37.0 Machine bases
..After completion of the blinding layer under the machine base,construct a 115mm brick
or 100mm concrete block wall around the edge of the base as permanent formwork,and
carry this up to the level of the underside of the ground floor slab.
Continue with timber formwork above this level as required.Line the vertical faces to
the top of the ground floor slab with 50mm expanded polystyrene or polyethylene,
otherwise as specified in clause 31.0.Lay 75mm wood wool slabs on the blinding layer
and cover this with PVC sheet.Pour the machine base monolithically.Allow for fixing
bolts as follow:
a.Cast bolts in position with a washer over the head and surrounded by a steel tube
with an internal diameter twice that of the bolt;
b.Provide a hole for grouting the bolt into position.Formwork for the hole is to be
either of timber and so designed that it can be easily removed,or of expanded
polystyrene and subsequently burt out with a below lamp.The top edge of the
joint around the base is to be provided with a floor joint cover as specified under
clause 31.0.
38.0 Well kerbs
..Construct well kerbs,where required of concrete grade III (1:2:4 o.g.) 280mm x 480mm
splayed in cross section and of the requisite diameter,reinforced with 4 No.13mm
diameter steel rods with 6mm diameter stirrups at 225mm centres.The kerb is to be
placed in position and sunk by the weight of brickwork during the excavation.

37.0 机器基座
在机器基座的基础垫层完工后,要沿基座建造一个115mm的砖结构或者100mm的混凝土块结构的墙用来作为永久性构架,砌墙高度与下侧的地面上的水泥板高度相同.
之后,再在该结构上建造木质构架,其高度要满足要求.在从地面水泥板以上的垂直表面上加以弹性聚苯乙烯或者聚苯乙烯,再或者参照条款31.0中的要求进行建造.在基础垫层上铺质75mm的刨花板,并在其上覆盖以PVC材料层.机器基座要灌注成完整的一体.对于膨胀螺栓的安装要求如下:
1.箱体膨胀螺栓的位置上要加上垫圈并且套在一个内直径为膨胀螺栓直径两倍的钢管内.
2.在安装膨胀螺栓的位置提供一个膨胀螺栓的灌浆孔.该孔的构架可以采用木质结构,并且要设计成较容易取出的结构,或者采用弹性聚苯乙烯,随后在下部装设照明灯具.基座周围的最上边缘的连接处应该与地板处相连接,其具体要求参照条款31.0
38.0 井的砌砖墙
建造井的砌砖墙,该处要求用混凝土等级III(1:2:4 o.g.)在交叉部分来造一个280mm x 480mm的斜面,该斜面满足要求所必需的直径,同时用4跟直径为13mm的钢杆加上直径为6mm的箍筋距离中心处225mm的地方进行支撑.该井 砖砌墙应在挖井过程中的相应位置进行铺制,并且用砖结构的重量进行沉压.
