A support removal method for deep foundation pit based on dynamo

Abstract

The invention relates to the technical field of deep foundation pit construction, in particular to a dynamo-based deep foundation pit support removal method, which includes the following steps: the first step, preliminary preparation: the second step, using dynamo to split the support: the third step , the division of support division points: the fourth step, determine the location of the support area: the fifth step, use the dynamo operation to obtain the support removal length: the sixth step, divide the support division points, and obtain the division point coordinates: the seventh step, Generation of split supports. The method provided by the invention quickly realizes the support removal on the basis of the BIM model, can greatly improve the construction efficiency, optimize the construction process, and ensure the construction quality.

Description

technical field [0001] The invention relates to the technical field of deep foundation pit construction, in particular to a dynamo-based deep foundation pit support removal method. Background technique [0002] With the increasing shortage of urban construction land, the horizontal expansion of the land area can no longer meet the development needs of the current construction industry, so the deep foundation pit projects that are developing in the direction of depth are gradually increasing. In order to meet the safety production needs of construction and protect existing buildings, deep foundation pits are generally designed with a deep foundation pit support system of horizontal support and vertical support system. When the construction of the underground structure reaches a certain level, the inner support must be removed because the inner support member affects the structural construction. [0003] The support removal of deep foundation pit has certain particularities, ...

Problems solved by technology

The removal sequence of supporting components in deep foundation pits is affected by the position of the tower crane on the construction site, the lifting weight, the design and layout of the supporting beams, the location of the supporting beams, the stability of the scaffolding on the bottom platform, the transportation of the removed supporting components to the designated location, the layout of the buildings around the foundation pit, and the site. Due to the influence of various factors such as the construction environment, due to the interference of various uncertain factors, there are hidden dangers in safety and stability in the removal of deep foundation pit support components, which may lead to accidental damage to the support system and foundation pit system, causing Accident; the integrity of the support beam is unstable, and a collapse accident occurs; it causes large displacement and deformation of the supporting piles around the foundation pit, causing the foundation pit to collapse and damage the surrounding buildings; it causes harm to construction personnel and equipment
