In high-rise buildings, pile foundations are widely applied. The pile foundation is a deep foundation consisting of piles and pile bearing platforms (bearing platforms for short) connected with the pile tops or a single pile foundation connected with the pile foundation through columns, and is called the pile foundation for short. If the pile body is completely buried in the soil and the bottom surface of the bearing platform is contacted with the soil body, the pile body is called a low bearing platform pile foundation; when the upper part of the pile body is exposed out of the ground and the bottom of the pile cap is positioned above the ground, the pile body is called a high pile cap pile foundation. However, the depth of the cast-in-place pile is designed to be higher and lower due to geological reasons, the length of the cast-in-place pile is longer and longer, and meanwhile, the verticality and construction quality of a formed hole are greatly influenced by different geological drill rods or pile heads falling in the construction of the ultra-long cast-in-place pile, so that irreversible economic loss is caused to a construction unit, and the construction period is even directly influenced.
At present, passive field observation or experience is mostly adopted to judge whether a drilling machine clamps a drill rod or drops a pile head, so that the problems of inaccurate judgment and after-judgment result are easily caused.
Based on this, the present invention provides a solution to the above technical problem based on a positioning system, the details of which will be explained in the following embodiments.
Referring to fig. 1, as shown in the drawings, the present invention provides a positioning system based hole forming control system for a pile pouring machine, including: the method comprises the steps that a bored pile machine hole forming monitoring system 20, a bored pile machine 10, a lower drill rod connector 100 and an elevation positioning sensor 101 are arranged at a port of the lower drill rod connector 100, and elevation data of a drill rod in the drilling process are monitored based on the hole forming monitoring system 20; and a data incremental processing interaction and evaluation system 30.

And S40, comparing the sinking increment data with the frequency increment maximum early warning value or the frequency increment minimum early warning value, and giving out early warning when the sinking increment data is larger than the frequency increment maximum early warning value or smaller than the frequency increment minimum early warning value.

Figure BDA0002574948900000114
The incremental data processing interaction and evaluation processing system sends out early warning in time and informs an operator to give out early warning in time.
In an implementation manner of this embodiment, the geological data of the survey report or the advanced drilling survey report may be used to adjust the incremental data per unit time of hole forming in the corresponding geological type of the cast-in-place pile machine (i.e., update the database platform library per unit time of hole forming), and the updated database platform library per unit time of hole forming is used to perform secondary correction on the data of hole forming in the test pile of the cast-in-place pile machine.
In an implementation manner of this embodiment, a scheme is provided for correcting the deviation of the condition that the frequency increment early warning value is exceeded, for example, in the geology of type (3), when the sinking increment data is greater than the frequency increment maximum early warning value, it indicates that the sinking speed of the drill rod is too fast at this time (the pile head may drop if the sinking speed continues), at this time, the grouting pile machine may be stopped, the power of the grouting pile machine is reduced by 20%, and the lowering angle of the drill rod is readjusted. It is easy to understand that the herein-described method for stopping the pouring pile machine reduces the power of the pouring pile machine by 20%, and adjusting the lowering angle of the drill rod is a deviation-correcting scheme (also referred to as deviation-correcting measure). The concrete deviation rectifying scheme can be formulated according to the actual construction condition.
When the situation that the bored concrete pile machine gives an alarm in a certain geological type is monitored, corresponding deviation rectifying measures can be called through a preset program to deal with the situation, and accidents are prevented. Due to the fact that the regulation and control method of the pore-forming equipment is monitored in real time and put forward in time, pore-forming of pore-forming on different geological layers is guaranteed not to exceed an early warning value in the whole process, and then pore-forming construction efficiency and construction quality are guaranteed.
In this embodiment, the pore-forming unit time increment database platform library may be constructed by using an SQL data module. The data incremental processing interaction and evaluation system can be developed by adopting a PHP language.
In summary, the invention provides a positioning system-based hole forming control method and system for a pouring pile machine. The method comprises the following steps: constructing a database platform library of hole forming unit time increment database of the pouring pile machine in different geological types; obtaining elevation sinking frequency data of a lowering drill rod in a lowering process, and obtaining sinking increment data in a unit frequency difference according to the elevation sinking frequency data; inquiring the database platform base of the increment of the pore-forming unit time according to the geological type of the downward drill rod to obtain frequency increment early warning values corresponding to the downward drill rod, wherein the frequency increment early warning values comprise a frequency increment maximum early warning value and a frequency increment minimum early warning value; and comparing the sinking increment data with the frequency increment maximum early warning value or the frequency increment minimum early warning value, and giving out early warning when the sinking increment data is larger than the frequency increment maximum early warning value or smaller than the frequency increment minimum early warning value. The drilling rod sinking value and the drilling rod hole forming value of the cast-in-place pile are compared with the early warning value, the comparison result is monitored in real time, and the operation of the cast-in-place pile machine is monitored according to the comparison result, so that the risk of construction quality control of clamping the drilling rod or dropping a drill bit when the cast-in-place pile machine forms the holes is realized, and the construction efficiency is improved.
