Description
Technical field
This utility model belongs to engineering quality inspection of the piles checking and accepting technology field, more particularly, to a kind of engineering foundation pile sediment
The detection means of thickness.
Background technology
In engineering with civil buildings, in order to detect the quality of engineering foundation pile and provide acceptance basis, it is often necessary to detect
Sediment of the hole bottom thickness；Now commonly use detection method and mainly adopt core drilling method, edit and record by core boring sampling and to which, measure core
Sediment thickness in sample, sediment of the hole bottom are mainly made up of soil loose during pore-forming or hole pile lining slough, the palpus in boring procedure
Add water to be drilled, sediment is easily washed away and core sample can not be obtained, and to apply certain to drilling rod in drilling process
Pressure, the sediment thickness measured by core sample differed greatly compared with actually.Therefore, prior art is still not ideal enough.
Utility model content
The purpose of this utility model is to provide a kind of detection means of engineering foundation pile sediment thickness, complete by borehole wall
Cross sectional plane unfolded image, reflects borehole wall information intuitive, clearly, is directly acquainted with sediment thickness in visual method and sinks
Slag ingredient.
The technical solution of the utility model is as follows：
A kind of detection means of engineering foundation pile sediment thickness, it is included in the hole being drilled with foundation pile, sets on the aperture in hole
There is a support tripod, one pulley of underhung of support tripod on the ground by aperture arranges one and drills into
As instrument main frame and winch, by cable connection borehole imaging instrument main frame and winch, and hung down in hole by pulley, in cable
Bottom is provided with a hole and pops one's head in.
The detection method that engineering foundation pile sediment thickness is carried out using the device comprises the steps：
1), boring and coring：Boring and coring is carried out to foundation pile；
2), record a video：Borehole wall is recorded a video using borehole imaging instrument, obtain the full-view video image of hole wall；
3), data processing：Data are processed, the full cylinder observation imaging plane unfolded image of borehole wall is obtained；
4), picture of recording a video is identified：Concrete, sediment, the character of supporting course in identification picture, judge pile bottom sediment
Position, thickness and composition.
It is a kind of home position testing method that this utility model carries out video recording using drilling panoramic imagery method to hole wall, by drilling
Hole wall tunneling boring planar development image, reflects borehole wall information intuitive, clearly, is directly acquainted with sediment in visual method thick
Degree and composition；The method has good economy, and testing result is simple and clear, Detection results are good, strong applicability.
Description of the drawings
Fig. 1 is the structure of the detecting device schematic diagram of utility model；
Fig. 2 is the video recording picture schematic diagram that this utility model is collected；
Description of reference numerals：1- borehole imaging instrument main frames, 2- winches, 3- cables, 4- support triangle framves, 5- pulleys, 6- holes
Interior probe, 7- holes, 8- sediments, 9- concrete, 10- supporting courses.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：
As shown in figure 1, the device is included：The borehole imaging instrument main frame 1 on the ground being arranged on outside aperture is connected by cable 3
Winch 2, winch 26 are connected through 4 lower pulley 5 of aperture support triangle frame and with popping one's head in hole by cable 3, so as to by hole
Probe 6 is put in hole 7, by the thickness and composition that understand sediment 8 are imaged to borehole wall.
Implementation steps of the present utility model are as follows：
1), boring and coring：Boring and coring is carried out to foundation pile；
2), record a video：Borehole wall is recorded a video using borehole imaging instrument, obtain the full-view video image of hole wall；
3), data processing：Data are processed, the full cylinder observation imaging plane unfolded image of borehole wall is obtained；
4), picture of recording a video is identified：Concrete 9, sediment 8, the character of supporting course 10 in identification picture, judge stake bottom
The position of sediment, thickness and composition.The width video recording picture that this utility model is collected is as shown in Figure 2.
Certainly, it is more than concrete application example of the present utility model, this utility model also has other embodiments, all
The technical scheme formed using equivalent or equivalent transformation, is all fallen within the protection domain required by this utility model.
