Description

Roadside weed mat {WEEDER MAT APPARATUS}

The present invention relates to a weed-proof mat, and more particularly, to prevent weed growth by covering the ground around road facilities such as roadsides, shoulders, guide rails, and electric fences to prevent plants from invading roadside vegetation suppression ( It relates to a system and method for plant growth inhibition) (WEEDER MAT CONSTRUCTION METHOD AND APPARATUS). In general, guardrails are installed on roadsides to prevent vehicle accidents, and traffic safety facilities for safe driving of drivers are installed on the guardrails at regular intervals. However, in the case of guardrails on highways, national highways, and local roads outside the city center, it is not easy to clearly recognize the guardrails in the driver's field of view due to the wild growth of weeds in spring, summer, and autumn, and also, traffic safety facilities are obscured. The occurrence of impossible cases has become a cause of traffic accidents. In addition, each management entity of each road puts in manpower to remove these weeds and performs periodic weeding, but due to the vigorous self-sustaining of the weeds, 2 to 3 weeks after weeding, traffic safety facilities grow again to the point of being impossible to identify. As a result, the efficiency of the mowing operation decreases. In addition, huge expenses are required for continuous mowing, and it is difficult to guarantee the safety of workers working on the roadside.

Weeds growing on highways or roadsides cause traffic accidents by corroding or damaging traffic facilities or obstructing a driver's view while driving a vehicle. In particular, roadsides where guardrails are installed are in an optimal state for the growth of weeds due to severe exposure of the soil and a lot of sunlight, so there is an inconvenience that weed removal work must be performed at any time. In order to prevent this, weed control mats are installed on roadsides where guardrails are installed to suppress the growth of weeds. The anti-weed mat not only suppresses the growth of weeds, but also improves roadside aesthetics and prevents deformation of road structures by blocking radiant heat. prevent that In general, mats made of non-woven fabric, fiber materials, synthetic resins, etc., or plate-proof mats (weeding mats, weed mats, vegetation suppression mats, weed control plates) have one end fixed to the post of a pillar or guardrail, and the other end nailed or The construction is carried out in a way that is driven into the ground with spikes and fixed.

In general, the road 100 includes a pavement surface 110; boundary stone 120; and roadside 130; In addition to this, the guardrail 140; Woldam prevention fence (200); Or a grass-proof mat (300); Configurations such as may be additionally installed. See Figure 1.

The pavement surface 110 may be paved with a member such as asphalt or cement to help vehicles run; The boundary stone 120 may be installed at a predetermined height to prevent vehicles from encroaching on the edge of the pavement surface 110 along the longitudinal direction of the road 100 (longitudinal direction of the road); The roadside 130 can be distinguished from the pavement surface 110 by the boundary stone 120, and is arranged along the length of the road 100 by constructing soil to support the pavement surface 110, Including a horizontal surface 131 extending from the edge boundary stone 120 and a slope 132 built inclined downward from the horizontal surface 131; It can be done.

The guardrail 140 may include a holding 141 and a guardrail plate 142,

The pillars 141 are rods or rod-shaped pillars made of a member such as metal, and are spaced apart from each other in the longitudinal direction of the road 100 at regular intervals (equal intervals) or, if necessary, at separate intervals (different intervals). It is installed to be upright (erected) on the horizontal surface 131 of the roadside 130, and the guardrail plate 142 is a plate member made of metal or the like that is continuously and extended in the longitudinal direction of the road 100, and the support 141 ) It is installed at the top of the support 141 so as to be supported and supported by a function to prevent the vehicle that has crossed the boundary stone 120 from leaving the road 100.

The wall damage prevention fence 200 may include a vertical portion 210 installed vertically at the bottom of the holding 141 and may additionally include a sloped portion erected obliquely from the top of the vertical portion 210, and the animal may be on the road ( 100), that is, it may be installed so as not to enter the pavement surface 110. The vertical portion 210 of the anti-wolf fence 200 may be provided with a transparent member such as transparent acrylic. In this case, the driver can secure a view across the guardrail 140, so he can feel less stuffy. In addition, during the unavoidable mowing operation, the blade of the lawn mower prevents direct collision with the post 141 of the guard rail 140.

In particular, the grass-proof mat 300 includes a mat portion 310 in the form of a mat or pad that directly covers and covers the ground and roadside 130; A fixing part 320 for fixing the mat part 310 to the holding 141; It may be included, and in order to suppress the growth of weeds 150 growing on the roadside 130, a plurality of them may be installed by continuously arranging them in the longitudinal direction. That is, one unit (one) grass-proof mat 300 / mat part 310 is placed between the two posts 141, and another grass-proof mat 300 / The mat portion 310 is placed and arranged continuously.

The fixing part 320 may be formed on both sides (one side and the other side) of the weed-proof mat 300 / mat part 310 in the longitudinal direction (longitudinal direction of the road). It is formed on both sides and can take a different (asymmetric) form, and a binding portion 321 may be formed on one side of the mat portion 310, and an adjustment groove 322 may be formed on the other side. See Figure 2.

The binding part 321 is for binding the mat part 310 to the support 141, may include a cutout groove 321a and a fitting hole 321b, and may take the form of a key as a whole as illustrated in the drawings. .

The incision groove 321a may be formed in a straight line along the length of the mat portion 310 in the longitudinal direction, and the gap of the incision width is formed narrower than the outer circumferential width of the post 141, through which the post 141 ) is configured to pass through and reach the fitting hole (321b). At this time, the incision groove 321a is opened on both sides to insert and pass the post 141, and the post 141 is formed narrow enough to pass through, so that the weeds protrude through the gaps of the incision groove 321a that is closed again It is desirable to narrow the gap as much as possible so that it does not come out (exit, grow).

The fitting hole 321b may be formed through a hole in the inner end of the incision groove 321a. The fitting hole 321b takes a shape corresponding to the outer periphery of the post 141 and has a size greater than or equal to the outer periphery. For example, if the cross section of the post 141 is circular as illustrated in the drawing, it is preferable to take a circular shape of the incision groove 321a to prevent weeds from protruding through the gap between the post 141 and the fitting hole 321b. At this time, in order to cover up the gap between the post 141 and the fitting hole 321b or bind the mat part 310 to the post 141 in close contact, a ring-shaped binding piece r1 may be separately provided and fastened.

The adjustment groove 322 is necessary to perform fine adjustment of the distance when the length of the mat part 310 and the separation distance (separation distance) between the struts 141 arranged in series do not match. The control groove 322 has a predetermined width along the length of the mat part 310 in the longitudinal direction and may be cut in a straight line, and the example in the drawing takes a U shape. The control groove 322 may take at least the same width as the outer circumferential width of the holding post 141 and take a larger width for the convenience of intervening work.

At the time of installation, when the fastening part 321 provided on one side of the mat part 310 is fixed to one post 141 and the position of the mat part 310 is determined, the other post 141 is mat part 310 While being interposed in the control groove 322 provided on the other side of the may be installed in a way that the spacing is matched. In terms of the post 141, from one side of the post 141, the binding part 321 on one side of one mat part 310 is interposed and coupled, and from the other side of the post 141, the other mat part 310 ) The distance can be adjusted while the control groove 322 on the other side is interposed and coupled. Let's find out how to install and configure in detail with the examples of FIGS. 2 to 4 .

First, prepare a plurality of the anti-fog mats 300 of the above-described configuration necessary for installation and wait at the road site.

After entering the construction, one of the first grass-proof mats 300 (a1) among the waiting mats 300 is placed between the first posts 141 (b1) and the second posts 141 (b2). However, here, the first grass-proof mat 300 (a1) specifies an arbitrary one for convenience of explanation among a number of series of plural grass-proof mats 300, and other grass-proof mats 300 (a0) may exist before that. And in the same way, the same is true for the holding 141.

When the arrangement is completed, the cutout 321a of the binding part 321 configured on one side of the mat part 310 of the first weed-proof mat 300 (a1) is pulled sideways or in the opposite direction up and down to create a gap (gap, After inserting the first post 141 (b1) after opening the gap) and inserting the first post 141 (b1) to reach the fitting hole 321b (m1), fitting of the fastening part 321 The ball 321b is installed so that the first post 141 (b1) is interposed therebetween, and the gap of the incision groove 321a is returned to the original position to be narrowed and bound to the first post 141 (b1). See Figure 2B.

And while bringing the control groove 322 configured on the other side of the mat part 310 of the first grass-proof mat 300 (a1) to the second post 141 (b2) side (while inserting) the first post 141 Adjust the distance (m2) by matching the distance (interval) with (b1). That is, by adjusting the distance between the fixing parts 320 on both sides of the anti-corrosion mat 300 and the distance between the posts 141, the distance is adjusted by inserting the posts 141 deeply into the control groove 322 or interposing them a little ( m2) can be taken. See Figure 4A.

Next, among the grass-proof mats 300 in standby, the second grass-proof mat 300 (a2) is disposed between the second holding posts 141 (b2) and the third holding posts 141 (b3). And, in the same way as before, open the gap in the incision groove 321a of the binding part 321 configured on one side of the mat part 310 of the second weed-proof mat 300 (a2) to insert the second post 141 (b2). Insert and pass through so that the second post 141 (b2) is firmly inserted into the fitting hole (321b) of the coupling part 321 and interposed, and the incision groove (321a) is again narrowed to the second post (141) (b2). to settle At this time, as shown in the drawing, the other side of the first weed-proof mat 300 (a1) and the one side of the second weed-proof mat 300 (a2) are overlapped and overlapped, so that either one of the fixing parts 320 of the weed-proof mat 300 ) Even if the width of the incised gap of the control groove 322 is large, the incision groove 321a of the fixing part 320 of the other weed-proof mat 300 is sufficiently narrow or only incised without a gap. Since it is provided, the incision groove 321a conceals and covers the exposed gap. On the other hand, as illustrated in the drawing, the other side of the first grass-proof mat 300 (a1) may be arranged to be placed under one side of the second grass-proof mat 300 (a2), but may be placed on the contrary.

And, using the control groove 322 formed on the other side of the mat part 310 of the second grass-proof mat 300 (a2), the second support ( 141) (b2) and adjust the distance. In this way, it is possible to install the grass-proof mat 300 continuously.

In addition to the example of FIG. 4A, the part of the roadside 130 that can be exposed to the outside through the gap of the control groove 322 of the weed-proof mat 300 becomes an aura wrap, and by the side of the overlapping incision groove 321a Since it is covered, it can be concealed. For this purpose, it may be more effective to cut the incision groove 321a in a straight line using a cutting means such as a knife or scissors rather than making a gap by digging a groove.

And, depending on how deeply the holding posts 141 are interposed in the control grooves 322, the distance between the length of the weed-proof mat 300 and the holding posts 141 can be adjusted (m2). To this end, the drawing shows an example of adjusting the distance (m2), that is, adjusting the distance while moving the position along the length of the control groove 322 by interposing the support 141 in the control groove 322 having a U-shaped groove. .

In addition, in the example of FIG. 4B, when the road is a curved road, the first anti-chopped mat 300 (a1) and the second anticorrosive mat 300 (a1) centered on the fitting hole (321b) and the control groove (322) in which the post (141) is interposed. It shows a case of adapting to a curved road by arranging the weed-proof mat 300 (a) while performing angle adjustment (m3) by bending (bending) at an appropriate angle corresponding to the curve.

The following will be described with reference to FIGS. 5 and 6 according to another embodiment. First, in relation to the direction, the side of the pavement surface 110 or the boundary stone 120 of the road 100 in FIG. ) to be determined. Meanwhile, it should be noted that in the drawings of FIGS. 5 and 6, unlike FIGS. 2 to 4, the locations of the fastening portion 321 and the control groove 322 are reversed.

To keep the ground dry on the bottom of the weed-proof mat 300, release moisture to the outside (mainly the upper part) of the mat part 310, or use the weed bearing capacity to make the weed-proof mat 300 better In order to fix to the ground, a vertically perforated open groove 331 may be formed in the mat portion 310 of the grass-proof mat 300, and a plurality of Although it is possible to provide a regular opening groove 331 by drilling a hole, in many cases the opening groove 331 is not necessary, so in the present invention, the selectable opening and closing portion 330 allows to determine the situation at the construction site and take action at the site. ) to provide a configuration.

As shown in FIG. 5A, the opening and closing parts 330 are formed in plurality by being spaced apart from the mat part 310 of the weed-proof mat 300 at predetermined intervals, and the mat part 310 has a substantially rectangular shape or a thumb shape. It is formed by incision (e1). At this time, the left and right sides, including the roadside side (s2) side, are cut and separated from the mat part 310, but the roadside side (s1) side is not cut and maintained in a connected state, and this connected part of the road 100 The axis is placed parallel to the longitudinal direction and serves as a bending axis (e2) that can be folded or unfolded by bending (refracting) to the road side (s1) using it as a hinge. In this way, one side is connected to the mat portion 310 and the other side is formed with an opening/closing portion 330 cut from the mat portion 310 . In addition to this, a longitudinal groove is formed on the bottom surface of the refraction axis e2 so that the folding action can be performed more easily. See FIGS. 5B and 5C in this regard.

If the open groove 331 is not needed using the opening and closing part 330, leave it as it is as shown in FIGS. 5A and 5B to cover (cover) the ground, and if the open groove 331 is needed, FIG. 5C and Likewise, the opening groove 331 may be provided by pulling (opening) the opening/closing part 330 upward to apply the opening (e3) operation, and the opening (e3) may be all as shown in FIG. 6A or in the case of FIG. 6B You can select only some of them, such as When the opening and closing part 330 lying down is bent up and opened (e3), the body of the opening and closing part 330 escapes and the opening groove 331 is provided, and at the same time, the body of the opening and closing part 330 acts as a curtain blocking the side of the road side (s1) Do it. Accordingly, the weeds 150 growing through the opening groove 331 are blocked by the body of the opening and closing part 330 and do not grow well toward the road side s1.

At this time, as shown in FIG. 5C, the opening and closing part 330 may be tilted (inclined) and configured (installed) to maintain the open (e3) state at an acute angle (e0) less than a right angle (90 degrees). Accordingly, as shown in FIG. 5D, after the opening (e3) of the opening and closing unit 330, the opening and closing unit 330 presses and presses the weed 150, that is, the pressing action (e4) can be continuously applied, more effectively It is possible to suppress weeds 150 from growing on the road side s1 or prevent them from growing and extending. That is, it is possible to prevent the weeds 150 from approaching the guard rail 140 well in advance. As a result, the weeds 150 grow inclined only in one direction on the roadside side (s2), and the action of supporting the mat portion 310 of the weed-proof mat 300 continues to be performed.
