Problems solved by technology

On the one hand, the huge amount of earthwork increases the project investment, on the other hand, it is not conducive to water and soil conservation and civilized construction on the construction site
At the same time, due to the large number of foundations, the construction process is quite cumbersome and the period is very long. The long construction period also affects the overall construction period. For example, the construction period of the foundation sub-project of a 50MWp solar power station is 105 days.
The production method of the above-mentioned improved installation base has not yet been made public

Embodiment 1

[0008] Example 1: Drill vertical boreholes 5 downwards on the ground 3, pour concrete into the boreholes 5, and lower the reinforcement cage 1 to form small-aperture piles. After the concrete pile body 4 reaches strength, the superstructure can be directly constructed Install.

[0009] Use a short auger drill to drill a vertical borehole 5 with a diameter of 300-350 in the ground 3. The depth of the borehole 5 is between 2-3 meters. Then, while lifting the hollow drill bit, pour C30 concrete into the borehole 5. And the small-aperture pile formed by lowering the reinforcement cage 1, the concrete pile body 4 can be directly constructed and installed on the superstructure after reaching the strength. Formwork 2 is installed around the hole 5 upper opening. Template 2 is cylindrical or square barrel-shaped. The upper surface of the concrete in the template 2 is pressed and covered with the top plate 6 . The top plate 6 is a steel plate.

[0010] In this embodiment, the concr...

Abstract

The invention discloses a pile foundation manufacturing method, which comprises the following steps of: downwards drilling the ground 3 to form a vertical drill hole 5; pouring concrete into the drill hole 5; lowering a small-aperture pile formed by a reinforcement cage; and directly constructing the mounting of an upper structure after a concrete pile body 4 has certain strength. A pile foundation is manufactured by pouring the concrete into the drill hole formed by downwards drilling the ground, so the method has the advantages of no ground works generated in the construction, reduced work stages (from conventional six work stages to three work stages), remarkably-reduced concrete consumption, remarkably-shortened construction period which is entirely two-thirds shorter than that of a conventional foundation, remarkably-reduced foundation construction cost which is reduced by 75 percent compared with that of the conventional foundation, simplicity, high piling speed, hole-forming process free from the limitation of geological conditions, pile length which can be flexibly adjusted according to the geological conditions, and applicability to foundation design under various reservoir conditions.

Description

Technical field: [0001] The invention belongs to a method for making and constructing a building installation foundation, such as a method for constructing a foundation supporting an installation frame installed with a solar photovoltaic panel, especially a method for making a pile foundation. Background technique: [0002] In the prior art, the construction method of building installation foundation generally adopts excavation of foundation pit, concrete foundation cushion, steel bar, support formwork, first-stage pouring of concrete foundation, pouring of short concrete columns and pre-embedded parts, backfilling of foundation pit , upper steel frame installation and other processes. For example, the core part of the solar power station - solar panels must be reliably supported on the basis of light steel structures. An independent foundation will lead to a longer construction period, a huge amount of earth excavation and backfill, and a huge amount of concrete engineering...
