Abstract

The invention discloses an automatic recording instrument for static pressure pile construction and a static pressure pile construction device. The automatic recording instrument comprises a measuring unit and a data acquisition processing unit, wherein the measuring unit comprises a pile pressing force sensor and a pile pressing depth sensor; the data acquisition processing unit is provided witha main control module and a data acquisition module and an input and output module that are respectively connected into the main control module; the pile pressing force sensor and the pile pressing depth sensor are both connected into the data acquisition module; the pile pressing force sensor is installed in a hydraulic oil circuit of a hydraulic cylinder of a static pile pressing machine; the pile pressing depth sensor is installed on a support of the static pile pressing machine; and the outer periphery of a friction wheel is in contact and fit with a pile pressing platform. The automatic recording instrument for static pressure pile construction is convenient to install and suitable for working environments of high on-site dust concentration, oil pollution and the like. The measuring way that a roller rotates and moves is adopted, the structure is sturdy and durable and suitable for continuous operation, and the proper signal pulse width ensures sufficient pulse interval and anti-interference property.

Description

technical field [0001] The invention relates to a static pressure pile construction device and a recording instrument. The recording instrument is used for displaying and recording pile pressure data during the static pressure pile construction process. technical background [0002] During the construction of static pressure piles, static pressure pile machines are generally used to carry out hydraulic pile sinking operations on static pressure prefabricated piles. Static pressure pile machines generally include brackets and pile pressing platforms. Pile, the pile pressing platform is driven by a hydraulic cylinder installed on the bracket, which can press the static pressure prefabricated pile into the ground. [0003] In today's "building crooked", "building cracked", "building collapsed" and other building foundation pile foundation (underground concealed engineering) safety issues have become the focus of general attention from all walks of life. According to market surv...
