Embodiment Construction

[0011] The vacuum preloaded mud closed wall shall be constructed according to the following construction methods and steps.

[0012] ①. Pile driver in place: The surveyor releases the pile position, the deviation is not greater than 5cm, and uses a thin bamboo skewer (the bamboo tip is painted with red paint) as the pile position mark. Pay special attention to the pile position marks when the pile driver is shifted to prevent the thin bamboo skewers from breaking or shifting. Under the command of a special person, use the walking device at the bottom of the pile driver to move the pile driver, and use a level ruler and a positioning hammer to calibrate accurately. The pile driver must be kept horizontal so that the mixing pile driver is vertical, and the verticality deviation is not more than 1%. In order to ensure the accuracy of the pile position, positioning cards must be used, and the centering error of the pile position is not greater than 5m. The support of the pile dr...

Abstract

The invention discloses a construction method of a vacuum pre-pressed mortar closed wall, wherein a double-row cement and clay mixer is adopted for vertical mixing according to the pre-designed pile position, cement mortar of corresponding required amount is injected synchronously, the mixer is lifted up at the uniform speed of 0.3 to 0.5m / min, the mixer is mutually lap-jointed for 200mm, and repeated mixing, repeated lowering and lifting mixing operations are re-performed after accomplishing the first lifting and mixing procedure until the pile is formed, namely, the cement mortar enclosing wall with rather strong sealing performance is formed.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method of a vacuum preloaded mud closed wall. Background technique [0002] The vacuum preloading method was first proposed by Professor W.Kjellman of the Royal Swedish Geological Institute in 1952. It belongs to a static drainage consolidation method, which is to lay a sealing film on the surface of the foundation, and vacuumize through the corresponding equipment to make the sand cushion (about 40-50cm thick) and the vertical drainage channel in the soil under the sealing film It is a soft soil foundation reinforcement method that forms negative pressure and accelerates the discharge of pore water, thereby consolidating the soil and increasing its strength. It is mainly applicable to silt, muddy soil and other soft clays that can be drained and consolidated and can form negative excess hydrostatic pressure boundary conditions. [0003] When the ...
