Static Pressure Caisson Machine

Short Description:

The static pressure caisson machine has high construction accuracy and verticality control capabilities. It can complete the intrusion, excavation and underwater bottom sealing of a 9-meter-deep well within 12 hours. At the same time, it controls the ground settlement within 3 centimeters by maintaining the stability of the bearing layer. The equipment can also reuse steel casings to reduce material costs. It is also suitable for geological conditions such as soft soil and silty soil, reducing vibration and soil squeezing effects, and has less impact on the surrounding environment.

General Description

Performance Characteristics

Compared with the traditional caisson method, it does not require temporary support measures such as high-pressure jet grouting piles, reducing construction facility costs and ground disturbance.‌

Applications

The static pressure caisson machine is a kind of special construction equipment. It is mainly used for the construction of working wells or caissons in underground projects. It presses the steel casing into the soil layer through static pressure, and at the same time cooperates with internal excavation to achieve sinking.

Its core uses include: ‌During caisson construction, the static pressure caisson machine tightens the steel casing through a hoop device and applies vertical pressure, gradually embedding it into the soil layer. It is suitable for municipal engineering, bridge foundations, sewage treatment plants, underground passages
