Description

Technical Field

[0001] The present 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 in which a static pile driver's driving mechanism uses the driver's own weight and a counterweight on the driver frame to drive precast piles into the soil. During static pile driving, construction data must be recorded and organized into forms such as construction records and hidden inspection forms. Currently, these forms are compiled manually, which is labor-intensive and prone to 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. Through the collaborative control algorithm of multiple groups of sensors, the construction data of the static pressure pile machine is collected and uploaded in a fully automatic manner. The intelligent algorithm sets comprehensive filtering conditions for each pile driving process, eliminating the interference of non-pile driving manual operations on the system judgment. The fully automatic and non-contact collection avoids the influence of human intervention on the collected data, ensures the authenticity and reliability of the collected data, and saves labor costs.

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

[0005] A pile driving depth acquisition module includes a positioning base station and an antenna. The positioning base station is set at a fixed position of the static pile driver. The antenna is set on the pile clamp of the static pile driver. The antenna can move downward with the pile clamp to perform pile driving operations. The antenna is used to collect relative position distance data between the antenna and the base station. The relative position data represents the depth of a single pile driving operation.

[0006] A pile length acquisition module includes a first pile-pressing inductive sensor and a second pile-pressing inductive sensor. The first pile-pressing inductive sensor and the second pile-pressing inductive sensor are respectively installed at the highest and lowest points of the static pile driver, and are used to detect the position status of the precast piles. When the first pile-pressing inductive sensor detects the precast pile and the second pile-pressing inductive sensor cannot detect the precast pile, a new pile-pressing status signal can be generated. When the first pile-pressing sensor cannot detect the precast pile and the second pile-pressing inductive sensor detects the precast pile, a single-section precast pile is about to be completely pressed in status signal can be generated.

[0007] A pile foundation verticality acquisition module is provided on the pile clamp for collecting data on the verticality of the precast piles;

[0008] A pile driving force acquisition module, which is used to acquire the pressing force of the static pile driver;

[0009] A data acquisition module is connected to the pile driving depth acquisition module, the pile length acquisition module, the pile foundation verticality acquisition module, and the pile driving force acquisition module, respectively, for analyzing and processing 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 moved by the precast pile between the new pile pressing state and the single section precast pile being fully 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 upright 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 both 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 from 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, it can block the laser radiation 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 no-pile state signal.

[0017] Furthermore, the pile foundation verticality acquisition module is an inclination sensor, which is installed on the pile clamp plane and 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 pile clamp plane based on the inclination of the pile clamp plane.

[0018] Furthermore, the pile driving force acquisition module 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 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 and then obtains the total pile driving force.

[0019] In order to achieve the above-mentioned object, the present invention provides a method for collecting information of an automatic system for collecting information of static pressure pile construction, which is used for any of the above items, and the method comprises:

[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 driver has started to drive the pile. At this time, the position of the positioning base station is recorded and the pile point positioning coordinates are collected. At the same time, the pile foundation verticality acquisition module starts to collect 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 pressure 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-present signal; the pile force acquisition module generates a pressure value, the data acquisition module determines that the second pile section is in the pile-pressing process, and the first and second pile sections are connected by welding. 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 and the current sensor does not detect welding current, the data acquisition module determines that it is a pile driver. At this time, the penetration depth and pile top elevation of the entire pile are calculated. The penetration depth of the entire pile is calculated by superimposing the relative position distance data between the mobile antenna and the positioning base station. The pile top elevation is calculated by subtracting the ground elevation of the pile point from the penetration depth of the entire pile.

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

[0025] The automatic collection system and method for static pile construction information provided by the present invention adopt a fully automatic method to collect and upload static pile driver construction data through a collaborative control algorithm of multiple sets of sensors. The intelligent algorithm sets comprehensive filtering conditions for each pile driving process, eliminating the interference of non-pile driving human operations on system judgment. The fully automatic and non-contact collection avoids the influence of human intervention on the collected data, ensures the authenticity and reliability of the collected data, and saves labor costs.

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

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

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

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

[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 and lowest points of the static pile driver 10 and are used to detect the position status 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 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 provided 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 moved by the precast pile 30 between the new pile pressing state signal and the single-section precast pile almost 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 down 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 up, the corresponding single displacement will be subtracted. Therefore, the total pile pressing depth is the vector sum of the pile clamp displacements. 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 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. The through-beam photoelectric sensors include a transmitting end 211 and a receiving end 212. The transmitting end 211 and the receiving end 212 of the first pile-pressing inductive sensor 210 are preferably fixed above the upright 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 sensing sensor 220 are preferably respectively disposed on both 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 from 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 beam can be blocked so that the receiving end 212 cannot receive any 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 beam 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] Furthermore, 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 being pressed in. In addition, the total displacement of the pile 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 prefabricated pile.

[0051] The total displacement of the pile 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 inclination of the plane of the pile clamp 20;

[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 and then obtains the total pile driving force.

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

[0057] Based on the automatic collection system for static pile construction information constructed by the above scheme, this scheme also provides a collection method. 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 has started pile driving. 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 collect 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 generates a pressure value, the data acquisition module determines that the first section of the pile is in the downward pressure process, and records the relative position distance data between the mobile antenna 120 and the positioning base station 110 to collect the pile driving depth;

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

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