First, attach importance to the contract. Since many problems are in the contract, it is recommended that both sides of the contract must clarify the contents of the contract before signing the contract. Each article will not fall flat. The decoration company is responsible for telling customers what each contract term means. Consumers should not sign their names easily, regardless of the size of the contract, before they fully understand the contract. If the annex to the contract (drawings, quotation, material procurement plan, construction plan) is not completely prepared, do not sign it.
Second, the green environmental protection requirements in the design program. The decoration association of the province often encounters consumers who are required to inspect the indoor air environment after home improvement. Before that, they did not have this requirement. In fact, even if the content of harmful gases is exceeded at this time, it is difficult to find a solution. Therefore, we must "prevention-based, testing supplemented." Put your own requirements for environmental protection in the contract and put it in the design plan.
Third, strictly perform the contract until the end of the contract. Even if there are some changes to the contract itself, it must be discussed with the other party to the contract. He himself should also ask the other party to strictly perform the contract. This is a responsible attitude towards his own legal rights and the other party’s legal rights. The problem is also guaranteed for himself.
It should be reminded that when the owner signs a contract with the construction unit, it is necessary to sign the liability for breach of contract and related liability. It is best to determine the specific amount of liquidated damages per day. If it is based on the ratio of the total project price, it is best to measure the amount of the specific amount equivalent to each day. If the amount of liquidated damages is too small, it may not achieve the effect of restraint.
In addition, different construction projects have different warranty periods. According to the regulations, the warranty period for bathroom walls, floors, and waterproof requirements and anti-leakage projects shall not be less than 5 years. The warranty period for electrical pipelines, water supply and drainage pipelines, equipment installation and renovation projects shall not be less than 2 years. The warranty period for wooden floors and cabinets must not be less than 1 year. Other construction projects should be carried out according to the warranty period agreed by both parties.
During the warranty period, the maintenance issues after the quality problems occurred in the project are also the focus of the home improvement complaints. Home improvement companies think that as long as they are repaired to ensure normal use of it, and some owners believe that they should compensate for economic losses. In this regard, it should be stipulated in the home-installed contract so that when problems arise, they can follow the regulations.

The structure of the core barrel is generally divided into single - acting double core tube and most of the fishing apparatus. The double tube section consists of an outer tube assembly and an inner tube assembly. The outer pipe assembly includes; The main structure and working principle of the cartridge stopper, cartridge chamber, stable joint outer pipe, diamond reamer and diamond bit are as follows:
(1) Spear structure is composed of spear head and recovery spring. When coring, the fishing device is lowered to the upper part of the inner tube assembly in the drill pipe, and the fishing hook grasps the fishing spear, lifts the fishing device up, picks up the recycling card barrel, and inwardly compressing the cartridge card, so that the inner tube assembly and the outer tube are separated, so that the inner tube assembly is lifted up.
(2) The clip structure is mainly composed of the clip frame, clip, spring and other components. Its function is that when the inner tube sits on the outer tube, the clip expands with the help of the elastic force of the expansion spring and sticks to the inner wall of the clip chamber, so that the drilling tool can achieve positioning.
(3) Buffer structure by spring, locking mother, split pin composition. Protecting the inner tube when pulling the core.
(4) Single action structure is realized by two pairs of thrust bearings.
(5) Adjust the length of the inner pipe assembly and the outer pipe assembly of the structure, and fine-tune the lower shaft and the locking mother to achieve the gap required by the end of the spring seat and the step inside the drill bit.
(6) The fishing structure, also known as the fishing device, is mainly composed of fishing hook, hammer and safety rope. The fishing hook is used to hold the spearhead while fishing the inner pipe, and the weight is used to speed up the fishing device's descent to save fishing time. The safety rope is a thin rope. When the inner pipe is stuck for some reason and cannot be lifted, the safety rope can be forcefully lifted and then the drill can be lifted.
