Background technology
CFG(Cement Flying-ash Gravel) stake means CFG, and material of body of a pile is stirred the compound that forms by cement, flyash, rubble, aggregate chips or sand, water and additive.What pile making method application at present was maximum is compound casting method for forming column in the long auger pipe.
In recent years, the CFG stake is widely used in engineering foundation.In the large tracts of land ground is handled, when the compound casting method for forming column is constructed in the long auger pipe is adopted in the CFG stake, next stake machine of generalized case is equipped with a towed concrete pump, generator when external power source (no) and some concrete tanks, constructs continuously round the clock.The groundwater increment of one pile is got the average of a tank car or several tank car compounds more, is difficult to accurately measure the actual groundwater increment of a pile, also can't determine the groundwater increment of pile body different depth, and pile quality can only rely on the sampling Detection in later stage to carry out.And the piling of CFG stake machine the time also exists drilling depth accurately not grasp and the soft or hard degree on stratum quantizes, carries and boring and the pumping problems such as the broken pile undergauge occur that do not match.
The utility model content
The technical problems to be solved in the utility model provides a kind of CFG pile driving construction parameter self-recording device that can control effectively to pile quality.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of CFG pile driving construction parameter self-recording device, and its key is that it comprises depth transducer, current sensor, temperature sensor, concrete pump flow sensor, scrambler testing circuit, first A/D converter, second A/D converter, counting circuit, single chip circuit and display screen; The output terminal of described depth transducer, current sensor, temperature sensor and concrete pump flow sensor is the respective input of encoded device testing circuit, first A/D converter, second A/D converter and counting circuit order sheet machine circuit respectively; The input end of the output termination display screen of described single chip circuit.
Adopt the beneficial effect that technique scheme produced to be: the utility model can at length write down each parameter variation in the work progress, can in CFG pile driving construction process, monitor in real time pile quality, can in time estimate its pile quality, accurately reflect the actual amount of pouring in the filling process, and can obtain the penetration rate of different depth really, the amount of pouring into, indexs such as fullness coefficient, reflection and come keyhole speed better by operating personnel, put forward key links such as pipe speed, avoid rig occurring and waving because drill speed is too fast, problems such as inclined to one side hole; Avoid defectives such as undergauge, folder mud occurring owing to put forward the pipe excessive velocities.The utility model can reduce on-the-spot guard personnel, saves executive cost, improves construction quality, has precision height, good reliability, simple, convenient and practical, advantages such as cost performance is high and instrument is easy to carry, the convenient installation of peripheral sensor.
The utility model can solve following problem: the degree of depth that (1), record creep into, and prevent to perform workman's brill and just propose the brill perfusion less than the degree of depth, do not reach designing requirement; Electric current when (2), record creeps into, when long-spiral drilling machine creeps into, the certain relation of soft or hard degree on the stratum that its current value contacts with drill bit, the stratum is hard more, it is big more that it creeps into electric current, can know more intuitively that stratum geology changes, can know indirectly whether the stake point has been put on the stratum of design; (3), after creeping on projected depth or the design stratum, carry and bore the pumping concrete, when carrying brill, whenever carry and bore 1 meter, the pumping number of times of record concrete pump, calculate the concrete amount of pumping simultaneously, and compare with every meter concrete demand in theory, if the pumpage that adds up, illustrates that carrying drilling speed spends soon less than the concrete demand that adds up, the concrete quantity of pumping can not satisfy design flow, formed emptying aperture, broken pile just, at this time self-recording device can be reported to the police to the operator in buzzing, slows down and carries the drilling speed degree or accelerate the concrete rate of pumping; (4), because of CFG stake stabilization zone mostly is weak mud geology, when pile, because of the pressure of mud around the concrete pressure ratio wants big, a reaming (thicker than design stake footpath) may appear in pile, the situation that necking down (thinner) perhaps occur than design stake footpath, in the past because can not these construction parameters of real time record, and can't analyze, the concrete consumption that every meter of self-recording device record is arranged, in the later stage one batch data is carried out aftertreatment, just can analyze and on that stratum, occur reaming and necking down easily, can when constructing operation, adjust the appearance that construction parameter is avoided necking down as far as possible.
