Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a prefabricated structure for a water pipe,

The present invention relates to a prefabricated structure for a water supply valve chamber, and more particularly, to a prefabricated structure for a water supply valve chamber, which is waterproof and which is required to have waterproof performance, is constructed by using a concrete block using a concrete block, The present invention relates to a prefabricated structure for a water pipe valve chamber.

Generally, a water pipe buried in the ground from a water source to a supply point is formed by a pipe having a larger diameter as the water source is closer to the water source, and the pipe is gradually installed with a smaller diameter.

At this time, the water pipe is not directly connected to the supply point, but the valve is installed in the middle due to factors such as inspection, management, and branching. In order to maintain the valve, the valve is located in the structure called the valve chamber.

Figs. 1 and 2 show a conventional example of the construction of the valve chamber.

Specifically, in the conventional valve chamber construction, the bottom floor of the valve chamber is poured into the excavated soil, the bottom foundation steel is assembled and assembled, and then the floor concrete is poured. Then, the water supply pipe and the valve are assembled and installed as shown in FIG. After installing the outer wall and inner wall formwork, scaffolding, tiller, etc., concrete is poured, cured, and then the inner formwork is dismantled. After the exterior and interior waterproofing works, the ladder, footplate, valve And installing an accessory such as a kite board.

As a result of this construction, it takes a great deal of time and cost to construct the valve chamber.

In order to solve this problem, there have been disclosed a number of techniques for making the valve chamber wall into an integral structure of synthetic resin, but these structures have been found to have a longer life than the conventional concrete installation type valve chamber. Recently, The integrated resin wall structure is being abandoned.

As another technique, a "block-assembled valve chamber manhole" (Korean Patent Registration No. 10-1318655, Patent Document 1) has been disclosed.

Patent Document 1 discloses a structure in which an intake block or a masonry block having the same curvature is radially disposed, a reinforcing rib is formed in an intake block, and an intake block and a fitting groove are formed and connected to each other.

The entrance block of Patent Document 1 is formed of a synthetic resin material since the reinforcing rib is formed therein.

However, Patent Document 1 also uses a block made of a synthetic resin material, and the synthetic resin material is not environmentally friendly. In the state where the valve chamber is installed in the ground, it can not firmly resist against the earth pressure applied from the outside, So that water leaks into the inside of the valve chamber, thereby contaminating the internal environment of the valve chamber.

Particularly, a valve chamber to be buried in the ground is generally maintained for at least several decades. In the case of a plastic material, there is a problem that it must be made of a very expensive member to satisfy such a condition.

The bottom 10, which is a component of the present invention, may be constructed of cast-in-place concrete as in a conventional valve seal construction.

At this time, preferably, as shown in FIG. 5, a "U" shaped lower fitting groove 11 having upwardly bent both ends upwardly is formed on the cast-in-place concrete as shown in FIG. 5, The lower blocks 22 constituting the upper and lower blocks 20 may be inserted and installed.

Specifically, the bottom portion 10 can be achieved by installing a steel plate as shown on the floor of the cast-in-place concrete, and installing a steel plate having a shape of "∪" along the periphery of the steel plate.

This makes it possible to prevent moisture infiltration from occurring between the bottom part of the wall part 20 and the bottom part 10 without any additional waterproof construction.

The wall 20 as a component of the present invention is constructed such that a valve chamber 21 on which a valve 2 is installed is formed above the bottom 10, A plurality of blocks 22 made of a concrete material are continuously connected to the left and right along the circumference of the upper surface of the main body 10 and are laminated successively on the upper side.

In addition, the wall portion 20 is formed with an opening 23 for inserting the water pipe 2 into the valve chamber 21 as shown in Fig.

At this time, the detailed configuration of the blocks 22 is shown in detail in FIGS. 3 and 10.

First, the blocks 22 are configured to engage and engage with the pair of engaging projections 22b and the engaging grooves 22a, as shown in FIG. 1, to be engaged horizontally with each other.

10 shows a block 22 in which coupling projections 22b and coupling grooves 22a are formed in directions opposite to each other in accordance with the position of the block 22 and coupling grooves 22b and coupling grooves 22a, The block 22 is shown in Fig.

10 shows an example in which the blocks 22 are connected in a line along the wall portion 20. In the case where the blocks 22 are installed in multiple rows, a coupling groove 22a is formed on two surfaces of four sides of the block 22 And the engaging protrusions 22b may be formed on the remaining two surfaces.

6, the width direction of the block 22 is wide and the width direction of the inside of the block 22 is narrow. As shown in FIG. 6, The block 22 adjacent to the coupling groove 22a of the block 22 as a reference when the blocks 22 are connected to each other is assembled such that the coupling projections 22b are fitted in the vertical direction, It means that the structure is such that it can not be separated by the structure.

3, 6 and 10, the outer ends of the engaging projections 22b are engaged with the engaging grooves 22b of the engaging grooves 22b, 22a, and the vertical sealing member 22i is vertically fitted to the spaced space so that the airtightness can be improved.

The vertical sealing member 22i may be made of a resilient packing material such as rubber corresponding to the shape of the spaced space or larger than the space, so that the vertical sealing member 22i can be dry-fitted to the upper sealing member 22i.

The length of the vertical sealing member 22i may be a length extending from the upper end of the entire wall portion 20 to the lower end than the length corresponding to the height of the unit block 22.

In addition, after the basic assembly of the wall part 20 is completed, the waterproofing performance may be achieved by a wet type method of injecting a waterproofing solution into the space of the connection clearance between the upper blocks 22 and curing.

As shown in FIGS. 3 and 10, each of the blocks 22 has a vertical connection hole 22c vertically penetrating the vertical connection member 22d Are connected to each other by being installed through vertical connection holes 22c of upper and lower adjacent blocks 22.

In this case, it is preferable that the vertical connecting member 22d is formed of a steel material. As shown in the figure, the vertical connecting hole 22c and the vertical connecting member 22d are formed in a unit polygonal shape, So as to prevent the phenomenon of being assembled while being twisted.

When each block 22 is coupled in the horizontal direction, only the fitting engagement between the engaging groove 22a and the engaging projection 22b insufficiently holds the external earth pressure in the state where the wall portion 20 is buried in the ground In order to prevent the bearing blocks 22a and 22b from being damaged due to wear and tear on the concrete block 22b, the blocks 22 may be horizontally connected to each other in the horizontal direction as shown in the horizontal direction, A horizontal connection reinforcing member 22f having a plurality of holes 22e formed therein and passing through the plurality of horizontal connection holes 22e is installed through the horizontal connection holes 22e of the adjacent blocks 22, .

Particularly, the horizontal connection reinforcing member 22f is formed such that a thread is formed at the end thereof and is projected outside the horizontal connection hole 22e of the block 22 at both side ends constituting one surface of the wall portion 20, A tension member is tightly coupled to the threaded portion formed on the opposite side of the torsion bar so that the adjacent blocks 22 in the horizontal direction can be firmly tightly coupled.

10, the blocks 22 forming the wall surface portion of the wall portion 20 have such a structure that the horizontal connection hole 22e completely penetrates both ends only in the longitudinal direction, and the wall portion 20, The blocks 22 corresponding to the corners may be formed in such a structure that the horizontal connection holes 22e pass through all four surfaces in the horizontal and vertical directions and then be tensioned and bound through the horizontal connection reinforcing member 22f.

When such a structure is adopted, the height of the horizontal connection holes 22e of the blocks 22 corresponding to the respective surfaces may be different from each other.

In addition, the block 22 has a sealing material mounting groove 22g having a semicircular cross-sectional shape on the upper and lower surfaces, the upper surface and the lower surface, as shown in Figs. 3 and 10, And the horizontal sealing material 22h having the circular sectional shape shown in the drawing is fitted in the sealing material installation groove 22g of the adjacent blocks 22 to prevent water infiltration through the interface between the upper and lower adjacent blocks 22 can do.

At this time, the horizontal sealing material 22h is formed to correspond to the length of one side of the wall 20 rather than to the length of the unit block 22.

The horizontal sealing material 22h may also be applied in a dry or wet manner like the vertical sealing material 22i.

In addition, the position of the sealing member mounting groove 22g in a plane is formed on both sides of the coupling groove 22a as a reference, so that the sealing is doubly formed on the inner side and the outer side of the block 22, .

As shown in FIGS. 3 and 4, the ceiling portion 30, which is a component of the present invention, is installed on the wall portion 20 and has a check port 31 communicating with the valve chamber 21 at one side thereof have.

The shape of the ceiling portion 30 may be a slab shape as shown in FIG. 3, or a curved shape like a dome according to circumstances.

As shown in FIGS. 3 and 8, in order to prevent water infiltration or the like between the ceiling portion 30 and the upper block 22 of the wall portion 20 by a dry method, the inspection port 31 is formed at one side The upper roof member 32 is fixed to the upper roof member 32 along the lower circumference of the upper roof member 32. The upper roof member 32 is fixed to the upper roof member 32 by the upper roof member 32, And a wall connecting member 33 that is bent downward at the inner and outer ends so that a block insertion groove 33a to be coupled is formed.

The wall connecting member 33 may be manufactured by welding and fixing a plurality of angles to an iron plate.

Since the downwardly bent portion of the wall connecting member 33 surrounds the outer circumferential surface and the inner circumferential surface of the upper block 22, it is possible to prevent infiltration of external moisture. In particular, the upper roof member 32 is made of a material such as an iron plate It is possible to easily combine them by welding or the like while being composed of the same material.

As shown in FIG. 3, the cover 40, which is a component of the present invention, has a through hole 41 through which the water pipe 2 passes, and is configured to close the opening 23 have.

The cover 40 shown in Fig. 3 has two frames fitted in the inner and outer corners of the block 22 contacting the openings 23, respectively, and the cover member 42 is fixed to each frame 43 .

Specifically, the frame 43 includes a side contact portion 43a which is brought into close contact with the side wall surface of the block 22 contacting the opening portion 23 so as to be in close contact with the inner peripheral surface at the inner periphery and the outer peripheral edge of the opening portion 23, And an outer circumferential surface close contact portion 43b that is bent perpendicularly to the side close contact portion 43a while being connected to the side close contact portion 43a and is in tight contact with the outer circumferential surface of the block 22 contacting the opening portion 23. In the center, (2) A clearance through hole 44 larger than the outer diameter is formed.

That is, it can be easily manufactured by welding multiple angles orthogonally to each other.

The cover member 42 has a through hole 41 corresponding to the outer diameter of the water pipe 2 at the center thereof and is connected to the water pipe 2 at one side thereof, And is fixed to the frame 43 by welding or the like.

This configuration prevents a clearance between the block 22 and the cover 40 that surround the opening 23 through the frame 43 and the cover member 42 is fitted tightly with the water pipe 2 So that airtightness can be maintained.

At this time, a packing may be optionally provided in the through hole 41, or a silicone waterproof liquid or the like may be applied to prevent a gap with the outer circumferential surface of the water pipe 1.

An example in which such a cover 40 is installed is shown in Figs. 8 and 9. Fig.

As can be seen from the drawing, it can be seen that a pair of the frame 43 and the cover member 42 are provided inside and outside the openings 23, respectively.

This prevents double infiltration of moisture through the opening 23 through the double installation structure.

In addition, it is possible to inject the quick-setting mortar into the gap using the dual installation structure to prevent the flow of the surrounding blocks 22 and to maximize the waterproof performance.

More specifically, as shown in FIG. 9, one of the two cover members 42 connected to the two frames 43 is provided with a mortar injection hole 45 communicating with the clearance through hole 44, The non-shrinkage ultra low speed mortar 46 can be injected into the space between the two cover members 42 and the outer circumferential surface of the water pipe 1 through the holes 45 to be finished.

In this case, it is possible to prevent the flow of the water pipe (1) and to prevent the sagging of the water pipe (1).

The construction of the prefabricated structure for a water pipe valve of the present invention constructed as described above will be briefly described below.

First, the bottom concrete is poured into the excavated soil, then an iron plate is installed as shown on the bottom surface, and a bottom portion 10 is installed by installing a steel material having a "∪" shape along the periphery of the steel plate.

Then, a plurality of blocks 22 are prepared, the first wall section 20 is constructed in such a manner that the coupling grooves 22a and the coupling protrusions 22b are fitted to the left and right, Are stacked and multi-stage construction is carried out.

During the construction of the upper and lower blocks 22, the horizontal sealing material 22h is fitted in the sealing material mounting groove 22g.

After the blocks 22 are installed, the vertical connection member 22d is passed through the vertical connection holes 22c of the upper and lower straight lines, the horizontal connection holes 22e forming the straight line are passed through the horizontal connection reinforcing member 22f, The vertical sealing member 22i is fitted in the spacing space between the engaging projection 22b and the engaging groove 22a.

By this construction, the sealing work of horizontal and vertical connection parts between the blocks 22 constituting the wall part 20 can be easily completed.

The frame 43 is provided on the inner side and the outer side of the respective openings 23 and then the water pipe 1 is passed through the clearance through holes 44 and the openings 23 of the frame 43, ), Then install valve (2).

The water pipe 1 is inserted into the through hole 41 of the cover member 42 before passing through the water pipe 1 and then the valve 2 is assembled.

Then, the cover member 42 is fixed to the frame 43, and the cover 40 is installed and the installation of the water pipe 1 is completed by injecting the quick-speed mortar 46 into the mortar injection hole 45.

Then, the ceiling portion 30 is installed on the upper part of the wall portion 20, and the construction is completed by filling the soil around the wall portion 20.
