SH3528-2005石油化工钢储罐地基与基础施工及验收规范_附录H条文说明(国外英文资料) SH/T 3528-2005 The appendix H (reference) The can of a can excavate a trench The length of the groove is the circumference of the semicircle, which is the center of the minimum settlement point, which extends the circumference of the circumference by the circumference of the circumference (see figure h. 1). Smin Smax Figure H. 1 ditches length and location The section of the section of the section of the section of the trench is made up of vertical wall (by the side of the wall of the tank) and the outer wall slope (see figure h. 2), the width of the groove is 500 mm ~ 1 000 mm. The ditch wide d is 300 mm ~ 1 000 mm. The soil should be cleared in time and the water in the trench should not exceed the base of the foundation ring wall. one 2 b s. C H3 d Alpha. The h2 a. Note: C is the base of the tank and the ground distance, mm. 1 - tanks; 2 - ring wall Figure h. 2 The minimum distance between the wall of the wall and the wall of the tank can ensure that the sand cushion layer of the foundation in the concrete ring wall is not lost, and the wall of the wall is 300 mm ~ 500 mm. H. 4 groove depth should be according to the soil conditions of tank foundation, wall and tank wall in the distance, load size and length of time and other factors, when the tank foundation is muddy loam, trenching depth can be according to the formula (type H. 1), formula (2) type h. calculation: H3 = h + H2......... (type 1) H. H = s tg alpha...... (type 2) H. Type: H3 - the bottom of the tank to the bottom of the ditch. H -- the calculating factor, mm; H2 - constant, usually 400 mm ~ 500 mm; S -- the distance from the wall of the jar, mm; Alpha - ditch wall slope, take 45 °. The effect of h.5 on the can of the tank. According to the daily subsidence and the amount of time that the earth refills, it is time to make sure that the soil is refilled. After the settlement of the settlement, the settlement of the settlement after the settlement of the
