Road Maintenance During Rains
Content Brief:
-
The following content is about IE’s highway project site inspection during heavy rain. And passing certain instructions to the concessionaire about maintenance requirements during the monsoon. These instructions have been made to operate safe traffic movements on the highway.
-
This includes sample site reference notices to the concessionaire by IE about issues on the subject matter. It summarises the various instances of rain and the problems caused by them. Besides that, appropriate mitigation measures were suggested by the independent engineer upon the issues.
-
It provides comprehensive details of various issues along with a photographic presentation.
Purpose of Inspection and Road Maintenance During Rains:
-
It is that, during rainy times, the road and bridge structures are vulnerable to damage.
-
Any flaws in the highway will become obvious.
-
And, thus, deficiencies in the project highway will be more pronounced.
-
Inspections during this time are critical to check how well the structures are doing.
The following are the various instances found in the inspection and instructions to concessionaires on road maintenance during rains.
Road maintenance during rains, (case 1)
Stagnation of rainwater was observed on the main carriageway at Km. 10+160RHS. It has to be drained of the rainwater stagnation from the carriageway and its associated elements for safe and uninterrupted traffic movements on the highway. Road maintenance during rains, (case 2)
Road maintenance during rains, (case 3)
Road maintenance during rains, (Case 4)
Due to heavy rain, several trees fell on the roads at Chainage km. 117+700, 145+950, 156+950,162+900 and many other isolated locations on the highway. Clearing the carriageway as much as possible for uninterrupted flow of traffic and ensuring that drivers on the project highway are unobstructed. And it is to ensure that the carriageway and its associated elements are free of obstructions. Road maintenance during rains,(Case 5)
It is that at certain locations, the surface runoff and rainwater at the abutting ground are standing still. It is to the height of the finished carriageway level. To keep constant vigil at all such locations for any progression of water into the Way and with means to arrest any occurring upon such. Road maintenance during rains, (Case 6)
Between chains 20 and 21/500, surface runoff water is flowing in wide widths upon the earthen shoulder and adjacent to it. Sometimes encroaching upon the BT surface. It is to make as simple flow chutes as possible to drain the water and ensure there are no distractions for drivers. Road maintenance during rains (case 7)
Barricades are grounded in most places and seem hazardous. Steps are taken to remove them without harming road users. Road maintenance during rains, (case 8)
At other access locations, the ground between the carriageway and the access is being formed. Please initiate actions to relieve such conditions immediately. Road maintenance during rains, (case 9)
To ensure that the drain of surface runoff is made permanent by conducting frequent maintenance at km. 17 This is for safe, smooth, and easy operations. Yesterday, the maximum hours of manpower deployment were observed at this location. Road maintenance during rains (case 10)
From km. 41+700 to 41+900 BHS, all the rank vegetation, foreign material, debris, and soil piles adjacent to the carriageway elements shall be removed. The earthen shoulder is to maintain a clean, orderly condition at the level of the carriageway. It will be maintained in a trafficable condition at all times in all weather conditions. Further, ensure the function of the earthen drain in relation to the surface runoff discharge requirements. The undertaken actions and initiations upon the noticed defects shall comply by the end of the day. Road maintenance during rains (case 11)
At chainage 17+700, 45+950, 56+950,62+900 and many other isolated locations on the highway, surface runoff water is standing still or encroaching upon the BT surface. It is to make as simple flow chutes as possible to drain the water and ensure there are no distractions for drivers. Shall ensure that no water stagnates upon the paved, earthen shoulders and those adjacent to it. Road maintenance during rains (case 12)
At km. 39+300 RHS, It is to make sure that, to prevent possible splashing of water stagnations by traffic flows, it is to opt for other locations for routine maintenance activities until the clearance of water stagnations. As observed, partial lane closures are in force at these locations for median plant pruning and grass trimming, indicating that the lane availability is too sparse. Be guided by the site supervisors on what makes it better to maintain the level of service on the highway. at this kind of hurdle. Road maintenance during rains (case 13)
It is ascertain that, find the root cause for such stagnations at km.125+200 and rectify. Is this the location required any profile corrections is to be ensured. Road maintenance during rains (case 14)
As observed, the abutting ground level of all these water stagnation areas adjacent to the carriageway profile is too high. Also, poor maintenance of surface runoff discharge requirements, abrupt loss of edge drops or shoulder depths greater than 40 mm/soil piles, and damaged conditions. All these defects and flaws should be rectified with appropriate plans and procedures for permanent beneficiaries and non-recurring projects. Independent Engineer Suggestions to the Site Team on Road Maintenance During RainsIt is observed that rainfall is heavier from ch. 15 onwards to the project end. To augment additional resources all around the clock for ready action at any incidents. It is the general tendency of drivers to halt in this inclement condition. To see that the park’s all are well outside the traffic plying zone of the carriageway. I.e., please make sure that the parking of vehicles is well within paved shoulders only. It means any parking should be away from carriageway lanes. |
