Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

It should be noted that all actions of acquiring signals, information or data in the present application are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

The application provides a construction early warning method for a cast-in-situ bored pile, which is shown in a flow chart of the construction early warning method for the cast-in-situ bored pile shown in the attached drawing 1; the method may comprise the steps of:

in the step S102, in the process of manufacturing the reinforcement cage, key parameters of the reinforcement cage are obtained, and early warning is carried out according to the key parameters of the reinforcement cage.

In this embodiment, the key parameters of the reinforcement cage may be the main reinforcement spacing, the stirrup spacing, the cage diameter, the cage length, and the cage top elevation.

And determining the difference value between the construction value and the design standard value of the key parameter of the reinforcement cage, and if the difference value reaches a preset reinforcement cage difference value early warning threshold value, alarming by adopting an alarming device, wherein the alarming information can be sent out, and can be voice or displayed on a display screen of the electronic equipment for characters.

The key parameter early warning threshold value of the reinforcement cage can be flexibly set, and can be set to be 80% or 90% of the difference threshold value of the key parameters of the reinforcement cage specified by the specification.

For example, the difference threshold value specified by the specification of the length of the reinforcement cage is 100 mm, the early warning threshold value of the length parameter can be set to 80 mm, and if the deviation of the actual length is equal to or greater than 80 mm, an alarm can be given.

After obtaining the key parameters of the reinforcement cage, the user can input the key parameters into the electronic equipment, and the electronic equipment can be movable electronic equipment. The electronic equipment is provided with a display screen which can display characters, and a sound production device which can give an alarm by voice. And after alarming, reminding a user of timely adjusting the reinforcement cage.

And step S104, after the reinforcement cage is manufactured, early warning is carried out according to drilling parameters of a single drill hole in the drilling construction process.

In this embodiment, in the drilling process, drilling parameters can be obtained, and if the deviation value of the drilling parameters reaches the early warning difference threshold value, an alarm can be given to the user, and the drilling machine can be stopped in time. Wherein, the drilling parameters can be the coordinates of the pile, the diameter of the hole, the verticality of the hole, the depth of the hole and the thickness of the sediment.

The drilling early warning difference threshold value can be flexibly set and can be set to be 80% or 90% of the difference threshold value specified by the specification.

The electronic equipment can be arranged in a cab of the drilling machine, the noise is high on the construction site, and if the electronic equipment is arranged in the cab, the electronic equipment gives an alarm voice, can remind a drilling driver in time and plays a role in giving an alarm in time. For example, if the depth of the borehole exceeds a predetermined depth value, the warning device may issue a voice prompt alerting the driver to stop digging the hole.

In step S106, after the drilling construction is finished, in the process of pouring concrete, pouring parameters are obtained, and early warning is carried out according to the pouring parameters.

In the present embodiment, the concrete pouring parameters include: slump, test piece strength, filling coefficient and filling time.

Taking slump as an example, in a construction site, a concrete sample is obtained, a measured value of the slump of the concrete is obtained and then input into the electronic equipment, and the electronic equipment compares the measured value with a preset theoretical design value of the slump. If the difference value between the slump and the theoretical design value is larger than a preset difference value early warning threshold value, the slump is unqualified, alarm information is sent out in time to give an alarm so as to remind field personnel, and the mix proportion of the concrete needs to be adjusted so as to meet the slump requirement.

The concrete pouring parameter difference early warning threshold value can be flexibly set. For example, the concrete pouring parameter difference early warning threshold may be set to 80% or 90% of the difference threshold of the concrete pouring parameter specified by the standard specification.

The difference threshold of the key parameters can be determined according to T _ CECS 592-2019-cast-in-situ bored pile construction technical standard.

The method of the invention respectively carries out parameter measurement and early warning work in the three aspects of manufacturing of the reinforcement cage, drilling construction and pouring construction, can obviously provide the engineering quality of the whole drilling and pouring construction, and is beneficial to avoiding the situations of engineering accidents, rework and the like caused by the failure of key parameters.

The quality of the engineering site is improved.

In order to realize more refined quality evaluation work, in one implementation mode, after the reinforcement cage is manufactured, a reinforcement cage quality score is generated according to the reinforcement cage key parameters.

In this embodiment, if the difference value of the key parameters of the steel reinforcement cage is less than or equal to the difference threshold value, quantitative scoring may be performed, and if the difference value is greater than the difference threshold value, the score is zero. For the condition that the difference value of the key parameters of the reinforcement cage is smaller than or equal to the difference value threshold value specified by the specification, the deduction value can be set to be positively correlated with the deviation value.

For example, a predetermined score may be set for each key, see table 1:

main rib spacing	25 minutes
		Space between stirrups	25 minutes
Cage diameter	25 minutes
		Cage length	25 minutes

TABLE 1

For example, if the difference between the measured cage length and the design value is greater than the error threshold specified by the specification, 25 points are completely deducted. If the difference of the cage length is within the error threshold value range specified by the specification, the deducted fraction is determined according to the proportion relation of the actual difference and the difference threshold value. The subtracted fraction = the actual deviation/difference threshold x the predetermined fraction for this parameter. For example, the specification for the length of the reinforcement cage specifies a difference threshold of 100 mm, while if the actual deviation is 10 mm, the score subtracted is 2.5 points, and the parameter score is 22.5 points. For another example, if the actual deviation is 20 mm, the score of the subtraction is 5 points, and the parameter score is 20 points.

In some embodiments, the parameter of the reinforcement cage further comprises a cage top elevation in order to control whether the lowering of the reinforcement cage is qualified. The elevation of the top of the cage is the depth of the steel reinforcement cage after the steel reinforcement cage is completely transferred. If the difference value between the construction value and the design value of the cage top elevation is larger than a preset early warning difference value threshold value, alarm information can be sent out in time. And if the difference value of the cage top elevation is within the error threshold value range specified by the specification, determining the deducted fraction according to the proportional relation between the actual difference value and the difference threshold value. Illustratively, the top elevation of the cage alone may be set to a predetermined score, for example, 40 points, and if the actual difference is greater than the difference threshold specified by the specification, the difference is rejected and 40 points are deducted. If the actual difference is less than the difference threshold specified by the specification, the installation ratio determines the score to be deducted, and thus the score is determined.

In some embodiments, after the single borehole is completed, a borehole quality score is generated from the drilling parameters of the single borehole.

Wherein, above-mentioned drilling parameter includes: pile position coordinates, drilling depth, perpendicularity, drilling diameter and sediment thickness.

Wherein the perpendicularity is determined according to the offset distance and the hole depth of the hole.

See table 2 for drilling parameter ratings.

Pile position coordinate	20 minutes
		Depth of drilled hole	20 minutes
Verticality of a plane	20 minutes
		Diameter of drilled hole	20 minutes
Thickness of sediment	20 minutes

TABLE 2

If the difference in the drilling parameters is within the difference threshold specified by the specifications, the subtracted score is determined as a function of the ratio of the actual difference to the difference threshold. The subtracted fraction = the actual bias/difference threshold gamma the predetermined fraction for the parameter. For example, the specification for hole depth specifies a difference threshold of 300 mm, while if the actual deviation is 30 mm, the number of subtracted points is 2, and the parameter is 18. As another example, if the actual deviation is 60 mm, the score of the subtraction is 4 points and the parameter score is 16 points. If the difference in the drilling parameters is above the difference threshold range specified by the specifications, the subtracted score is determined in proportion to the actual difference and the difference threshold. For example, if the actual deviation is 310 mm, 20 points are deducted, and the score is 0.

After determining the score for each borehole, the score for the entire borehole project may be determined from the score for each borehole.

For example, see table 3:

first bore hole	80 minutes
		Second bore hole	90 minutes
Third bore hole	70 minutes
		Fourth bore hole	60 minutes
Fifth bore hole	50 minutes

TABLE 3

The average scores of the five drill holes can be determined, and the quality performance of the engineering team in the drilling construction can be represented by the average scores.

and controlling an alarm device to send out second alarm information in response to the fact that the difference value between the construction value and the design value of the drilling parameter is equal to or larger than a preset early warning difference value threshold value.

The drilling early warning difference threshold value can be flexibly set and can be set to be 80% of the difference threshold value specified by the specification. For example, the specification of the hole depth specifies that the difference threshold is 300 mm, and if the actual deviation is 241 mm, a second alarm message is sent.

And after the pouring is finished, determining a pouring construction quality score according to the pouring parameters.

In this example, see table 4 for illustration:

slump constant	25 minutes
		Strength of test piece	25 minutes
Filling coefficient	25 minutes
		Time of perfusion	25 minutes

TABLE 4

And if the difference value of the pouring parameters is within the range of the difference value threshold value specified by the specification, determining the deducted fraction according to the proportional relation between the actual difference value and the difference value threshold value. The subtracted fraction = the actual deviation/difference threshold gamma is a predetermined fraction of the parameter. For example, the value specified by the specification of the filling coefficient is 1, and is greater than or equal to 1, and the full score can be obtained. The warning value may be set to 0.8. If less than 0.8, alarm, if less than 0.8, deduct all scores, 0. If between 0.8 and 1, a deduction score value may be determined. The subtracted fractional value = (1-coefficient) predetermined fractional value. For example, if the coefficient is 0.9, the fractional value of the subtraction is 2.5 points.

In this embodiment, the quality score of the steel reinforcement cage, the quality score of the drilled hole and the quality score of the pouring construction may be summed to obtain the quality score of the whole drilling pouring construction. The construction team can be independently checked by independently applying the steel reinforcement cage quality score, the drilling quality score and the pouring construction quality score.

The method is beneficial to performance assessment of construction units by scoring, improves the accuracy of engineering quality assessment, can be used for independently assessing different construction tasks and assessing the total engineering. The construction quality of a construction unit is improved.

In an embodiment, in step S102, before the construction, the early warning is performed according to the key parameter of the steel reinforcement cage, and the method may further include the following steps:

obtaining a design value and a construction value of key parameters of the reinforcement cage; determining a construction error value of the key parameter according to the design value and the construction value of the key parameter; determining the quality score of the reinforcement cage according to the construction error value; and if the construction error value is greater than a preset early warning error threshold value, first warning information is sent out.

The key parameter early warning error threshold of the reinforcement cage can be flexibly set and can be set to be 80% of the difference threshold of the key parameters of the reinforcement cage specified by the specification. For example, the difference threshold value specified by the specification of the length of the reinforcement cage is 100 mm, the early warning threshold value of the length parameter can be set to 80 mm, and if the deviation of the actual length is equal to or greater than 80 mm, an alarm can be given to send out first alarm information.

According to the content regulation of T _ CECS 592-2019-cast-in-situ bored pile construction technical standard, the error threshold of the main rib spacing is 10 mm, the error threshold of the length is 100 mm, the error threshold of the stirrup spacing is 20 mm, and the error threshold of the diameter is 10 mm.

In one embodiment, in the process of pouring concrete, obtaining pouring parameters, generating a pouring construction quality score according to the pouring parameters, and performing early warning, the method may further include the following steps:

The concrete pouring parameter difference early warning threshold value can be flexibly set. For example, the concrete pouring parameter difference early warning threshold may be set to 80% of the difference threshold of the concrete pouring parameter specified by the standard specification.

In this embodiment, with reference to table 4, if the error value of the perfusion time is greater than the predetermined early warning error threshold, a third warning message is sent out, and a score is generated.

To avoid the occurrence of overfill, in one embodiment, the pouring parameter is a pouring time;

determining the design value of the perfusion time may further comprise the steps of:

and acquiring the designed top surface elevation of the single pile.

And determining the theoretical poured concrete amount according to the designed top surface elevation, the diameter of the drilled hole and the filling coefficient.

Specifically, the top elevation is the height of the drilling cylinder according to the above design. The area of the cross section of the bore hole is determined from the diameter of the bore hole as described above. The volume of the cylindrical body of the borehole can be determined from the area of the cross-section and the elevation of the designed top surface as described above. The product of the volume of the cylinder of the borehole and the filling coefficient obtains the theoretical amount of poured concrete.

And determining the design value of the pouring time according to the pouring amount of the tank truck in unit time and the theoretical poured concrete amount.

Illustratively, the actual perfusion time is 10 minutes and 30 seconds, the theoretical design value is 10 minutes, and the difference is 30 seconds. The difference threshold is 1 minute. In this case, pass. If the actual pouring time is 12 minutes, the difference value is 2 minutes and is greater than the difference value threshold value by 1 minute, the method is unqualified and gives an alarm in time, so that the risks of huge economic loss, rework and dismantling caused by continuous pouring after the target elevation is reached are avoided.
