The specific embodiment
embodiment is shown in Figure 1, insulated column basis under a kind of post that can carry out rectifying by jack up, comprise base plate 1, be fixed on concrete pedestal 2 and the parallels 4 that is fixed on concrete pedestal 2 upper ends on base plate, the thickness of described parallels 4 is 30 millimeters～100 millimeters, can be used for soft foundation, freeze the sinking headframe basis under the vertical foundation condition, the steel headframe basis of production use, also be applicable to various plant equipment basis, when producing differential settlement, can be easily derrick or the equipment of differential settlement be carried out rectifying by jack up, while being used for booth formula sinking headframe, because post tilts, so the upper surface of concrete pedestal 2 is inclined-plane, while being used for other bases, the upper surface of concrete pedestal 2 differs and is decided to be inclined-plane, it can also be horizontal plane, shown in Figure 2, the upper surface of concrete pedestal 2 is inclined-plane, top has the preformed groove 3 that is used for placing jack of X-shaped, on described concrete pedestal 2, be evenly distributed with eight reinforcing bars of the strengthened thread perpendicular to the inclined-plane of concrete pedestal 26 and four derrick leg prepared screw-bolt holes 5 in the periphery of preformed groove 3, the diameter of described strengthened thread reinforcing bar 6 is 20 millimeters, length is 800 millimeters.
Shown in Figure 2, in described preformed groove 3, the cementitious material filler is arranged, cementitious material filler 7 in described preformed groove 3 is M10 cement mortar or C10 weak concrete, one deck cement mortar front cover is arranged on described preformed groove 3, and the cement in described cement mortar front cover and the amount ratio of mortar are 1:2.
Specific implementation process of the present utility model:
Preparation before carrying out jacking, correction comprises:
1, Fundamentals of Measurement deflection, before jacking, correction, first carry out horizontal stringcourse and sheave wheel platform center and namely go up the cross hairs measurement, measures the side-play amount of each basic deflection and sheave wheel platform.
2, be ready to the instrument of the correction such as jack use.
3, carrying out load calculates, checks: the jack group: 1 group 4, top lift should be greater than the load of every supporting leg base plate of derrick.
Whether will check before 4, jack uses qualified.
5,, according to underground gushing water amount situation,, if the underground gushing water amount is larger, should keep in case of necessity normal draining to ventilate.
6, should alleviate the load of derrick as far as possible.
When derrick footing generation differential settlement, derrick produces, and deflection becomes the approximate ratio relation with the sheave wheel platform displacement.At this moment can estimate wire rope and can produce skew in the position of Manhole closing dish, trapdoor, the largest amount of subsidence of derrick footing can be estimated by following formula:
Δh=Δl×L÷H
In formula: Δ h: derrick footing deflection, unit: millimeter.
Δ l: wire rope is in the side-play amount of Manhole closing dish, unit: millimeter.
L: derrick foundation span, unit: millimeter.
H: derrick foundation is the height of day wheel shaft extremely, unit: millimeter.
Direction according to the wire rope skew, can estimate out roughly is which concrete pedestal has produced sinking, when the side-play amount of wire rope surpasses 50 millimeters, to affect and promote safety, just should rectify a deviation, the method of correction is the derrick leg jacking that the derrick deflection is larger, the wedging parallels, and concrete steps are as follows:
With level gauge and transit, the upper cross hairs of horizontal stringcourse and sheave wheel platform center of derrick is observed during jacking, three legs that deflection is larger are distinguished jacking successively to datum grade; Former upper cross hairs on sheave wheel platform overlaps and is as the criterion with the shaft cross line, the position when whether the rope point that falls that at this moment also should check wire rope returns to former the installation
jacking after the derrick footing differential settlement, the principle of correction, it is the derrick leg jacking that derrick is sunk, add parallels after jacking, therefore, make jacking tool jacking reliably, build man-hour at derrick footing, an X-shaped preformed groove is built on top at the concrete pedestal of each derrick, can place 4 QYL50 type jack in the preformed groove 3 of each concrete pedestal, 50 tons of the lifting capacities of each jack, after the concrete pedestal final set demoulding, tamp the hole groove with M10 cement mortar or C10 weak concrete again, fill, tamp, external application 1:2 cement mortar front cover, middle carefully 500 millimeters * 500 millimeters, pour into simultaneously the strengthened thread reinforcing bar 6 of 20 millimeters of diameters in basis, every long 800 millimeters, totally 8 of each concrete pedestals, the intensity that base concrete intensity reaches design more than 75% after, derrick is installed again.
Preformed groove 3 use M10 cement mortar or C10 weak concrete pour into, its objective is when jacking, correction and can dig out more convenient, easily the hole groove, place jack, do not damage former concrete pedestal while digging pit groove, be convenient to jacking, correction, avoided the groove of heavily digging pit when rectifying by jack up, damaged the drawback of concrete pedestal on concrete pedestal 2.
In foundation construction should derrick footing and near permanent leveling observation point is set, its sedimentation situation of periodic observation on ground.
Points for attention during derrick installation:
1, when derrick footing generation differential settlement, derrick produces, and mortar or weak concrete that this basis is reserved in the groove of hole are excavated, and jack is put into reservation hole groove, with derrick jack-up, then adds parallels, placing cement mortar.
2, the stone bolt of derrick, top screw after installation exposes 200 millimeters, and the concrete pedestal face is tightened up a screw, and to expose be 300 millimeters, and car filament length degree changes 400 millimeters into, after sinking, derrick leg is carried out jacking, the former design of every length of old place foot bolt need lengthen 200 millimeters.
Answer points for attention: A, parallels should be placed on the both sides of stone bolt when 3, parallels is laid in derrick installation; B, parallels should expose 20～30 millimeters of steel plate outsides, derrick steel leg bottom, so that adjust, and the distance at parallels and bolt edge can keep 50～150 millimeters, is convenient to the grouting in screw; The height of C, parallels is generally between 30～100 millimeters, as the too high stability that can affect derrick, the too low tamping that is not easy to back-grouting; D, every group of parallels piece number should not surpass three layers, and inclined sizing block uses and is considered as one deck in pairs.
4, derrick installation is complete, to carry out spot welding to the parallels group, to carry out back-grouting in the bolt hole of concrete pedestal, to carry out quadric-plastering on the concrete pedestal face, in the bolt hole of concrete pedestal, back-grouting adopts pea gravel concreten, improve one-level than the concrete grade of concrete pedestal, quadric-plastering adopts the 1:2 cement mortar.
5, after derrick installation leveling, be with horizontal stringcourse pilot measurement to the steel leg of derrick with the shaft cross line pilot measurement to sheave wheel platform, cross hairs on abbreviation, make mark.
Employing when 6, stringcourse, upper cross hairs are as installation sheave wheel platform and frequent observation inspection and correction.
7, horizontal stringcourse pilot measurement can be poured water in the lucite pipe pipe with level gauge or U-shaped water pipe, upper cross hairs pilot measurement transit.
