Abstract
A sand pipe detector is used for measuring the bottom elevation of a sand pile sleeve penetrating into the soil layer, is connected with the sand pile construction sleeve, and comprises a group of measuring cables and a group of pulleys, wherein the measuring cables are connected to the top end of the sleeve and wound around the pulleys, a coder is coaxially mounted on one pulley and is connected with a programmable logic controller (PLC), and a balancing weight is connected with the tail ends of the measuring cables. The group of independent measuring steel cables is adopted and moves downwards with the sleeve when the sleeve penetrates into the soil layer, so as to drive the pulley coaxially mounted with the coder to rotate. Therefore, the gathering and releasing distances of the measuring cables can be obtained through the coder and the PLC, which ensures that the relative height of the sand pile sleeve can be acquired. The utility model has the advantages of simple structure, convenience in operation, and high measuring precision.
Description
Technical field
The utility model relates to the sandy pile construction field, especially relates to the sandpipe detector of the bottom absolute altitude of measuring sand pile sleeve pipe injection soil layer.
Background technology
The construction technology of common sand pile is under the vibration effect of bobbing machine, and the sand pile sleeve pipe is squeezed into the projected depth of regulation, after the sand pile sleeve pipe buries, drops into sand again, and sediment outflow just becomes sand pile in soil.This construction technology treatment effect is better, makes stake and inter-pile soil form composite foundation preferably, has improved bearing capacity of foundation soil, has prevented sand liquefaction, has increased the resistance to overturning of weak foundation soil.
Sand compaction pile is a kind of ground stabilization new technology under water, and it is by vibratory equipment and tube chamber supercharging device sand to be forced to be pressed under water in the soft foundation on the sand pile ship, through vibration pipe-drawing, return, compacted hole enlargement, form sand compaction pile.By the displacement of sand compaction pile, compacted, drainage, can increase foundation strength, accelerate ground consolidation, reduce the works sedimentation, improve the anti-liquefying power of ground.The scope of application of sand compaction pile is extensive under water, can be applicable to the ground stabilization of nearly all soil properties such as sandy soil, cohesive soil, organic soil is handled.Compare the density height of sand compaction pile pile body with common sand pile, the replacement ratio of reinforcing can reach 60～70%.Characteristics such as sand compaction pile has short construction period under water, consolidation effect is obvious, and the operation controllability is good, the advantage uniqueness is highly suitable for the ground base enforcement of engineerings such as off-lying sea man-made island, mole, shore protection, harbour.
In the sand compaction pile construction operation, the bottom absolute altitude of sand pile sleeve pipe injection soil layer is important construction parameter.
The utility model content
The bottom absolute altitude of sand pile sleeve pipe injection soil layer when measuring sandy pile construction, the utility model provides a kind of sandpipe detector.
The technical scheme that its technical problem that solves the utility model adopts is,
The sandpipe detector, be connected in the sand pile sleeve pipe, described sandpipe detector comprises measuring cable, pulley, balancing weight, encoder and programmable logic controller (PLC), measuring cable is connected in the top of sand pile sleeve pipe, walk around one group of pulley, described pulley is fixed pulley, coaxial installation one encoder on one of them pulley, encoder connects a programmable logic controller, and the end of measuring cable is connected with balancing weight.
The beneficial effects of the utility model are, used one group independently to measure wirerope, in the process of sand pile sleeve pipe injection soil layer, measuring cable drives with the coaxial mounted pulley of encoder and rotates along with the sand pile sleeve pipe moves downward, and the retractable distance of measuring cable just can obtain by encoder and PLC, thereby learn the relative altitude of sand pile sleeve pipe, it is simple in structure, simple operation, certainty of measurement height.
Description of drawings
Fig. 1 is the measuring principle figure of sandpipe detector;
Among the figure, 11. Duo winches, 12. main push-towing ropes, 13. pulleys, 14. pulleys, 20. sleeve pipes, 31. balancing weights, 32. pulleys, 33. pulleys, 34. pulleys, 35. measuring cables, 36. pulleys, 37. pulleys, 38. encoders, 39.PLC.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, measuring cable 35 is connected in the top of sleeve pipe 20, and measuring cable 35 is walked around pulley 37, pulley 36, pulley 34, pulley 33 and pulley 32 successively, and all pulleys are fixed pulley, the coaxial encoder 38 that is equipped with on its middle pulley 34, encoder 38 is connected with PLC 39.The end of measuring cable 35 also is connected with balancing weight 31.
Be connected with main push-towing rope 12 on the Duo winch 11, main push-towing rope 12 is walked around the top that is connected to sleeve pipe 20 behind pulley 13 and the pulley 14, and Duo winch 11 is by taking up or loosening the lifting that main push-towing rope 12 is controlled sleeve pipe 20.
In the process of sleeve pipe 20 injection soil layers, measuring cable 35 moves downward, and drives with encoder 38 coaxial mounted pulleys 34 to rotate, and the retractable distance of measuring cable 35 just can obtain by encoder 38 and PLC39.The major parameter of system works is origin position and encoder step long value.Therefore measuring cable can cause the measured deviation of origin position by in the process of pulley skidding taking place, and can reduce the possibility that measuring cable skids by the weight of adjusting balancing weight 31.
The utility model has used one group independently to measure wirerope, in the process of sleeve pipe injection soil layer, measuring cable is along with sleeve pipe moves downward, drive with the coaxial mounted pulley of encoder and rotate, the retractable distance of measuring cable just can obtain by encoder and PLC, it is simple in structure, simple operation, certainty of measurement height.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
