Embodiment Construction

[0020] refer to figure 1 and figure 2 , the foundation pit enclosure structure, including a pre-set drill hole according to the set position, the drill hole is provided with a cement mixing pile 3 for improving the strength of the foundation, and the inner side of the cement mixing pile 3 is close to the cement mixing pile Sectional steel 2 for improving the rigidity of the enclosure structure is arranged in the soil body 1 of 3 and at intervals along the width direction of the cement mixing pile.

[0021] The section steel 2 is H steel.

[0022] A kind of construction method of foundation pit enclosure structure as described above, described construction method comprises the following steps:

[0023] (31) Use the mixing pile machine to complete the drilling, and at the same time, inject the cement slurry strengthening agent into the soil at high pressure from the front end of the drill bit. The cement slurry strengthening agent and the chopped soil are fully and vigorously...

Abstract

The invention discloses a foundation pit support structure and a construction method thereof. The pit support structure comprises a drill hole preset in advance according to the set position; the drill hole is internally provided with a cement mixing pile used for improving the ground strength, and structural steel used for improving the stiffness of the support structure is arranged in a soil body, close to the cement mixing pile, on the inner side of the cement mixing pile and arranged in the width direction of the cement mixing pile at intervals. By means of the foundation pit support structure and the construction method, the structural steel is placed into soil beside the cement mixing pile, so that the support rigidity is improved, the structural steel can be taken out more conveniently and rapidly, repeated utilization is achieved, and the good support effect is achieved.

Description

technical field [0001] The invention relates to a foundation pit enclosure structure and a construction method thereof. Background technique [0002] Publication number is that the Chinese patent of CN102926382A discloses a kind of enclosure method, and it completes drilling, grouting, stirring immediately after lifting profiled steel and it accurately inserts the work in the cement-soil pile by a SMW engineering method pile driver. In the invention, the cement-soil continuous wall and the section steel inserted therein together form a structure with resistance to bending and shearing through the processes of drilling, grouting and mixing in the soil. But it is more difficult to pull out the section steel for recycling. [0003] The traditional SMW construction method is a kind of rigid composite enclosure structure, which cuts the soil in the original formation through a special super-power and super-torque mixing pile drilling rig, and at the same time injects the cement ...
