Problems solved by technology

[0002] The cement-soil mixing pile is a method for reinforcing the low foundation of saturated soft clay. It uses cement as the curing agent, and through a special mixing machine, the soft soil and the curing agent are forced to mix deep in the foundation. A series of physical and chemical reactions produced between them make the soft soil harden into a high-quality foundation with integrity, water stability and certain strength. The existing cement mixing pile construction method has long construction period, high cost and scientific construction method. Low

Embodiment

[0033] Example: such as figure 1 Shown, the invention provides a kind of cement mixing pile construction method, comprises the steps:

[0034] 1. A cement mixing pile construction method, comprising the steps:

[0035] 1. Measurement and setting out

[0036] Carry out measurement and setting out according to the design drawings and review, after confirming that there is no error, do a good job of recording and corresponding ground marking protection work, the positioning deviation of the pile position shall not exceed 50mm, measure the ground elevation, and determine the pile bottom elevation;

[0037] 2. Mechanical alignment

[0038] Move the deep layer mixer to the designated pile position and align it. The centering error is not greater than 50mm. After the stirring shaft reaches the design depth, then lift the deep layer mixer while stirring, and the verticality deviation is not greater than 1.5%L;

[0039] pre-stirring sinking

[0040] After the cooling water circulat...

Abstract

The invention discloses a construction method using a cement mixing pile. The construction method comprises the following steps of surveying and setting out, mechanical in-place centralizing, pre-stirring sinking, cement paste preparation, guniting, stirring, lifting, repeated stirring, machine tool cleaning and pipeline movement. Construction is performed by adopting the construction method of the cement mixing pile, a piling machine is high in working stability, the cement mixing pile mixes soft soil and cement paste at the deep part of a foundation through a deep-layer stirring machine, sothat soft soil is hardened and the strength of the foundation is improved. The method is suitable for soft soil treatment, a treatment effect is remarkable, the treated soft soil can be very quickly used, the construction cost can be reduced and a foundation treatment construction period is shortened on the premise that the construction quality is ensured in constructional engineering construction, heavy foundation pit excavation or foundation soil change and filling is not easily performed due to consideration of short construction period and cost, and the construction method using the cementmixing pile is more economic and scientific.

Description

technical field [0001] The invention relates to the technical field of foundation construction, in particular to a cement mixing pile construction method. Background technique [0002] The cement-soil mixing pile is a method for reinforcing the low foundation of saturated soft clay. It uses cement as the curing agent, and through a special mixing machine, the soft soil and the curing agent are forced to mix deep in the foundation. A series of physical and chemical reactions produced between them make the soft soil harden into a high-quality foundation with integrity, water stability and certain strength. The existing cement mixing pile construction method has long construction period, high cost and scientific construction method. Low. Contents of the invention [0003] The invention provides a cement mixing pile construction method, which can effectively solve the above-mentioned problems in the background technology. [0004] In order to achieve the above object, the pr...
