Problems solved by technology

From the perspective of quality control, this link has two limitations: (1) it belongs to post-event inspection, and it is impossible to find problems in the construction process in time; (2) it belongs to sample sampling inspection, and the frequency of sampling inspection is low, so it cannot be comprehensively evaluated

Embodiment 1

[0056] Example 1: Combining Figure 1-Figure 5 , the present invention is further described:

[0057] figure 1 It is the detailed implementation process of the monitoring method. The first is to collect on-site data, and then use the monitoring instrument to generate monitoring results, and then carry out construction quality assessment. The construction quality evaluation is mainly through the comprehensive evaluation of three indicators, which are pile length, strength and uniformity indicators.

[0058] figure 2 In order to monitor the connection mode of the equipment, the drill pipe 2 is provided with a stirring head 3, the bottom of the drill pipe 2 is provided with a depth sensor 4, and the top is provided with an inclination sensor 1 and a density sensor 5, and the inclination sensor 1, the density sensor 5 and the depth sensor 4 The deep mixing pile monitor 7 is respectively connected, the inclination sensor 1 can record the pile body inclination and the number o...

Abstract

The invention discloses a mixing pile quality evaluation method based on a construction remote monitoring system. The evaluation method mainly comprises the following steps: acquiring field data; determining evaluation indexes of cement mixing pile construction monitoring; analyzing change of evaluation indexes and standard penetration; establishing an empirical relationship between the evaluationindex and the standard penetration strike number; determining a strength scoring method, a uniformity scoring method and a pile length scoring method of the cement mixing pile; and determining the comprehensive scoring method of the cement mixing pile. Compared with a traditional cement mixing pile body quality detection method, the method has the advantages that problems can be found in time inthe construction process, and rapid evaluation of the construction quality of each pile can be achieved through a remote monitoring system.

Description

technical field [0001] The invention belongs to the field of quality monitoring of cement-soil mixing piles, and in particular relates to a method for evaluating the quality of mixing piles based on a construction remote monitoring system. Background technique [0002] Cement-soil mixing pile is one of the most commonly used foundation treatment methods in soft soil areas. It can effectively improve foundation bearing capacity, reduce post-construction settlement and improve slope stability. However, since most of the construction procedures of cement mixing piles are carried out underground, the control of their construction quality has been difficult to solve well. Common quality problems of cement mixing piles include short piles, too little cement, and uneven pile strength. At present, the most important part of construction quality assurance of cement mixing piles is construction quality inspection: static load test, core pulling for unconfined compressive strength, f...
