specific Embodiment approach 1

[0025] Specific implementation mode one: as Figure 1-12 As shown, the urban road pavement rapid laying method described in this embodiment is realized according to the following steps:

[0026] Step 1, pre-preparing a large number of reinforced concrete blocks (regular hexagonal reinforced concrete blocks) as required;

[0027] Step two, leveling the roadbed;

[0028] Step 3: Lay the reinforced concrete blocks one by one on the leveled roadbed with lifting equipment (crane), and the upper surfaces of several reinforced concrete blocks are spliced ​​together to form the road surface.

[0029] Issues to be aware of when laying pavement with reinforced concrete blocks:

[0030] 1. Shape of reinforced concrete block

[0031] The shape of the reinforced concrete block is preferably a regular hexagon, because the road surface will bear a large force when the car brakes during driving. If a hexagonal reinforced concrete block is used, it can be guaranteed that the force borne by...

specific Embodiment approach 2

[0037] Specific implementation mode 2: In step 3 of this implementation mode, a gap of 5-20 mm is left between every two reinforced concrete blocks. When installing reinforced concrete blocks, a gap of 5-20 mm should be maintained between every two reinforced concrete blocks. This gap can compensate for the manufacturing error of the reinforced concrete blocks and reduce the constraints between the reinforced concrete blocks during maintenance. Force to facilitate the lifting of damaged reinforced concrete blocks. In addition, this gap also facilitates the infiltration of rainwater and reduces water accumulation on the road surface; it can also ensure that the road surface will not bulge due to thermal expansion and contraction. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0038] Specific implementation mode three: as Figure 1-12 As shown, at least three nuts 1 for lifting rings are preset on the main body 2 of the special reinforced concrete block for realizing the method described in the first embodiment described in this embodiment, and the nuts 1 for the at least three lifting rings are connected with the inside of the reinforced concrete block. The steel bars are welded together, and the two ends of the nut 1 for each suspension ring are exposed outside.

[0039] The present invention is to lay hexagonal reinforced concrete blocks produced by the factory according to certain rules on the already leveled roadbed. A plurality of hexagonal reinforced concrete blocks are combined to form a large plane, which is formed by continuing to extend and lay. The pavement of the entire road, such as image 3 shown. image 3 The side length and thickness of each regular hexagon can be appropriately changed according to the lifting capacity of the work...

Abstract

The invention relates to a method for fast paving urban road surfaces and a special reinforced concrete block, relating to the method for paving the road surface and the reinforced concrete block specially used in the method. The method aims at solving the problems of uneven road surface, easy frost boiling of the road and long pavage period of the cement road surface caused by the easy deformation of the existing asphalt road surface. The method includes the steps as follows: preparing a great amount of reinforced concrete blocks according to requirements in advance; leveling a subgrade; and paving the reinforced concrete blocks one after another on the leveled subgrade by hoisting equipment, and forming the road surface by splicing the upper surfaces of a plurality of reinforced concrete blocks. A main body of each reinforced concrete block is provided with at least three nuts for hoisting rings in advance, the three nuts for the hoisting rings are welded together with bar reinforcements in the reinforced concrete blocks, and the two end faces of each nut for the hoisting rings are respectively exposed outside. The method of the invention has the advantages of fastness, convenience and short pavage period. As the nuts for the hoisting rings are arranged in the reinforced concrete blocks in advance, the reinforced concrete blocks can be easily transported by the hoisting rings.

Description

technical field [0001] The invention relates to a pavement laying method and a special reinforced concrete block used in the method. Background technique [0002] At present, urban road pavements mainly include asphalt pavement and cement pavement. [0003] The road surface paved with asphalt mainly has the following two problems: 1. The smoothness of the road surface is not high enough: in summer, under the sun, the temperature of the road surface is high, and the asphalt is easy to soften. The deformation of the road surface leads to unevenness of the road surface, which affects the normal driving of the car, reduces the speed of the car, and reduces the capacity of the road. 2. The road is easy to muddy: In spring, when the north begins to thaw, due to the different degrees of thawing on the surface, the upper layer has softened, while the lower layer is still hard. Cars driving on it can easily damage the road surface, forming the so-called muddy road. [0004] Use the...
