Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for illustrative purposes only.
Example (b):
referring to the attached drawings 1 and 2, the concrete pavement construction joint for the construction of the liquefied natural gas station comprises a dowel bar 1, a sleeve 2, a transverse supporting rib 3, a small bracket 4, an end baffle 5, an expansion joint plate 6 and a filler rod 7; the two small supports 4 are respectively arranged in two adjacent concrete foundations 8, the dowel bar 1 is arranged at the top of one small support 4 through the transverse supporting rib 3, and the sleeve 2 is arranged at the top of the other small support 4 through the transverse supporting rib 3; the axial direction of the dowel bar 1 is parallel to the road surface, and one end of the dowel bar is inserted into the sleeve 2; the two end baffles 5 are arranged in a construction joint 9 between the two concrete foundations 8, and the expansion joint plate 6 is arranged between the two end baffles 5; the insertion strip 7 is inserted into the construction joint 9, and the bottom surface of the insertion strip is in contact with the top surfaces of the end baffle 5 and the expansion joint plate 6. The length of the end baffle 5 is determined according to local climatic conditions, plate thickness, roadbed stable condition and experience. The length of the end baffle 5 is 4 to 5m, since the plate length is generally considered to be about 25 times the plate thickness.
When the construction is finished, a construction joint 9 is arranged when the construction is finished every day or the concrete pouring process is interrupted due to reasons. Before concrete pouring, a small support 4, a transverse supporting rib 3 and a dowel bar 1 are buried in a construction joint 9. The method is characterized in that round steel with the length of 500mm and the diameter of 28mm is basically selected as a dowel bar 1, and the dowel bar 1 is arranged in the thickness direction of a concrete roadbed 8 and is parallel to a pavement surface layer and the central line of an original road. The depth of the groove of the end baffle 5 is 1/2 which is equal to the thickness of the end baffle 5, so that the end baffle is not too deep, otherwise, the plate corner is easy to crack. The distance between the grooves is preferably 20-30 cm. After the front plate is initially set, the lower plate is pasted with an expansion joint plate 6 at a construction joint 9 before being poured, a small support 4 and a transverse supporting rib 3 are sequentially erected, the leaked dowel bar 1 is sleeved in the sleeve 2 with the inner wall coated with oil, and pouring is finished. After the concrete foundations 8 on the two sides of the construction joint 9 are finally cured, the embedded strips 7 made of non-metal materials are embedded until the embedded strips are level with the explosion-proof and non-firing concrete surface, and then construction is completed.
