When the steel flat stick met debris, this moment corresponded the position flat steel stick 5 and can not stretch out, along with reciprocating screw nut 3 move down, first pressure spring 10 pressure crescent, the pressure sensor switch got the electricity and made and correspond pilot lamp 15 and light to judge the position of stone, supplementary subsequent excavation, if at whole hammering, pilot lamp 15 remains the not bright state throughout, it can carry out the pile driving operation of flood control stake to prove to have debris below this pile foundation position.

Compared with the traditional equipment, the device has the following advantages:

1. this device can outwards stretch out ribbon-steel stick 5 through a hollow pipe 1 sets up in pipe 1, contact motor drive switch 14 earlier at the hammering in-process and realize the circular telegram and make a time delay under the effect of delay timer and handle, this time delay in-process realizes the hammer and beats pipe 1 downwards, this hammering process speed is very fast, thereby accomplish reciprocal stretching out of accomplishing ribbon-steel stick 5 of reciprocal lead screw nut 3's upper and lower reciprocating motion of motor action realization back, carry out the detection of a major diameter to this region, thereby get rid of the hard thing of stone in this region, can effectually carry out the effect that the downward drive also can realize the layering and survey to pipe 1, make whole stone detecting process more high-efficient laborsaving.

2. This device passes through pilot lamp 15 and the setting of forced induction switch 9 for when a certain band steel is signed 5 and is met hard thing and can't reset, the band steel of other positions is signed 5 and is not influenced and reset, and this can effectually demonstrate the position relation of this regional stone, only need carry out the simple adjustment of position when carrying out flood control pile and can realize the pile of this regional flood control pile, avoids the waste of the manpower and materials that the stone excavation brought.

3. This device adopts the mode of intermittent type hammering, hits the time of beating short relatively, and interval time is long relatively, consequently gives reciprocating motion and provides sufficient time for whole device all has reasonable operating time beating with the in-process of surveying, makes the device more high-efficient reasonable.
