Problems solved by technology
In actual construction, the traditional pile-in depth is completed by manual measurement, and then recorded and reported to the management unit. This method has the following problems: 1) The measurement of the pile-in depth generally requires special measuring instruments such as total station instruments. The actual measurement process requires the cooperation of multiple people, which increases the labor cost
2) There is a possibility of a large deviation from the actual requirements due to human error and subjective intention
[0003] In addition, during the construction of pipe piles, relying on manual experience to decide whether to pick up piles, send piles or receive hammers is highly subjective and prone to under-driving or over-driving, which affects construction quality and leaves potential safety hazards

Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0031] The hammering auxiliary method in this specific real-time mode is realized by the hammering auxiliary system in this specific embodiment, which can accurately monitor the footage of each hammer and the footage of each array, and provide data-based monitoring for the construction process of pipe piles. Objective guidelines to improve the stability and reliability of construction quality.
[0032] 1) Hammer assist system
[0033] refer to figure 1 As shown, a hammering auxiliary system for pipe pile construction includes a hammering number monitoring system and a pile depth monitoring system;
[0034] The hammering number monitoring system includes a proximity switch 1-3 and a host computer 1-1. The proximity switch 1-3 is installed on the top of the hammer frame of the pile driver and faces the direction of the hammer lever 2...

The invention discloses a hammering assistance method and system for pipe pile construction and a hammering data sharing system. Each hammer in the hammering process is evaluated on the basis of the footage of each hammer, objective basis is provided for corresponding hammering decisions (hammer receiving, pile feeding and pile splicing) in combination with the soil penetration depth of a pile, and blindly depending on subjective experience is avoided. After the footage amount of each hammer is smaller than the threshold value of each hammer, the footage amount of each array is monitored and evaluated, and the hammer receiving judgment accuracy is improved. The hammering data sharing system is established on the basis of the hammering assistance system, and supervision and traceability guarantee is provided for pipe pile construction. Through the hammering data of the construction log, reference is provided for determination of the threshold value of each hammer and the threshold value of each matrix, objective reality is better met, along with accumulation of the hammering data in different geological areas, threshold value parameters can be continuously optimized, and therefore continuous improvement of the construction quality is promoted.
Description
technical field [0001] The invention relates to the technical field of pipe pile construction. Background technique [0002] Prefabricated pipe piles are widely used in foundation treatment projects of construction projects, mainly used to improve the bearing capacity of foundations and foundations. One of the common construction methods is the hammering method, that is, pipe piles are driven into the ground by a pile driver. In actual construction, the traditional pile-in depth is completed by manual measurement, and then recorded and reported to the management unit. This method has the following problems: 1) The measurement of the pile-in depth generally requires special measuring instruments such as total station instruments. The actual measurement process requires the cooperation of multiple people, which increases the labor cost. 2) There may be large deviations from actual requirements due to human error and subjective intention. [0003] In addition, during the cons...
