Description

Assembly Products of Manhole Recycled Waste-vinyl}

The present invention relates to a prefabricated manhole article using waste vinyl.

Vinyl used for agricultural and industrial purposes is mainly used as polyethylene as its main component, and its amount is increasing every year. However, it cannot be effectively treated, and environmental pollution is aggravated. On the other hand, the conventional waste vinyl is collected (washed), cut and melted for reuse, manufactured in the form of chips, and then used in part for injection into guardrails, barriers, separators, lightweight aggregates, and the like.

The present invention is one of the ways to expand the use of waste vinyl, the conventional construction of the main components of the underground manholes, such as water pipes, guide sockets and slidable sockets made of waste vinyl, the work that follows the construction of concrete in the construction site The present invention was completed after researching on the problem that it can solve the problems such as inconvenience of the top, excessive manufacturing cost and air delay due to curing time.

Conventional techniques for manholes using waste vinyl include Korea Utility Model Publication 92-122 44 (Industrial Waste Material Mold Manhole) and Korea Utility Model Publication 96-37584 (Manhole Cover Using Waste Synthetic Resin), but most of the manholes themselves are It is about. On the other hand, Korea Utility Model Publication 96-3303 (Prefabricated Water Dispensing Manhole) relates to a water dispensing manhole assembled into a support pipe supporting the main pipe and the water dispensing valve with a cut-out groove. The dividing manhole of 18254 has been previously filed with a dividing manhole for pre-fabricating the foundation and supporting pipes and other structural parts in advance, but the technical configuration is different from the present invention.

The present invention provides a prefabricated manhole product by separately manufacturing wastewater taps, sliding sockets, and guide sockets by recycling waste vinyl, and is easy to install. It aims to improve work efficiency. On the other hand, another object of the present invention is to recycle waste vinyl, as well as to benefit from the economic aspect, to contribute to the prevention of environmental pollution by using environmentally friendly resources.

The present invention manufactures a manhole article by washing, crushing, dehydrating, melting, compressing, regenerating and molding waste vinyl. The description of these processes is as follows.

Waste Vinyl Treatment and Mold Manufacturing

By using pre-crusher and high pressure water washer to remove foreign matters first, the efficiency of removing foreign substances in the pretreatment is maximized, minimizing the capacity of main treatment and after-treatment facilities and minimizing the required process quantity to maximize the overall process efficiency. The crushed and sorted waste vinyl is completely separated to facilitate the separation of foreign substances through the repeated process of grinding and washing (cleaning) movement, and then the waste vinyl containing a large amount of moisture is washed out within 10% of water content through the washing and grinding process. The waste vinyl is melted and melted, and extruding and regeneration is performed to cut and discharge the molten waste vinyl to a certain size. Extruded recycled vinyl is injected into a mold of the desired shape to produce a manhole article such as a water gage 20, a slid socket 30 and a guide socket 31. Figure 2 shows the gutter 20 of the present invention, Figure 3 shows a guide socket 31, Figure 4 shows a squeeze socket 30.

<Waterworks>

In order to correspond to the angles of all the inlet pipes, the shape of the conduit 20 is a combination of seven basic types as shown in Figs. 8A to 8G and 7 basic types as shown in Fig. 8B. ) Basic type taps are manufactured as a manhole assembly like a sphere or bottom plate so that they can correspond to the angles of all inlet pipes.

Fig. 9 shows how the seven basic types of the A to G water taps 20 correspond to the angles of the inflow pipes. If there is a pipe flowing into the manhole at an angle of 120 ° and 270 °, Therefore, it is possible to cope with the BG combination-type tap of Figure 8 (b). This principle can correspond to an angle of ± 13 ° in one basic type, but can also correspond to ± 20 ° due to the shape of the tap shown in FIGS. 10 (a) and 10 (b). Even if it varies in a variety of shapes that can be flexibly connected to the streamline (central bulge shape) can respond according to the shape of the tap. In addition, it is designed so that dirt can flow flexibly even with a small amount of water by widening the center part and changing the shape of the cross section.

As shown in Fig. 9, the structure of the tap is A type (87 ° to 116 °), B type (114 ° to 143 °), C type (140 ° to 169 °), D type (167 ° to 196 °), E 7 types of basic type (194 ° to 223 °), F type (220 ° to 249 °), G type (247 ° to 276 °) and combination type such as AG type, BG type, ADG type combined Can correspond to the angle of the tube. In addition, since the tap is wider from the upstream to the center and has a swollen shape, it is possible to cope with inflow angle of ± 13 ° with one basic type, and even if the position of the manhole is unavoidably changed due to obstacles, etc. If you adjust the position in the construction as it is possible.

The reason why the tap can correspond to the inlet angle of ± 13 ° in the above described with reference to the B type of the seven basic types of taps as follows. Type B has an allowable angle deviation of 143 °-114 ° = 29 °, and maximum angle of 143 ° of Type B and 140 ° of Minimum Type of C is overlapped by 3 °, so it is 29 ° -3 ° = 26 ° and calculated from the centerline. 26 ° ÷ 2 = 13 °. In other words, even if the inlet and the inlet of the water inlet is 13 degrees wrong, the inlet can be smoothly discharged into the shape of the water inlet of the present invention, the shape of the short life of the central part is wide and swollen.

On the other hand, when installing the manhole, while the intersection of the upstream and downstream pipes coincides with each other, as shown in FIG. 11 after installing the manhole according to the conventional method, as shown in FIG. 12 showing the case where the manhole is installed by using the tap of the present invention. On the extension of the pipe and the upstream pipe, the downstream and upstream ports of the manhole channel should be coincident, and the intersection of the downstream and upstream pipes will not coincide with the center of the manhole. The intersection of the downstream and upstream pipes does not coincide with the center of the manhole, because the flow channel of the channel is flexible to smooth the flow of water. In addition, the drilling location of the downstream pipe and the drilling location of the upstream pipe will be supplied as a ready-made product (refer to FIGS. 8 (a) and 8 (b) for drilling angles and see Table 1 for drilling locations). Needs to be changed by

<Guide socket>

The guide socket 31 serving as an inflow pipe into which the sewage flows into the manhole has a shape as shown in FIG. 3, which is inclined to the inlet wall of the sphere or is embedded horizontally so as to be connected to the pipe and is 30 cm to 60 cm than the outlet of the sewage. Position it slightly higher so that there is a drop. The upper end of the guide socket is a needle-shaped ('b') cut structure, which can flexibly flow down when the sewage flows into the manhole, and the inlet pipe can be expanded without the need for modification of the tap. In addition, it is possible to improve the flow of sewage by allowing sewage to flow into the flow path of the tap. On the other hand, when there is a drop in the discharge pipe, the inlet part is connected to the guide socket 31, the outlet part is the fold socket 30, but when there is no free fall, the inlet, discharge part is connected to the fold socket.

<Welding socket>

Sliding socket 30 is a fitting of the shape as shown in Figure 4 (Fittings) to be embedded in the discharge wall of the sphere to be connected to the pipe and as shown in Table 1 the use of the squeezing socket (31) than the inlet (discharge) diameter Since there is a cursor margin, the above-mentioned allowable angle can be rotated up, down, left, and right up to ± 13 °, and it is easy to cope with the change of manhole. Therefore, even when there is a construction error even when laying the pipe can be installed without any problems.

<Application example>

* Excavation; As shown in Fig. 13, the excavation width for manhole installation normally takes a 200mm margin on both sides of the manhole outer diameter. Change the ground elevation given from the pipeline diagram according to the following equation.

D = 15-450 × a ‰ (D is the depth to change, a is the downstream gradient)

15: car from the center to the downstream

450: No. 1 manhole radius

* Rubble foundation; After confirming the excavation depth or the positional relationship between the centerline of the inflow pipe and the outflow pipe and the manhole, when the predetermined depth is confirmed, the rubble is laid and sufficiently compacted.

Bottom plate installation; After setting upstream and downstream position and adjusting horizontal and height, mark upstream and downstream on bottom plate. The bottom plate is set so that the downstream and upstream ports of the manhole are simultaneously placed on the extension lines of the downstream and upstream pipes.

* Waterway installation; Mark upstream and downstream on the bottom plate in advance and set upstream and downstream of the tap.

• installation of bottom plates and spheres (pipe connecting walls); The joints are cleaned with a brush, the watertight packing or the water caulking agent is set on the bottom plate, and then a sphere (pipe connection wall) is placed on the bottom plate on which the pot is placed. In this case, the spheres are adjusted so that the upstream and downstream of the conduits coincide with the perforations of the spheres.

Installation of guide sockets; A guide socket is embedded in the upstream conduit on the left side of the sphere and the seam ends with an exponential packing or expulsive caulking agent.

Installation of slid sockets; The fusion socket is embedded in the downstream conduit connector on the right side of the sphere and the seam ends with an exponential packing or expulsive caulking agent.

* Wrap-up; After connecting the prefabricated manhole supplies and the sphere, the installation of the tap is completed by installing and refilling the ladder and manhole cover.

The prefabricated manhole of the present invention is easy to use because it can be easily installed by assembling the water tap, sliding and guide sockets together. In addition, durability and workability can be improved. In addition, it is possible to supply environmentally friendly products that recycle waste vinyl.

In addition, the tap of the present invention has a wide and swollen shape from the upstream to the center, so that it can cope with various inflow angles, and even if it is inevitable to change the position of the manhole due to obstacles, etc., within the allowable range of the angle. If you adjust the position, it can be installed as it is.
