Description
Technical field
The present invention relates to pile foundation construction, be specifically related to a kind of long measuring method of pile foundation stake.
Background technology
Nowadays, the foundation construction of a lot of architectural engineerings all uses prefabricated prestressing pipe pile basis.But, prefabricated prestressing pipe pile
Belonging to factory's customed product, must be processed by fixing mould, the specification requirement of product is strict, and prefabricated prestressing pipe pile
Volume is big, quality weight, and transport is got up extremely inconvenient, and supplier is that number one considers, within general one day, supplies once, due to nothing
Method look-ahead construction stake is long, cannot buy prefabricated prestressing pipe pile, work order in practice of construction the most targetedly
Position often occurs because not having the suitable material of specification to use, and the situation that construction cannot continue, claim for eot, efficiency of construction is low
Situation happen occasionally.Due to cannot look-ahead construction stake long, construction also often results in a number of waste of material,
Add the construction cost of enterprise.In a word, the most in advance measuring and calculating pile foundation construction in stake long, lose time, waste of manpower, thing
Power, financial resources, put to no little inconvenience to existing foundation construction work.
Summary of the invention
For solving problem above, the present invention provides a kind of long measuring method of pile foundation stake.Its integrated use tool software, ingenious carries
Take out relevant data and arrange, utilizing the data extracted to carry out the calculation of the length of bored pile.Before construction, predict that construction stake is long,
Unit in charge of construction can carry out capital budgeting, controls fund cost more accurately, and site operation personnel also can carry out material targetedly
Material buying, it is to avoid occur being not suitable for a large amount of waste, claim for eot, the units in charge of construction of the material caused due to pile for prestressed pipe specification
The series of problems that work efficiency is low, this pile foundation stake long measuring method step is simple, science, practical give foundation construction work
Bringing convenience, measuring and calculating cost relatively prior art does not increase, and but fundamentally solves current pile foundation by practical application
The long realistic problem that cannot shift to an earlier date budget of plinth stake, consequent economic benefits, social benefit is huge.

Detailed description of the invention
The invention provides a kind of long measuring method of pile foundation stake, compare with existing technology, this long measuring method of pile foundation stake
Be characterized mainly in that: realized the extraction of particular data by the integrated use of tool software, calculate stake by the arrangement of data
Long.It is as follows that this long measuring method specifically calculates step: the first step, with CAD mapping software by the electronic edition construction drawing of designing institute
Stake position on paper is numbered, and design stake top mark height enters the rock degree of depth plus certain formations after deducting the buried depth of certain formations, its value
Being exactly that construction stake is long, as it is shown in figure 1, the 1-6 rock stratum prefabricated prestressing pipe pile in figure can enter, No. 7 are expressed as apoplexy
Changing rock stratum, prefabricated prestressing pipe pile cannot be introduced into this rock stratum, and the degree of depth that pile tube enters strongly weathered sand-rock is generally fixed value, specifically
Need to carry out comprehensive value according to field apparatus model and design requirement etc., it can be seen that calculate specific rock below every pile accurately
The Huanghai Sea elevation of layer is particularly significant；Second step, extracts the accurate coordinate of each position and the data such as stake top mark is high；3rd step, makes
With Earthwork calculation software, the certain formations equal pitch contour in exploration report is carried out sliding-model control；4th step, by the electronics of designing institute
Version construction stake bitmap is according to coordinate relation, in the certain formations equal pitch contour electronic edition drawing being added in surveying institute's exploration report；
5th step, uses multi-section-line order, is attached in the center of circle of each position, makes the multi-section-line of one or more Guan Bi；
6th step, after adding piling foundation plan according to coordinate relation, can find nearest two discrete point according to coordinate relation, according to stake position
And the position relationship between known elevation discrete point, can obtain the rock stratum buried depth (elevation of stake site) at stake position, such as figure institute
Showing, in elevation H, H=-2+ ＜-2L2/ (L1+L2) the ＞ figure at stake position, 1 represents the position of stake position, and 2 represent that elevation is the distance of-4
The nearest discrete point in stake position, 3 represent the discrete point that distance stake position that elevations are-2 is nearest, and L1 represents that a distance of positions is from 2
The distance of number discrete point, L2 represents the distance of positions distance from No. 3 discrete points, buries by calculating the rock stratum obtained on each site
Deep data；7th step, extracts the buried depth data that certain formations is relevant；8th step, uses EXCEL software, by the most each
The coordinate figure of stake position determines the buried depth data of the certain formations of each position；9th step, obtains every by data compilation and calculating
The theoretical construction stake of individual stake position is long.
