Abstract
The utility model discloses a grouting type composite spiral anchor pile foundation, which relates to the technical field of assembly type building equipment and comprises an anchor rod, an anchor disc and a high-pressure grouting pipe, wherein the anchor disc is spirally rotated around the anchor rod and fixedly connected to the side wall of the anchor rod, the high-pressure grouting pipe is arranged in the anchor rod and extends to the outside of the anchor rod, and the tail end of the high-pressure grouting pipe is provided with a high-pressure grouting hole. The utility model enhances the bearing capacity of the screw anchor, reduces the variability of the basic bearing capacity of the screw anchor and reduces the consumption of steel.
Description
Technical Field
The utility model relates to the technical field of assembly type construction equipment, in particular to a grouting type composite spiral anchor pile foundation.
Background
At present, the assembly type building is developed rapidly, and factory prefabrication and field assembly types are continuously developed to meet increasing environmental protection requirements. Among the assembled basis, the spiral anchor basis uses more, also is comparatively common. However, the spiral anchor foundation can disturb foundation soil in the construction process, and the bearing capacity of the foundation is high in variability. Therefore, the utility model provides a device which can effectively reduce the variation of the basic bearing capacity and increase the bearing performance of the spiral anchor.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a grouting type composite spiral anchor pile foundation, which can enhance the bearing capacity of a spiral anchor, reduce the variability of the bearing capacity of the spiral anchor foundation and reduce the consumption of steel.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:
the utility model provides a compound spiral anchor pile basis of slip casting type, includes the stock and around the rotatory fixed connection anchor disc on the stock lateral wall of stock spiral, still including setting up in the stock inside and extend to the outside high-pressure slip casting pipe of stock, the end of high-pressure slip casting pipe is provided with the high-pressure slip casting hole.
The technical scheme of the utility model is further improved as follows: the anchor disc is provided with one, and the rotatory angle of anchor disc is 360.
The technical scheme of the utility model is further improved as follows: the high-pressure grouting hole is formed in the side wall surface of the anchor rod above the anchor disc.
The technical scheme of the utility model is further improved as follows: the high-pressure grouting holes are symmetrically arranged on two sides of the anchor rod, and at least two high-pressure grouting holes are arranged on the wall surface of one side of the anchor rod.
The technical scheme of the utility model is further improved as follows: the high-pressure grouting holes are formed in the side face of the anchor disc.
Due to the adoption of the technical scheme, the utility model has the technical progress that:
the utility model adopts the end grouting technology, and grouting is carried out in the screw anchor screwing-in process, so that the peripheral soil is fully mixed with grouting liquid to form cement soil from top to bottom, the bearing capacity of the screw anchor is enhanced, and the variability of the basic bearing capacity of the screw anchor is reduced.
The spiral anchor foundation reduces the consumption of steel, only 1 anchor plate at the bottom is needed to be used for the spiral anchor foundation, and the conventional foundation is generally 3-4 anchor plates;
mixed cement soil with the same diameter as that of the anchor disc is formed on the periphery of the anchor rod through high-pressure grouting, so that the bearing performance of the foundation is enhanced;
the uniform cement soil is formed around the anchor rod in the foundation construction process, and the variability of the bearing capacity of the spiral anchor foundation is effectively reduced.
Drawings
FIG. 1 is a schematic view of a cutaway configuration of the present invention;
FIG. 2 is a schematic view of the present invention in use;
the device comprises an anchor disc 1, an anchor rod 2, an anchor rod 3, a high-pressure grouting hole 4 and a high-pressure grouting pipe.
Detailed Description
The present invention will be described in further detail with reference to the following examples:
as shown in fig. 1 and 2, a slip casting type composite spiral anchor pile foundation comprises an anchor disc 1, an anchor rod 2, a high-pressure slip casting hole 3 and a high-pressure slip casting pipe 4, wherein the anchor disc 1 is fixedly connected to the side wall of the anchor rod 2, the anchor disc 1 rotates around the anchor rod 2 in a spiral mode, the anchor disc 1 is only provided with one, and the rotating angle of the anchor disc 1 is 360 degrees.
High-pressure slip casting pipe 4 sets up inside stock 2, and high-pressure slip casting pipe 4 is outside by 2 inside extensions to stock of stock, and the end of high-pressure slip casting pipe 4 is provided with high-pressure slip casting hole 3, and high-pressure slip casting hole 3 pierces through the thickness of 2 side wall surfaces of stock, and high-pressure slip casting hole 3 is located stock 2 outsidely.
There are two positions of the high-pressure grouting holes 3. The first case is that the high-pressure grout hole 3 is provided on the sidewall surface of the anchor rod 2 above the anchor disc 1. The high-pressure grouting holes 3 are symmetrically arranged on two sides of the anchor rod 2, and at least two high-pressure grouting holes 3 are arranged on the wall surface of one side.
The first condition is that the high-pressure grouting holes 3 are arranged on the side surface of the anchor disc 1, the thickness of the anchor disc 1 is thicker, and the inside of the anchor disc 1 is communicated with the inside of the anchor rod 2.
Working principle or using method:
in the construction process, high-pressure grouting is carried out through the high-pressure grouting pipe 4 and the high-pressure grouting hole 3 while screwing in, and peripheral foundation soil is fully scattered and fully mixed with grout through rotation of the anchor disc 1 until the design depth is reached.
