Embodiment Construction

[0030] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0031] As shown in Figure 1 and Figure 2, the following steps in this embodiment are carried out:

[0032] (1) Clarify the site geological conditions: the uppermost layer (0.0-0.6m) is an unsaturated soil layer formed by weathering; the lower layer (0.6-13.5m) is a clay layer, which is blue-gray; the lower layer is a sand layer , that is, the upper deep layer of clay and the lower part of sandstone. The water content of the soil samples taken is between 90% and 150%, the clay content is 60%, the silt content is 35%, and the sand content is 5%.

[0033] (2) Carry out indoor mix ratio test, and make test pieces by ...

Abstract

A control method of construction quality of deep mixing piles based on energy consumption monitoring belongs to the technical field of constructional engineering and is characterized by obtaining the best construction parameters and implementing mixing at the site through geologic survey of the construction site, an indoor mixing test, an indoor model pile test and an unconfined compression test. Compared with the prior art, the method can be used for controlling the construction quality of the deep mixing piles more reasonably.

Description

technical field [0001] The invention relates to a method in the technical field of construction engineering, in particular to a method for controlling the construction quality of deep mixing piles based on energy consumption monitoring. Background technique [0002] Deep mixing piles have been successfully used for more than 30 years in the reinforcement of soft soil foundations. The construction process is to mix chemical mixtures (cement, lime, etc.) or lime) obtained by chemical reaction with soil. The factors affecting the strength mainly include the characteristics of the curing agent and the soil on site, the degree of uniformity of mixing and the curing conditions, among which the degree of uniformity of mixing is a key factor, and the quality problems in the project are mainly caused by the unevenness of mixing and mixing. . There are generally two ways to improve the mixing uniformity of cement mixed soil in on-site construction: one is to develop various high-eff...
