Precautions for selecting a door lock
1. Choose a brand with quality assurance. Because the brand manufacturers have after-sales service in various places, free home repair during the warranty period. 2, door thickness: 35-50mm for ball lock, 35-55 mm plug-in, 42 mm mortise lock, 35-55 billiard lock. 3. Center distance: The door lock should be selected according to the structure of the door. The locking tongue can be divided into 60mm and 70mm. The 70mm locking tongue is used for the width of the door bone above 100mm. The 60mm locking tongue is selected below 100mm and above 90mm. 4. Pay attention to the lock that is the same as the opening direction of your door, because the handle lock is divided into left and right handles. 5, in the selection of the handle lock stress, the shape of the handle of each function door lock is consistent, so that the room is more coordinated. 6, hinge: should pay attention to the selection of hinges of sufficient strength, so as not to fall for a long time, resulting in the impact of the opening of the lock, or even broken.The 3D geonet vegetation slope protection technology not only significantly improves the overall and local stability of the slope, but also benefits the growth of slope vegetation. At the same time, the project cost is also low, which is in line with the development direction of slope engineering. Construction process: slope treatment-laying Three-dimensional net-spray planting-surface cover-maintenance management.

1. It can protect earth from being eroded by winds and rains before grass growing up;
2. It can keep grass seeds distributed in slope firmly, and avoid to be washed;
3. Black mat can absorb thermal energy abundantly, increase ground wet, promote seed sprout, and prolong growth term of plants;
4. The surface is tough, so wind and water stream can form plenty of eddy in the surface of the mat, which can produce energy
dissipation function;
5. Plants can form composite protection layer and endure wash with high water and fast speed;
6. It can replace long-lasting slope protection materials such as concrete, pitch, block, etc., and can be used in slope
protection such as road, railway, river, dam, mountain slope, etc.;
7. It can reduce construction cost greatly;
8. It can prevent move of sand dunes after laying sand surface, which can improve roughness of the road surface, increase sediment
of the road surface, change physical performance, and improve partial ecological environment;
9. It is applied in slope protection of road, railway, mine and municipal construction, and it can prevent water and soil loss;
10. First choice of gardening, greening.
