1. Introduction to flood control straw bags.
Flood control straw bag is an emergency tool used for flood control, usually made of woven grass, with certain waterproof performance and load-bearing capacity. Before the flood season, people usually prepare a certain number of flood control straw bags in case of emergency.
Second, the installation steps.
1.Prepare tools and materials.
Before we start installing flood control straw bags, we need to prepare the following tools and materials: weaving grass, scissors, rope, buckets, gloves, etc. Make sure all tools and materials are ready so as not to affect the installation schedule.
2.Divide into regions.
According to the situation of the site, the area that needs flood control is divided into several blocks, and the size of each block can be determined according to the actual situation. When dividing the area, it is necessary to take into account the topography of the site, the direction of the water flow and other factors to ensure that the flood control straw bag can fully function.
3.Lay the bottom mat.
Before installing the flood control straw bag, it is necessary to lay the bottom mat. You can choose some water-resistant materials for the bottom pad, such as plastic sheeting, wooden boards, etc. The purpose of laying the bottom mat is to protect the foundation from water soaking and also to provide a stable support for the flood control bags.
4.Fill straw bags.
Place the woven grass in a bucket in order and use gloves to pull it out and weave it into a straw bag. In the process of filling the straw bag, it is necessary to ensure the tightness and integrity of the straw bag to avoid water leakage. At the same time, it is necessary to pay attention to controlling the filling speed to avoid the straw bag from expanding too quickly and breaking.
5.Lay straw bags.
Lay the filled bags one by one in the divided area, making sure that each block is covered. When laying straw bags, it is necessary to maintain a certain degree of tightness to avoid water penetration. At the same time, it is necessary to pay attention to the direction of the water flow, and adjust the laying speed and position according to the speed and direction of the water flow.
6.Attach the straw bag.
When two adjacent straw bags need to be attached, a rope needs to be used to secure them together. The length and position of the rope should be reasonable to ensure the tightness and stability of the joint. When attaching the straw bags, care should be taken to avoid damaging the straw bags, and at the same time, it is also necessary to pay attention to the direction of the water flow to avoid affecting the speed and direction of the water flow.
7.Inspection and reinforcement.
After the completion of the laying, the flood control straw bags should be inspected to ensure that there is no leakage, damage and other phenomena. If any abnormalities are found, they need to be patched and reinforced in a timely manner. Reinforcement can be done by increasing the density of the rope, using additional straw bags, etc.
8.Evacuate the scene.
After the flood control work is completed, it is necessary to evacuate the scene in time to ensure the safety of personnel. Before evacuating, all tools and materials should be sorted out to ensure that they are not left on site. At the same time, the site should be cleaned up to ensure that there is no impact on the surrounding environment.
In short, the installation of flood control bags needs to be carried out according to certain steps, including preparing tools and materials, dividing areas, laying bottom mats, filling straw bags, laying straw bags, connecting straw bags, inspecting and reinforcing and evacuating the site. During the installation process, it is necessary to pay attention to safety and follow the operation specifications to ensure the smooth progress of flood control work.
