马头门参数的计算,主要是指马头门高度的计算。是井底车场设计中经常遇到的问题。很多作者进行了研究,总结出不少计算方法。 1.作图法:把一条等于该井筒所下放长材料长度L的直线,放在直角座标内,使一端沿纵轴移动,另一端沿横轴移动,当直线由垂直于横轴的位置,移成平行于横轴的位置过程中,始终不与马头门的顶部相撞,则马头门的高度H就能满足下放长材料的要求。这种方法直观、简单、可靠,是在现场实际中常用的方法。
Matoumen parameter calculation, mainly refers to the calculation of Matou door height. It is often encountered in the design of underground parking lot. Many authors have studied and concluded a lot of calculation methods. 1. The drawing method: a length equal to the length of the wellbore L under the L, placed in a rectangular coordinate, so that one end along the vertical axis, the other end along the horizontal axis, when the straight line from the vertical axis of the position , Moved into a position parallel to the horizontal axis, always does not collide with the top of the horse head door, then the height of the horse head door H can meet the requirements of the release of long material. This method is intuitive, simple and reliable and is a commonly used method in the field.
