Abstract
The utility model relates to the field of construction detecting equipment, in particular to a dredging device for a high-pressure water jet detector tube. The problem that because the detector tube is blocked, ultrasonic method detection can not be performed is solved. The dredging device for the high-pressure water jet detector tube comprises a high-pressure plunger pump, a high-pressure rubber hose, a foot valve, a high-pressure hose and a nozzle, the high-pressure rubber hose is connected to the high-pressure plunger pump and connected with the foot valve, and the nozzle is arranged on the high-pressure hose. The dredging device for the high-pressure water jet detector tube is simple in structure, low in technical labor requirements and high in efficiency and success rate, and the time needed for dredging each pipe is short.
Description
Technical field
The utility model relates to construction checkout equipment field, specifically a kind of high-pressure water jet detector tube dredger.
Background technology
Aspect the quality testing of pile foundation entity, the hyperacoustic ratio of detector tube is more and more higher, and detector tube bury underground determined supercritical ultrasonics technology detect can carry out smoothly, how to strengthen detector tube quality control also more and more important.And in work progress, usually there is detector tube plugging phenomenon, thus bring difficulty to follow-up pile foundation testing, affect construction quality and progress.
Summary of the invention
The utility model, in order to solve because detector tube plugging causes the problem that cannot carry out supercritical ultrasonics technology detection, provides a kind of high-pressure water jet detector tube dredger especially.
The utility model is taked following technical scheme: a kind of high-pressure water jet detector tube dredger, comprise high-pressure plunger pump, high-pressure rubber pipe, foot valve, high-pressure hose and shower nozzle, on high-pressure plunger pump, be connected with high-pressure rubber pipe, high-pressure rubber pipe is connected with foot valve, foot valve is connected with high-pressure hose, and high-pressure hose is provided with shower nozzle.
Described shower nozzle is that front end is provided with four spouts, and rear end is provided with six spouts, shower nozzle diameter 2cm, spout aperture 1-2mm.
So-called high-pressure water jet, that ordinary tap water is pressurized to hundreds of and even thousands of atmospheric pressures by high-pressure pump, then by special nozzle (aperture only has 1-2 millimeter), with the concentrated current of one energy height of high speed (200-500 meter per second) ejection.This one one weep has huge blow energy as pellet, and it can carry out steel plate cutting, cast cleaning, metal-derusting, more can remove salt, alkali, dirt and the various tamper of tube wall.The current that utilize this strand to have huge energy clean and are Cleaning by High Pressure Water Jet.
Compared with prior art, the utility model is simple in structure, and technique labour demand is little, and efficiency is high, and success rate is high, and required time every pipe dredging time is short.

Detailed description of the invention
As shown in Figure 1, a kind of high-pressure water jet detector tube dredger, comprise high-pressure plunger pump 1, high-pressure rubber pipe 2, foot valve 3, high-pressure hose 4 and shower nozzle 5, on high-pressure plunger pump 1, be connected with high-pressure rubber pipe 2, high-pressure rubber pipe 2 is connected with foot valve 3, foot valve 3 is connected with high-pressure hose 4, and high-pressure hose 4 is provided with shower nozzle 5.
Described shower nozzle 5 is provided with four spouts for front end, and rear end is provided with six spouts, shower nozzle diameter 2cm, spout aperture 1-2mm.
High-pressure plunger pump is diesel type, maximum pressure 90MPa, and per hour factor is in 15L/h left and right.Its principle is that diesel engine drives plunger to move reciprocatingly, the suction metering valve switch with hydrodynamic pressure end thus, and when plunger back moves, inlet valve is opened, and dump valve cuts out, and low-pressure water enters, when plunger stretching routine, suction valve closure, dump valve is opened, and produces water under high pressure.
High-pressure rubber pipe is connected with plunger displacement pump and foot valve, and high-pressure hose is connected with shower nozzle and foot valve, and to bear maximum pressure be 140MPa.Foot valve, as control valve, can be controlled water under high pressure pressure, and convenient dredging is controlled.
After the utility model connects, start high-pressure pump, adjust water pressure in 40MPa left and right by control valve, after pressure stability, be progressively increased to again 70MPa, high-pressure nozzle is sent into detector tube, step on foot valve, water under high pressure is delivered to shower nozzle.Because the nozzle type adopting is self-advancing type shower nozzle, stuck for preventing shower nozzle, in dredging process, to control from entering speed, can adopt the measure lifting up and down.
Incipient stage, because nothing in detector tube is stopped up, the water returning out from the mouth of pipe is clear water, and to blocking position, the mouth of pipe returns out sewage, and shower nozzle from driving, is smashed tamper and returns out from the mouth of pipe downwards.If now shower nozzle does not down tunnel, illustrate that sprinkler pressure is inadequate, should continue pressurization.
