Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a road isolation pier, including more than two isolation pier units 100, where the bottom of each isolation pier unit 100 is provided with a connecting groove 101, and the connecting groove 101 is arranged along the connecting direction of the isolation pier units 100; fixed to the ground, cooperating with a connecting channel 101 for fixing a connecting piece 102 of the hard shoulder unit 100.

The embodiment of the utility model provides a road isolation pier, because all there is a connecting groove 101 at the bottom of each isolation pier unit 100, the connecting groove 101 is arranged along the direction of the connection of the isolation pier units 100; and a connecting member 102 is fixed to the ground, which is engaged with the connecting groove 101, for fixing the hard shoulder unit. Compared with the prior art, firstly, the connection of the isolation pier is very simple, and only the connection groove 101 is required to be sleeved on the connecting piece 102; secondly, because the connection of the hard shoulder units is realized by adopting the mode that the connecting piece 102 is matched with the connecting groove 101 at the bottom, the stability of fixing the hard shoulder units and the ground can be ensured, the stability of connection between the hard shoulder units is also ensured, and the isolation effect and the safety performance are greatly improved.

It should be noted that, in the embodiment of the present invention, when the connecting groove 101 is sleeved on the connecting part 102, the connecting groove 101 can restrain the connecting part 102, that is, unless the hard shoulder unit 100 slides along the connecting part 102, the connecting part 102 cannot move out of the connecting groove 101.

In order to achieve the above effect, the coupling groove 101 may be constructed such that the width of the opening of the coupling groove 101 near the bottom surface of the pier unit 100 is smaller than the width of the inside of the coupling groove 101. For example, the cross section of the connecting groove 101 may be a sector, an inverted triangle, or a prism.

In the embodiment of the present invention, the cross section of the connecting groove 101 is trapezoidal, and the shorter side of the trapezoid is disposed at the bottom of the hard shoulder unit 100; at this time, the connecting member 102 also has a trapezoidal cross section, which is sized to fit the connecting groove 101. With this structure, firstly, the fixing of the connecting member 102 to the ground is facilitated, and secondly, the pier unit 100 can be ensured to be restrained in three dimensions to improve the stability.

It should be noted that, the connecting member 102 may be fixed to the ground by bolts and nuts, or by other similar and alternative methods. The manner in which the connector 102 is secured to the ground is known in the art and will not be described in detail herein.

In the embodiment of the present invention, the connection member 102 may be fixed to the hard shoulder unit 100 in the following manner. A fixing hole is arranged on the hard shoulder unit 100; a fixing member for fixing the hard shoulder unit 100 and the connecting member 102 through the fixing hole is provided on the connecting member 102. The specific structure of the fixing member and the manner of fixing the hard shoulder units 100 and the connecting members 102 through the fixing holes are the prior art, and are not described herein again.

In the embodiment of the present invention, the isolation pier unit 100 is provided with the through hole 103, and the through hole 103 and the connecting groove 101 are arranged in the same direction.

The through holes 103 not only greatly reduce the weight of the hard shoulder unit 100, but also greatly reduce the production cost. Above all, the arrangement of the through holes 103 enables the hard shoulder unit 100 to have a buffering function, and when a vehicle collides with the hard shoulder unit 100, buffering and energy absorption can be performed, so that the occurrence of secondary damage is greatly reduced.

The isolation pier unit 100 of the embodiment of the present invention comprises a lower pier body 110 and an upper pier body 120, wherein the upper pier body 120 is smaller than the lower pier body 110; the connection between the upper pier body 120 and the lower pier body 110 is transited by a connection cambered surface 130.

Wherein, the functional surface of the upper pier body 120 comprises a top surface 121 which is horizontally arranged; a first side 122 disposed vertically; the top surface 121 and the first side surface 122 are transited by a first arc surface 123.

Wherein, the functional surface of the lower pier body 110 comprises a bottom surface 111 which is horizontally arranged; a second side 112 disposed vertically; the second flank 112 transitions via a second arc 113 to a connecting arc 130.

The functional surface in the present embodiment is a surface that may come into contact with a vehicle when the vehicle collides with the pier unit 100.

The upper pier body 120 is smaller than the lower pier body 110, and the arrangement of the first arc surface 123, the second arc surface 113 and the connecting arc surface 130 can reduce the secondary damage caused in the collision process of the trolley and the hard shoulder unit 100, and greatly improves the safety.

Wherein, the embodiment of the present invention provides a through hole 103 on the upper pier body 120 and the lower pier body 110.

The hard shoulder unit 100 in this embodiment is formed by clay extrusion molding and firing. Due to the fact that clay extrusion molding is adopted, compared with the existing isolation pier formed by pouring cement, the length of the isolation pier unit 100 can be controlled as required, and the connecting groove 101 and the through hole 103 in the bottom of the isolation pier unit 100 are easy to achieve.

In addition, the clay has natural red color, and the surface of the fired isolation pier unit is fine, smooth, beautiful and beautiful.

The connecting member 102 in the embodiment of the present invention is made of wood or metal.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
