The radar wave level meter is connected with a programmable logical controller through a tensile signal cable; the programmable logical controller is connected to a computer; a level meter protection device is arranged on the radar wave level meter and comprises a protection cover; and an automatic cleaning device is arranged on the protection cover. Due to the adoption of the radar wave level meter, the position information of a sand surface can be obtained through the time difference microwave transmission and microwave receiving; and when a sand pile sleeve is under the severe environments of darkness and vibration, the microwave transmission is not affected, so that the sand surface detector can normally work. Meanwhile, the sand surface detector has the advantages of quick measurement speed and higher precision and completely meets the measurement requirements the sand surface in the construction of a sand pile.
Description
Technical field
The utility model relates to the sandy pile construction field, especially relates to being used to detect the sand face detector that the sand material level is put in the sand pile sleeve pipe.
Background technology
The construction of sand compaction pile under water 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, can effectively improve the anti-liquefying power of ground, reduce the works sedimentation.The scope of application of sand compaction pile is extensive under water, can be applicable to the foundation stabilization of nearly all soil properties such as sandy soil, cohesive soil, organic soil is handled.
Sand face detector is the key equipment that sand compaction pile can be constructed.Sandy pile construction mainly relied on control pipe casing pipe-pulling speed and added enough sand material and guaranteed construction quality in the past.Owing in the tube drawing process, can't know the actual conditions of sand material drain sleeve in the sleeve pipe, exist and irritate the shortcoming that sand coarse aggregate ratio can not get guaranteeing in the work progress, be prone to that the sand pile local diameter is dwindled even defective such as broken pile, the sandy pile construction quality can not get guaranteeing.For guaranteeing the sand compaction pile quality, must irritate sand coarse aggregate ratio and the achievement of reflection hole enlargement in real time in the control work progress, the positional information that the sand material is provided rapidly and accurately is the function that sand face detector should possess.
For the measurement of material position in the container, on principle, be divided into two kinds of methods of contact and non-contact measurement.Experiment shows that it is slower to use the interior sand material level of contact sand face detector detection sand pile sleeve pipe to put its measuring speed, break down easily, and its measuring error also is very important.
Difference on the surveying instrument that mainly is respectively to use of non-contact measurement, industrial widely used non-contact measurement instrument mainly contains at present: laser range finder and radar wave level meter.Experiment showed, that laser range finder can not receive reflecting light under the construction environment of the long and narrow dark of sand pile sleeve pipe, vibration, so can not use.
The utility model content
In sand pile sleeve pipe work progress, need to obtain in real time the positional information of sand material, in order to solve the problem that contact stadimeter speed is slow, error is big, the sand face detector that the utility model provides accurate fast detecting sand material level to put.
The technical scheme that its technical matters that solves the utility model adopts is,
Sand face detector includes the radar wave level meter, and the radar wave level meter is connected with programmable logic controller (PLC) by the tension signal cable, and programmable logic controller (PLC) is connected to computing machine.The radar wave level meter is installed on sandy pile construction sleeve pipe top, microwave pulse is launched downwards by the antenna system of radar wave level meter, level meter picks up counting simultaneously, arrive upwards reflection behind the sand material of sleeve pipe bottom with the microwave of light velocity propagation, after microwave reflection is received by antenna system, timing stops, and the travel-time by microwave can calculate its propagation distance.After the radar wave level meter will be measured range data that the sand face obtains and transfer digital signal to, signal is transferred to Computer Processing by the tension signal cable.
On the described radar wave level meter level meter protective device is arranged, the level meter protective device comprises a protective cover, and protective cover is provided with automatic cleaning apparatus.The level meter protective device completely cuts off sleeve pipe compressed air, water, the sand adverse effect to the radar wave level meter; long-pending sand, ponding on the automatic cleaning apparatus cleaning protective cover; guarantee that the electromagnetic wave that level meter sends can arrive the sand face, avoid the sand material on protective device accumulation and the measurement stability problem that causes.
The radar wave level meter adopts the very low extremely short microwave pulse of energy by antenna system emission and reception.Microwave moves with the light velocity, can convert thing position signal to its working time by electronic unit, can guarantee the utmost point stable and accurate measurement in the short time by a kind of special time extension method, the input pod size, distance value can be converted to the signal that is directly proportional with the thing position, generally be used for the non-contact type article position measuring under the rugged surroundings.
The beneficial effects of the utility model are, owing to adopted the radar wave level meter, utilize microwave emission and the mistiming that the receives face positional information of to shake out, under the rugged surroundings of sand pile sleeve pipe dark, vibration, microwave transmission is unaffected, sand face detector energy operate as normal, simultaneously, its measuring speed is fast, and precision is higher, satisfies the sand planar survey requirement in the sandy pile construction fully.
