Covert projects involve the transformation and installation of water, electricity, and housing structures, and are crucial steps in home improvement projects. The quality of this project is directly related to whether the owners can live comfortably and safely in the future. However, the editorial investigation revealed that there are still many interior design companies in the market that will be involved in the construction of hidden construction projects. As a result, many unfair phenomena will be triggered. We will tell you about common phenomena and coping methods. I hope everyone will quote Take a look.
>>> Links: Common problems and construction priorities for hidden projects
Waterproof project acceptance: Acceptance should be paid attention to, of course, is that the leakage of the waterproof project can not occur.
1. The acceptance personnel shall establish a 15 cm high retaining wall in the entrance to the room for acceptance;
2. We put 10 centimeters of deep water in the room, and we must do a good job of marking the height of the water.
3. After 24 hours, the inspectors checked whether the height of the water surface had changed, and checked whether the ceiling of the room at the same position in the downstairs had seepage.
4. If the above phenomenon does not occur, the acceptance personnel can think that the acceptance of the waterproof construction is qualified; conversely, if the above phenomenon is found through inspection, the construction of the waterproof project can be considered as unqualified. If the acceptance is unqualified, the waterproof project must be reworked and re-inspected; for the acceptance of the light-weight wall waterproof construction, the water-drenching test shall be adopted, even if the water pipe is on top of the waterproof paint wall. Discontinuity spray for 3 minutes. After 4 hours, observe whether the other side of the wall will have a seepage phenomenon. If there is no penetration phenomenon, it can be considered that the wall waterproof construction is qualified.
Tips: For the first step of the ground work, we often say that the closed water test; due to the light wall is prone to leakage phenomenon, and the routine inspection of this part is easy to omit, so to the students out of a small idea.
The acceptance of distribution engineering is to prevent leakage of water, and the acceptance of distribution is to make the line unblocked without short circuit and open circuit.
1, whether the various materials used meet the design requirements;
2. Is the line tube fixed?
3, whether the line pipe connection is firm;
4ã€Whether the wires have joints and joints are firm;
5, whether there is a connector for the TV cable, if any connector must be replaced, or use a disassembler at the connector;
6. If there is a connector on the telephone line, if any connector must be replaced;
7, whether the cassette is installed Founder, whether in the required height;
8. Whether the construction team makes marking on the site where the line pipe is laid;
9, whether the position of the cassette is reasonable, whether the line tube is reasonable, and whether the position of the line connector is reasonable.
Tips: There is another point that should be paid attention to in the distribution and acceptance, that is, the problem of the ground line, the construction personnel should arrange the ground line according to the construction process.
Floor wood keel installation acceptance: It is to make the solid wood flooring laying more stable.
1. Check whether the specifications of wood keel meet the design requirements (generally not less than 2 cm × 3 cm);
2. Check whether the spacing of the wooden keel meets the requirements for the installation of wooden floors (each floor requires at least two keels);
3, check whether the wooden keel loose phenomenon (can step on a step);
4. Check if the plane on the wooden keel is flat (use 2 meters by the ruler);
5. Check whether the gap between the wooden keel and the ground is replaced with a wood wedge instead of a wooden block;
6. Check whether the length of the nails used in the fixed wooden keel can meet the requirements of long-term use, and no loose phenomenon will occur;
7, check whether the high-grade installation meets the design requirements;
8. Check whether there is a telescopic gap at the junction of the wood keel and the wall (to avoid moisture deformation).
Tips: Some people think that solid wood flooring is prone to deformation and its service life is relatively low. However, if it meets the above requirements, the service life will be greatly enhanced.
The acceptance of the construction of the upper and lower water is to prevent the water pipe from being blocked or leaking in daily life.
1. Check whether the water pipes and fittings meet customer requirements (if possible, use good quality water pipes and plumbing fittings as much as possible);
2. Check whether the direction of the water pipe is reasonable, whether there are too many corners, too many joints;
3, check the hose is dead bent, the connection distance is greater than 1 meter (the hose connection distance should be as short as possible);
4. Check for leaks at all joints (visual inspection or use of soft white paper);
5, check the hose is installed at the door (to prevent the water pipe can not be replaced after cracking);
6, the inspection of the water is to take the drainage method.
