[0039] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not used to limit the present application.

[0040] Please refer to Figures 1 to 3 , the present application will be described in detail. The high-quality construction method of concrete road engineering, comprising:

[0041] The construction range is demarcated and the road base is constructed, the base is reinforced to meet the requirement of the bearing capacity of the base.

[0042] A plurality of concrete base blocks 1 are laid on the base in sequence, and the base blocks 1 are positioned on the base.

[0043] The reinforcing bars 3 are connected between the adjacent two base blocks 1, and the filler blocks 2 are clamped between the adjacent two base blocks 1.

[0044] The concrete is poured at the reinforcing bars 3, and after the concrete is solidified, the base blocks 1 and the filler blocks 2 together form a surface layer, and the surface layer is trimmed and post-processed.

[0045] The high-quality construction method of concrete road engineering provided by the present application has the beneficial effects that: compared with the prior art, in the high-quality construction method of concrete road engineering of the present application, the construction range is first demarcated and the road base is constructed, in order to meet the requirement of the base, the base needs to be reinforced, a plurality of concrete base blocks 1 are laid on the base, and the positioning of the base blocks 1 and the base is completed. The reinforcing bars 3 are connected between the adjacent base blocks 1, and the filler blocks 2 are clamped between the adjacent two base blocks 1. The concrete is poured at the reinforcing bars 3, and after the concrete is solidified, the base blocks 1 and the filler blocks 2 together form a surface layer, and the surface layer is trimmed and post-processed.

[0046] In the present application, by laying and positioning the base blocks 1 on the base, and by connecting the reinforcing bars 3 and clamping the filler blocks 2, the construction steps are simplified, the construction efficiency is improved, the generation of cracks and other problems is reduced, and subsequent maintenance and processing are facilitated.

[0047] Road is a basic infrastructure for various trackless vehicles and pedestrians to pass through in terms of word meaning, and is classified into highway, urban road, rural road, mine road, forestry road, test road, competition road, automobile test road, workshop passage and school road according to use characteristics. Road traffic has long been regarded as a prerequisite for economic development, greatly promoting the development of regional economy. Through the function of road traffic, the rational allocation of regional means of production is realized, various resources in the region are integrated, the flow of materials, information, talents and funds between regions is promoted, the adjustment of industrial structure in the region is promoted, and the development of transportation will ultimately promote the development of regional economy. The existing concrete pavement generally uses the method of pouring into shape.

[0048] In some embodiments of the high-quality construction method of concrete road engineering provided in the application, the construction range is demarcated and a road base is constructed.

[0049] The geological conditions of the current area to be constructed are measured to determine the hardness, looseness and impurity conditions of the stratum.

[0050] In the past, the roads in China, especially the expressways, were often built on soft soil foundations. Due to the poor construction technology or low quality during construction, the roads built often have the phenomenon of road surface settlement over time, which finally leads to road surface collapse. In the construction method of road reconstruction for reinforcing the soft soil foundation soil body by means of cement mixing, a plurality of micro holes are opened in the area where the road surface collapse occurs, and the soft soil foundation soil body under the road base is reinforced by means of the cement mixing equipment through the micro holes. The construction method has the advantages of not having to damage the road surface in a large area, not having to excavate the road base in a large area, and low construction cost. The construction method has the disadvantage of limited reinforcement effect on the soft soil foundation soil body, and the reconstructed road surface still collapses.

[0051] After the existing road is damaged, the area that needs to be repaired is often large, which leads to high repair cost and affects normal vehicle driving.

[0052] Based on the above reasons, the application provides a new road construction method, which can greatly improve the construction efficiency of the road, more importantly, reduce the maintenance cost of the road, and also can quickly complete the paving of the road for uneven road surfaces, and has strong applicability.

[0053] In some embodiments of the high-quality construction method of concrete road engineering provided in the application, before the construction range is demarcated and the road base is constructed, the method further includes:

[0054] If the stratum hardness is low, the stratum is treated by ramming, and the elevation after ramming meets the construction requirements.

[0055] If the stratum hardness is higher, the roadbed trench is excavated.

[0056] The bearing capacity of the base layer is the key to ensure the stability of the entire road shape and service life, based on the above reasons, the compaction treatment needs to be carried out after the roadbed trench is excavated. Specifically in the implementation process, first of all, according to the paving range of the road, the line is drawn, after the line is drawn, according to the current pavement stratum structure, the pavement excavation or direct compaction treatment is selected.

[0057] It should be pointed out that if the current stratum is loose, that is, the hardness is low, the ground needs to be compacted by the compactor, and the subsidence degree of the compacted stratum needs to meet the preset requirements, the final purpose is to ensure that there is enough roadbed trench to place the concrete base block 1 and the subsequent material paving.

[0058] In some embodiments of the high-quality construction method for concrete road engineering provided in the application, the reinforcing treatment of the base layer makes the bearing capacity of the base layer meet the requirements, including:

[0059] Selecting gravel of a corresponding specification, inserting the gravel into the base layer at a set depth one by one, and improving the bearing capacity of the base layer through the gravel; or

[0060] Uniformly spraying a solidifying agent on the base layer; when the bearing capacity requirement of the base layer is high, the solidifying agent is sprayed and the soil is backfilled in turn for multiple times.

[0061] When the roadbed trench is processed, if a plurality of concrete base blocks 1 are directly laid on it, due to the low bearing capacity of the base layer, the entire pavement is prone to collapse under the continuous extrusion of vehicles and the like on the pavement, and the related structure will be damaged. In view of the above situation, the formed base layer needs to be reinforced to improve the structural stability of the entire pavement.

[0062] Therefore, a plurality of base layer reinforcing methods are provided in the application. The first method is to lay gravel on the base layer after the base layer is processed. It should be pointed out that the gravel for reinforcing the base layer is not an ordinary structure. In order to be able to strengthen the base layer, the structure of the gravel used in the application is special, which is long strip or plate structure, that is, the surface area of the gravel is large but the cross-sectional area is small. In the laying process, the gravel needs to be preliminarily positioned first, so that the gravel can be inserted into the base layer in the vertical direction. When compacting, the gravel can be inserted more into the inside of the base layer, and finally the reinforcing treatment is completed.

[0063] For the scenario of less commuting pressure after the construction, a solidifying agent can be sprayed on the base layer, which can improve the hardness of the entire base layer. In order to improve the injection amount of the solidifying agent, multiple spraying can be used, that is, a deep excavation is needed. After spraying the solidifying agent and solidifying the solidifying agent, the soil is backfilled, and after backfilling, the soil is compacted. After compaction, the solidifying agent is sprayed again, and so on. Until the integrated bearing capacity meets the requirements.

[0064] In some embodiments of the high-quality construction method of the concrete road engineering provided in the application, sequentially laying a plurality of concrete base blocks 1 on the base layer comprises:

[0065] The base block 1 is positioned on the base layer, and the connection force between the base block 1 and the base layer meets the requirements.

[0066] After the base layer treatment is completed, the laying of the concrete base block 1 is needed. It should be noted that the concrete base block 1 is prefabricated in the factory, that is, the factory needs to process the concrete base block 1 that meets the requirements in advance according to the requirements of road construction and the specifications set. The number of concrete base blocks 1 is multiple, and the multiple concrete base blocks 1 need to be laid in the corresponding order.

[0067] It should be noted that although the treatment of the base layer can ensure that the base layer has sufficient bearing capacity, that is, it can ensure that the base layer has less deformation under the action of the upper pressure and a series of problems, but if the road itself has a certain slope, or due to the low connection force between the concrete base block 1 and the base layer, the relative displacement occurs between the base block 1 and the base layer, which eventually makes the entire road surface uneven.

[0068] Therefore, after the base layer is reinforced, an adhesive can be sprayed on the corresponding position of the base layer, or an adhesive can be sprayed on the bottom surface of the base block 1, so as to improve the stability between the base block 1 and the base layer and avoid the problem of displacement.

[0069] In some embodiments of the high-quality construction method of the concrete road engineering provided in the application, positioning the base block 1 on the base layer comprises:

[0070] The positioning rod is inserted into the base layer until the base block 1 abuts against the base layer, so as to complete the positioning of the base block 1.

[0071] After the base layer is processed, the base block 1 needs to be laid thereon, and for some important occasions or occasions with heavy commuting pressure, the relative stability between the base block 1 and the base layer is the key to ensure the stability of the entire road shape. And in the actual application process, the vehicle not only has a vertical downward pressure on the base block 1, but also has an acute angle force with the road surface, which may cause the displacement between the base block 1 and the base layer.

[0072] Based on the above reasons, in order to further complete the positioning of the base block 1, a positioning rod is installed on each base block 1 in the present application, and for further description, a connecting plate is fixed at the top end of each positioning rod, which can be fixed on the base block 1 by expansion bolts. In some special occasions, a bolt rod can be reserved at a specific position of the base block 1, and the bolt rod penetrates the connecting plate and finally completes the positioning of the positioning rod through the bolt.

[0073] In the actual installation process, the positioning rod needs to be preliminarily positioned on the base layer, and then the base block 1 is gradually impacted by a compactor or the like. In the process of impacting the base block 1, the positioning needle will gradually insert into the base layer, and when the base block 1 abuts against the base layer, the final positioning of the base block 1 can be completed.

[0074] In some embodiments of the high-quality construction method of the concrete road engineering provided in the present application, please refer to Figure 2 The connecting reinforcing rib 3 between the adjacent two base blocks 1 comprises:

[0075] The base blocks 1 are sequentially laid on the base layer in order, and the distance between the adjacent base blocks 1 is ensured to be the same.

[0076] The connecting points are arranged at the corners of the base block 1, and the reinforcing rib 3 is bolted between the two connecting points.

[0077] There is a certain distance between the adjacent base blocks 1. In order to improve the structural stability of the entire road, that is, to improve the service life of the road and avoid a series of problems such as cracks in the road surface, a reinforcing net is arranged in the concrete during the pouring of the concrete, and the reinforcing net is used to prolong the stability of the entire road.

[0078] In the present application, in order to improve the structural bearing capacity of the road and improve the relative position stability between the adjacent base blocks 1, the reinforcing rib 3 needs to be connected and fixed between the adjacent base blocks 1. That is, after the preliminary positioning of each base block 1, the reinforcing rib 3 needs to be connected between the adjacent base blocks 1, so that the plurality of base blocks 1 become a relatively stable whole.

[0079] In order to make the description more detailed, firstly, connecting rings are reserved on the corners of the base blocks 1, or expansion bolts can be installed on the sides of the base blocks 1. The two connecting rings or expansion bolts are connected through the reinforcing bars 3 between the two base blocks 1, and the reinforcing bars 3 need to be kept in a tensioned state. Through the above setting, the clamping and fixing between the multiple base blocks 1 are finally completed.

[0080] In some embodiments of the high-quality construction method of the concrete road engineering provided in the application, please refer to Figure 3 Arc-shaped grooves are formed on the two sides of the filling block 2, the base block 1 is matched with the arc-shaped grooves, and the filling block 2 can swing a certain angle relative to the base block 1 through the arc-shaped grooves.

[0081] The base blocks 1 in the application are spaced apart at a certain distance. If the base blocks 1 abut against each other, the construction difficulty and cost will undoubtedly increase, because the number of positioning needles needed for construction will increase. More importantly, if the base blocks 1 abut against each other, when the external environment temperature changes, the base blocks 1 may be warped or have gaps.

[0082] Therefore, the filling block 2 is arranged between the two adjacent base blocks 1 in the application, and the filling block 2 is positioned between the two base blocks 1. More importantly, the filling block 2 cannot be pulled out from between the two base blocks 1, and the ultimate purpose is to ensure the stability of the position between the base block 1 and the filling block 2.

[0083] In order to make the description more detailed, arc-shaped grooves are arranged on the two sides of the filling block 2, and the sides of the base block 1 are provided with protrusions matched with the arc-shaped grooves. The filling block 2 is positioned between the two adjacent base blocks 1 through the arc-shaped grooves on the two sides.

[0084] In order to fill the gap between the base block 1 and the filling block 2 after the base block 1 swings, the concrete or other filling agent 4 is injected between the two.

[0085] In some embodiments of the high-quality construction method of the concrete road engineering provided in the application, please refer to Figure 3 And the filling block 2 is clamped between the two adjacent base blocks 1, which comprises:

[0086] The positioning rod is vertically inserted into the base layer, and the base block 1 is ensured to be laid according to the undulating slope of the base layer.

[0087] The fixing agent is sprayed between the base block 1 and the filling block 2, and the connecting force between the base block 1 and the filling block 2 is improved through the fixing agent.

[0088] The split structure between the base block 1 and the filling block 2 in the application has the advantages of facilitating installation and maintenance, and reducing the cost and improving the efficiency of road maintenance.

[0089] More importantly, since the filling block 2 can swing at a certain angle relative to the base block 1, based on the above characteristics, when the road undulates, the base block 1 is first positioned along the road length, the positioning needle on the base block 1 is always vertically inserted into the base layer, and at this time, the spatial angle of the base block 1 will also be deflected with the undulation of the base layer. After the positions of the plurality of base blocks 1 are determined, the filling block 2 is inserted between the two adjacent base blocks 1 to complete the paving.

[0090] In order to ensure the reliable connection between the base block 1 and the filling block 2, it is necessary to spray a fixing agent between the base block 1 and the filling block 2. Specifically, a certain amount of fixing agent can be sprayed on the side surface of the filling block 2 and the side surface of the base block 1 before the filling block 2 is installed, and then the filling block 2 is inserted. After the fixing agent is solidified, the base block 1 and the filling block 2 can be in a relatively integrated stable structure.

[0091] In some embodiments of the high-quality construction method of the concrete road engineering provided in the application, the concrete pouring at the reinforcing rib 3 comprises:

[0092] The reinforcing rib 3 is connected at the corner of the base block 1, and the concrete is poured outside the reinforcing rib 3.

[0093] The concrete is ensured to fill the space surrounded by the filling block 2 and the base block 1.

[0094] For further illustration, the base block 1 is approximately a cuboid structure, and the reinforcing rib 3 is connected between the opposite corners of the two base blocks 1. Taking four base blocks 1 as an example, the four base blocks 1 are spaced from each other, thereby forming a cross-shaped groove in the middle part. The cross-shaped groove includes a middle cavity and four connecting cavities. The reinforcing rib 3 is connected in the middle cavity, and at this time, the two reinforcing ribs 3 are arranged vertically. The ends of the reinforcing rib 3 are connected to the opposite base blocks 1, and the reinforcing rib 3 is arranged in the middle cavity. The filling block 2 is inserted into the connecting cavity, and the middle cavity is filled with concrete.

[0095] The above is only a preferred embodiment of the application, and is not used to limit the application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
