The existing cast-in-place pile construction process includes positioning, hole forming, steel cage placement, concrete pouring, vibration and other processes. The construction process is complicated and the construction efficiency is slow.

[0003] Therefore, how to improve construction efficiency and protect the ecological environment is an urgent problem to be solved. Summary of the invention

[0005] The present invention is achieved by a construction method of microporous cast-in-place piles in photovoltaic engineering, comprising the following steps:

[0006] (1) Mechanical excavation of cast-in-place pile holes;

[0007] (2) placing embedded steel in the pile hole, placing a water-permeable coiled material tube in the space between the outer periphery of the embedded steel and the hole wall, and placing the water-permeable coiled material tube close to the bottom of the pile hole;

[0008] (3) The pile hole is filled with dry aggregate of expansive concrete;

[0009] (4) Water is injected and vibrated through a water pipe connected to the permeable membrane tube to fully and evenly blend the water with the dry aggregate of the expansive concrete, and microporous cast-in-place piles are formed after solidification.

[0010] The material of the water-permeable coiled material tube is PVC floral pipe.

[0011] The top surface of the embedded steel is welded with a square steel plate and fixed to the photovoltaic support.

[0012] Four water-permeable coiled material tubes are evenly arranged along the pile hole.

[0013] The processes of adding the water-permeable coiled material tube and the dry aggregate of the expansive concrete and injecting water are all implemented by robots or intelligent equipment.

[0014] The hole diameter of the microporous cast-in-place pile is 150 mm to 250 mm.

[0015] The advantages and technical effects of the present invention are as follows: pre-prepared building materials are added to the bored pile holes by robots or intelligent equipment, and water is added through water injection pipes, so that the bored piles can be formed efficiently and at low cost by reducing manual operations, thereby improving work efficiency.
