Embodiment Construction

[0028] A recording method for the construction of compacted graded gravel piles, comprising the steps of:

[0029] Step 1: Install the recorder

[0030] The recorder includes a recorder host, a current sensor, a load cell and a depth sensor;

[0031] The host of the recorder is installed on the pile driver operation platform which is convenient for operators to observe and operate; the current sensor is installed in the electric control cabinet to record the piling current during construction; the load cell is connected in series between the hopper and the wire rope hook, and is transmitted through wireless Bluetooth Record the weight of each feeding; drill a hole on the derrick of the drilling rig, fix the depth sensor on the derrick of the drilling rig with screws, loosen the pinch wheel, put the transmission wire rope between the pinch wheel and the drive wheel or at the chain drive shaft, Adjust the base of the sensor so that the transmission wire rope / chain is in the nor...

Abstract

The invention relates to a recording method for the construction of compacted and graded gravel piles. The recorder comprises a recorder host, a current sensor, a weighing sensor and a depth sensor; On the platform; the current sensor records the piling current during construction through the installation of the electric control cabinet; the weighing sensor records the weight of each feeding through wireless Bluetooth transmission; the depth sensor records the real-time depth of the pile pipe through the data line; all recorded data Collected by the sensors installed on the pile driver, and finally reflected on the display screen of the recorder host, the construction of the compacted gravel pile is controlled by controlling the feeding amount, the pile length and the current; the recorded data of the present invention is true and accurate, and the construction management cost is saved , improve management efficiency and ensure construction quality.

Description

technical field [0001] The invention relates to a recording method, in particular to a recording method for construction of compacted and graded crushed stone piles. Background technique [0002] The total length of the OCH Expressway is 9.32 kilometers, and the soft soil foundation is mainly distributed within 2 kilometers of the KER interchange. According to the geological survey, the soft soil of this project is mainly peat soil and silty clay, the thickness is generally 5-8 meters, and the thickness is up to 15 meters. It has high natural water content, large natural void ratio, small natural bulk density, large permeability coefficient and Low sensitivity and so on. For the treatment of soft soil foundation, according to the distribution and thickness of the soft soil foundation in different road sections, the soft foundation treatment is mainly carried out by vibrating compacted gravel piles, and the overload preloading treatment method is adopted to ensure the settle...
