No matter what the industry, there is always a sort of seniority, then in the field of steel sheet pile, why is there a Larson steel sheet pile? On the whole, the steel sheet pile is a common name, which includes various types, i.e. Larson steel sheet pile of steel sheet pile is a member of the family, in fact, is provided with a lock sheet pile of steel material, divided into two kinds of hot and cold, from the type of speaking and can be divided into U Z type steel sheet pile, steel sheet pile and a steel sheet pile and so on.
Any product of steel sheet pile may be defective, so it is an essential step to inspect the product before purchase and use. For steel sheet pile, its inspection is generally divided into appearance inspection and material inspection. Through the inspection, it is possible to reject seriously unqualified steel sheet piles and correct minor defects so as to reduce unnecessary troubles during construction.
First of all, the appearance of the inspection, including length, width, thickness, surface defects, the end of the rectangular ratio, flatness and the shape of the lock mouth, and so on. Here are three points: one is the need to pay special attention on the steel sheet pile into the welding parts to cut out; the two is for cutting holes to defect section and reinforcement treatment; three had severe corrosion in steel sheet pile under the condition to measure the actual thickness of its cross section. In principle, the appearance of all steel piles to be used shall be examined before construction.
Then the test material, here is the chemical composition of the steel sheet pile to parent material and mechanical properties of comprehensive inspection. It includes the analysis of the chemical composition of the steel used, the tensile and bending test of the component, the strength test of the lock mouth and the elongation test. For the inspection method, each specification of steel sheet pile should be at least one tensile and bending test; every twenty to fifty tons of steel sheet pile to do two test specimens.
For the storage of steel sheet piles, first is the location choice, on the site, to choose not because of weight will happen parallel place, should choose a relatively flat and solid ground, this is to avoid the steel sheet pile due to self weight deformation, the two is to facilitate the use of more convenient when the steel sheet pile to the construction site.
In addition, the following three points need to be paid attention to: 1. In the pile up, we should take into account the future construction, and properly determine the stacking sequence, position, direction and layout of the steel sheet pile. The first part is placed on the outermost part, and the latter can be placed inside, so that it can be transported easily when used. 2, for different types of steel sheet pile to be separated, can not be piled up, according to different specifications, the length of good classification, and to mark on the stacking place, this is to use can easily find want to use steel sheet pile. 3, the steel sheet pile pile should be piled up in layer, generally each layer of the number of not more than 5, in addition to the layer between the pad on the sleepers, the distance between the sleepers is generally 3 to 4 meters, The advantage of cold formed steel sheet pile lies in its flexibility and to ensure that the upper and lower sleepers should be in the same vertical line, the total height of general pile the case should not be more than two meters.
