The construction method of digging stake holes clear hole device of revolving of the present invention is carried out according to the following steps: 1. settle to revolve and dig stake holes clear hole device to rotary drill rod end; 2. this is revolved and dig stake holes clear hole device and be inserted to bottom stake holes, and fix after the some circles of slow rotation; 3. input Compressed Gas to Compressed Gas pipeline, meanwhile input foaming agent; 4. start and take out pulp pump, carry out taking out slag; 5. after circulation several times, scarfing cinder completes, and extracts hole device clearly, draws off dregs.
Be described below more specifically:
Composition graphs 1, arrangement is revolved and is dug stake holes clear hole device to rotary drill rod end, then this is revolved and dig stake holes clear hole device and be inserted to bottom stake holes, and the some circles of slow rotation make hole device clearly insert the soil body, then by control room, Compressed Gas or foaming agent are inputted Compressed Gas pipeline 7 or foaming agent pipeline 8 by air inlet port, exported by duct bottom again and discharge, make clearly in the device of hole sediment be suspended in liquid, now, restart and take out pulp pump 2, sediment mixed liquor is pumped under the effect of taking out pulp pump, sludge collection room 9 is drained into again by the first slag notch 5 and the second slag notch 6, sediment drops down onto on filter screen 3, because filter screen can be permeable, but can stop that sediment particle falls into stake holes, in sediment, moisture can also be discharged by the circular treatment hole 11 in steel sleeve 1 circumferential wall, after some circulations, in stake holes, sediment constantly reduces, clear hole is terminated, extract hole device clearly, transfer cable wire 23, filter screen 3 bottom, dregs draws off.
As shown in Figure 3, Compressed Gas pipeline 7 or foam squeeze pipeline 8 and adopt welding or bolted mode to be fixed on steel sleeve 1 inwall, Compressed Gas exports 16 by Cemented filling to Compressed Gas, Compressed Gas is (foaming agent pipeline is not containing shunting body 18) after gas distribution body 18, gas dispersion ejects, and sheet rubber 13 is opened by rotating bolt 15 effect; When after closedown gas valve, act on through spring 12, sheet rubber 13 closes automatically, prevents sediment from entering pipeline; Foam squeezes and squeezes pipe outlet without gas distribution body 18 by Cemented filling to foaming agent outlet 17(foam, and all the other components are with Compressed Gas pipeline), sprayed in mixing material by outlet.
Be illustrated in figure 4 Compressed Gas pipeline and foam squeezes pipeline plan-position arrangement diagram, by known as shown in the figure, Compressed Gas pipeline lays four, and foam squeezes pipeline and lays two.Duct bottom have pipe outlet give prominence to, bottom pipe outlet with steel sleeve bottom on same level position.
As shown in Figure 5, two half elliptic filter screens 3 are fixed on circular inserting rod 21 by filter screen rotating bolt 22, and filter screen 3 can be rotated around circular inserting rod 21 by rotating bolt 22; When starting to collect sediment, filter screen 3 is fixed on screens device 19, when screens device upwards swing exceed certain angle time, spring 12 can prevent screens device to be close to steel sleeve; When sludge collection completes, transfer cable wire 23, filter screen 3 rotates to the bottom by rotating bolt 22 around circular inserting rod 21, and sediment draws off.
As shown in Figure 6 and Figure 7, be respectively screens device facade and sectional drawing, screens device 19 is fixed on steel sleeve 1 by fixed axis 25, and filter screen is positioned on screens device, and the spring be fixed on steel sleeve can limit screens device upwards swings.
Revolve with biography and dig stake holes and unite compared with the device of clear hole, clear hole device self can form self-loopa, and clear hole device does not limit by the degree of depth, can in deep hole clear hole; Set up Compressed Gas pipeline bottom the device of clear hole, bottom sediment can be formed suspended mixture zoarium under gas effect, be conducive to scarfing cinder, scarfing cinder is more thorough; Foaming agent plays lubrication to sediment, reduces and takes out slag resistance; Clear hole device adopts self-circulation system, can reduce clear hole number of times, realizes disposablely completing hole clearly; Clear hole device circulatory mediator can be water or mud, when adopting water as circulatory mediator, and environmental protection, mud-less pollution.In a word, utilize and revolve that to dig hole Qi Qing hole clearly more thorough, reduce tradition and revolve and dig hole Qi Qing hole number of times clearly, save the construction period, when using water as circulatory mediator, environmental protection.
It should be noted that in addition, each concrete technical characteristic and preferred embodiment described in above-mentioned detailed description of the invention, can be undertaken combining and equivalents by any suitable mode, these all belong to protection scope of the present invention.
