1. In addition to meeting the requirements of earth rock excavation, the engineering geological data of deep cutting sections and cutting slopes determined in the design drawings shall be reviewed in detail before construction, and an implementation construction plan shall be prepared. 2. Since the slope of deep cut is high and it is difficult to control the slope rate, it is necessary to measure and set out the groove pile at the groove position before construction, and dig a 0.2m × 0.2m groove along the groove after review (if the rock is exposed, use red paint and other marks) to prevent slope dislocation during construction. 3. Drainage work shall be done in time during construction, intercepting ditch shall be excavated according to design requirements, paving work shall be completed as far as possible, and surface water shall be intercepted. For sections prone to landslide and collapse, strengthen observation and take protective measures in time. 4. According to the terrain of the site, the following two excavation schemes are adopted: (1) When the longitudinal terrain of the deep excavation section along the route is relatively gentle, dump trucks and excavators are used for direct excavation. The construction access road shall be opened along the route direction, and the longitudinal slope of the access road shall ensure that the empty dump truck can smoothly climb to the top of the slope under normal conditions. For construction safety, a construction access road shall be opened on the left and right sides of the route, and the vehicles shall be driven separately. Excavators shall excavate in layers and layers from high to low. The depth of each layer shall be controlled within 3~4m, and the width of each layer shall be controlled within 8~10m.

some expressway Subgrade sand filling construction
In the first phase of the expressway project, a 12km high fill road base fell on the ancient river channel on the south side of the Hutuo River and the yoke bend formed by the flood. There was a large amount of alluvial fine sand in the river channel, but there was no cohesive soil or other suitable filling materials in the short distance, which caused great difficulties in the subgrade filling. In addition to the permanent occupation of a large amount of land resources, the construction of expressways also requires a large amount of cultivated land for high fill subgrade borrowing. For a country with a small per capita area of cultivated land, such as China, it does bring many problems that are detrimental to the country and people. How to occupy as little farmland as possible, save fertile land and save investment has become an important topic in highway construction. Sand soil has good water stability, strong water permeability, fast settlement, easy compaction when saturated with water, and small capillary rise height, so it is a good subgrade filling material. Road construction and subgrade filling with river sand in the beach sandy soil section of inland China can not only dredge the river channel, but also occupy less arable land, use local materials and reduce the cost. However, as filling material, sand is easy to slide and collapse after water loss, difficult to compact, and has poor dry stability. The advantages of the two materials can be brought into play by adopting the filling method of sand core, clay edge, and soil sand.
