Drilling toolsSummarize the attention factors of manual digging pile:Site management personnel shall carefully explain the geological conditions and groundwater conditions of the excavated pile to the construction personnel, and propose possible problems and emergency treatment measures. Sufficient mental preparation and sufficient materials and machinery for emergency measures shall be prepared. Safety measures should be formulated and checked and implemented frequently.

First of allUnder the holeWorkNo.CanMore2 persons shall wear safety helmet, raincoat, rain pants and long rain boots during operation. Operators under the hole and personnel on the hole shallGuaranteecontact signalunobstructed. Hammers, hoes, stones and iron bars shall not be placed around the ground. Every job1h, underground personnel and ground personnel exchange.

There are many potential safety hazards in manual digging. The social development is getting faster and faster. ModernDrilling toolsMore and more.

SecondlyUnderground personnel should pay attention to observe the changes of hole wall. Support measures shall be taken in time if collapse or cracks are found. If there is any danger, the contact signal should be sent out in time so as to evacuate quickly. And take effective measures to eliminate the danger as soon as possible.

Ground personnel should pay attention to the contact signal under the hole and respond quickly. Always check whether the bracket, pulley and rope are firm. When hanging down, hang it firmly, and pour the earth and rock lifted up clean and unload it at the orifice.Outside 2m.

During the construction of pumping, lighting, ventilation and other power distribution equipment should be one machine, one brake and one leakage protector, power supply lines should use three-core rubber lines, wires should be overhead, not dragged on the ground. And often check whether the wire and leakage protector are in good condition,When pumping water from the hole, the drain should be located away from the orifice.More than 5m, and ensure the smooth drainage of the construction site.

ModernizedDrilling toolsIt can ensure personal safety and make construction easier and easier.

FinallyThe hole was dug on the same day and the wall was poured on the same day. When people leave the construction site, the orifice shall be covered and obvious warning signs shall be set up when necessary.

Since there may be humus in the soil layer or the gas generated by the humus in the neighborhood escapes into the hole, it is necessary to prevent the harmful gas in the hole. Before the construction personnel and inspectors go down the holeOpen the hole cover within 10min. If there is any abnormal smell, it shall be reported to relevant departments in time to remove harmful gas before operation. Hole digging6~10mDeep, ventilating the hole at least daily1times, more10mVentilate at least every day.2Second, if the workers under the hole feel that they are not breathing smoothly, they should also ventilate in time.

There are many brands of drilling tools in contemporary society, ShijiazhuangWeitarProbing drilling machinery productionFriction welding drill pipe, There are various specifications, the length and the width of the hole can be customized to meet the needs of different customers.
