土木工程中对于挖掘机的使用要注意什么?

日期:2020-09-28   来源:
(1)根据土方工程开挖深度和工程量的大小,选择机械和人工挖土或机械挖土方案。
(1) According to the excavation depth and quantity of earthwork, mechanical and manual excavation or mechanical excavation scheme are selected.
(2)如开挖的基坑(槽)比邻近建筑物基础深时,开挖应保持一定的距离和坡度,以免在施工时影响邻近建筑物的稳定,如不能满足要求,应采取边坡支撑加固措施。并在施工中进行沉降和位移观测。
(2) If the foundation pit (trench) excavated is deeper than the foundation of adjacent buildings, a certain distance and slope shall be kept during excavation to avoid affecting the stability of adjacent buildings during construction. If the requirements cannot be met, slope support reinforcement measures shall be taken. The settlement and displacement are observed during the construction.
(3)弃土应及时运出,如需要临时堆土,或留作回填土,堆土坡脚至边坡距离应按挖坑深度、边坡坡度和土的类别确定,在边坡支护设应考虑堆上附加的侧压力。
(3) The spoil shall be transported out in time. If it is necessary to temporarily pile up soil or reserve it as backfill, the distance from the toe of the pile to the side slope shall be determined according to the excavation depth, slope gradient and soil type. The additional lateral pressure on the pile shall be considered in the design of slope support.
(4)为防止基坑底的土被扰动,基坑挖好后要尽量减少暴露的时间,及时进行下一道工序的施工。如不能马上进行下一道工序,要预留15cm~30cm厚覆盖上层,待基础施工时再挖去。

(4) In order to prevent the soil at the bottom of the foundation pit from being disturbed, the exposure time should be reduced as much as possible after the excavation of the foundation pit, and the construction of the next process should be carried out in time. If the next process cannot be carried out immediately, the upper layer should be covered with a thickness of 15cm ~ 30cm, which can be excavated after the foundation construction.
基坑开挖要注意防止因基坑被浸泡,引起坍塌和滑坡事故的发生。为此在制定土方施工方案时应注意采取措施。
In the excavation of foundation pit, attention should be paid to prevent the occurrence of collapse and landslide due to the soaking of foundation pit. Therefore, measures should be taken when formulating earthwork construction scheme.
(1)土方开挖及地下工程要尽可能避开雨季施工,当地下水位较高、开挖土方较深时,应尽可能在枯水期施工,尽量避免在水位以下进行土方工程。
(1) Earthwork excavation and underground works shall avoid rainy season construction as far as possible. When the underground water level is high and the excavation earthwork is deep, the construction shall be carried out in dry season as far as possible, and earthwork below the water level shall be avoided as far as possible.
(2)为防止基坑浸泡,除做好排水沟外,要在坑四周做挡水提,防止地面水流入坑内,坑内要做排水沟、集水井以利抽水。
(2) In order to prevent the foundation pit from soaking, in addition to the drainage ditch, the water retaining lift should be made around the pit to prevent the surface water from flowing into the pit. The drainage ditch and water collecting well should be built in the pit to facilitate pumping.
(3)开挖低于地下水位的基坑(槽)、管沟和其它挖土时,应根据当地工程地质资料,挖方深度和尺寸、选用集水坑或并点降水。
(3) When excavating the foundation pit (groove), pipe trench and other excavation below the underground water level, the excavation depth and size shall be selected according to the local engineering geological data, and the sump or point precipitation shall be selected.
