In order to buffer the vertical rod 2, a second pressure spring 17 is sleeved on the vertical rod 2, one end of the second pressure spring 17 is fixed on the inner upper end surface of the circular tube 1, and the other end of the second pressure spring 17 is fixed on the vertical rod 2.

For electric putter 12's installation and the constraint to pipe 1, the circumference equipartition has a mounting groove 18 of a plurality of electric putter 12 on disc 11, and electric putter 12 installs in mounting groove 18, and electric putter 12 stretches out to serve and is equipped with cambered surface and the pipe 1 excircle towards the arc 19 of laminating mutually, and the inboard of arc 19 is equipped with the rubber packing piece.

In order to realize the installation of the pressure sensing switch 16, each rope 9 is divided into two sections and is connected into a complete rope 9 through the pressure sensing switch 16.

In order to realize the installation of the indicator light 15, a sleeve 20 is coaxially fixed at the lower end of the pressure plate 14, the indicator lights 15 are circumferentially and uniformly distributed on the sleeve 20, and the diameter of the pressure plate 14 is larger than that of a circle-like structure formed by the indicator lights 15.

The specific working process of the invention is as follows: in the initial state of the device, the vertical rod 2 is pressed downwards to enable the fixed disk 3 to drive the plurality of ropes 9 to tighten, the tightened ropes 9 drive the sliding block 8 to move upwards and compress the first pressure spring 10 in the process, meanwhile, the sliding block 8 moves upwards to drive the flat steel sticks 5 to move upwards, the flat steel sticks 5 are retracted into the circular pipe 1 under the guiding action of the guide pipe 4, the circular pipe 1 in the state is pressed towards the underground of a pile foundation to enable the tip of the circular pipe 1 to move downwards for a certain distance, the vertical rod 2 is loosened, the flat steel sticks 5 extend outwards under the action of the guide pipe 4 under the resetting action of the first pressure spring 10, the extending ends are inserted into soil around the circumference, the diameter of a similar circular structure formed by the flat steel sticks 5 is larger than that of a flood control pile to be inserted into the pile foundation, after the electric push rod 12 extends, and the disc 11 is sleeved on the part of the circular pipe 1 above the ground, meanwhile, the lower end face of the disc 11 is horizontal to the ground and contacts with the ground, and after the installation is finished, the extending end of the electric push rod 12 extends out, so that the arc-shaped plate 19 contacts with and extrudes the outer circular face of the circular tube 1.

At the moment, striking on the pressure plate 14 is realized through manual holding and matching hammering operation, in the process, the outer circular surface of the circular tube 1 is contacted and extruded by the arc-shaped plate 19 driven by the electric push rod 12, at the moment, the circular tube 1 is fixed, the vertical rod 2 moves downwards and realizes contraction of the rope 9, the rope 9 contracts to drive the sliding block 8 to move upwards and drive the recovery of the flat steel sticks 5, in the process, the hammering force is continued after the flat steel sticks 5 are completely recovered, so that the lower end surface of the sleeve 20 is contacted and extruded with the driving switch 13, the driving switch 13 is extruded to realize retraction of the extending end of the electric push rod 12, at the moment, the hammering force is continuously acted on the circular tube 1 to realize downward movement of the circular tube 1, the hammering force is separated from the hammer pressure plate 14 after hammering is completed, at the vertical rod 2 moves upwards in a resetting way under the resetting action of the second pressure spring 17 and the first pressure spring 10, and the first pressure spring 10 is not bound any more, the pressure spring is released by the power that the hammering was held and pushes away 5 crowds of band steel, and stretching out of 5 is signed to this in-process at the guide effect of stand pipe 4 realization band steel, can withdraw the back with band steel when hammering once more and hammer 1 downwards at the realization pipe, and reciprocating circulation finally drives 1 assigned position of pipe downwards to accomplish stretching out of many times steel band in this in-process, realize the detection of multilayer soil layer debris.

When the flat bamboo slips of steel met debris, rope 9 loosened but the flat bamboo slips of steel stretched out by blockking this moment, rope 9 can not be by the flat bamboo slips auxiliary stretching of the steel that stretches out, pressure-sensitive switch 16 at this moment opens the position that the pilot lamp 15 of corresponding position lights up and judges the position of stone, supplementary subsequent excavation, if the flat bamboo slips of steel can stretch out when rope 9 loosens all the time, then rope 9 all is in tensile state at whole in-process, pressure-sensitive switch 16 closes all the time, pilot lamp 15 remains the state of not lighting all the time, prove that there is not debris below this pile foundation position can carry out the pile driving operation of flood control stake.

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

1. this device can outwards stretch out through the setting of a hollow pipe 1 in pipe 1 and sign 5, earlier realize that flat bar signs 5's retraction when hammering pressure disk 14, realize the lower of pipe 1 again and visit, pipe 1 visits the completion back down, flat bar signs 5 and resets and stretches out, carry out the detection of a major diameter to this region, thereby get rid of the hard thing of this regional stone, this device adopts the mode of intermittent type hammering, can effectually carry out the effect that down-drive also can realize layering detection to pipe 1, make whole stone detection process more high-efficient laborsaving.

2. This device passes through pilot lamp 15 and pressure sensitive switch 16's setting 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. Electric putter 12 provides a supporting role for pipe 1 in this device for the band steel is signed 5 and is just can realize the lower of pipe 1 after being retracted completely, and this in-process guarantees that pipe 1 and band steel are signed 5 and have a seesaw order, prevents that band steel is signed 5 and is damaged.
