硬塑的粉质黏土、黏土坡顶无荷载时按1:0.33坡度放坡开挖，由于缺少地

硬塑的粉质黏土、黏土坡顶无荷载时按1:0.33坡度放坡开挖，由于缺少地质资料，本工程按1:0.33坡度开挖估算土方量。具体开挖放坡系数根据实际地质按照《给水排水管道工程施工及验收规范》中要求。放坡埋管后采用级配碎石填沟槽，当管顶到路床顶面的高度≤80cm时，直接用级配碎石回填至路床顶面，当管顶到路床顶面的高度＞80cm时，管顶以上50cm回填级配碎石，再用素土回填至地面，回填均需分层压实，每层厚度200mm。具体详见设计图。
(2)沟基基底承载力不小于120KPa。若遇流砂、淤泥、松散杂土及回填等软弱地基时应联系设计单位出加固方案，使之达到设计要求的地基承载力。

結果 (英文) 1:

Hard plastic silty clay and clay, the top no load on a 1:0.33 slope-slope excavation, due to the lack of data measured over the 1:0.33 slope excavation of earthwork of the project. Specific excavation slope coefficients based on actual geological in accordance with the water supply and sewerage pipeline engineering construction and acceptance specification of requirements. Put slope buried tube Hou used level distribution gravel fill Groove, dang tube top to road bed top surface of height ≤ 80cm Shi, directly with level distribution gravel backfill to road bed top surface, dang tube top to road bed top surface of height >80cm Shi, tube top above 50cm backfill level distribution gravel, again with sutu backfill to ground, backfill are needed layered pressure real, each layer thickness 200mm. As detailed in the blueprints. (2) the Groove base bearing capacity of not less than 120KPa. If impurity drift sand, mud, loose soil and backfill soft soil Foundation reinforcement design units should contact the programme, so as to meet the design requirements of the Foundation bearing capacity.

結果 (英文) 2:

Hard plastic silty clay, clay top of the hill by 1:00 no load: 0.33 slope grading excavation, due to lack of geological data, the project of 1: 0.33 slope excavation earthwork estimates. Specific Excavation grading coefficient according to the actual geological accordance with the "water drainage pipeline engineering construction and acceptance" in the requirements. After grading pipe using graded gravel to fill the trench, when the tube top to the top surface of the road bed height when ≤80cm, graded gravel backfill directly to the top surface of the road bed, when the tube top to the top surface of the road bed height> is 80cm, 50cm tube top over graded gravel backfill, then prime soil backfill to the ground, need to be stratified backfill compaction, thickness of each layer 200mm. Specific detailed design.
(2) trench based substrate carrying capacity of not less than 120KPa. In case when the flow of sand, mud, loose soil and backfilling miscellaneous soft ground contact design units of reinforcement scheme, so as to meet the design requirements of the foundation bearing capacity.

結果 (英文) 3:

The excavation of hard plastic silty clay and clay slope without load by 1:0.33 slope slope, due to the lack of geological data, the engineering calculation of earthwork excavation slope by 1:0.33. According to the actual geological in accordance with the actual geological conditions of the slope coefficient of excavation in accordance with the "water supply and drainage pipeline engineering construction and acceptance norms". The slope of buried pipe by the gradation crushed stone filling groove, when the tube top to the top of the road bed height is less than or equal to 80cm, the direct use of gravel backfill to the roadbed top surface, when the tube top to the top of the road bed height was more than 80cm, 50cm above the top of pipe backfill gravel, soil and backfill backfill shall be stratified to the ground compaction, the thickness of each layer 200mm. Specific details of the design.(2) the foundation bearing capacity of the channel is not less than 120KPa. If the flow of sand, silt, clay and other miscellaneous loose backfill soft foundation should be linked to the design unit of reinforcement scheme, so as to meet the design requirements of the bearing capacity of foundation.
