[0040] To enable those skilled in the art to better understand the technical solutions in this application, the following will describe the technical solutions in the embodiments of this application in detail with reference to the accompanying drawings in the embodiments of this application. The described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

[0041] Embodiment 1

[0042] As Figure 1 and Figure 3 shown, a prefabricated and assembled anti-collision pier includes a plurality of anti-collision walls 111 connected end to end in sequence, and the plurality of anti-collision walls 111 form a closed-loop structure and surround the outside of the facilities for line erection. Exemplarily, the facilities for line erection are steel pipe poles 2, that is, the anti-collision pier forming a closed-loop structure surrounds the outside of the steel pipe poles 2.

[0043] As a specific implementation manner, the prefabricated and assembled anti-collision pier described in this embodiment is composed of two anti-collision walls 111.

[0044] As Figure 3 and Figure 4 shown, the anti-collision wall 111 includes a main body portion 1111, a first connection end 1112 is provided at one end of the main body portion 1111, and a second connection end 1113 is provided at the other end of the main body portion 1111. The first connection end 1112 of the anti-collision wall 111 is fixedly connected to the second connection end 1113 of the adjacent anti-collision wall 111 through a connection component.

[0045] As Figure 10 and Figure 13 shown, the connection component includes two connection steel plates 121, the first connection end 1112 and the second connection end 1113 are both clamped between the two connection steel plates 121, and the first connection end 1112 and the second connection end 1113 are both fixedly connected to the connection steel plates 121 on both sides through a locking component 122.

[0046] The described locking assembly 122 includes a stud 1221, and a first mounting hole 1114 for accommodating the stud 1221 is provided on the anti-collision wall 111. The stud 1221 is disposed within the first mounting hole 1114, and both ends of the stud 1221 pass through the connecting steel plate 121 and extend to the outside of the connecting steel plate 121 (taking the side where the two connecting steel plates 121 face each other as the inner side). A second mounting hole for accommodating the stud 1221 is provided on the connecting steel plate 121. A locking nut 1222 is provided on the outside of the connecting steel plate 121 (taking the side where the two connecting steel plates 121 face each other as the inner side) of the stud 1221, and under the locking action of the locking nut 1222, the connecting plate is pressed and fixed on the anti-collision wall 111.

[0047] Further, in order to improve the connection strength between two adjacent anti-collision walls 111, both the first connection end 1112 and the second connection end 1113 are fixedly connected to the connecting steel plates 121 on both sides through multiple sets of locking assemblies 122. As a specific implementation manner, in this embodiment, the multiple sets of locking assemblies 122 for connecting the first connection end 1112 and the connecting steel plate 121 are arranged in a straight line along the vertical direction; the multiple sets of locking assemblies 122 for connecting the second connection end 1113 and the connecting steel plate 121 are arranged in a straight line along the vertical direction.

[0048] Further, in order to ensure that the connecting steel plate 121 can be well attached to the anti-collision wall 111, both the first connection end 1112 and the second connection end 1113 of the anti-collision wall 111 are of a straight structure, that is, the inner and outer sides of the first connection end 1112 and the second connection end 1113 are both planes and are parallel to each other.

[0049] As a specific implementation manner, in this embodiment, the main body portion 1111 of the anti-collision wall 111 is of an arc structure, and both the first connection end 1112 and the second connection end 1113 are tangent to the main body portion 1111.

[0050] Further, since both the connecting steel plate 121 and the locking assembly 122 are made of metal materials, they are prone to rust in the outdoor environment, which reduces the connection strength. To solve this problem, as Figure 3 and Figure 11 shown, a concrete protection layer 13 is provided at the connection of two adjacent anti-collision walls 111, and the connecting steel plate 121 and the locking assembly 122 are wrapped within the concrete protection layer 13. Preferably, the concrete protection layer 13 is made of plain concrete.

[0051] Further, for the convenience of construction, as Figure 10 and Figure 14As shown, baffles 14 straddling the crash barrier 111 are respectively arranged on both sides of each connecting component. The baffle 14 includes a horizontal portion located above the crash barrier 111. Vertical portions perpendicular to the horizontal portion and extending downward are respectively arranged at both ends of the horizontal portion. The horizontal portion and the vertical portions together form a U-shaped structure with an opening facing downward, and the upper end of the crash barrier 111 is inserted into the U-shaped structure. The lower end face of the horizontal portion is in contact with the upper end face of the crash barrier 111, the vertical portion located outside the crash barrier 111 is in contact with the outer side face of the crash barrier 111, and the vertical portion located inside the crash barrier 111 is in contact with the inner side face of the crash barrier 111.

[0052] In this way, when constructing the concrete protective layer 13, it is only necessary to fill the area formed by the two baffles 14 and the crash barrier 111 with concrete and then level it with tools.

[0053] Furthermore, as Figure 10 , Figure 13 and Figure 14 shown, a washer 141 sleeved on the stud 1221 is arranged between the lock nut 1222 and the connecting steel plate 121 on the same side. The washer 141 and the baffle 14 on the same side are connected by a connecting piece 142. That is, the washer 141 sleeved on the stud 1221 of the locking assembly 122 for connecting the first connection end 1112 and the connecting steel plate 121 is connected to the baffle 14 straddling the first connection end 1112 through the connecting piece 142. The washer 141 sleeved on the stud 1221 of the locking assembly 122 for connecting the second connection end 1113 and the connecting steel plate 121 is connected to the baffle 14 straddling the second connection end 1113 through the connecting piece 142. The baffle 14, the washer 141 and the connecting piece 142 are of an integral structure and are made of plastic.

[0054] The reasons for such a design are as follows. First, it can provide side formwork for the construction of the concrete protective layer 13, thus facilitating the construction of the concrete protective layer 13. Second, as Figure 8 and Figure 9 shown, during assembly, under the clamping action of the connecting pieces 142 and the washers 141 on both sides, the connecting steel plate 121 can also be temporarily fixed to prevent the connecting steel plate 121 from tipping over. In this way, one person can complete the assembly, which is convenient for construction. Third, the presence of the washer 141 can play a role in preventing loosening of the locking assembly 122.

[0055] After the construction is completed, the baffle 14 can be removed. When removing the baffle 14, the connecting piece 142 needs to be cut off so that the baffle 14 and the connecting piece 142 are separated, or the baffle 14 can also not be removed. Although in an outdoor environment, the baffle 14 made of plastic will age and break, even so, since the concrete has hermetically wrapped the metal parts (the connecting steel plate 121 and the locking assembly 122), the problem of rusting of the connecting steel plate 121 and the locking assembly 122 will not occur.

[0056] Here, in order to enable the concrete as the protective layer to fully fill the area between the connecting piece 142 and the anti-collision wall 111, the connecting plate is preferably of an elongated structure. Preferably, the width of the connecting plate is preferably 5 mm - 8 mm.

[0057] Furthermore, as Figure 2 shown, a foundation base 112 perpendicular to the anti-collision wall 111 is provided at the lower end of the anti-collision wall 111, and the foundation base 112 is buried in the ground. The cross-section of the anti-collision wall 111 is in an inverted T-shaped structure. The anti-collision wall 111 and the foundation base 112 are of an integral structure and are made of reinforced concrete.

[0058] Furthermore, as Figure 1 and Figure 2 shown, the minimum distance M from the anti-collision pier to the steel pipe pole 2 should be greater than the height N of the anti-collision wall 111 exposed above the ground. In this way, even if the anti-collision wall 111 tilts or topples under the impact of a vehicle, it will not hit the steel pipe pole 2.

[0059] The assembly process of the anti-collision pier is as follows:

[0060] First, as Figure 5 shown, place the anti-collision wall 111 at the preset position and present a state of being connected end to end in sequence.

[0061] Second, as Figure 6 and Figure 7 shown, baffles 14 are respectively arranged on both sides of the joint, so that the baffles 14 straddle the anti-collision wall 111, and adjust the position of the baffles 14 on the anti-collision wall 111 until the washer 141 corresponds to the corresponding first mounting hole 1114.

[0062] Third, as Figure 8 and Figure 9 shown, insert the two connecting steel plates 121 from top to bottom between the washer 141 and the anti-collision wall 111 respectively, and align the second mounting holes of the connecting steel plates 121 with the corresponding first mounting holes 1114. Under the blocking effect of the washer 141 and the connecting piece 142, the connecting steel plates 121 can maintain a vertical state.

[0063] Fourth, asFigure 10 As shown, insert the stud 1221 and tighten the lock nut 1222 to complete the mechanical assembly.

[0064] Fifth, as Figure 11 shown, fill the space between the two baffles 14 with concrete and level it.

[0065] Sixth, repeat the operations in the second to fifth steps until the connection construction at all the connections of the crash barriers is completed.

The rest of the structure is the same as that of Embodiment 1.
