Description
Technical field
The invention belongs to technical field of civil engineering, particularly a kind of abnormity stake sectional dimension survey instrument and measuring method thereof.
Background technology
In Soft Ground engineering fields such as highway, high-speed railway; Through changing the concrete-pile cross-sectional form, improving the unit materials rate of utilization of strength, when saving the building materials consumption, improving bearing capacity of pile foundation is one of long-term important topic of paying close attention to of researchist.Before the present invention; Chinese patent " a kind of Y shape concrete filling pile "; The patent No.: ZL01221710 discloses that a kind of side surface area is big, load-bearing capacity is strong and technology is simple, low cost of manufacture, Y shape concrete pouring abnormity stake that environmental pollution is little; The pile body transversal section is Y-shaped, and section outsourcing circular diameter is between 0.5 ~ 2 meter, and pile length is between 5 ~ 35 meters.In addition; Chinese patent " cast-in-situ X-shaped concrete pile construction method "; The patent No.: ZL200710020306.3; " the heavy die device of the cast-in-place X-shaped stake " patent No.: ZL200720036892.6 discloses and has adopted cast-in-place way to process the xsect abnormity stake that shape of cross section is similar English alphabet X-shaped.This type stake type improves a side specific surface area through changing shape of cross section; Improve the side-friction force between stake side surface and the pile peripheral earth; Thereby improve bearing capacity of pile foundation under the concrete amount situation such as unit strength on concrete material utilization factor, raising; And this novel pile constructing process is simple, workable, is convenient to quality control, detection, and bearing capacity of single pile is high; In Soft Ground engineerings such as highway, municipal works, obtained using widely.
Stake of Y shape and X-shaped stake all belong to the abnormity stake, and there is a concave arc section in the pile body xsect.As one type in the vibrator sunk pile; Have a certain amount of full in the concrete spouting process; Cause the stake of Y shape or X-shaped stake cross sectional dimensions and the design section size of cast-in-site to have difference; The radian that is the concave arc section can be compared variation to some extent with design load with radius, so the shaping form that on-the-spot excavation detects a cross section is one of means of special-shaped quality of pile detection.Concrete fullness coefficient is relevant with all soil pressures of stake; Generally little near all soil pressures of face of land stake, the concrete fullness coefficient is big, and is dark more away from the face of land degree of depth; Soil pressure is big more; The concrete fullness coefficient is more little, so needs to measure the sectional dimension along the pile body diverse location behind the pile body excavation, i.e. measurement to the stake cross sectional shape comprises that the stake top is measured and pile body is measured.The stake top is measured and directly adopted common each spot size of ruler measurement stake top to get final product, and is simple; But it is bigger that pile body is measured difficulty, owing to there is the concave arc section, therefore can not use common ruler to measure the stake sectional dimension.This technical barrier is still unresolved in engineering at present.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of abnormity stake the in-site measurement instrument and measuring method of degree of depth sectional dimension arbitrarily measured is provided.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of abnormity stake sectional dimension survey instrument; Comprise that the edge has the main scale that scale all is set, secondary chi, inferior chi; One end of main scale and an end of secondary chi are connected through coupling shaft, and the main scale end that is enclosed within on the coupling shaft is provided with 0 ° ~ 360 ° circular arc scale; Coupling shaft and secondary chi are fixed together, and are provided with pointer at the coupling shaft end face, and its pointer direction is consistent with secondary chi direction; Main scale passes through to flexibly connect buckle with time chi, and secondly chi can slide along the main scale direction, also can slide along the direction perpendicular to main scale; It flexibly connects the button side air level is set.
One end of said chi is arranged to tip-angled shape, makes chi end and testee form point and contacts, and improves precision.
Said flexible connection button is processed by material transparent, makes when measuring and does not block scale, can make with organic glass.Flexible connection is buckled in mutually orthogonal both direction and has two connecting holes, and main scale passes a top connecting hole, and inferior chi passes a following connecting hole.
A kind of abnormity stake of the present invention sectional dimension on-site measurement method may further comprise the steps:
Step 3, the revolute pair chi is one side make the planarea between adjacent two concave arcs of being close to of its band scale, radian number and secondary footage value that record pointer points to;
Step 4, numerical value on the record main scale, its numerical value is chord length, i.e. the air line distance of abnormity stake concave arc section two-end-point, and the position of definite string mid point;
Step 7 moves this survey instrument to next concave arc fragment position, and repeating step (2)～(6) finish up to all concave arc section measurements.
Advantage of the present invention and effect are:
Cooperate through the connection between main scale, secondary chi, the inferior chi dexterously, realized the measurement of odd-shaped cross section size, solved an on-the-spot abnormity stake section gauge difficult problem.Air level is set on main scale, and each scale is in the surface level position all the time when having guaranteed measurement.Can form 0 ° ~ 360 ° angle between main scale and the secondary chi, measurement range is big.Each scale fits tightly with point or limit on the outline of abnormity stake cross section during measurement, and directly reading obtains geometric parameter from the scale, and measuring accuracy is high.Apparatus of the present invention are measured cast-in-place X-shaped stake or the Y shape stake sectional dimension except can be used to, and also can be used for measuring other any sectional dimensions that have concave arc section polymorphic structure.This survey instrument and method are simple and practical.
