Technical scheme of the present invention is as follows: it comprises lifting rope, hanger; It is characterized in that: it also comprises weighted rod, backplate, probe, guide plate, spring leaf, one-way slabs, weighted rod is the cylindricality weight, the top of weighted rod is provided with hanger, be that lifting rope is arranged on the hanger, the lower end of weighted rod is provided with backplate, the backplate below is provided with probe, the bottom of probe is a pyramidal structure, the vertex of a cone down, diameter at the bottom of the awl of pyramidal structure is greater than the diameter of probe, above the conical structure of probe, be provided with one-way slabs, be fixed with guide plate on the one-way slabs, the junction of one-way slabs and guide plate is fixed with spring leaf, described one-way slabs, spring leaf, respectively be provided with circular hole on the guide plate, probe is with one-way slabs outward successively, spring leaf, there is certain angle in guide plate between spring leaf and the one-way slabs.
The present invention has following advantage: 1 is simple in structure, and dismounting is easy to maintenance; 2 is easy to use, only needs shirtsleeve operation, just can control the present invention; 3 is practical, can quantize to detect to sediment thickness.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Label declaration: 1 lifting rope, 2 hangers, 3, weighted rod, 4 backplates, 5 probes, 6 guide plates, 7 spring leafs, 8 one-way slabs.
Embodiment
Below in conjunction with accompanying drawing the present invention is specifically described:
As shown in Figure 1, the present invention includes lifting rope 1, hanger 2, weighted rod 3, backplate 4, probe 5, guide plate 6, spring leaf 7, one-way slabs 8, weighted rod 3 is the cylindricality weight of cylindrical or other shape, weight by weighted rod itself realizes that the present invention moves vertically downward, the top circle centre position of weighted rod is provided with hanger 2, be that lifting rope 1 is arranged on the hanger, the lower end of weighted rod is provided with backplate 4, the backplate below is provided with probe 5, the bottom of probe is a pyramidal structure, the vertex of a cone of tapered structure down, resistance in the time of can reducing probe like this and contact with pile bottom sediment, probe still can be moved downward behind the pile bottom sediment, a harder soil property at the bottom of touching and stopping under the effect of weighted rod gravity in contact.Diameter at the bottom of the awl of pyramidal structure is greater than the diameter of probe, above the conical structure of probe, be provided with one-way slabs 8, be fixed with guide plate 6 on the one-way slabs, guide plate connects and composes inverted "L" shaped by leveling board and vertical plate, directly fixedly connected with one-way slabs in the bottom of vertical plate, the leveling board of guide plate is provided with circular hole.The junction of one-way slabs and guide plate is fixed with spring leaf 7, on described one-way slabs, spring leaf, guide plate, respectively be provided with circular hole, the circular hole of guide plate is arranged on horizontal direction, probe passes circular hole set on one-way slabs, spring leaf, the guide plate successively, has certain angle between spring leaf and the one-way slabs.One-way slabs realizes one-way movement by the spring leaf that its top is provided with.Weighted rod is a cylindrical structural, and one-way slabs and backplate are circular slab, and their center of circle is on same axis.The slightly larger in diameter of the circular hole on the one-way slabs so promptly can reduce the friction force between one-way slabs and the probe in the diameter of probe, and the diameter of the circular hole on the one-way slabs is slightly less than the cone bottom diameter of pyramidal structure, can prevent that like this one-way slabs from coming off from probe.The diameter of backplate is greater than the diameter of one-way slabs; by backplate is set; can protect the one-way slabs that is moving downward; when preventing that detector of the present invention from moving downward in bored concrete pile; one-way slabs is because of running into the pile lining of bored concrete pile; and take place, thereby testing result is caused a deviation to top offset.
Principle of work is as follows: because spring leaf tilt to place, contact between spring leaf and the probe; When probe contact pile bottom sediment, be subjected to the effect of weighted rod weight, probe continues to move down in sediment; Drive is positioned at one-way slabs on the sediment etc. and moves down synchronously, when one-way slabs is displaced downwardly to the upper surface of sediment, because the surface area ratio of one-way slabs is bigger, so one-way slabs rests on the pile bottom sediment surface, sediment produces power upwards to one-way slabs, and one-way slabs provides thrust upwards to an end that is attached thereto the spring leaf that connects, and makes the horizontal deformation of spring leaf trend, contacting between spring leaf and the probe reduces, thereby helps spring leaf and one-way slabs moves upward with respect to probe.
At the bottom of probe is visited stake, hard soil layer at the bottom of running into, promptly stop to move down, this moment is when upwards reclaiming detector of the present invention, be subjected to the influence of one-way slabs weight, make an end of the spring leaf that is connected with one-way slabs produce the tendency that moves down, and force the spring leaf degree of tilt to become big, thereby spring leaf is stuck on the probe tightly and can't does downward moving, realize the one-way slabs move mode that only one can manage to scramble up but find it difficult to get down, realize measuring the sediment thickness purpose with respect to probe.
As the case may be, can outside the probe between spring leaf and the one-way slabs, back-moving spring be set.By back-moving spring, increase the elasticity of spring leaf.
When using detector of the present invention, when probe contact pile bottom sediment, detector of the present invention need be improved slightly, loosen lifting rope afterwards, make detector of the present invention produce downward impulse force, and repeatedly carry out this operation, guarantee that the probe conical structure arrives the stake firm part at the end.After measuring one group of data, one-way slabs is manually returned to the lower end of probe, repeat again in the sediment of former measurement point periphery, to measure, carrying out after many groups measure, can roughly draw the maximum ga(u)ge of pile bottom sediment, this thickness promptly is required data.
