Description

A kind of pile foundation displacement auxiliary detection device
Technical field
Engineering pile foundation detection field is the utility model is related to, specially a kind of pile foundation displacement auxiliary detection device.
Background technology
Pile foundation displacement at pile top refers to that in pile driving process adjacent stake produces lateral displacement or stake rises.Main cause is Stake number is more, and soil layer saturation is closely knit, stake spacing is smaller, and in pile sinking, soil is pressed against limit compactness and swelled upwards, adjacent stake Be filled with together.Cause the situation of pile foundation displacement to have:When constructing, pore pressure is adjacent caused by pile sinking in weak soil Stake is pushed side to or is filled with;Stake position unwrapping wire is forbidden, and deviation is excessive;Stake bit flag is lost in construction or extruding deviates, constructor Member's arbitrarily positioning;Earthwork digging method and order are incorrect.The precautionary measures typically used in engineering have:Must not be same during pile sinking When excavation pit, need to treat to be separated by reasonable time excavation after the completion of pile sinking, it is general suitable two weeks or so;Excavation of foundation pit must be led Meaning drainage measure, indwelling side slope;Foundation ditch side must not stack the earthwork, and foundation ditch answers stage excavation more deeply;Pile foundation is carried out in digging process Detect work.At present, common foundation pile displacement amount detecting device mainly has displacement rod-type detection means and displacement wire form detection dress Put two types.During using displacement rod-type detection means, rigid rod is put at foundation pile displacement amount, rigid rod is extended into ground Place, displacement transducer, the disposed outside pipeline of rigid rod are installed at the top of rigid rod.If the hole depth of foundation pile it is larger, it is necessary to More rigid rod connections use, and due to the not reproducible use of rigid rod, it is high that displacement rod-type detection means has installation trouble, cost Deng using shortcoming.Displacement wire form detection means includes comprising mechanical and two kinds of electrodynamic type, mechanical displacement wire form detection means again Two steel wires, a wire connection card head, another steel wire are used to control dop to shrink or open, and two steel wires need to put simultaneously In the hole for entering foundation pile.During measurement, easily winding leads to not control dop by steel wire two steel wires, and then causes to examine Survey device integrally smoothly to take out from the hole of foundation pile, it is impossible to complete measurement task well.Electricity driving displacement wire form detection means is used The electronic dop of cable connection, with the electronic dop of magnet control collapsed or opened, but existing electricity driving displacement wire form detection dress Put and fixed pulley is fixed on datum line beam, the stress of cable and displacement can cause datum line beam to rock, displacement inspection when datum line beam rocks Survey device also to rock therewith, so influence measurement result accuracy.
Application No. 201620356918.4 devises a kind of pile foundation displacement auxiliary detection device, and it is provided with No.1 detection group Part and No. two detection components, No.1 detection components and No. two detection components are by frame, pole, horizon detector and two detections Device forms, and it is that No.1 detection components and No. two detection components are placed on to the place for needing to detect, water that it, which aids in the principle of detection, Flat detector ensures that frame is in horizontality, is diagonally detected by detector, the data of detection can draw pile foundation Whether bearing capacity uniform, the design have the drawback that can not intuitively detection of pier foundation all directions displacement, can not detect Excavation Process pile foundation relative to ground change in location.
Therefore a kind of pile foundation displacement auxiliary detection device is devised, using the probe detection of pier foundation of special angle relative to ground The displacement in face, while the direction of pile foundation displacement is can determine by the conversion of displacement, the maintenance to pile foundation provides important Data supporting.

Embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment further instruction the technical solution of the utility model:
Embodiment 1
A kind of pile foundation displacement auxiliary detection device as shown in Fig. 1~2, by frame 1, ring stand 2, hinge 3, probe 4, level Instrument 5, crane 6, compression frame 7 and fixed disk 8 form.The upper end of frame 1 that two bottoms are connected with each other as shown in the figure supports one Ring stand 2, when in use, the end portion of frame 1 need pre-buried and underground so that frame 1 is relatively fixed with bottom surface.The mesh of the process Be displacement in order to accurately measure pile foundation relative to ground.
Four identical ring stands 2 are installed on the pile foundation displacement auxiliary detection device, passed through between adjacent two ring stands 2 Hinge 3 connects, detachably, and meanwhile it is easy for installation, four ring stands 2 and four hinges 3 just form a concentric circles, peg to be checked Base 9 is located on the circle.The upper surface of each ring stand 2 is mounted on a level meter 5, its purpose is to ensure installation when it is every The level height of one ring stand 2 is identical, improves the accuracy of pile measurement device detection.
Two angles are mounted on the inner surface of each ring stand 2 at intervals of 60 ° of probe, will using hinge 3 After ring stand 2 is fixed, the angle of adjacent two on adjacent ring stand 2 probe 4 is 30 °, as shown in figure 3, the first probe 401 and the Two probes 402 are installed on same ring stand 2, and angle between the two is 60 °, the second probe 402 and the installation of the 3rd probe 403 With on two adjacent ring stands 2, second probe 402 and the 3rd probe 403 between angle be 30 °.Horizontal position is carried out in pile foundation During shifting, it extrudes the quantity of probe 4 and is no more than three.Probe is installed according to the angle, no matter from which direction Displacement, probe 4 can detect the shift length and direction of displacement of pile foundation, simply accurate using orthogonal operations.Its principle of operation As shown in Figure 4.It can be obtained according to angle analysis:Angle between first probe 401 and the second probe 402 is 90 °.Can on probe 4 There is scale, can intuitively reading.If the pile foundation that the detection of first probe the 401, second probe 402 and the 3rd probe 403 obtains Displacement is respectively L1, L2 and L3, and L1 and L3 are respectively positioned on Y, in X-axis, and L2 displacement is decomposed to obtain Lx and Ly:
Lx+L3 ①;
Ly+L1 ②;
The orthogonal merging of result that one formula and two formulas are obtained obtains displacement and displacement of the accurate pile foundation relative to ground Direction.
The upper surface middle position of each ring stand 2 is mounted on a crane 6, and crane is by the first sleeve 601 and elevating lever 602 form, be carved with scale value on elevating lever 602, pile foundation length travel measured, can intuitively read Take.The end face of elevating lever 602 is provided with constrictor 7, and constrictor 7 is made up of second sleeve 701 and constrictor 702.The end of constrictor 702 Face is fixed with fixed disk 8.Fixed disk 8 is bolted with pile foundation 9 during use.Fixed disk 8 is provided with bolt mounting holes 801. Elevating lever 602 is driven to move by fixed disk 8 and compression frame 7 in the lifting of pile foundation 9, so as to measure the distance that pile foundation vertically moves.
The pile foundation displacement servicing unit makes it when in use it should be noted that the part of frame 1 must be embedded in ground It is fixed.Measured by mutual cooperation with base station, can with it is effectively measuring go out the displacement of pile foundation and the variable quantity of ground.
