Technical Field
The utility model relates to a cement stirring stake technical field especially relates to a cement stirring stake crowd of interconnect.
Background
At present, cement soil mixing pile is a method for reinforcing saturated soft clay foundation, which uses cement as curing agent, forcibly mixes soft soil and curing agent in the deep part of the foundation by a special mixing machine, and uses a series of physical and chemical reactions generated between the curing agent and the soft soil to make the soft soil hard to form a high-quality foundation with integrity, water stability and certain strength. In the traditional construction process, the cement mixing piles are independent from each other, and no load is transmitted among the cement mixing piles. In some complex geological conditions, the cement mixing piles are respectively settled and deformed under the action of the overburden load, and large settlement difference can be generated among the cement mixing piles. If the settlement difference is too large, the upper filling soil or the structure is inclined, and the subsequent use function is affected. If the connection between each cement stirring stake can be strengthened, realize that certain load can be transmitted between each cement stirring stake, improve the wholeness of cement stirring stake group stake, must reduce the settlement difference in the follow-up use.
SUMMERY OF THE UTILITY MODEL

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-6, a group of interconnected cement mixing piles includes a plurality of cement mixing piles 1 and inclined cement mixing connecting piles 2; slant cement stirring connecting pile 2 set up between 1 upper portions of adjacent cement stirring stake, just slant cement stirring connecting pile 2 inside be provided with reinforcement 3.
Further, the diameter of slant cement stirring connecting pile 2 be less than the diameter of cement stirring pile 1, the diameter of reinforcement is less than the diameter of slant cement stirring connecting pile 2, the reinforcement is located the middle part of slant cement stirring connecting pile 2.
Furthermore, the included angle between the inclined cement stirring connecting pile 2 and the horizontal plane is 30-45 degrees.
Further, the reinforcing member 3 is a steel pipe.
Further, the diameter value of the slant cement mixing connecting pile 2 is smaller than that of the cement mixing pile 1.
Further, the diameter value of the inclined cement stirring connecting pile 2 is less than one half of the diameter value of the cement stirring pile 1.
