Description

Watercourse made from Polymer concrete

The present invention relates to a water drainage channel which is basically applied to civil engineering, agricultural engineering, complex construction and forestry projects, and more particularly, a polymer having high strength and light weight, resistance to freezing and thawing and excellent corrosion resistance to various chemical substances. Unsaturated polyester) relates to a polymer concrete distribution channel for producing a channel using concrete.

The demand for water resources is increasing due to the development of industry and the improvement of quality of life, but it is not easy to accommodate this with existing rainfall, and the development of new reservoirs or dams has been pushed by environmental protection theory.

As a way to cope with this, it is important to save water that has been developed and improve the efficiency of water resource use. Specifically, it is earthwork drainage that digs water into a trench like a ditch, on-site concrete pouring drainage for placing concrete structures in the ditch, precast concrete drainage drainage factory made in advance, drainage drainage made of waste plastic, etc. Can be mentioned.

However, in the earthwork drainage, a huge amount of water leaks causes a great economic loss, and in the case of poor water quality, a huge amount of water leaks disrupts the water quality and quantity of the groundwater, disrupts the habitat environment of the underground organisms, and damages the natural environment. Also, it was difficult to maintain the waterway section due to frequent slope collapse in the rainy season, and there was a problem that costly maintenance was required such as frequent repair and removal of water plants breeding in the waterway.

In addition, in the field concrete pouring type drainage, it is generally difficult to control the quality during site construction because of its small size, and the quality and strength is severely deteriorated due to unfavorable construction conditions. When combined with, the oxidation process is accelerated, the concrete is cracked due to volume expansion due to the oxidation of the reinforcing bar, and since it is exposed to water inside and outside the structure, the service life is shortened. There was a problem that the maintenance cost is sharply increased, and also a large amount of concrete waste is generated when discarding the use, there is a problem that the environmental damage is intensified because the recycling of the waste is practically impossible.

Also, precast concrete drainage is largely suitable for small waterways (mainly low width of 1m or less) because of its large weight and poor installation and movement. In the long term due to the neutralization, there were problems such as a decrease in strength and durability and a problem of cracking in the concrete structure due to the deeper oxidation of the reinforced rebar due to less water tightness.

In addition, the waste plastic drainage has a problem that the waterway itself is destroyed due to buoyancy caused by water penetrating under the waterway due to its low weight, and there is a risk of premature damage due to deterioration of plastic due to ultraviolet rays when exposed to sunlight for a long time. Leakage occurred due to deterioration of the reliability of the joints connecting the waterways, deformation was caused by the side wall earth pressure due to the low strength, and there were various problems of deformation due to fire and loss of waterway function due to weak heat.

Therefore, the present invention was created to solve the above problems, the purpose is to use a polymer (unsaturated polyester) concrete having high strength and light weight, excellent resistance to freeze-thawing and corrosion resistance to various chemicals, etc. In addition, it is possible to produce an open water channel for water drainage, and to secure the joints between waterway units to prevent leakage, to prevent buoyancy from acting on the waterway itself against the underground water level, and to prevent abnormal deformation of the waterway by sidewall earth pressure. In addition, the present invention provides a polymer concrete drainage channel for easily assembling the vertical wall and the bottom of the channel unit in the field.

In order to achieve the above object, the present invention provides a vertical wall 11 having a triangular support rib 11b, a bottom portion 12, a buoyancy preventing rib 19 extending from the bottom portion 12, and a number thereof. First joint means 14 for connecting and installing the respective channel units 10 opposed to each other at both edges of the corners facing the straight wall 11 and the bottom 12, and the outer upper portion of the vertical wall 11 Polymer concrete with a second joint means 15 for connection between the channel unit 10 opposed to both edges, and a water-repellent material 13 made of rubber material for watertightness in at least one end surface of the channel unit 10. In the water drainage, polymer concrete drainage, characterized in that the support ribs (11b) and the buoyancy prevention ribs (19) of the vertical wall (11) is assembled in the field by the connecting member (20).

Fig. 8 is a side sectional view showing an installation state, and Fig. 8 is a perspective view showing a fifth embodiment of the present invention.

First, before describing the embodiment of the present invention will be described for the known polymer concrete as follows.

Polymer concrete is made of a high strength, high chemical resistance unsaturated polyester resin (UP) as a binder, shrinkage reducing agent to prevent volume shrinkage during curing of unsaturated polyester resin, and dibenzoyl peroxite (BPO) And a hardener such as methyl ethyl ketone peroxide (MEKP), silane (Silane) which promotes the bonding of organic polymer resin and inorganic aggregate, and it has a range of 5mm ~ 0.074mm and is free of foreign impurities such as organic impurities and dust. Is distributed evenly and contains calcium carbonate as filler to reduce the gap between the fine aggregates (water) of 0.1% or less, especially the coarse aggregates of diameter 10mm or less, the flow of polymer concrete and aggregates, and other release agents (form removal), glass fiber (Glass fiber), etc. are added, and the mixture is manufactured at a compounding ratio determined by a pre-mixing experiment according to the purpose of the structure. .

Such polymer concrete has higher compressive and flexural strengths than general concrete, which makes the thickness of the member thin, excellent chemical resistance, high watertightness, and excellent resistance to freeze-thawing.

The first embodiment of the present invention, which is manufactured by using the polymer concrete as a water drainage channel, has a vertical wall 11 and a bottom portion 12 and has a U-shaped channel unit as a whole as shown in FIGS. 1 and 2. (10) in the fine groove (11a) formed in at least one side end portion is fitted with a sealant (13) of rubber material for airtight, the edge of the edge facing the vertical wall (11) and the bottom portion (12) First coupling means 14 for embedding and connecting each channel unit 10 opposed to each other at both edges are embedded.

The structure in which the water stop material 13 is fitted into the fine groove 11a is equally applied to the second to fifth embodiments to be described below as well as the first embodiment.

In addition, the first joint means 14 is a support angle 14a surface-treated with stainless or zinc plating embedded at both edges of edges facing the vertical wall 11 and the bottom 12 of the channel unit 10. 14a 'and bolts 14b and nuts 14c for connection with the respective support angles 14a and 14a' so as to hermetically bond the units 10 extending in the longitudinal direction. . Although not shown in detail in the drawing, since the protruding shape of the first joint means 14 may act as a factor that can hinder the flow of water, the first joint means 14 is embedded in order to improve the flow of water. Finish molding work should be done to have the same surface.

On the other hand, the second joint means 15 may be separately configured for connection between the channel units 10 opposed to the outer upper edges of the vertical wall 11. In order to further secure the tight state between the channel units 10 to prevent leakage, the configuration of the second joint means 15 is very preferable.

The configuration of the second joint means 15 is the same as that of the first joint means 14. Specifically, the surface treatment is performed by stainless or zinc plating embedded at both outer upper edges of the vertical wall 11. Bolts 15b and nuts for connection of the respective support angles 15a and 15a 'and the respective support angles 15a and 15a' so as to hermetically bond the channel units 10 extending in the longitudinal direction. 15c, it is possible to reliably configure the tight state between the channel units 10 together with the first joint means 14.

In addition, the vertical wall 11 and the bottom 12 of the channel unit 10 is preferably formed integrally with each other.

On the other hand, as shown in Figure 3 and 4, the second embodiment of the present invention, the vertical wall 11 and the bottom portion 12 of the channel unit 10, if necessary for the reinforcement of the tensile resistance to the side wall earth pressure At the same time, the reinforcing bars 16 at equal intervals may be disposed at the same time, and the protruding ribs 17 may be formed on the outer side of the vertical wall 11.

Meanwhile, as shown in FIG. 5, in the third exemplary embodiment of the present invention, the vertical wall 11 of the water channel unit 10 is installed from the bottom portion 12 so as to withstand the sidewall earth pressure. Has a configuration in which the tapered portion 18 is formed.

Meanwhile, as shown in FIGS. 6 and 7, the fourth embodiment of the present invention integrally includes a buoyancy prevention rib 19 that protrudes out of a predetermined length to the bottom portion 12 of the channel unit 10. It has a formed configuration.

Meanwhile, as shown in FIG. 8, in the fifth embodiment of the present invention, the vertical wall 11 and the bottom portion 12 of the channel unit 10 are limited to the channel unit 19 in which the buoyancy preventing ribs 19 are formed. ) Is not integral but has a configuration that can be assembled in the field by a separate connection member 20. Specifically, the outer side of the vertical wall 11, when assembled to the bottom portion 12, the triangular support ribs (11b) are integrally formed to improve the support state, the connecting member 20 is the vertical wall (11) It has a configuration that is fastened and fixed between the support rib (11b) and the bottom portion (12).

The operation of the present invention configured as described above will be described.

Polymer concrete drainage system according to the present invention is produced by a mold of a certain form (eg, c-shape). This is the water drainage of the second embodiment, which is the water drainage of the second embodiment in which the reinforcing bar 16 is embedded in the channel unit 10 and the protruding ribs 17 are formed on the outer wall, and the tapered portion 18 having a constant slope is formed. For example, the water drainage can be applied to the water drainage of the fourth embodiment in which the buoyancy preventing ribs 19 are integrally formed on the bottom portion 12, and in particular, a sealant which secures the tight state between the waterway units 10 to prevent leakage. 13 is preferably a prefabricated to fit directly into the fine groove (11a) of the channel unit 10 formed in the molding process in the groove, the first joint means for connection coupling between the channel unit 10; The support angles 14a and 14a 'of (14) and the support angles 15a and 15a' of the second joint means 15 may be embedded so as to be integrated together at the corresponding positions in the molding process of each embodiment. desirable.

On the other hand, the channel of the water drainage channel of the fifth embodiment is not suitable for the manufacturing process of the above embodiment because each of the vertical wall 11 and the bottom portion 12 is a dichotomous structure that can be assembled in the field, but not separately. It will have to be manufactured in vertical wall molds and bottom molds. In this process, the sealant 13 is fitted to the fine grooves 11a formed together with each cross-section at the time of forming each member (vertical wall and bottom). The support angles 14a and 14a 'of the first joint means 14 and the support angles 15a and 15a' of the second joint means 15 for the connection coupling between the parts 10 are also not an embedding structure but an assembly structure. Would be more suitable.

In the process of installing the channel unit 10 of each embodiment to be molded in the longitudinal direction as shown in FIG. 2, the sealant 13 embedded in the cross section of the channel unit 10 in the longitudinal direction before and after Support angles 14a and 14a 'by using the bolts 14b and nuts 14c of the first joint means 14 at the lower side of the channel unit 10 so that the other channel units 10 positioned may be in close contact with each other. And the support angles 15a and 15a 'are completely engaged using the bolts 15b and the nuts 15c of the second coupling means 15 on the upper side of the channel unit 10. This will prevent leakage at the source. The above operation applies to all of the first to fifth embodiments of the present invention.

In the second embodiment of the present invention, since the reinforcing bar 16 is embedded at regular intervals over the vertical wall 11 and the bottom 12 of the water channel unit 10, The side wall earth pressure applied prevents abnormal deformation and breakage of the vertical wall 11 in advance. In addition, the protruding ribs 17 formed on the outside of the vertical wall 11 also serve as a reinforcing structure capable of withstanding the sidewall earth pressure, and at the same time, increase the tensile resistance by the earth pressure, thereby making it more robust.

On the other hand, in the third embodiment of the present invention, since the tapered portion 18 of constant inclination is formed on the vertical wall 11 of the channel unit 10, the structure is resistant to sidewall earth pressure. Will be made. This has the same effect as the second embodiment described above.

On the other hand, since the fourth embodiment of the present invention has a structure in which the buoyancy preventing rib 19 is formed integrally with the bottom portion 12 to protrude more than the position of the vertical wall 11, the external water level unit 10 The buoyancy prevention ribs 19 can be prevented from penetrating toward the bottom portion 12 of the channel) so that the channel unit 10 itself floats. That is, as shown in FIG. 7, the buoyancy prevention rib 19 can prevent the waterway from being damaged against the buoyancy acting on the waterway unit 10 by relying on earth pressure being loaded. In addition, although not shown in the drawings, the application of the buoyancy preventing rib 19 may be applied to the bottom portion 12 of the channel unit 10 of the third embodiment (Fig. 5) in which the tapered portion 18 is formed.

On the other hand, the fifth embodiment of FIG. 8 is the connection member 20 in the field in the state that the support rib 11b and the buoyancy prevention rib 19 of the vertical wall 11, which is composed of the channel unit 10, are separately manufactured. Since the structure is assembled by using a particularly small volume is advantageous for transportation, and also has the advantage that the maintenance cost is reduced because the breakage of a part can replace only that part.

In particular, the fifth embodiment is applicable to the channel unit 10 having the buoyancy preventing ribs 19.

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

Applying the present invention as described above, it is possible to reliably block the leakage of water flowing along the channel by the configuration of the water supply unit of the channel unit cross section and the configuration of the first joint member and the second joint member for coupling between the unit and the unit. In addition, it is possible to prevent abnormal deformation caused by sidewall earth pressure due to reinforcement of the reinforcing bars and the formation of the tapered portion of the vertical wall. Even if buoyancy is applied, it is completely dependent on the earth pressure, so it does not float and solves the problem that the waterway itself is broken.In the case of the field assembly type, it is easy to transport due to the small volume before assembly and part of the waterway unit. In case of breakage, only the damaged part can be replaced without having to replace the whole. There can be expected advantage that maintenance is significantly reduced (effects described for the polymer concrete has fully hayeoteumeuro described earlier for this technique is omitted.)
