Detailed description of the invention
Accompanying drawings 1, the utility model is made up of the feeler lever 8 be arranged in sleeve pipe 2, and feeler lever 8 is threaded by guiding feeler lever 7, reamer 6 and probe 5 successively and forms; Sleeve pipe 2 to be threaded with shoe 4 by union 3 and to form, and sleeve pipe 2 one end is provided with the flange socket 1 be threaded.
Accompanying drawings 2, described reamer 6 is made up of the sliding sleeve 62 be sleeved on connecting rod 61, and sliding sleeve 62 and connecting rod 61 are for being slidably connected; Described connecting rod 61 is provided with the adapter of seam 66 for one end, which is provided with upper and lower and symmetrically arranged from sucker 64; Describedly be provided with radial seal groove and sealing ring 63 from sucker 64 both sides; Described sliding sleeve 62 is the middle drum shape tilted to both sides, is provided with upper and lower and symmetrically arranged annular compartment 65 in it.
Accompanying drawings 3, described feeler lever 8 is threaded by guiding feeler lever 7, reamer 6 and probe 5 successively and forms, reamer 6 is made up of the sliding sleeve 62 being sleeved on connecting rod 61, one end of connecting rod 61 is provided with seam 66, and sliding sleeve 62 is on connecting rod 61 and be limited to reamer 6 and slide between the guiding link of feeler lever 7 and seam 66; Described sliding sleeve 62 slides on connecting rod 61, its annular compartment 65 be one_to_one corresponding from sucker 64; Long 0.5 ~ 1 meter of the every root of described guiding feeler lever 7, the convex tendon 71 of uniform four axis on its excircle, the setting of convex tendon 71 adds the support force of guiding feeler lever 7, well prevents the bending of feeler lever 8.
Accompanying drawings 4, described sleeve pipe 2 to be threaded with shoe 4 by union 3 and to form, and sleeve pipe 2 one end is provided with flange socket 1, and flange socket 1 and sleeve pipe 2 are for being threaded; Described sleeve pipe 2 arranges a union 3 every 2 ~ 3 meters; Be provided with support ring 31 in described union 3, support ring 31 has the strong point after making feeler lever 8 stressed, effectively prevents flexural deformation and the fracture of feeler lever 8.
The utility model is work like this: will connect guiding feeler lever 7 successively, the feeler lever 8 of reamer 6 and probe 5 penetrates in the sleeve pipe 2 that is connected with shoe 4 by union 3, after the utility model being pressed into soil layer by static pressure equipment, sliding sleeve 62 on self-priming reamer 6 moves, the slurries utilizing the pressure differential of ground and subterranean depth to prepare are by the annular compartment 65 flowing to its correspondence from sucker 64 on connecting rod 61 top, the slurries entered in annular compartment 65 are flowed out by the gap between sliding sleeve 62 and connecting rod 61, enter in quiet inspecting hole and play protection hole wall, prevent the appearance of shrinkage cavity and collapse hole state, to increase the lubrication of feeler lever 8 and hole wall, play the frictional resistance reducing feeler lever 8 circumferential surface, the penetration capability of raising equipment, thus make feeler lever 8 reach the degree of depth and the Ps value of designing requirement.Convex tendon 71 on guiding feeler lever 7 effectively adds the support force of feeler lever 8, well prevents the bending of feeler lever 8.When feeler lever 8 pulls out; the seam 66 that sliding sleeve 62 moves down into connecting rod 61 is thereupon kept out; slurries flowing out from the annular compartment 65 of sucker 64 by its correspondence by connecting rod 61 top, plays protection probe 5 to reduce vacuum state (Negative Pressure Difference), makes feeler lever 8 can extract soil layer faster.
More than just be further described the utility model, and be not used to limit this patent, all be the utility model equivalence enforcement, within the right that all should be contained in this patent.
