The two guiding strips 300 correspond to the two sliders 200 in the first sliding grooves 101 one by one. Both ends of the guiding strips 300 are detachably connected to the corresponding sliders 200 on both sides. The upper end surfaces of the two guiding strips 300 are both inclined surfaces, and the inclined surfaces are inclined downward from the ends of the two guiding strips 300 close to each other to the ends away from each other;

[0037] A plurality of connecting bars 400 are provided between the two diversion bars 300. The connecting bars 400 are all placed coaxially with the diversion bars 300. Both ends of the connecting bars 400 are respectively slid in the first chutes 101 on both sides. The upper end surfaces of the connecting bars 400 are all in a horizontal plane shape, and the upper end surfaces of the connecting bars 400 are flush with the tops of the diversion bars 300.

[0038] At both ends of one side surface of the strip shaft 100 away from the connecting bar 400, clamping plates 500 are provided. The lower end surfaces of the clamping plates 500 are all lower than the lower end surface of the strip shaft 100. A pair of symmetrically placed driving units are provided on the strip shaft 100. The two driving units are respectively connected to the two clamping plates 500. The driving units are used to drive the clamping plates 500 to approach or move away from the strip shaft 100.

Moreover, the diversion bars 300 and the connecting bars 400 can be preset in multiple specifications with different lengths according to the common width specifications of the road surface.

[0040] When in use, the assembly steps of this device are as follows:

[0041] Step 1: Place the two strip shafts 100 on both sides of the road repair position respectively. The strip shafts 100 are all placed coaxially with the road surface, and both ends of the strip shafts 100 are placed on the road surfaces at both ends of the repair position along the axial direction of the road surface.

[0046] Through the above steps, the assembly process of the device is completed. Through the settings of the diversion bars 300 and multiple connecting bars 400, it is convenient for vehicles to pass effectively, and at the same time, it avoids rolling the concrete at the repaired part. The device is convenient to assemble during use, and the corresponding number of connecting bars 400 can be selectively placed according to the length of the repaired part along the road surface axis direction, improving the applicability of the device. At the same time, the settings of the two side clamping plates 500 and the driving unit realize the clamping and fixing of the device to the road surface, avoiding the device from being driven to slide out of position along the road surface when the vehicle passes, so as to ensure the effective shielding of the repaired part and prevent the repaired part from being crushed by the vehicle.

[0047] Preferably, the lowermost ends of the upper inclined surfaces of the diversion bars 300 are flush with the lower end surface of the strip shaft 100. During use, the two diversion bars 300 are respectively supported and placed on the road surfaces on both sides of the repaired part.

To solve the above problems, ventilation grooves 103 are provided on the strip shaft 100. The ventilation grooves 103 are all located directly below the first sliding grooves 101, and the ventilation grooves 103 penetrate through both sides of the strip shaft 100 along the axis direction of the connecting bars 400. The lower end surfaces of the connecting bars 400 are all higher than or equal to the upper end surfaces of the ventilation grooves 103.

[0049] A sealing pipe 902 is fixed on the upper end surface of any one of the ventilation grooves 103. The sealing pipe 902 is a hollow shell with both ends sealed, and the sealing pipe 902 is coaxially placed with the first sliding groove 101. A plurality of ventilation holes 9021 are provided on the peripheral wall of the sealing pipe 902 facing the other ventilation groove 103.

[0050] Preferably, the height difference between the upper end surface of the ventilation groove 103 and the road surface is 2 - 5 cm, so as to maintain the volatilization of the moisture in the concrete at the repaired part, contribute to the improvement of the solidification speed, and at the same time adjust the ventilation intensity and duration of the blower 900 according to the specific situation to ensure that the concrete can be properly ventilated and cooled, which is beneficial to the solidification process of the concrete at the repaired part.

[0051] In order to further improve the stability of the clamping of the device to the road surface, a limiting shaft 501 is fixed on one side of the clamping plate 500 close to the strip shaft 100, and the limiting shafts 501 are all placed coaxially with the connecting strip 400; before the clamping plate 500 fits and clamps both sides of the road surface, corresponding holes are first drilled on the side surface of the road surface by equipment such as an electric drill. When the clamping plate 500 clamps the side wall of the road surface, the limiting shafts 501 are all inserted into the corresponding holes, further improving the stability of the clamping of the device to the road surface and preventing the device from sliding out of position along the axis direction of the road surface.
