The construction party buried the damaged pipeline embedded pipe, and only found out after the warra

If you find out after the expiration date, it is best to suggest that you can communicate and coordinate effectively with the relevant parties.

In a scientific, safe and reasonable way, effective maintenance and treatment can be carried out, so that compromise treatment and safe use can be achieved.

The precautions for electrical safety inspection and maintenance are as follows, and the specific conditions of various types of safety inspection and maintenance can be appropriately used as a reference:

1. The person in charge of the construction must be familiar with the scope and location of the impact on the power outage maintenance line, explain it clearly to the construction personnel, and notify the affected unit by the dispatching room.

When the operation of the special fan is affected, the user must send a special person to the site to collapse, and the standby fan must be turned on and operated normally for 10 minutes before contacting the power outage for maintenance. After the overhaul is completed, the special fan will be turned on and run for 10 minutes before leaving the scene.

2. Before the power outage maintenance, the person in charge of the construction shall go to the substation with the power outage work ticket to go through the power outage procedures, and must see that the power distribution worker of the substation has indeed lost power, and will open and close the lock, and hang the power outage sign of "someone is working, not allowed to send power", and then get back the power outage card before leaving the substation.

For substations and distribution points without full-time power distribution workers on duty, the switch handle after the power failure must be locked or tied, the date of the power outage must be indicated, and the person in charge of the construction shall designate a special person to be responsible for taking care of it.

3. For the power supply of double circuit and annular circuit, maintenance personnel should go to each contact switch of the maintenance part to carry out reliable power failure work.

4. After the power failure of the maintenance part, the duty personnel of the substation shall first check the electricity with a qualified electric detector suitable for the power supply voltage, and carry out relative and interphase short-circuit discharge after confirming that the power failure part is not powered.

When discharging, it should be grounded first and then contact the line conductor, and after discharge, it should leave the line conductor first, and then leave the grounding. Discharge first to ground and then interphase discharge.

For the high-voltage part, the operator must wear insulated gloves, wear electrician's insulated boots or stand on the insulated table to carry out the above work.

5. After contacting the power outage and coming back, the maintenance personnel must carry out the electrical discharge inspection and discharge work in accordance with the provisions of Article 7, and pull the ground after the three-phase short circuit after the discharge, and then the maintenance work can be carried out.

6. No one who has gone through the power outage procedures shall not carry out any work on the power outage line.

7. Maintenance personnel are not allowed to arbitrarily change the original wiring to prevent short circuit, reversal and other accidents caused by wrong phase adjustment.

If the phase is reversed, the maintenance personnel must notify the power unit to pay attention to the reversal of the motor. Where two power trips are involved, they must be worked in parallel.

Hydropower installation project reservation and embedding is a stage that must be involved at the beginning of the project, a very important construction stage, and a stage to lay the foundation for follow-up work. If the implementation of the reserved pre-embedding stage is good, the follow-up work will be like a fish in water, and the progress will be smooth.

The most important work in the process of reserving and embedding is to be familiar with the construction drawings before construction, and the key work is to accurately locate the hydropower points during the construction process, cooperate with the civil engineering unit, meet the overall schedule requirements of the project, and avoid breach of contract. In the process of hydropower reserved and embedded construction, due to the low quality of the operators, poor sense of responsibility, insufficient management and supervision, and insufficient protection of finished products, there are often many common quality problems, which have a great impact on the cost and duration of our project in the later processes.

1. Electrical. 1. The bottom box of the shear wall is installed too deeply, and the visual quality is poor.

Add an inner support to adjust the distance of the bottom box out of the wall.

2. The bottom box of the air conditioning socket is installed too deeply, and there is chisel in the later stage.

First, the wire box is fixed and piping is carried out.

3. The socket conduit is not in the beam, and the bending process is increased with the masonry and burial in the later stage.

Directly embedded in the beam.

4. The elevation difference of the socket bottom box is out of tolerance, which does not meet the requirements of the national standard.

When the bottom box is installed, infrared rays are used for in-process control.

5. The protection of the finished product at the line nozzle is not in place, which leads to the blockage of the slag entering the nozzle.

Wrap with sealing glue.

6. The three layers of line pipe are overlapped, which is easy to lead to undense concrete pouring.

7. The welding lap length is not enough, and the welding quality is poor, which can easily lead to the grounding resistance not meeting the requirements.

2. Water supply and drainage.

1. The water-stopping section is not protected by the finished product and is easy to be destroyed.

Purchase water-stop section caps for plugging.

2. The air-conditioning casing is upside down or no slope or leakage.

3. The length of the embedded casing is not enough, which is easy to cause kicking in the beam and poor visual quality. Before installation, the casing should be brushed with two layers of anti-rust paint, and the outer wall of the casing should not be painted.

4. Compare and refer to the reserved plan of the casing and the pipeline system diagram to avoid the leakage of the casing.

After the completion of the reserved pre-embedding of the civil engineering pouring concrete, the reserved pre-embedded content is finally carried out a pre-concealment quality review to ensure that the reserved pre-embedded position is accurate, the number of embedded casing is complete, the position is correct, and the finished product protection measures are in place, and when the civil engineering pouring concrete, special personnel are arranged to be on duty, so as to avoid quality problems such as the disconnection of the line pipe connection and the deviation of the position of the casing.

1. If the developer's embedded water pipe leaks beyond the warranty period, who will be responsible.

If the water pipe embedded by the developer leaks after the warranty period, the property owner shall bear the responsibility for repair.

Regulations on the Quality Management of Construction Projects

Article 40 Under normal use conditions, the minimum warranty period of a construction project is:

A) infrastructure engineering, housing construction foundation engineering and main structure engineering, for the design documents specified in the reasonable service life of the project;

2) Roof waterproofing works, toilets with waterproof requirements, rooms and external walls for leakage prevention, for 5 years;

3) Heating and cooling system, for 2 heating periods and cooling periods;

4) Electrical pipelines, water supply and drainage pipelines, equipment installation and decoration projects, for 2 years.

The warranty period for other items shall be agreed between the employer and the contractor.

The warranty period of the construction project shall be calculated from the date of acceptance of the completion of the project.

Article 41 If a quality problem occurs within the scope and duration of the warranty of the construction project, the construction unit shall perform the warranty obligation and bear the liability for compensation for the losses caused.

Article 42 Where a construction project needs to continue to be used after exceeding the reasonable service life, the property owner shall entrust a survey and design unit with the corresponding qualification level to appraisal, and take measures such as reinforcement and maintenance according to the appraisal results to redefine the use period.

The construction party buried the damaged pipeline embedded pipe, and found that the damaged pipeline should be taken out and replaced after the warranty period, otherwise there will be leakage and other accidents.

After the dwelling is delivered by the developer, the developer shall bear the warranty liability under normal use, and the property management company shall bear the warranty liability. The specific period of the house warranty is: roof waterproofing for 3 years; Leakage of walls, kitchen and bathroom floors, basements, and pipes for 1 year; The walls and ceilings of the plastering house fell off for 1 year; Ground hollowing cracking, large-scale sand for 1 year; Doors and windows are cracked, and hardware is damaged for 1 year; Blocked pipes for 2 years; heating and cooling systems and equipment: 1 heating period or cooling period; 1 year of sanitary ware; 6 months for lamps and electrical switches; The warranty period for other parts and components shall be agreed between the real estate development enterprise and the user.

As can be seen from the above provisions, the situation you are talking about does not belong to the content of the mandatory provisions of the law, but belongs to the content agreed upon by you and the developer. Therefore, whether the developer is liable mainly depends on how the contract signed between you and the developer is agreed; If the developer is not liable, the situation is more complicated, it may be the community owners who are jointly responsible, or you may be responsible for yourself, of course, who is responsible is mainly determined by the nature of the water pipe.

The warranty period of the embedded pipeline project is 2 years.
