Problems solved by technology

But then it was discovered that during the storage and transportation of the corrugated beam slabs, the small wooden blocks and straw ropes deformed rapidly under long-term heavy pressure, the gap between the corrugated beam slabs decreased, and the two sides of the slabs were in close contact. The bumps and vibrations in the environment will intensify the friction between the plates, causing the coating on the contact parts to be scratched, peeled off, and even the steel substrate is also worn and scratched; The friction between the iron wire and the board will quickly damage the plastic layer of the barrier, and the direct friction between the iron wire and the coating of the board will easily cause the coating to be damaged. These will bring unnecessary troubles to the construction unit. Serious hidden dangers for corrosion protection due to coating damage

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 , figure 2 Shown: Put a piece of expressway corrugated beam slab (nine-hole standard slab) that has been painted off the assembly line on the sleeper 2 (it is convenient for transshipment or forklift by wearing a sling, and also avoid direct contact with hard objects on the ground to prevent damage to the coating) , in the groove of its both sides leaning against board respectively puts five long pieces of wood chips 3, the size of long wood chips is long * wide * height (thick) 120mm * 25mm * 7mm, about 900mm mutually intervals. Then stack the second board, place the same number of long pieces of wood at the same position and then put the third board... Such as image 3 As shown, after putting the tenth board, such as Figure 4 , Figure 5 As shown, pass the 8# iron wire 5 (double strand) wrapped with plastic tape through ...

Abstract

A method for packing the painted corrugated beam plates used for express way includes such steps as laying one corrugated beam plate on sleepers in such manner that its front surface is in contact with sleepers, inserting the rectangular wooden boards in the valleys at both ends, stacking others in the same way, passing steel wires through the holes on the beam plates, putting the soft pad between beam plates and steel wires, and tightening the steel wires.

Description

technical field [0001] The invention relates to a packaging method for highway guardrails, in particular to a packaging method for coated expressway corrugated beam plates. The invention belongs to the packaging technology field of the coating processing industry. Background technique [0002] In order to meet the needs of the rapid development of the national economy, the scale of expressway construction in our country is constantly expanding. After more than ten years of construction, China's expressways have broken through 35,000 kilometers from scratch, and the total mileage of expressways ranks second in the world. Since 2001, the Ministry of Communications began to formulate the "National Expressway Network Plan" as the guiding outline for expressway construction in the next 20 to 30 years. The national expressway network (referred to as "7918 network") adopts the layout form of the combination of radial lines and vertical and horizontal g...
