Question 2: What's the difference between slope and slope protection? 15: A slope is a slope, and a slope protection is something that protects the slope, such as the anchor and shotcrete support outside the earthwork slope!
Question 3: What does the slope protection ratio in expressway mean? It refers to the ratio of the projection length of the slope in the horizontal direction to its projection length in the vertical direction, which is opposite to the attack direction of the slope. The slope coefficient is expressed by k, that is, K=b/a, earthwork slope =H/B (foundation pit height/slope width), and then the slope coefficient (in the norm) = 1/(B/H).
After the completion of subgrade earthwork, subgrade slope protection works include plant protection and masonry protection (such as slope protection, face protection wall and retaining wall). There is also the combination of plants and masonry protection, such as overlapping arch protection, which needs to choose different protection forms according to different slope types, failure possibility and influence degree.
The role of slope protection:
(1) Restore the destroyed ecological environment.
(2) Reduce noise and light pollution.
(3) Promote the degradation of organic pollutants, purify the atmosphere and adjust the microclimate.
Question 4: What is the protection of slope protection in construction projects?
Question 5: What is the difference between slope protection and retaining wall? Retaining wall refers to the structure that supports subgrade fill or hillside soil to prevent deformation and instability of fill or soil. On the cross section of the retaining wall, the part that directly contacts with the supported soil is called the back of the wall; The part opposite to the back of the wall and facing the air is called the wall; The part in direct contact with the foundation is called the basement; The top surface of the wall opposite to the basement is called the top of the wall; The front end of the basement is called the wall root; The rear end of the base is called the heel.
Slope protection refers to all kinds of paving and planting on the slope to prevent the slope from being washed away. In the reach where the bridge site is located, the concave bank of the river bank is washed away by the current year by year, which will make the river bank collapse continuously. In order to protect the safety of bridges and dikes, protective buildings must be built on concave banks. In addition, when the river changes its flow direction due to the bridge, scouring the bank and endangering farmland and villages and towns, protective buildings must also be built on the bank.
Question 6: What do you mean by the bank slope of1to 0.5? When the vertical direction drops 1m, the horizontal direction moves to the center of the river by 0.5m This slope is much steeper than 45.
Question 7: What is a berm?
The berm is a platform with a width greater than 1~2m or 4m reserved between the toe of subgrade slope and the top of borrow pit to protect subgrade slope from water erosion and ensure slope stability.
Question 8: What's the difference between slope protection and bank protection? Slope protection refers to the part above the low water level, and bank protection broadly includes slope protection and underwater bank protection.
Question 9: Forms of engineering slope protection The forms of engineering slope protection include: dry rubble concrete block slope protection, mortar rubble concrete slope protection, lattice slope protection, sprayed concrete slope protection, paving slope protection, etc.
The revetment project is divided into two parts according to the average low water level of the river for many years, that is, it is called "slope protection project" above the low water level and "foot protection project" below the low water level. In order to prevent collapse, it is more labor-saving and faster to build a slope protection project directly on the slope surface for reinforcement than to cut the slope.
Question 10: What does slope protection mean? Slope protection: facilities laid to prevent bank slope erosion.
