Problems solved by technology

However, in the construction process using this technology, due to human factors, the quality and progress of the project are difficult to control and difficult to manage. Insufficient depth, uneven or discontinuous amount of powder spraying or grouting, so that the project cannot achieve the purpose of design, which leads to restrictions on its implementation in some areas and affects the popularization and application of this technology
In addition, due to the concealment and uneven distribution of underground engineering, the soil properties of the underground soil layer cannot be discovered in time during the construction process, and the design and construction measures cannot be modified in time, which also affects the popularization and application of this technology

Embodiment Construction

[0014] As shown in Figures 1 and 2, first, the footage sensor 2, the flow sensor 3, the density sensor 4, and the rotation sensor 5 are fixed on the cement-soil mixing pile frame 9. Wherein the footage sensor 2 is arranged on the top of the vibrating head 10 to record the depth of the pile in real time; the flow sensor 3 and the density sensor 4 are arranged in the slurry (powder) pipe 12 to record the amount of slurry and the slurry (powder) in real time density; and the rotation sensor 5 is arranged on the stirring shaft 11 below the vibrating head 10 to record the rotation of the stirring shaft 11 in real time and reflect the characteristics of the underground soil; On the collector 1; the data collector 1 is connected with the antenna 7, and the antenna 7 is best arranged on the top of the frame 9 of the cement-soil mixing pile.

[0015] After starting to implement, under the action of the vibrating head 10, the stirring shaft 11 starts to stir, and the cement slurry or po...

Abstract

The present invention relates to the automatic monitoring method for cement-soil stirring pile construction. The present invention has headway, flow rate, density and rotation sensors the collect signals, transmits the signals via antenna or copies the signals via movable memory to computer, and records and processes the signals and data in the computer with proper software. The present invention is one kind of positive real-time dynamic monitoring method and may be used in continuous monitoring of pile construction and real-time analysis of foundation soil strength and other characteristics to avoid artificial engineering quality problem. The monitoring apparatus has small size, convenient carrying about and simple use.

Description

technical field [0001] The invention relates to an automatic monitoring method for cement-soil mixing pile construction, in particular to a real-time automatic monitoring method. Background technique [0002] Cement-soil mixing piles (including slurry-sprayed piles and powder-sprayed piles) are a pile foundation technology formed by using a special mixing machine to press cement slurry or powder into the soil and stir, and form a series of physical and chemical reactions. Compared with other construction techniques, due to its low cost and convenient construction, it has been applied in foundation reinforcement of highways and industrial and civil construction projects. However, in the construction process using this technology, due to human factors, the quality and progress of the project are difficult to control and difficult to manage. Insufficient depth, uneven or discontinuous spraying of powder or grout, make the project fail to achieve the purpose of design, which le...
