Cement pipe pile for reinforced photovoltaics using recycled concrete and preparation method thereof

Abstract

The invention discloses a cement pipe pile for reinforced photovoltaics using recycled concrete and a preparation method thereof. The cement pipe pile comprises the following components: recycled coarse aggregate, recycled fine aggregate, a cementing material, a preservative, an expansion agent, an early strength agent, a water reducer, an auxiliary agent and water. The preparation method of the cement pipe pile comprises the following steps: preparing recycled coarse aggregate and recycled fine aggregate; carrying out carbonization treatment; determining slump and preparation strength; mixingand stirring raw materials to obtain recycled concrete; placing the recycled concrete into a mold, stretch-drawing, carrying out centrifugal molding; maintaining, and demoulding to obtain the cementpipe pile using the recycled concrete. By using the recycled aggregates as the raw materials of the cement pipe pile, costs are reduced and the environment is protected. With reasonable matching of the raw materials, the cement pipe pile has excellent compressive strength and anti-cracking ability, and has good corrosion resistance and durability. The preparation process of the cement pipe pile issimple and is easy for large-scale production.

Description

technical field [0001] The invention relates to the technical field of photovoltaics, in particular to a reinforced cement pipe pile for photovoltaics using recycled concrete and a preparation method thereof. Background technique [0002] With the acceleration of industrialization and urbanization in our country, the accompanying construction waste is increasing, and the amount of construction waste in my country has accounted for more than 1 / 3 of the total urban waste. However, the vast majority of construction waste is transported to the suburbs or villages without any treatment, and is stacked in the open air or landfilled, consuming a lot of construction expenses such as land acquisition fees, garbage removal and transportation costs, and at the same time, the waste and waste in the process of clearing and stacking Dust, dust flying and other problems have caused serious environmental pollution. [0003] Recycled aggregate concrete, referred to as recycled concrete, is ...

Problems solved by technology

At present, the most commonly used photovoltaic power plant pipe pile foundations in the market are high-strength prestressed pipe pile foundations. High-strength prestressed pipe pile foundations have the advantages of good construction flexibility, but they have low compressive strength, easy corrosion, poor durability, Concrete is not compacted and easily cracked, resulting in poor pile quality. Therefore, it is necessary to develop a concrete pipe pile with high strength, corrosion resistance, good crack resistance, good pile quality, and low cost.
