Abstract

The utility model discloses a multi-pilehead cement-soil mixing pile construction quality monitoring recorder, which is characterized in that by utilizing a single chip technology and sampling parameters of the grout amount of different piles on the same pile machine, the digging depth of the piles, the slurry density poured in the pile body and the construction technology, corresponding grout amount, depth and density during the process of constructing the cement-soil mixing pile are automatically sampled into the single-chip, being processed and output in real time through a simulation light-pole, digital display and a printer, then the pile-constructing data are reflected visually, which provides data basis for the construction quality, meanwhile the equipment parameter of the pile machine set by software ensures measuring accuracy and commonality of peripheral devices.

Description

Many pile crowns cement-soil stirring pile construction quality monitoring, recording instrument

Technical field

The utility model relates to a kind of cement-soil stirring pile construction quality-monitoring of normal use in the building trade subgrade is handled, and especially to the enforcement monitoring of many pile crowns agitation pile, writes down its grouting amount, digs data instrument such as the degree of depth, slip casting density down.

Background technology

At present, existing monitoring and recording instrument is to adopt single chip circuit or PLC circuit to monitor the grouting amount of single pile crown, measure grouting amount with electromagnetic flowmeter by the A/D change-over circuit, measure driving depth with reversible photoelectric encoder by mechanical driving device, through the processing of single-chip microcomputer or PLC, print and demonstration grouting amount and driving depth.But: (1) now the cement-soil mixing pile machine that uses of China is progressively developed to many pile crowns (double end, three, five) direction by a pile crown, and the monitor of single pile crown can not satisfy the needs of updating the equipment; (2) density of the slip casting of existing recorded instrument measurement is separated, and measures at the agitator place, with instrument or manual densimeter measurement, can not reflect the cement slurry density that injects pile body truly; (3) the not versatility of ancillary equipment mainly is reflected in the measure portion of the degree of depth, and the stake machine of a producer just must corresponding single-minded depth measurement device, and the precision of machining is also had relatively high expectations, and is difficult to the precision of a whole set of instrument of assurance.

Summary of the invention

The purpose of this utility model provides many pile crowns of cover cement-soil stirring pile construction quality monitoring, recording instrument, and (1) can monitor the grouting amount of same the different pile crowns on the stake machine simultaneously; (2) can write down the density of actual injection pile body cement paste truly; (3) can utilize software device parameter to be changed, guarantee the certainty of measurement of the general and complete machine of ancillary equipment by the debugging keyboard.

The purpose of this utility model is achieved in that (1) adds a mechanical device on the unit head boom hoist cable of cement mixing method, by mobile the become data signal of photoelectric encoder with unit head (pile crown), the interrupt circuit that utilizes single-chip microcomputer is input to the data signal of the degree of depth in the single-chip microcomputer; (2) at the inlet pipe of each pile crown of stake machine, install a pulsed electromagnetic flowmeter additional, with the pulse signal of reflection slurry amount, be input to the timing/timing circuit of single-chip microcomputer, measure the actual grouting amount of each pile crown; (3) at total Grouting Pipe place of stake machine, install the serosity density measurement sensor additional, be input in the single-chip microcomputer by serial communication circuit; (4) with the keyboard circuit people of single-chip microcomputer for being divided into two parts, a part is contained in the technological parameter of importing piling on the instrument for the user in actual mechanical process, another part picks out with extended interface, insert use by the commissioning staff in debug process, the time of initialization system, the parameter of ancillary equipment, the certainty of measurement parameter of complete machine etc.

Owing to adopt above-mentioned scheme, can measure the actual grouting amount of the different pile crowns on the same stake machine simultaneously, the actual serum density that injects pile body, the driving depth of stake machine, the actual pile situation that reflects each strictly according to the facts, also give security simultaneously, solve the versatility of peripheral components for the measurement of equipment.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 4 is user's keyboard and the commissioning staff's keyboard circuit among embodiment of the utility model.

The specific embodiment

Please join Fig. 1, the signal that the electromagnetic flowmeter in a plurality of pile crowns records carries out data through counting timing circuit CPU to be handled.Depth survey simultaneously is by the form of mechanical switching device with photoelectric coding, imports data into cpu data by interrupt interface and handles.Same another density measure is to import cpu data by the sensor amount of recording number into through serial interface circuit to handle, and the display screen that connects with CPU is provided with the simulation light beam and shows actual piling situation, and its running parameter is shown in display screen.This instrument is provided with construction parameter setting and ancillary equipment parameter modification device simultaneously, is linked with printer and acoustic-optic alarm with CPU.

Fig. 2 is the circuit diagram that fathoms and gather with the slurry amount.At first the signal that displacement transducer is recorded provides the stack of rising, dropping signal to deliver to single-chip microcomputer 80C52 by U9A interrupt signal is provided.Provide the direction distinguishing signal that rises and descend to the P3 of 80C52 mouth with U10A, U10B.The traffic pulse that is recorded by sensor in

slurry pipe

1 and 2 is sent into the timing interface of 80C52, and the pulse signal that 3,4, the 5 flow conversion that record of slurry pipe get is sent into the 80C52 processing via U11 (8253 can compile Timer).

Shown in Figure 3 is the pulse signal that density sensor records to be sent in the 80C52 by the serial communication mode by U23 (MAX489) handle.

In Fig. 4, button SW1～SW16 offers the user, and button SW17～SW32 provides to the commissioning staff and uses, and inner function is set by the monitoring software of system.
