining wall of the underground garage after being unloaded and transported twice, resulting in a substantial increase in the comprehensive cost of construction and the construction period. It has greatly affected the construction progress and economic benefits, and has become a national universal technical problem that needs to be solved urgently

Abstract

The invention belongs to the crossing field of design of a building structure and a construction technology, and particularly relates to an underground garage roof design load and engineering vehicle load comparison construction method. The method includes the following steps that firstly, the allowable load design value of an underground garage roof is calculated; secondly, equivalent uniformly distributed load design value of an engineering vehicle is calculated; thirdly, the allowable load design value of the underground garage roof and the load design value of the engineering vehicle are compared for calculation; fifthly, the driving boundary line of the engineering vehicle is formed through painting to meet the requirement; sixthly, the engineering vehicle runs on the underground garage roof. Compared with a traditional construction method, the engineering vehicle can directly reach the needed position of a main building from the garage roof, in-situ conveying of main building concrete is achieved, engineering materials can be directly transported in place, secondary carrying of construction materials is omitted, the construction period can be substantially shortened, a large amount of comprehensive construction cost is saved, and the environment-friendly construction requirement for high efficiency and energy conservation is met.

Description

technical field [0001] The invention relates to a construction method for comparing the design load of the roof of an underground garage with the load of an engineering vehicle, which belongs to the intersecting field of architectural structure design and construction technology, and is suitable for well-shaped beams, primary and secondary beams, membrane shells and laminated boxes (the upper surface needs to be laid with anti-corrosion Calculation and construction of driving engineering vehicles on the roof of all underground garages in floor structure systems such as punching steel plates. Background technique [0002] In recent years, the form of huge underground garages that run through the field in high-rise buildings has been widely used in the design of all parts of the country. However, the relevant design and construction specifications currently lack calculation models and construction methods for engineering vehicles driving on the roof of the underground garage. ...
