Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
As shown in fig. 1 and 2, a method for constructing a support pile based on a mortise and tenon structure includes the following steps:
the method comprises the following steps: adopting a manual hole digging pile and mechanical hole forming mode to cast and construct a vertical retaining pile 1 of the supporting pile on site, and casting a tenon 3 model on the top of the retaining pile 1; meanwhile, a transverse crown beam 2 of the support pile is prefabricated by adopting a prefabricated part process, and a mortise and tenon matched with the tenon is formed on the crown beam 2. In the present embodiment, the tenon 3 is preferably cast into a trapezoidal platform-like structure, and the lower part of the mortise joint 4 is configured into a trapezoidal hole shape.
In the first step, the pouring of the retaining pile 1 and the pouring of the tenon 1 can be completed by one-step pouring construction or can be performed by two-step pouring construction step by step. No matter which kind of pouring mode, must require the inside reinforcing bar of tenon and the inside reinforcing bar ligature of fender stake as an organic whole. When adopting the hierarchical pouring, 1 top in fender pile sets up the net reinforcing bar, and the inside reinforcing bar of tenon is pre-buried the ligature on the net reinforcing bar.
Step two: and hoisting the prefabricated crown beam 2 to the top of the retaining pile 1, and buckling the mortise joint 4 of the crown beam on the tenon 3 at the top end of the retaining pile. Tenon 3 and trapezoidal hole molding's fourth of the twelve earthly branches interface 4 of trapezoidal platform column structure not only can realize quick installation, but also can play from aligning effect, ensure that the crown beam is put down and is gone to the position of predesigned promptly, shorten later stage correction time. The method has the advantages of high construction efficiency and reliable construction quality. In the present embodiment, a single crown beam 1 spans at least two retaining piles 2, namely: the crown beam can be a one-span prefabricated crown beam or a multi-span prefabricated crown beam.
In the second step, before the crown beam is hoisted, a control line is marked on the retaining pile 1 and the crown beam; and when the tenon and the prefabricated crown beam concrete reach certain strength, hoisting the crown beam in place by adopting hoisting equipment, and correcting according to the marked control line.
Step three: and after the hoisting of the crown beam is finished, plugging the mortise joint from the upper surface of the crown beam. In this implementation, the lateral part all around of tenon 3 all pours the shaping and has the first spread groove 5 that extends along the direction of height, all is equipped with second spread groove 6 on the pore wall all around of fourth of the twelve earthly branches interface 4, and after the crown beam hoist and mount, second spread groove 6 is just right with first spread groove 5 one by one to the degree of depth of fourth of the twelve earthly branches interface 4 is greater than the 3 heights of tenon. When the mortise joint 3 is plugged from the upper surface of the crown beam, the plugging filler can be filled in a space surrounded by the first connecting groove 5 and the second connecting groove 6, and the upper part of the mortise joint 4 can be completely plugged to be flush with the surface of the tubular beam, so that the crown beam and the retaining pile are effectively drawn into an integral structure, and the supporting strength is better. In the implementation, the mortise joint plugging filler is made of high-strength micro-expansive concrete or high-strength mortar. And maintaining in time after the mortise joint is plugged.
Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
