Problems solved by technology

For the construction of white pavement (cement concrete pavement), it is necessary to place formwork in the road bed and configure steel mesh in it, and also to set longitudinal joints, transverse joints, construction joints between the design plates, and place tie rods and dowel bars. Concrete also needs a long curing period, so the construction period of traditional road structures is longer
[0005] 2) The road construction is affected by the ambient temperature and the usable days are short
This limits the range of months and the total number of days that the road can be constructed in a year, which restricts the road construction plan
[0007] 3) Short service life of road structure
[0009] In the bidding process of construction projects, the weight of the low cost index of the project is often unilaterally increased, resulting in insufficient capital investment during the construction period of the project. Together with the short construction period, it becomes the original defect that affects the quality of the road, making quality assurance more difficult and causing road service life. shorten

Embodiment 1

[0035] 1) Firstly, the truss structure is made. Two transverse diaphragms and two longitudinal diaphragms are poured with epoxy resin mixed mortar to form a truss space body and sit on the bottom plate. The inclination angle between the two transverse diaphragms and the bottom plate is an acute angle. The inclination angle between the two longitudinal septum plates and the bottom plate is an obtuse angle;

[0036] 2) Combine the prepared quadrilateral truss space body in the form of two-way staggered joints, such as figure 1 , 3 As shown, every four adjacent space bodies can form an hourglass-shaped cavity, and epoxy resin mixed mortar is poured into the cavity to form a truss column 4; the column shape is as follows Figure 5 , 6 shown.

[0037] 3) After the truss space body 1 is combined, it sits on the bottom plate 3, where the bottom plate 3 is composed of a geogrid embedded in crushed stones and filled with epoxy resin mixed mortar to form a composite bottom plate loca...

Embodiment 2

[0045] 1) First of all, the truss structure is made, which is formed by pouring epoxy resin mixed mortar to form three transverse diaphragms and three longitudinal diaphragms to form a truss space body and sit on the bottom plate. The inclination angle between the three transverse diaphragms and the bottom plate is an acute angle. The inclination angle between the three longitudinal septum plates and the bottom plate is an obtuse angle;

[0046] 2) Combine the prepared hexagonal truss space body 1 in a honeycomb shape, and every three adjacent space bodies can form an hourglass-shaped cavity, and pour epoxy resin mixed mortar into the cavity to form the truss column 4;

[0047] 3) After the truss space body 1 is combined, it sits on the bottom plate 3, where the bottom plate 3 is a composite bottom plate composed of geogrid 5 embedded in crushed stones and filled with epoxy resin mixed mortar;

[0048] 4) Pour the inorganic mixture into the truss space to form a complete road...

Embodiment 3

[0051] 1) if Figure 7 As shown, firstly, the truss structure is made. Two transverse diaphragms and two longitudinal diaphragms are poured with epoxy resin mixed mortar to form a truss space body 1 and sit on the bottom plate 3. The inclination angle between the two transverse diaphragms and the bottom plate is an acute angle, and the inclination angle between the two longitudinal septums and the bottom plate is an obtuse angle; Image 6 As shown, the upper end faces of the diaphragm and the longitudinal diaphragm are Y-shaped, which can relieve stress concentration and block reflection cracks.

[0052] 2) Combine the prepared quadrilateral truss space bodies in the form of two-way staggered joints, in which every four adjacent space bodies can form an hourglass-shaped cavity such as Figure 5 As shown, the epoxy resin mixed mortar is poured into the cavity to form the truss column 4;

[0053] 3) After the truss space body 1 is combined, it sits on the bottom plate 3, where...

Abstract

The invention relates to a method for splicing a durable road structure by brickworks formed by organic mixture trusses. The method is characterized by comprising the specific steps of: firstly, manufacturing truss structures; combining manufactured truss space bodies in a bidirectional break joint manner; putting the combined manufactured truss space bodies on a seat plate; respectively pouring an inorganic mixture into the manufactured truss space bodies to form an integral road base layer structure; and paving a conventional abrasion layer on the road base layer structure. The method disclosed by the invention adopts the truss formed by an organic mixture and the inorganic mixture is filled into the truss to form the brickworks; the brickworks are spliced into a durable road structure so that the aims of shortening a construction period and prolonging the usable time period of construction can be realized and the road construction working period can be effectively shortened; and the structure of a truss bridge sheet sufficiently utilizes the characteristic of the stability of a triangle so that the service life of a road can be prolonged in the use process.

Description

technical field [0001] The invention relates to a method for assembling the masonry made of organic mixture truss into a durable road structure, which is to fill the interior of the organic mixture truss with inorganic mixture to form a masonry, and then complete the assembled durable road structure; Urban roads, port roads, oil field roads, emergency roads. Background technique [0002] The current road construction is restricted by the following conditions, so there are the following problems: [0003] 1) Road construction is restricted by the curing period of road construction materials, and the construction period is long [0004] The municipal road structure is mainly divided into two types: black pavement and white pavement. The construction methods are all completed layer by layer at the bottom of the road bed. For example, the construction process of black pavement is a road formed by paving, rolling and curing of various layers of road materials. For the construc...
