Description

Omnibearing anti-inclination stability detection system and method for circuit concrete pole
The technical field is as follows:
the invention relates to a system and a method for detecting omnibearing anti-inclination stability of a circuit concrete pole.
Background art:
in recent years, the power grid industry has several accidents of line concrete pole collapse, which cause casualties and property loss, and besides economic loss, the accidents have great negative effects on the operation center of workers and the image of enterprises.
Apart from the line pole-falling accidents caused by severe meteorological disasters and geological disasters, a considerable part of pole-falling accidents are caused by human factors: unreasonable planting process flow, foundation pit condition which does not accord with design requirements, accessory installation deficiency, foundation geological condition which does not accord with requirements, incomplete investigation and the like. All the errors cause that the erected tower has insufficient anti-tilting moment and poor stability, and the tower overturns under the action of the allowable working load to cause accidents.
The method is characterized in that the anti-inclination stability of the concrete pole of the new line is detected, the stable working torque of the concrete pole is accurately measured within an allowable range, and the action time and the offset residual value of the torque exceeding a certain allowable limit are checked and measured, so that the aim to be achieved is achieved.
1. The new vertical line concrete pole is equivalent to a cantilever beam in the vertical direction, the ground end is a fixed end, and the pole tip is a free end. The concrete pole that accomplishes the cultivation is because meteorological factor and follow-up technological requirement, except bearing the axial action of gravity of self weight loading, the operation and operation process still can receive following exogenic action: the gravity and the eccentric moment of a pole climber, the gravity and the eccentric moment of line equipment such as iron accessories, hardware fittings and the like, the wind load moment of the pole climber and objects hung on the pole climber, and loads caused by other physical impacts. Therefore, the line concrete pole is required to bear the axial pressure, the pole piece has certain bending moment resistance, and the ground end has better specific pressure performance and bending moment resistance.
1.1, the mechanical property of the concrete rod, and the qualified rod piece produced by a concrete rod manufacturer can be delivered to a factory after the bending resistance and the axial compression load resistance of the rod piece are ensured.
The transportation and loading and unloading scheme of the concrete rods is designed based on the characteristic that the concrete rods are slender rod pieces, so the transportation and the carrying of the concrete rods can also meet the requirements.
The concrete pole hoisting operation generally adopts a two-point or three-point system hoisting mode to decompose the weight of the pole piece, and ensures that the bending moment value of the maximum bending moment point is within an allowable range.
And 1.2, the mechanical requirements of the concrete pole are met, and the concrete pole after being planted is a vertical pole piece and is acted by gravity and bending moment.
The gravity borne by the concrete pole is transferred to a ground foundation pit by the pole body, and the concrete pole can be directly planted when the bearing specific pressure of the foundation pit is good; when the foundation pit bearing specific pressure is not enough, the contact area between the foundation pit bearing specific pressure and the stratum is increased by arranging the chassis and the chuck, and the requirement for bearing the foundation pit specific pressure is met.
The bending moment born by the concrete pole after being planted is also transferred to the foundation pit through the pole body, and the soil retaining layer formed by backfilling and tamping the foundation pit is balanced. For example, the operator on the rod is two persons, each person has a weight of 75kg, and the gravity center and the rod axis are 500mm, and the moment applied to the rod by the two persons is: 75 kg.m. And the front and rear soil retaining of the backfilled foundation pit also generate a bending moment of 75kg & m to balance the soil retaining. If the maximum bending moment value of the retaining soil is less than 75kg · m, the balance of the retaining soil is destroyed, and the erected rod member is deflected and deformed until the rod member falls under the action of the moment generated by the personnel, so that an accident also occurs.
1.3, set up concrete pole stability moment parameter, in the actual work process, the moment of flexure that the concrete pole bore is a variable, and the moment of flexure source has: the operation condition, the meteorological disaster condition, the design and the construction process quality. The mechanism, vector direction, superposition and offset factors, synchronism and the like generated by the method cannot be used for establishing a mathematical model for detailed calculation.
The concrete parameter requirements of the anti-inclination stable moment of the concrete pole can not be found through a large amount of collected and consulted data, the balance mode is different due to the fact that the concrete pole has different purpose pole types such as straight lines, corners and terminals, and the concrete pole type is selected through a fuzzy estimation mode.
Setting: the accessory installation of the new concrete pole is the double-person pole climbing cooperation operation, the maximum bending moment of the new concrete pole is coaxial on the same side of an operator, and the new concrete pole also has the installed objects such as cross arms, top frames and the like.
The weight is 75 kg/person, and the accessories are 30 kg;
the distance between the person and the accessory is 0.8m from the axis of the rod;
generating a bending moment M:
M=F*L=180*0.8=144kg·m
margin correction coefficient k is 1.2
Safe and stable bending moment value MStable
MStable=k*M=172.8kg·m≈175kg·m
Therefore, M is selectedStable175kg · m is used as a reference parameter for the design of the present item.
