Description

Technical Field

[0001] The invention relates to a water supply pipeline system suitable for the maintenance of tap water supply pipelines. Background Art

[0002] There are "directional water supply system" and "tank water supply system", "directional water supply system" uses the water pressure in the tap water supply pipe to send a sufficient amount of water to the tap, and "tank water supply system" stores water in a tank installed on the roof of the building, etc., and sends water from the tank to the tap on each floor in the water supply method of the water supply system. In conventional high-rise buildings, the "tank water supply system" is generally adopted, but maintenance management such as regular inspection and cleaning of the tank is required. On the other hand, in the case of the "directional water supply system", inspection and cleaning of the tank are not required, and since the space for the tank is not required, there is an advantage that the site can be effectively used. In newly built high-rise buildings, the "direct water supply system" is often adopted. In conventional high-rise buildings, there are plans to switch the system from the "tank water supply system" to the "direct water supply system", and some of these plans have been implemented. The stored water is stored in the tank for half a day or more, dust in the air stagnates on the upper floor of the tank, and there is a concern that the water quality will deteriorate due to the influence of changes in ambient temperature or mixing of dust, etc., so regular maintenance is essential. In the "tank water supply system", for example, the owner is responsible for the quality of tap water in rental housing, and the corporate body is responsible for apartments, etc. The quality of tap water, but the water supply company may say that it is not responsible for the water quality of the pipes at the housing site. On the other hand, when the "direct water supply system" is newly adopted, the advantage is that no water storage tank is required, the water supply company guarantees the water quality in principle, and the burden on building property managers is reduced. Summary of the invention

[0003] In the case of the "direct water supply system", since a certain water pressure is required to supply water to the upper floors, water pipes with higher pressure resistance than conventional water pipes are used. In the case of the "direct water supply system", no water storage tank is set up, and the high pressure of the water pipe is used to supply water to the residents on the fourth to sixth floors of the building without using a booster pump. In order to supply water to residents on the upper floors, a booster pump is required. In addition, in buildings with a long construction history, it is also expected to deteriorate with the passage of time. Specifically, there is a concern that the water pipes are usually replaced due to rust of the connection parts, aging degradation of the adhesive or the pipe itself, or the like. In this case, the water company uses a material that inhibits the occurrence of rust, and the service life is about 30 to 40 years, so the long replacement cycle is an advantage. In addition, since it is prohibited to use coating materials to paint the inside or the like in the water supply pipes of public buildings, the water quality can be guaranteed.

[0004] Since water supply pipes are usually buried underground, when water supply pipes need to be replaced, the ground must be dug up first. In order to solve the problem that it takes time and effort to dig up water supply pipes because water supply pipes are usually buried 30 cm below the ground, when installing tiles, structures, etc. on the upper layer of urban water supply pipes, these materials need to be destroyed and removed before construction, and the time, effort and cost of construction become too high, and noise will be generated, causing trouble to residents. Especially when there is reinforced concrete on the ground, it is difficult to cut and remove the steel bars. In addition, when the water pipes are buried underground, the roots of adjacent trees will grow to lift the water pipes or penetrate into the pipes, which may cause leaks.

[0005] Therefore, the present invention is based on a viewpoint different from that of the related art, and an object of the present invention is to provide a water pipe system capable of renewing a tap water supply pipe at low cost and in a short time while suppressing the generation of noise, etc. as much as possible.

[0006] The urban water pipe equipment suitable for repairing urban tap water supply pipes comprises an urban tap water supply pipe arranged on the ground, and a reinforced concrete shelter having a U-shaped cross section formed by connecting side walls on both sides and a top wall, wherein the reinforced concrete shelter covers the urban tap water supply pipe in a state where the side walls on both sides are in contact with the ground. [Device effect]

[0007] According to the present invention, a water supply pipe system can be provided, which can replace the water supply pipe at low cost and in a short time while suppressing the generation of noise and the like as much as possible. [Brief Description of the Drawings]

[0008] Figure 1 is a perspective view showing a tap water supply pipe system according to the present invention; Figure 2 This is a cross-sectional view of the water supply pipe system according to the present embodiment in the direction of the axis. [Embodiment of the device]

[0009] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 is a perspective view of a water piping system according to an embodiment of the present invention, shown in an intermediate state of construction. Figure 2 1 is a view showing a water pipe system according to the present invention. This embodiment is cut in a direction perpendicular to the axis of the water pipe. In this specification, the term "ground" refers not only to a soil layer but also to a surface of a soil layer covered with a covering material such as a concrete layer or a tile, which is in contact with the covering material and the atmosphere.

[0010] In the figure, a concrete brick wall 13 is erected at the boundary between the housing land 11 and the public road 12, and a concrete layer 15 is formed on the housing land 11 and the soil layer 14 until it contacts the concrete brick wall 13, and tiles or the like can be installed on the concrete layer 15.

[0011] A tap water supply pipe 16 is provided on the upper surface of the concrete layer 15 near the concrete brick wall 13. Since the tap water supply pipe 16 of this embodiment is installed on the ground, it is preferably provided near the concrete brick wall to avoid becoming an obstacle for residents to pass through and to make effective use of the residential space.

[0012] The rear end of the tap water supply pipe 16 (at Figure 1 The front end of the tap water supply pipe 16 is connected to the water meter box 18 through a joint 17, and the pipe 19 extending to the outside through the water meter box 18 is connected to the indoor pipe (not shown in the figure).

[0013] The tap water supply pipe 16 disposed on the ground on the concrete layer 15 is covered and hidden by the reinforced concrete shelter 20 , and the tap water supply pipe 16 and the reinforced concrete shelter 20 constitute a tap water pipeline equipment.

[0014] The purpose of covering the water supply pipe 16 with the reinforced concrete shelter 20 is to: prevent the water supply pipe 16 from being deformed and broken due to unexpected external forces (such as the fall of heavy objects) because the water supply pipe 16 is installed on the ground, prevent the water supply pipe 16 from freezing due to exposure to low temperature environments, and prevent the water supply pipe 16 from aging due to direct sunlight. Therefore, the reinforced concrete shelter body 20 is made of concrete and steel bars. Concrete is a relatively strong material with excellent thermal insulation properties and does not allow light to pass through. The steel bars play a role in enhancing the strength and bearing capacity of concrete and reducing concrete cracking. For example, as the reinforced concrete shelter 20, a U-shaped groove made of concrete can be used inverted. Colors or patterns can be selected to be painted on the surface of the reinforced concrete shelter.

[0015] exist Figure 2 In the embodiment, a reinforced concrete shelter 20 is arranged near a concrete brick wall 13, and the reinforced concrete shelter has a U-shaped cross section in which a pair of side walls 21, 22 and a top wall 23 connecting the upper parts of the side walls 21 and 22 are continuously arranged. When the lower ends of the side walls 21, 22 are in contact with the concrete layer 15, a space 24 surrounded by reinforced concrete is formed. A tap water supply pipe 16 can be arranged in the space 24. When the metal clip 29 fixes the tap water supply pipe 16 wrapped with a heat insulating material 28 such as a foamed resin to the concrete layer 15 through a bolt 26, vibration and temperature change of the tap water supply pipe 16 can be prevented.

[0016] In this embodiment, the L-shaped metal iron sheet 25 is arranged on the surface of the concrete layer 15 and the outer surface of the side wall 22, and is locked by the concrete with bolts 26. Therefore, the reinforced concrete shelter 20 can be fixed on the concrete layer 15.

[0017] Next, the installation process of the tap water supply pipe system of the present invention will be described, and an embodiment will be described. Here, it is assumed that the existing tap water supply pipe 16' is connected to the water meter in the water meter box 18 and is replaced by a new tap water supply pipe 16. First, the soil layer 14 around the water meter box 18 is dug out to expose the existing tap water supply pipe 16', and the tap water supply pipe 16' is cut off.

[0018] Next, a new water supply pipe 16 is arranged along the concrete masonry wall 13 and connected to the water meter in the water meter box 18 through a joint 17 to replace the existing water supply pipe 16' cut, and the existing water supply pipe 16' is disconnected from the main pipe not shown and connected to the new water pipe 16. Mortar or the like is applied to the lower ends of the side walls 21, 22 and installed on the concrete layer 15 to cover the water pipe 16. The reinforced concrete shelter 20 is fixed to the concrete layer 15 by an L-shaped metal iron sheet 25, and when the pipe 19 is connected to the water storage tank (not shown in the figure), the pipe 19 is connected to the indoor pipe bypassing the water storage tank.

[0019] like Figure 1 As shown, when a plurality of reinforced concrete shelters 20 are connected and used to cover the tap water supply pipe 16, it is preferred to apply a caulking agent 27 or the like in the gaps between adjacent reinforced concrete shelters 20 to fill the gaps. In addition, the gaps between the tap water supply pipe 16 and the side wall 21 may also be filled with caulking agent, mortar or the like. After the tap water supply pipe 16 is installed, the periphery of the water meter box 18 is backfilled and the ground is leveled, thereby completing the construction.

[0020] According to the present embodiment, a new tap water supply pipe 16 is installed on the ground without removing the existing tap water supply pipe 16 from the soil layer 14. Therefore, even if the soil layer 14 is covered with a solid concrete layer 15, there is no need to destroy and remove the concrete layer 15. The installation work of the tap water supply pipe 16 is easy and the water supply stop time is short because the work is completed in a short time and does not cause any work noise trouble to the residents.

[0021] Since the newly installed tap water supply pipe 16 is protected by the reinforced concrete cover 20, it can be protected for a long time. In addition, when it is necessary to replace the tap water supply pipe 16, the tap water supply pipe 16 can be replaced after removing the L-shaped metal iron sheet 25 and removing the reinforced concrete cover 20, and then the removed reinforced concrete cover 20 can be installed again. Therefore, by reusing the equipment, waste materials are reduced and the cost required for replacement can be reduced.

[0022] In addition, by arranging the reinforced concrete shelter 20 near the concrete brick wall 13, it also has the effect of preventing the concrete brick wall 13 from collapsing when an earthquake occurs. Figure 2 As shown by the dotted lines in FIG. 1 , the top wall 23 of the concrete brick wall 20 and the blocking concrete brick wall 13 can be connected to each other by using an L-shaped metal iron sheet 25, which can more effectively prevent the concrete brick wall 13 from falling.
