Example 2, application example of the composite material of the present invention-pole crash protection squat.
At present, a plurality of electric poles are integrally made of steel pipes, and are easily collided by automobiles when traffic accidents happen, so that not only can serious traffic accidents be caused, but also the electric poles can be seriously collided to cause the interruption of power transmission. Therefore, the firm stability of pole needs to be strengthened, generally is to install the anticollision fender mound additional in the bottom of pole and protects the pole. However, the common anti-collision pier is mainly built by bricks, concrete or stones, and although the anti-collision pier can play a strong role in isolating and protecting the electric pole, the hard anti-collision pier hardly has any buffer effect on the vehicle, and once the anti-collision pier is collided, serious accidents can be caused due to the overlarge rigidity of the anti-collision pier.
The material disclosed by the invention is filled in a buffer area of the anti-collision squat protection of the telegraph pole to serve as a soil-based buffer material, and the soil-based buffer material comprises the following components in parts by weight: the composite material is prepared by adding 18 parts of water, 2 parts of cassava starch, 3 parts of inorganic aqueous adhesive cement and 5 parts of self-warming quick-setting adhesive powder into 100 parts of fly ash and slag powder, 12 parts of steel slag crushed stone, 3 parts of bentonite, 2 parts of attapulgite, 10 parts of crushed rice and/or crushed straw and/or wood chip material, rapidly stirring and uniformly mixing, then heating, cooling and molding.
Slag and waste material crushed aggregates used in the buffer are common visible substances, are crushed and then are uniformly mixed with special adhesive, and are filled into an anti-collision squat buffer area, so that a high-strength and tough soil alloy can be formed after solidification, and the buffer is free of steel, corrosion, rustiness, moisture, water and fire, hard and durable, and waste materials are changed into valuable substances.
The above description is only presented as an enabling solution for the present invention and should not be taken as a sole limitation on the solution itself.
