Additional essential information, the information auxiliary for including using BIM model each pour the storehouse surface design of unit.
The dam BIM model of establishing draws three-dimensional figure according to dam X-Y scheme, and dam BIM model is placed in design
In the frame of reference that unit provides, to guarantee the accuracy of modal position information；
The cutting model is to make cutting plane according to dam parting hierarchical design, and dam model is cutd open by cutting plane
It cuts, obtains independent minimum one by one and pour unit；
It is a bin level that one minimum, which pours unit, as storehouse surface design object；
The additional essential information includes the information such as monolith, dam block, elevation, layer height, concrete strength, specific additional party
Formula are as follows: specify a figure layer, the naming rule of figure layer are as follows: " monolith (flood sluicing block, Overflow Section, non-overflow dam to each block
Section ... takes monolith classification initial+monolith number)-dam block (first, second, third ... they are respectively I, II, III ...)-bottom elevation (m)-liter
Layer height (m)-strength grade of concrete ", such as: " X4-II-340-3-C30 " indicates that flood discharge 4# monolith, second dam block, position in storehouse bottom are high
Journey is 340m, storehouse liter layer height is 3m, strength grade of concrete C30；
The information that the BIM model includes includes monolith, dam block, storehouse surface elevation, rises layer height, concrete strength point
Area, storehouse surface area, cubic amount of concrete, control point coordinates etc..
Compared with X-Y scheme carries out storehouse surface design, a kind of method of the dam storehouse surface design of BIM of the present invention has following excellent
Point:
A: by assisting storehouse surface to design using BIM, storehouse surface essential information directly can be inquired using threedimensional model, more directly
It sees, is quick, efficiently.
B: accurate to obtain the several of the special holes such as dam special form position such as bottom diversion outlet, low-leveled outlet, irrigation gallery
The data such as what size, spatial position improve the accuracy of storehouse surface design.
C: utilizing threedimensional model, controls more analysis comprehensively to construction technology, the temperature of every bin level, and can look into real time
The construction information of asking, count, analyzing each storehouse surface greatly improves construction management level.
