Description

Technical Field

[0001] The invention relates to the technical field of pile foundation construction, and in particular to an automatic collection system and method for static pressure pile construction information. Background Art

[0002] Static pile driving is a method of pile foundation construction. It is a pile driving process that uses the pile driving mechanism of a static pile driver to provide reaction force with the deadweight of the pile driver and the counterweight on the frame to press the prefabricated piles into the soil. During the static pile driving construction process, it is necessary to record the construction process data and organize it into construction forms such as construction records and hidden acceptance. The current forms are manually organized, which consumes manpower and is prone to recording errors. Summary of the invention

[0003] In view of the above-mentioned technical problems existing in the existing manual recording of the construction process, the purpose of the present invention is to provide an automatic collection system and collection method for static pressure pile construction information, which uses a multi-group sensor collaborative control algorithm to collect and upload static pressure pile machine construction data in a fully automatic manner. The intelligent algorithm sets comprehensive filtering conditions for each pile driving process, eliminates the interference of non-pile driving manual operations on system judgment, and avoids the influence of human intervention on the collected data through fully automatic and non-contact collection, thereby ensuring the authenticity and reliability of the collected data and saving labor costs.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a static pressure pile construction information automatic collection system, comprising:

[0005] A pile driving depth acquisition module, wherein the pile driving depth acquisition module comprises a positioning base station and an antenna, wherein the positioning base station is arranged at a fixed position of the static pile driving machine, and the antenna is arranged on the pile clamp of the static pile driving machine, and the antenna can move downward with the pile clamp to perform pile driving operation, and the antenna is used to collect relative position distance data with the base station, and the relative position data is a single pile driving depth;

[0006] A pile length acquisition module, wherein the pile length acquisition module comprises a first pile pressing induction sensor and a second pile pressing induction sensor, wherein the first pile pressing induction sensor and the second pile pressing induction sensor are respectively installed at the highest point and the lowest point of the static pile driving machine, and are used to detect the position state of the precast piles, and when the first pile pressing induction sensor detects the precast piles and the second pile pressing induction sensor cannot detect the precast piles, a new pile pressing state signal can be generated; when the first pile pressing sensor cannot detect the precast piles and the second pile pressing induction sensor detects the precast piles, a single-section precast pile is about to be completely pressed in state signal can be generated;

[0007] A pile foundation verticality acquisition module, which is arranged on the pile clamp and is used to collect data on the verticality of the precast piles;

[0008] A pile-pressing force collection module, which is used to collect the pressing force of the static pile driver;

[0009] A data acquisition module, wherein the data acquisition module is connected to a pile driving depth acquisition module, a pile length acquisition module, a pile foundation verticality acquisition module, and a pile driving force acquisition module, respectively, and is used to analyze and process the collected data;

[0010] The data acquisition module can calculate the precast pile driving depth based on the sum of several single pile driving depths;

[0011] The data acquisition module can calculate the total length of the single-section precast pile based on the total vertical distance of the precast pile from the new pile pressing state to the single-section precast pile being completely pressed in state plus the vertical fixed height between the first pile pressing sensing sensor and the second pile pressing sensing sensor.

[0012] Furthermore, the positioning base station is a Beidou positioning base station, and the antenna is a Beidou antenna.

[0013] Furthermore, the first pile-pressing inductive sensor and the second pile-pressing inductive sensor have the same structure, and are both through-beam photoelectric sensors, which include a transmitting end and a receiving end. The transmitting end and the receiving end of the first pile-pressing inductive sensor are respectively fixed above the vertical oil cylinders on both sides of the static pile driver.

[0014] The transmitting end and the receiving end of the second pile-pressing induction sensor are respectively arranged on two sides of the bottom of the pile clamp.

[0015] The transmitting end and the receiving end are arranged in parallel, the prefabricated pile moves between the transmitting end and the receiving end, and the laser beam of the transmitting end can pass through the center position of the pile point and reach the receiving end;

[0016] When the prefabricated pile is located between the transmitting end and the receiving end, the laser radiation can be blocked so that the receiving end cannot receive the signal, so that the first pile-pressing sensing sensor and the second pile-pressing sensing sensor generate a pile state signal. When the receiving end receives the laser radiation emitted by the transmitting end, the first pile-pressing sensing sensor and the second pile-pressing sensing sensor generate a pile-free state signal.

[0017] Furthermore, the pile foundation verticality acquisition module is an inclination sensor installed on the pile clamp plane, which can collect the inclination of the pile clamp and send it to the data acquisition module. The data acquisition module calculates the verticality of the precast pile perpendicular to the inclination of the pile clamp plane.

[0018] Furthermore, the pile driving force collection module is a pressure sensor, which is installed on the main oil pipe and branch pipe of the pressure cylinder. The pile driving force collection module collects the working status and pressure values ​​of the main oil cylinder and the auxiliary oil cylinder respectively and sends them to the data collection module. The data collection module accurately calculates the pressure values ​​of the main oil cylinder and the auxiliary oil cylinder to obtain the total pile driving force.

[0020] S1: The data acquisition module starts the system according to the acquisition signal of the pile driving force acquisition module. When the pile driving force is acquired by the pile driving force acquisition module, it proves that the static pile driving machine starts to drive the pile. At this time, the position of the positioning base station is recorded and the pile point positioning coordinates are acquired. At the same time, the pile foundation verticality acquisition module starts to acquire the verticality index of the pile rod during the pile driving process.

[0021] S2: When the first pile-pressing sensing sensor generates a pile signal, the second pile-pressing sensing sensor generates a pile signal, and the pile force acquisition module has a pressure value, the data acquisition module determines that the first section of the pile is in the downward pressing process, and records the relative position distance data between the mobile antenna and the positioning base station, and collects the pile driving depth;

[0022] S3: When the first pile-pressing induction sensor generates a no-pile signal, and the second pile-pressing induction sensor generates a pile signal; the pile force acquisition module has a pressure value, at this time the data acquisition module determines that it is the pile-pressing process of the second pile, the first pile section and the second pile section are connected by welding, and during welding, the current sensor detects the current and records the welding process and the welding time;

[0023] S4: When the last section of the pile enters, the current sensor does not detect the welding current. The data acquisition module determines that it is a pile driver. At this time, the pressing depth of the whole pile and the pile top elevation are calculated. The pressing depth of the whole pile is calculated by the relative position distance data vector superposition between the mobile antenna and the positioning base station. The pile top elevation is the pile point ground elevation minus the pressing depth of the whole pile.

[0024] S5: The data collected by the pile driving depth collection module, pile length collection module, pile foundation verticality collection module, and pile driving force collection module are summarized in the data collection module, uploaded to the Internet platform under the transmission protocol, and then transferred to the business system for analysis and processing, and displayed in the user's business system.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0034] See also Figure 1 , which is a schematic diagram of the structure of the automatic collection system for static pressure pile construction information provided by the present invention.

[0035] According to the diagram, the automatic collection system for static pile construction information provided by the present invention includes five components: a pile depth collection module 100, a pile length collection module, a pile foundation verticality collection module 300, a pile force collection module 400, and a data collection module.

[0036] Furthermore, the pile driving depth acquisition module 100 includes a positioning base station 110 and an antenna 120. The positioning base station 110 is arranged at a fixed position of the static pile driving machine 10, and the antenna 120 is arranged on the pile clamp 20 of the static pile driving machine 10. When performing the pile driving operation, the antenna 120 can move downward with the pile clamp 20. By moving the antenna 120, the relative position distance data between the positioning base station 110 can be collected, and the position distance data is the single pile driving depth.

[0037] The pile length acquisition module includes a first pile-pressing inductive sensor 210 and a second pile-pressing inductive sensor 220. The first pile-pressing inductive sensor 210 and the second pile-pressing inductive sensor 220 are respectively installed at the highest point and the lowest point of the static pile-pressing machine 10, and are used to detect the position state of the precast pile 30. When the first pile-pressing inductive sensor 210 detects the precast pile 30 and the second pile-pressing inductive sensor 220 cannot detect the precast pile 30, a new pile pressing state signal can be generated. When the first pile-pressing inductive sensor 210 cannot detect the precast pile 30 and the second pile-pressing inductive sensor 220 detects the precast pile 30, a single-section precast pile is about to be completely pressed in state signal can be generated.

[0038] The pile foundation verticality acquisition module 300 is arranged on the pile clamp 20 and is used to collect data on the verticality of the precast pile 30;

[0039] The pile driving force collection module 400 is used to collect the pressing force of the static pile driver 10;

[0040] The data acquisition module is connected to the pile driving depth acquisition module 100, the pile length acquisition module, the pile foundation verticality acquisition module 300, and the pile driving force acquisition module 400, respectively, for analyzing and processing the collected data;

[0041] The data acquisition module 100 can calculate the pile driving depth of the precast pile 30 based on the sum of several single pile driving depths;

[0042] The data acquisition module can calculate the total length of the single-section precast pile 30 based on the total vertical distance of the precast pile 30 between the new pile pressing state signal and the single-section precast pile about to be completely pressed state signal plus the vertical fixed height between the first pile pressing sensing sensor 210 and the second pile pressing sensing sensor 220.

[0043] Specifically, the positioning base station 110 in the pile driving depth collection module 100 is preferably a Beidou positioning base station, and the antenna 120 is preferably a Beidou antenna, and the two cooperate to collect the pressing depth of the prefabricated pile 30 .

[0044] In actual application, when the pile clamp 20 and the precast pile 30 are pressed downward together, the relative position difference ΔH can be used to determine the single pile pressing depth; on the contrary, when the pile clamp 20 is pulled upward, the corresponding single displacement will be subtracted. Therefore, the total pile pressing depth is the vector sum of the pile clamp displacement. Figure 2 As shown, the precast pile pressing depth H can be calculated by the formula.

[0045] Where n is the total number of times a single-section pile is pressed.

[0046] Furthermore, the first pile-pressing inductive sensor 210 and the second pile-pressing inductive sensor 220 in the pile length acquisition module have the same structure, and are both through-beam photoelectric sensors, which include a transmitting end 211 and a receiving end 212. The transmitting end 211 and the receiving end 212 in the first pile-pressing inductive sensor 210 are preferably fixed above the vertical oil cylinders on both sides of the static pile driver 10, respectively.

[0047] The transmitting end 211 and the receiving end 212 of the second pile pressing sensor 220 are preferably respectively arranged at two sides of the bottom of the pile clamp 20.

[0048] The transmitting end 211 and the receiving end 212 are arranged in parallel, and the prefabricated pile 30 moves between the transmitting end 211 and the receiving end 212. The laser beam of the transmitting end 211 can pass through the center of the pile point and reach the receiving end 212.

[0049] When the prefabricated pile 30 is located between the transmitting end 211 and the receiving end 212, the laser radiation can be blocked so that the receiving end 212 cannot receive the signal, so that the first pile-pressing sensing sensor 210 and the second pile-pressing sensing sensor 220 generate a pile state signal. When the receiving end 212 receives the laser radiation emitted by the transmitting end 211, the first pile-pressing sensing sensor 210 and the second pile-pressing sensing sensor 220 generate a pile-free state signal.

[0050] Further, when the first pile-driving sensing sensor 210 generates a no-pile state signal and the second pile-driving sensing sensor 220 generates a pile state signal, it is determined as a state signal that a single-section pile is about to be completely pressed in; when the first pile-driving sensing sensor 210 generates a pile state signal and the second pile-driving sensing sensor 220 generates a no-pile state signal, it is determined as a state signal of the new pile pressing process; in addition, the total displacement of the pile driving between the two states, plus the fixed vertical height between the first pile-driving sensing sensor 210 and the second pile-driving sensing sensor 220, is determined as the length of a single section of the precast pile.

[0051] The total displacement of the pile driving is calculated based on the superposition of the total displacement vectors between the positioning base station 110 and the antenna 120 .

[0052] L i =H+p

[0053] In the above formula: Li is the length of the i-th prefabricated pile; p is the fixed height between the first pile-pressing sensing sensor 210 and the second pile-pressing sensing sensor 220 .

[0054] Furthermore, the pile foundation verticality acquisition module 300 is an inclination sensor, which is installed on the plane of the pile clamp 20 and can collect the inclination of the pile clamp 20 and send it to the data acquisition module. The data acquisition module calculates the verticality of the precast pile 30 perpendicular to the plane of the pile clamp 20 from the inclination of the plane.

[0055] The pile driving force acquisition module 400 is a pressure sensor, which is installed on the main oil pipe and branch pipe of the pressure cylinder. The pile driving force acquisition module 400 collects the working status and pressure values ​​of the main oil cylinder and the auxiliary oil cylinder respectively and sends them to the data acquisition module. The data acquisition module accurately calculates the pressure values ​​of the main oil cylinder and the auxiliary oil cylinder to obtain the total pile driving force.

[0056] Furthermore, a current sensor 600 is provided in the electrical box of the static pressure pile driver 10, and the current sensor 600 can monitor the working state of the pile driver;

[0057] Based on the automatic collection system of static pressure pile construction information formed by the above scheme, this scheme also provides a collection method, and the collection steps are as follows:

[0058] S1: The data acquisition module starts the system according to the acquisition signal of the pile driving force acquisition module 400. When the pile driving force is acquired by the pile driving force acquisition module 400, it proves that the static pile driver 10 starts to drive the pile. At this time, the position of the positioning base station 110 is recorded and the pile point positioning coordinates are acquired. At the same time, the pile foundation verticality acquisition module 300 starts to acquire the verticality index of the pile rod during the pile driving process.

[0059] S2: When the first pile-pressing sensing sensor 210 generates a pile signal, the second pile-pressing sensing sensor 220 generates a pile signal, and the pile force acquisition module 400 has a pressure value, the data acquisition module determines that the first section of the pile is in the downward pressing process, and records the relative position distance data between the mobile antenna 120 and the positioning base station 110 to collect the pile-pressing depth;

[0060] S3: When the first pile-pressing sensing sensor 210 generates a no-pile signal, and the second pile-pressing sensing sensor 220 generates a pile signal; the pile force acquisition module 400 has a pressure value, and the data acquisition module determines that it is the pile-pressing process of the second pile, the first pile section and the second pile section are connected by welding, and the current sensor 600 detects the current during welding and records the welding process and the welding time;

[0061] S4: When the last section of the pile enters, the current sensor 600 does not detect the welding current. The data acquisition module determines that it is a pile driver. At this time, the pressing depth of the whole pile and the pile top elevation are calculated. The pressing depth of the whole pile is calculated by superimposing the relative position distance data vector between the mobile antenna 120 and the positioning base station 110. The pile top elevation is calculated by the pile point ground elevation minus the pressing depth of the whole pile.

[0062] S5: The data collected by the pile driving depth acquisition module 100, the pile length acquisition module, the pile foundation verticality acquisition module 300, and the pile driving force acquisition module 400 are summarized in the data acquisition module, uploaded to the interconnection platform (LOT) under the transmission protocol, and then transferred to the business system for analysis and processing, and displayed in the user business system.
