Embodiment Construction
[0022] Such as figure 1 As shown, it is a schematic flow chart showing the construction method of the isolation pile for the deformation control of the shield tunnel passing through the building at a short distance provided by the present invention. The isolation pile construction method for the deformation control of the shield tunnel passing through the building at a short distance is used for shield construction When passing through in a short distance, the settlement is controlled to protect historical buildings. The implementation steps of the isolation pile construction method of the shield tunnel passing through the deformation control of the building in a short distance include: pouring a reinforced concrete force transmission platform, continuing the steps of sinking piles to form holes, and Install reinforcement cages and pour concrete, and perform auxiliary grouting measures.
[0023] In the step of pouring the reinforced concrete force transmission platform, accord...

The invention relates to a method for constructing an isolation pile, in particular to a method for constructing an isolation pile applied for a to go through a shield tunnel for deformation control of historic structures, buildings and structures at short distance; the method is characterized by employing an extension-type pile sinking and pore-forming steps, an outer sleeve and a spiral drill pipe arranged in the outer sleeve are sunk respectively by clockwise and counterclockwise drilling method through a full circle swinging jacketing machine; the middle and outer sleeve rotate counterclockwise, the spiral drill pipe rotates clockwise to take earth out of the outer sleeve and serves as a protective wall for the outer sleeve and assists in double size inter-pile slip casting of cement paste and water glass, thus effectively controlling subsidence caused in the process of constructing the isolation pile and controlling ground subsidence caused when a shield passes through the historic structures and ensuring structure safety of the historic structures.
Description
technical field [0001] The invention relates to a construction method of an isolation pile, in particular to an isolation pile construction method for controlling the settlement of a building when the shield tunnel passes through the building at a short distance. Background technique [0002] Due to the complexity of shield tunneling construction technology, the surface settlement of the soil layer above the shield cannot be completely eliminated at present. Especially for historical buildings with high historical value, weak foundation and extremely fragile structure near the shield tunnel construction site, the settlement effect caused by shield tunnel construction will deeply damage the structure of historical ancient buildings. Advanced airtight shield technology still cannot completely eliminate surface subsidence. [0003] At present, most of the simple construction and low cost mixing isolation piles and ordinary cast-in-situ piles are used to block the disturbance o...
