Embodiment

[0110] The Jinpu Interchange, the ninth bid of the Chaoshan Ring Expressway, is located in the soft ground such as paddy fields and fish ponds. The original design treatment schemes include bagged sand wells, plain concrete piles, and prestressed pipe piles. According to the on-site investigation data such as on-site excavation, the soft foundation in the Jinpu Interchange is a shallow soft foundation. According to the Minutes of the Provincial Transportation Group Work Conference [2017] (159), the meeting agreed to cancel all deep soft foundation treatment plans within the scope of the interchange. , according to the results of drilling and static penetration testing, the replacement and filling treatment plan is adopted. Since Jinpu Interchange is located in Chaoyang City, Shantou City, there is no spoil site nearby, and soft soil transportation will cause serious pollution to the city. The in-situ solidification technology is used to avoid the transportation of waste soft s...

Abstract

The invention discloses a shallow soft foundation strong on-site solidification treatment construction method. The shallow soft foundation strong on-site solidification treatment construction method comprises the following specific steps of 1, surface cleaning; 2, dividing blocks; 3, blending a curing agent; 4, stirring in situ by strong stirring equipment; 5, conducting in-situ curing treatment; 6, conducting prepressing and maintaining; and 7, leveling the field. The method has the effects that the thickness, uniformity, strength, foundation bearing capacity and the like all meet the construction quality requirements, and construction is safe.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a construction method for strong in-situ solidification of shallow soft foundations. Background technique [0002] The strong in-situ solidification treatment is proposed on the basis of borrowing foreign technology under the background of increasing shortage of high-quality sand and gravel fillers and increasing cost. This treatment technology is an in-situ soil reinforcement technology that uses a curing agent to solidify soil such as soft soil in situ to make the soil reach a certain strength or other requirements for use. The strong in-situ solidification construction method is to use the strong mixing head of the in-situ solidification system, the excavator, the curing agent automatic feeding system and other curing materials and equipment to realize the uniform mixing of the curing agent and the soil to make the soil reach a certain strength. . Strong in-situ curing constructi...
