Description
Technical field
The present invention relates to foundation construction field, in particular to a kind of Composite Bolt stake and its construction technology.
Background technique
In order to reduce influence of the earth excavation to ambient enviroment, currently, reinforced column is widely used in foundation pit work
In journey and Tunnel Engineering.
Existing concrete-pile is divided into prefabricated pile and bored concrete pile.Wherein, there is bored concrete pile without friction, nothing when construction to squeeze
Soil, noise is small, is suitable for the advantages that City Building dense region uses, and relatively broad application is obtained in construction.
As shown in Figure 1, existing bored concrete pile is generally dug in advance in construction is used on the stake holes 1 for placing steel reinforcement cage 2, then
Steel reinforcement cage 2 is placed in stake holes 1, finally the concrete perfusion in stake holes 1, completes the installation of bored concrete pile.Steel reinforcement cage 2 mainly wraps
It includes the more main reinforcements 21 arranged perpendicular to the ground and is set in main reinforcement 21 for fixing the set muscle 22 of 21 position of main reinforcement.
There is a deficiency, exactly when steel reinforcement cage 2 to be placed in stake holes 1, reinforcing bar when in use in above-mentioned bored concrete pile
Certain inclination may occur in stake holes 1 in cage 2, for example, the diameter of steel reinforcement cage 2 is slightly less than the aperture of stake holes 1, so that reinforcing bar
Cage 2 can not be close to hole wall, and in concrete perfusion concrete to steel reinforcement cage 2 there are a promotion, allow steel reinforcement cage 2 in stake
Run-off the straight in hole 1 is poured out the opposite decrease of bending strength of the concrete-pile come after the inclination of steel reinforcement cage 2.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of Composite Bolt stake and its work of constructing
Skill, by installing the locating rod for being supported positioning to the steel reinforcement cage being put into stake holes on steel reinforcement cage, so that steel reinforcement cage
Deviation is not susceptible in stake holes.
Above-mentioned purpose of the invention has the technical scheme that
A kind of Composite Bolt stake, including the steel reinforcement cage being arranged in stake holes, the injecting cement paste being filled in around steel reinforcement cage and and steel
The Grouting Pipe that muscle cage is fixed together；
Steel reinforcement cage includes at least three main reinforcements for being circumferentially equally spaced and being parallel to each other, and is fixedly connected with all main reinforcements more
A be equally spaced is used to be supported the positioning ring of positioning to main reinforcement and be fixedly connected on positioning ring between main reinforcement
With the vertically arranged multiple locating rods of main reinforcement, in the horizontal plane that the same positioning ring and locating rod are formed, locating rod is separate
The edge in the face that one end of positioning ring is formed beyond more main reinforcements.
By using above-mentioned technical proposal, after being drilled stake holes arrangement, completes personnel on site and make steel reinforcement cage, first will
More locating rods weld together with positioning ring, are allowed at locating rod and positioning ring in welding in the same plane；Staff
