Description

Multi-faceted concrete drainage pipe with skeletal reinforcement structure {MULTI-ANGLE CONCRETE DRAINAGE PIPE WITH FRAME REINFORCEMENT STRUCTURE}

The present invention relates to a concrete drain pipe buried underground, and more particularly, to a reinforcing structure of a concrete drain pipe for discharging rainwater while a plurality of joints are connected in a socket method.

A concrete drainage pipe buried in the ground to discharge rainwater generally has the shape of a circular pipe and is composed of an expanded pipe 102 having an enlarged inner and outer diameter and an inlet 103 inserted into the expanded pipe 102. Constructed by continuous joint connection of concrete pipe in socket method.

For such a concrete tube, a Hume tube of a round tube produced by centrifugal force or a VR tube produced by simultaneously applying vibration and voltage is used.

However, the above Hume tube or VR tube has a thin circular cross-section in which a thin iron wire (Ø4.0mm~6.0mm) is inserted due to the characteristics of the manufacturing method of the above-mentioned round tube, so there is a limit to the reinforcement method for increasing the rigidity. have. Therefore, it is common to reinforce insufficient strength by additionally pouring concrete around the perimeter of the drainage pipe at the site.

For example, Hume pipe or VR pipe of ready-made products can be used stably within 3~4m of fill height, so in order to use it as a lateral drainage pipe on a highway, pour the foundation concrete under the concrete pipe on-site or cut the outside of the concrete pipe with a square section. Concrete reinforcement is common. However, this reinforcement method entails cumbersome work processes such as formwork installation, reinforcing wire installation, concrete pouring and curing, removal of formwork, and watering until the reinforcement work is completed. This lengthens the construction period and greatly increases the construction cost. problems are arising. In addition, as described above, the reinforcement pouring of concrete for the outside of the Hume pipe or VR pipe makes it virtually impossible to form a hole to allow rainwater that has penetrated into the ground during the rainy season to flow.

Therefore, various reinforcement methods have been proposed to solve the above-mentioned problems of concrete pipes composed of Hume pipes or VR pipes.

For example, Korean Patent Laid-Open Publication No. 1995-0001165 discloses, as shown in FIG. 1 , a reinforcing treatment layer by attaching a glass fiber 3 woven to the outer surface of a concrete pipe 1 with a polymer adhesive 4 . (30) is formed.

In addition, in Patent Registration No. 10-1779260, as shown in FIG. 2, a general primary concrete layer 10 in which a wire mesh 30 is inserted is formed, and a secondary containing reinforcing fibers inside thereof is formed. A concrete pipe is manufactured in such a way that the concrete layer 20 is formed.

The concrete pipe of these prior art improves the rigidity of the concrete pipe itself by attaching or containing a fiber-reinforced material with high tensile rigidity such as glass fiber.

However, the reinforcing process itself is not simple, such as requiring meticulous surface treatment for the adhered surface of the concrete pipe to attach the sheet-like fiber-reinforced material, and the epoxy resin and primer for its adhesion are weak against moisture. In addition, even when a reinforcing structure is obtained by mixing reinforcing fibers with concrete mortar as in Registration No. 10-1779260, quality control is difficult because it is not easy to check the dispersion state along with the problem of slump reduction. There is a problem in that it is not easy to secure high rigidity and reliability.

In addition, since the outer diameter of the expansion pipe 102 is larger than the outer diameter of the body or the inlet 103, the concrete pipe of the prior art is not easy to load during transportation, and the concrete pipe is placed on the floor for joint connection work. There is a problem in construction that it is necessary to always use a pedestal to maintain the equilibrium state of the concrete pipe, and there is a problem that a large construction cost is required because tension equipment such as a crane or white walnut must be used even when connecting joints.

US 10-1995-0001165 A US 10-1779260 B1

The present invention is intended to solve the problems of the prior art, and reinforces the concrete drainage pipe by using reinforcing bars of a general material and dispersing stress throughout the body through the structure of the cross-section, and excavated earth floor for joint connection work An object of the present invention is to provide a multi-faceted concrete drainage pipe having a skeletal reinforcement structure that not only makes it unnecessary to use a separate supporting member to support the concrete drainage pipe placed on the surface, but can also increase the bearing capacity of the excavated floor surface.

In addition, the present invention can be quickly drained of rainwater to increase drainage efficiency, improve durability, minimize the use of lifting equipment during construction, and multi-faceted concrete having a skeletal reinforcement structure that can promote efficiency and safety of construction We want to provide a drain pipe.

In addition, an inlet hole communicating with the internal space may be formed on the outer surface of the main body, or an inclined guide drainage channel may be further configured here to introduce underground rainwater during the rainy season so that it can be drained quickly and efficiently. The guide drainage can be configured by forming a separate guide rib on the outer surface of the main body or using a horizontal skeleton.

In addition, by distributing the rapid protrusions on the inner surface of the lower half-section of the main body to increase the flow rate, foreign substances such as earth and sand do not accumulate on the inner surface, thereby promoting ease of maintenance.

The concrete drainage pipe of the present invention does not use a different type of reinforcing material and has a reinforced concrete structure identical to that of a conventional concrete pipe. It becomes cheaper and has the effect of shortening the construction period by eliminating the need for additional reinforcement work in the field.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the description of the present invention, in the case of obscuring or obscuring the technical idea of the present invention due to the detailed description of the known configuration, the description of the above known configuration will be omitted.

3 is a view (perspective view) of the concrete drain pipe 100 according to an embodiment of the present invention, and FIG. 4 is a cross-section at each part of A-A, B-B and C-C of FIG. 3 .

The concrete drain pipe 100 of the present invention is buried in the ground to discharge rainwater, and is configured to form one conduit by connecting a plurality of joints in a socket structure bonding method, similar to a conventional Hume pipe or VR pipe.

That is, centering on the body portion 101 having a water-through inner diameter, an enlarged pipe portion 102 having an inner diameter greater than the water-passing inner diameter is formed on one side, and an inlet portion 103 inserted into the inner side of the water-passing tube 102 is formed on the other side. is formed

However, the concrete drain pipe 100 of the present invention, unlike a conventional Hume pipe or VR pipe having the same circular appearance as the inside, includes an expansion pipe 102 and an inlet 103 at the lower part, and has one flat surface. An expanded bottom surface portion 110 is formed.

The expanded bottom part 110 increases the contact area of the concrete drain pipe 100 with respect to the excavated floor while widely distributing the load applied through the concrete drain 100 to suppress the occurrence of subsidence, and also to the excavated ground. By maintaining a horizontal state in the concrete drain pipe 100 placed on the surface, the workability is improved.

That is, as described above, since the respective outer diameters of the expansion tube 102 and the inlet portion 103 are different from each other, a supporting member is installed between the excavation floor surface and the concrete drain pipe 100 to maintain a horizontal state. Unlike the pipe, since the expansion pipe 102 and the inlet part 103 at the part in contact with the excavated bottom surface maintain the same flat surface through the expanded bottom part 110, the above-mentioned supporting member is used as a concrete drain pipe (100). It does not require the work itself to install according to the location where it is placed.

In this case, two tension rings 151 may be further installed on the side of the extended bottom surface portion 110 located in the middle of the main body portion 101 .

The tension ring 151 enables joint connection work using only the lever block 200 without using heavy equipment such as cranes or backhoes when connecting the front and rear concrete drain pipes 100 by joint. Improves constructability and worker safety.

5 is a cross-sectional view illustrating a work process of jointly connecting the concrete drain pipe 100 using the lever block 200 . When the hook 210 of the lever block 200 is hung on each tension ring 151 of the concrete drain pipe 100 located in the front and rear and tightened between them, since each concrete drain pipe 100 is located on the same horizontal line, The inlet part 103 of the concrete drain pipe 100 located at the rear is easily inserted into the expansion pipe 102 of the concrete drain pipe 100 located in the front without a separate adjustment operation. Therefore, there is little room for damage to the ends of the concrete drain pipes 100 colliding with each other during the above joint connection work.

This tension ring 151 may be utilized as a lifting ring for lifting during the transport process.

The lower half of the concrete drain pipe 100 including the side surface of the expanded bottom part 110 is configured to be perpendicular to the flat surface of the expanded bottom part 110, and the upper half is the arc cross-section shown in FIG. 6 to the trapezoid shown in FIG. It has a multi-sectional structure such as

Accordingly, when backfilling after the installation of the concrete drain pipe 100 is completed, there is little room for voids to occur in the lower part of the side of the concrete drain pipe 100 .

In addition, the present invention forms a reinforcement skeleton 120 on the outer surface of the main body 101 of the concrete drain pipe 100 to have sufficient rigidity in the concrete drain pipe 100 itself, so that even if the cover has a depth of 5 m or more, a separate reinforcement work in the field make it unnecessary to do

As shown in FIG. 3, the reinforcing skeleton 120 forms a horizontal skeleton 121 in the longitudinal direction on the upper part, and forms vertical skeletons 122 extending to both sides around it at regular intervals. It can be configured, but in addition, as shown in FIGS. 6 and 7, it can also be configured with the reinforcing skeleton 120 of various shapes, such as the oblique skeleton 123 and the cross skeleton 124, and a mixture of these can also be used. .

In addition, depending on the embodiment, the reinforcing skeleton 120 may be configured to protrude or may be configured in a shape in which the reinforcing skeleton 120 is embedded so that it does not appear to the outside. Of course, as will be described later, the horizontal skeleton 121 may be formed at an intermediate height of the main body 101 .

In the case of the structure in which the reinforcing skeleton 120 protrudes as in the former case, the reinforcing skeleton 120 suppresses the sliding activity of the concrete drain pipe 100 in the state in which the backfilling is completed, thereby preventing the occurrence of a gap in the joint connection portion. effect can be expected.

The reinforcing frame 120 may be a concrete structure in which a steel material is embedded, for example, a reinforced concrete structure in which a deformed reinforcing bar 132 is embedded. Therefore, while a conventional welded wire mesh 131 is embedded in the inside of the main body 101, such as a Hume tube or a VR tube, it has a reinforcing structure by the deformed reinforcing bars 132 arranged at regular intervals outside thereof.

8 and 9 each show a concrete drain pipe 100 according to another embodiment of the present invention.

As shown in FIGS. 8 and 9 , an inlet hole 141 communicating with the internal space may be further provided on the outer surface of the main body 101 of the concrete drain pipe 100 .

The inlet hole 141 introduces rainwater soaked into the ground during the rainy season into the concrete drain pipe 100 to allow rapid drainage, and reduces the load applied to the concrete drain pipe 100 by lowering the raised groundwater level. It prevents the joint connection part of the drain pipe 100 from being bent or damaged.

However, the inlet hole 141 inevitably accompanies a cross-sectional defect with respect to the concrete drain pipe 100 , and the formation of too many inlet holes 141 lowers the cross-sectional rigidity of the main body 101 . Therefore, as shown in FIG. 8, the inlet hole 141 is positioned on the upper half of the body portion 101 through which the inflow of underground rainwater is efficiently made, and the cross-sectional defect is located in the lower half of the cross-section that receives a lot of leaflet bearing force and tensile force. It is desirable to avoid this from occurring.

9 is a view showing the concrete drain pipe 100 of another embodiment in relation to the configuration of the inlet hole 141 above. According to this, the induction drain 142 is formed on the outer surface of the main body 101, and the rainwater induced by the induction drain 142 is concentrated into any one of the inlet holes 141 communicating therewith, so that the inflow efficiency of rainwater. to minimize the number of inlet holes 141 to be formed on the outer surface of the main body 101 .

For example, as shown in (a) of FIG. 9, a guide rib 143 communicating with the inlet hole 141 is separately configured to form a guide drain 142, or as shown in FIG. 9 (b) By allowing the reinforcing skeleton 120 itself to communicate with the inlet hole 141 , it can function as the induction drain 142 .

In the former embodiment in which the guide ribs 143 are separately configured, one of the reinforcing skeletons 120 formed in the main body 101 for reinforcing the concrete drain pipe 100, the vertical skeletons 122 in the vertical direction are spaced at regular intervals. It can be easily applied when it is formed to protrude. A ∨-shape or ∧-shaped induction rib 143 is formed between the adjacent vertical skeletons 122, and an inlet hole 141 communicating with it is located at the lowermost position of the induction rib 143. . Fig. 9 (a) is an example of a case in which the induction rib 143 is formed in a ∨ shape and the inlet hole 141 is formed at the lowermost vertex.

These guide ribs 143 can also expect the effect of cross-section reinforcement to compensate for the cross-sectional defect generated by the inlet hole (141).

In addition, in the latter embodiment using the reinforcing skeleton 120, a horizontal skeleton 121 in the horizontal direction is formed at an intermediate height of the main body 101 as one of the reinforcing skeletons 120 for reinforcing the concrete drain pipe 100. is applicable to At this time, it is preferable to smoothly perform the function of the induction drainage channel 142 by configuring the upper surface of the horizontal skeleton 121 to be inclined downward toward the inlet hole 141 .

For example, as shown in (b) of FIG. 9 , the horizontal skeleton 121 may be inclined downward to both sides in the middle portion and the inlet holes 141 may be formed at both ends, respectively, on the contrary, both sides of the horizontal skeleton 121 . It may be inclined downward to the middle part and the inlet hole 141 may be configured in the middle part.

FIG. 10 illustrates an action relationship for introducing rainwater into the concrete drain pipe 100 using the induced drain pipe 142 described above.

On the other hand, the slow drainage flow inside the concrete drainage pipe 100 acts as a factor in which foreign substances such as earth and sand are deposited on the inner surface. Therefore, the concrete drain pipe 100 of the present invention may be further provided with a rapid protrusion 171 to prevent this.

11 shows the concrete drain pipe 100 of the present invention provided with the rapid protrusion 171, and FIG. 12 shows an embodiment regarding the arrangement of the rapid protrusion 171. As shown in FIG.

The rapid protrusion 171 forms a rapid by increasing the flow rate while changing the flow direction of water back and forth on the surface when water flows. Therefore, the shoal projections 171 are dispersedly disposed on the lower inner surface of the side surface of the main body 101, which is a position where foreign substances such as earth and sand are deposited. The rapids generated by this prevent the sedimentation of foreign substances such as earth and sand introduced into the concrete drain pipe 100 and discharge to the outside together with rainwater, thereby minimizing the amount of maintenance work such as internal cleaning.

When the arrangement of the rapid projections 171 is such that each row of the rapid projections 171 continuously arranged in the longitudinal direction has a twisted shape in any one direction, a vortex is generated in the flow on the surface. Settling can be prevented more effectively.

The concrete drain pipe 100 of the present invention may further include an installation hole 152 capable of fixing the joint reinforcement 160 to the side of the expanded bottom part 110 where both ends of the main body 101 are located. .

13 shows an example in which the reinforcing jointing hardware 160 is installed in the jointly connected concrete drain pipe 100 .

The reinforcing jointing iron 160 strongly maintains the connection state at the joint connection between the concrete drain pipes 100 to prevent the conduit from being deformed or damaged, thereby improving durability.

For example, in the conduit constructed by continuously connecting the concrete drain pipe 100 of the present invention, the activity in the longitudinal direction of the concrete drain pipe 100 is prevented by the reinforcing skeleton 120 protruding from the outer surface of the main body 101, and in soft ground The movement of up and down, which may be caused by the lack of support, is prevented by the extension bottom surface part 110 and the socket structure joining method by the expansion pipe part 102 and the inlet part 103, respectively. At this time, the reinforcing jointing iron 160 acts in both the longitudinal direction and the vertical direction by securing the integrity of the continuous concrete drain pipe 100, and the action of preventing activity in the longitudinal direction and the vertical direction by the above-described components is long-term. By allowing it to be maintained continuously, the durability of the conduit is improved.

In the above, the present invention has been described in detail with reference to specific embodiments, but since the embodiments are merely examples for easy understanding of the present invention, those of ordinary skill in the art should be within the scope of the technical spirit of the present invention. It is obvious that it can be implemented with various modifications within. Accordingly, such modifications will be said to be within the scope of the present invention as described in the claims.
