101 layers of this engineering main buildings, 492 meters high.The 1st～4 layer of steel column of main building aerial part is 3 layer of one joint, and the 5th～6 layer respectively be a segmented column, this engineering main building first road collar tie beam just occurs up to the 6th layer.We suit measures to local conditions, and adopt " external control method ", the high gift of money for a friend going on a journey of will standing entirely to be set up in secondary control net reference mark point position, directly make progress the reference mark is passed in the 2nd～6 layer on arbitrary destination layer, as this destination layer axis measuring with to the foundation of steel column in place, correction.This engineering adopts in the external control method, and the elevation angle is less than 30 degree, and measuring accuracy is higher, and operation is also convenient.The external control method is in buildings (structures) outside, adopts transit, controls the stake position according to building axis and carries out a kind of method that the throwing vertically upward of axis is surveyed.Utilize full station high gift of money for a friend going on a journey coordinate collection and setting-out function that axial reference is put measuring belongs to the external control method to the method for destination layer deriving method in addition.Because vertical lead transmits angle should be less than 30 degree, so the external control method generally is only applicable to the lower buildings of overall height.
The 7th layer of this engineering and more than because the number of plies is too many, highly too high, the place is again little, controls net so adopt the internal control method to transmit measurement plane vertically upward.Because the banded truss of this engineering is to establish together every 12 layers, to take all factors into consideration used laser vertical instrument itself again and transmit the restriction of distance measuring accuracy, a measurement plane control reference point position transfer layer is set up in decision every about 10 layers below the 400M.The internal control method is to set up measurement plane control net on high-rise building sole plate or intermediate conversion (station) layer, and need to throw the transfer hole that 200mm * 200mm is reserved in the measuring point relevant position on the destination layer up, the vertical directrix principle of application is carried out the vertical throwing survey of measurement plane control net, measurement plane is controlled net throw vertically upward and measure on arbitrary destination layer, as the foundation of this destination layer axis measuring.The internal control method divides messenger wire to weigh down method and plumb aligner method.The plumb aligner method is divided into zenith collimation method and nadir collimation method again.Zenith collimation method is a kind of method that adopts plumb aligner the reference mark to be thrown vertically upward survey to zenith direction.
Precision in order to guarantee that as far as possible measurement plane control net transmits vertically upward reduces cumulative errors, and hot spot satisfies the operation requirement when guaranteeing to transmit simultaneously.At the 10F, 20F, 30F and the 41F that control reference point position transfer layer below the 41st layer as measurement plane, all be to transmit vertically upward from ± 0.000 first floor measurement plane control net.The measurement plane control net of 50F transmits from 41F and forms, to satisfy the measurement needs that 57～61 layers of core tube transformational structure are installed.
According to construction speed, Steel Structure Installation is early than civil engineering within the walls for the core tube, and girder steel is installed and then lagged behind civil engineering again in the core tube, at this moment still mutual intervisibility between the core tube inner control point.In order to guarantee that the core tube reaches an interior Steel Structure Installation within the walls, the measurement update of the outer steel column of convenient again tube makes full use of door opening and sets up instrument, after the 50th layer of SURVEYING CONTROL NETWORK is delivered to the 61st layer, make horizontal control network reference point position transfer layer.This layer is finished floor for transformational structure, has both guaranteed the stability of horizontal control network, can satisfy superstructure construction needs again.The reference point position transfer layer of measurement plane control net is built up in the 71st layer, 79 layers, 91 layers and 96 layers respectively according to the variation of structural plan more than the 61st layer, and its measurement plane control net is all laid from next horizontal control network reference point position transfer layer transmission.The concrete route of measurement plane control net reference point position transfer layer transmission is seen Figure 22.
The transmission vertically upward of the floor SURVEYING CONTROL NETWORK within the horizontal control network reference point position transfer layer is carried out once every 3～4 layers, all lay from vertical transmission of the initial transfer layer of this section measurement plane control net, both can take into account the segmentation form that this engineering main building steel column is about 3 layer of one joint, totally three layers axis measuring and Steel Structure Installation are measured needs can to satisfy the destination layer upper, middle and lower again.As: construction more than the 71st layer, transmit SURVEYING CONTROL NETWORK to the by the 71st layer of transfer layer and carry out the axis measuring again for 74 layers, can satisfy the measurement operation of 73F, 74F, 75F; The 77th layer of SURVEYING CONTROL NETWORK still upwards transmitted from the 71st layer of transfer key horizon, both effectively reduced cumulative errors, satisfied the construction needs again.
For elevation control and transmission, in the construction of super highrise building vertical survey, the main method of elevation transmission has vertically draws steel ruler to measure, hang steel ruler in conjunction with three kinds of modes such as spirit-leveling instrument measurement, the complete high gift of money for a friend going on a journey measurements in station of employing up and down.Because the cross-operation of this engineering multiple operation is many, insert the operation of finishing, curtain wall installation again in advance, so vertically draw the method for steel ruler to adopt up and down.The complete high gift of money for a friend going on a journey measurement in station has the precision height, the advantage that cumulative errors is little.Hanging the method that steel ruler measures in conjunction with spirit-leveling instrument has easy and simple to handle, can transmit at any time with the rising of floor again, the correct upwards transmission fast of numerous complicated absolute altitude in the work progress can be guaranteed timely and effectively, and advantages such as not only making things convenient for but also can check mutually can be transmitted by many circuits simultaneously.
We consider the high gift of money for a friend going on a journey range finding in full station oversize influence and the vertical sighting condition restriction of this engineering to precision according to adopting the complete high gift of money for a friend going on a journey in station and hanging the advantage of steel ruler in conjunction with spirit-leveling instrument measurement elevation; Consider and hang the restriction that steel ruler is subjected to 50 meter ruler length.So we adopt full station elevation instrument measurement method,, vertically upward, every about 10 layers, transmit an elevation control reference point position layer from ± 0.000 floor face.For the survey of drawing of each destination layer elevation between the layer of elevation control reference point position, we adopt to hang steel ruler and implement in conjunction with the method for spirit-leveling instrument.The result who draws survey for the destination layer elevation conforms to measurement of the level again and adjusts deviation, to guarantee vertical accuracy and the precision of transmitting of elevation.
