Description

Technical Field

[0001] The invention relates to the technical field of polymer grouting repair, and in particular to a polymer composite grouting method, system, equipment and medium for repairing road water damage. Background Art

[0002] With the rapid development of my country's economy, road traffic has also grown rapidly. At present, a systematic highway network has been formed. However, with the continuous advancement of road construction, the tests and challenges faced by the road maintenance field have also followed. Among them, water damage to roads is one of the important causes of road damage, mainly manifested in pumping, peeling, potholes and looseness and the resulting insufficient bearing capacity. When cracks appear on the road surface, water will penetrate into the pavement structure layer. Under the combined effect of load and environment, water will further scour the various structural layers of the road, resulting in poor interlayer contact in the pavement structure, and interlayer water accumulation will occur, thus affecting the service life of the road surface. On the other hand, if water continues to infiltrate, it will further erode the roadbed and erode the roadbed soil, thereby weakening the roadbed bearing capacity. Therefore, it is particularly important to propose corresponding solutions and repair measures for road water damage.

[0003] Polymer grouting technology is a rapid foundation reinforcement technology developed in the 1970s. This technology uses grouting equipment to inject two-component polymer materials into designated locations, rapidly generating expandable polymers through chemical reactions. During the reaction, the polymer rapidly expands to generate a relatively solid foam-like solid and releases a higher expansion force, thereby filling the gaps in the structure, compacting the loose structure, and discharging excess water to repair structural gaps and diseases, prevent seepage and plug leaks, etc.; due to the characteristics of polymer materials such as light weight, fast reaction, good durability, and excellent thermal insulation and anti-seepage properties, polymer materials are widely used in anti-seepage, reinforcement and repair projects in transportation fields such as roads and railways. At present, there are existing technologies that use expanded polymers for lifting high-speed rail ballastless tracks (for example: CN106012697A, CN103215863A), roadbed and pavement repair (for example: CN101261263B, CN101261264B), etc. The above existing technologies all use expanded polymer grouting materials, and use their rapid reaction and expansion properties to fill and repair road surface defects such as voids and mud pumping or compact the soil. However, the current single grouting method cannot comprehensively treat the water damage to the road surface, especially the interlayer separation and water accumulation disease of the road surface structure layer. The traditional grouting method is difficult to effectively prevent and control it. The loose roadbed soil causes insufficient road surface bearing capacity and cannot be treated by traditional expanded polymers. This is mainly because the expanded polymer reacts quickly and has expansion properties, so it cannot penetrate into the roadbed soil to consolidate the soil and improve the roadbed self-stress. These water damages will seriously affect highway safety. Summary of the invention

[0045] The following specifically illustrates the implementation mode of the present invention in conjunction with the accompanying drawings. The embodiments are provided for illustrative purposes only and cannot be understood as limiting the present invention. The accompanying drawings are provided for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention, because many changes can be made to the present invention without departing from the spirit and scope of the present invention.

[0046] refer to Figure 1 The embodiment of the present invention provides a polymer composite grouting method for repairing water damage on a road surface, such as Figure 1 As shown, the method comprises the following steps:

[0047] S1. Use ground penetrating radar and drop weight deflectometer to detect road surface damage and obtain the road surface damage type, location and degree.

[0048] In one embodiment, the step of using a ground penetrating radar and a drop weight deflectometer to detect road surface defects and obtaining road surface defect detection results includes:

[0049] Using ground penetrating radar to detect road surface damage and determine the road surface damage type and road surface damage location; in this embodiment, the road surface damage type includes loose water-rich roadbed damage and water accumulation between interface layers;

[0050] A drop weight deflectometer is used to detect the pavement damage location to obtain a deflection basin index, and the pavement damage degree corresponding to different pavement damage types is determined based on the deflection basin index.

[0051] Specifically, this embodiment first uses ground penetrating radar to detect road surface diseases, obtains radar maps of the internal structure of the road surface, and determines the road surface disease type and road surface disease location based on the radar maps. Table 1 is a ground penetrating radar soil disease type assessment table:

[0052] Table 1

[0053]

[0054] Then, in this embodiment, at the locations of different types of defects detected, the drop weight deflectometer is used to accurately determine the interlayer damage state of the pavement and the bearing capacity of the roadbed. The position distribution of each sensor in the drop weight deflectometer is shown in Table 2. The deflection basin index is calculated using sensors with different displacements, so that the degree of pavement defects corresponding to different types of pavement defects can be determined by the deflection basin index. Table 2 is shown below:

[0055] Table 2

[0056]

[0057] It should be noted that D1~D9 represent the 1st to 9th sensors, and the values ​​corresponding to D1~D9 represent the ground deformation tested by each sensor after the drop weight deflectometer applies load to the ground; among them, the base damage index BDI is the difference between the reading of sensor D3 and the reading of sensor D5, that is, BDI=D3-D5; the roadbed damage index is the value corresponding to sensor D9; the base index BDI and the roadbed damage index D9 respectively characterize the defect conditions of the base and the subgrade.

[0058] S2. Determine a grouting scheme based on the type of pavement damage and the degree of pavement damage; the grouting scheme includes a grouting repair method, hole layout and grouting amount; the grouting repair method includes an expandable polymer grouting repair method and a permeation grouting repair method.

[0059] In one embodiment, the step of determining the grouting scheme according to the pavement damage type and the pavement damage degree includes:

[0060] If the pavement damage type is water accumulation between interface layers, the expansion polymer grouting repair method is selected;

[0061] If the pavement damage type is loose and water-rich roadbed damage, the penetration grouting repair method is selected.

[0062] In one embodiment, Figure 2 As shown, the expansive polymer grouting repair method specifically includes:

[0063] Determine the expandable polymer, and obtain the diffusion radius of the expandable polymer according to the preset density of the expandable polymer after the reaction is complete; in this embodiment, the expandable polymer includes an expandable polyurethane material; the expandable polyurethane material is a two-component material;

[0064] Obtaining a grouting amount according to the preset density and diffusion radius of the expanded polymer after the reaction is complete;

[0065] According to the diffusion radius of the expanded polymer and the degree of the pavement disease, the horizontal spacing of the grouting holes is obtained, and the holes are arranged according to the horizontal spacing of the grouting holes to drill the grouting holes;

[0066] A sealing grouting pipe and a feeding pipe are placed in each grouting hole, and an expandable polymer is injected into the sealing grouting pipe to seal the grouting hole after the expandable polyurethane material reacts completely, so that the grouting hole is in a closed state;

[0067] The expandable polymer is transported to the injection gun nozzle. After the two-component materials of the expandable polyurethane are mixed at the injection gun nozzle, the expandable polymer material is transported to the pavement disease location, that is, the interface location of the road base and the semi-rigid base using a feed pipe. Due to the rapid reaction and expansion characteristics of the expandable polymer, the slurry of the expandable polymer will diffuse and fill along the interface area, and a chemical reaction will occur. The material changes from liquid to solid, and the volume expands rapidly. The accumulated water between the road base and the semi-rigid base is squeezed out from the remaining grouting holes, and the soil around the interface is compacted, and the interface between the semi-rigid base and the road base is bonded to restore the interface to a bonding state.

[0068] It should be noted that the current calculation method for the diffusion distance grouting of expandable polymers does not take into account the type and degree of the disease. It is mostly based on experience. Different types and degrees of diseases usually use the same grouting calculation method, which has a large error. If the calculated diffusion radius is large, the grouting volume will be insufficient, making it difficult to effectively treat the disease. If the calculated diffusion radius is small, the grouting volume will be too large, which will lift and damage the road surface and cause material waste. At present, there is still a lack of a calculation method for the diffusion radius of expandable polymer grouting specifically for interface detachment and water accumulation diseases, and there is no calculation method for the density of the slurry after complete reaction. The density of the polymer after complete reaction has a significant impact on the repair effect of the polymer.

[0069] In this embodiment, the diffusion radius R of the expanded polymer is 1 The calculation formula is:

[0070]

[0071] In the formula, R 1 represents the diffusion radius of the expandable polymer; α represents the diffusion radius coefficient of the expandable polymer, and in this embodiment, α∈[0.5, 0.75] is preferably set; P represents the grouting pressure of the expandable polymer, and in this embodiment, P is preferably set to 1; ρ 1 Indicates the density of the preset expanded polymer after the reaction is complete.

[0072] It should be noted that, through experiments, it was found that when the polymer density is 0.1-0.2g / cm 3 When the polymer density exceeds 0.2g / cm 3 When the bonding strength is not less than 1.6 MPa, the density of the expanded polymer after the reaction is complete is preset according to the bonding strength between the polymer and the concrete. When the interlayer state of the pavement is medium, the polymer density is designed to be 0.1-0.2 g / cm 3 When the interlayer condition of the pavement is serious, the polymer density is designed to be 0.2g / cm 3 above.

[0073] The calculation formula of the grouting amount is:

[0074]

[0075] Where, M represents the injection volume of the expansive polymer; R 1 represents the diffusion radius of the expanded polymer; ρ 1 Indicates the density of the preset expanded polymer after the reaction is complete.

[0076] Since polymers are different from cement-based grouting materials, they will expand and their density will change during reaction. The mechanical properties, expansion properties and impermeability properties of polymers are mainly affected by the density of polymers. Only by controlling the density of polymers can the repair effect be controlled. Therefore, this embodiment calculates the slurry density of the expandable polymer, so that the grouting amount can be obtained more accurately. The existing technology only calculates the volume through length, porosity and radius, which is not suitable for expandable polymers.

[0077] The horizontal spacing L of the grouting holes 1 The calculation formula is:

[0078] L 1 =R 1

[0079] Wherein, represents the degree of pavement disease corresponding to the water accumulation disease between interface layers. In this embodiment, when the interlayer detachment and water accumulation are judged to be moderate according to the ground penetrating radar map, β∈[0.9, 1.1]; when the interlayer detachment and water accumulation are judged to be severe according to the ground penetrating radar map, β∈[0.7, 0.9].

[0080] In one embodiment, Figure 3 As shown, the penetration grouting repair method specifically includes:

[0081] Determine a permeable polymer, and obtain a diffusion radius of the permeable polymer according to the injection pressure of the permeable polymer and the degree of the pavement disease; the permeable polymer includes a permeable polyurethane;

[0082] Arranging holes according to the diffusion radius of the permeable polymer, and drilling grouting holes according to a preset grouting hole depth rule;

[0083] A sealing grouting pipe and a feeding pipe are placed in each grouting hole, and a permeable polymer is injected into the sealing grouting pipe to block the grouting hole opening, so that the grouting hole is in a closed state;

[0084] After the permeable polymer is transported to the injection gun nozzle for mixing, it is transported to the pavement defect location through a feed pipe, so that the permeable polymer can penetrate and diffuse under pressure to fill the pores of the pavement material and re-bond the loose pavement material into a consolidated body.

[0085] Specifically, this embodiment first obtains the base damage index BDI according to Table 2 above, and then determines the degree of pavement damage of loose and water-rich roadbed damage according to the base damage index BDI. The specific determination process is as follows:

[0086] When the base damage index BDI ≥ 50, the base is judged to be loose and the bearing capacity is seriously insufficient;

[0087] When the base damage index BDI is within the range of 30-50, the base is judged to be loose and the bearing capacity is insufficient;

[0088] When the base damage index BDI is within the range of 20-30, the base is judged to be damaged and the bearing capacity is reduced.

[0089] When the reading of sensor D9 is ≥3, it is judged that the roadbed is seriously damaged and the strength is seriously insufficient;

[0090] When the reading of sensor D9 is within the range of 2 to 3, it is judged that the roadbed is damaged and the strength is insufficient;

[0091] When the reading of sensor D9 is within the range of 1 to 2, it is judged that the roadbed is slightly damaged.

[0092] Then, according to the degree of road surface damage caused by loose and water-rich roadbed, this embodiment uses the low viscosity and strong bonding characteristics of the permeable polymer to perform grouting repair on the interlayer state, and obtains the diffusion radius of the permeable polymer according to the grouting pressure of the permeable polymer and the degree of road surface damage. The diffusion radius R of the permeable polymer is 2 The calculation formula is:

[0093]

[0094] In the formula, R 2 represents the diffusion radius of the permeable polymer; δ represents the diffusion radius coefficient of the permeable polymer. In this embodiment, δ∈[0.5, 0.75] is set; P′ represents the grouting pressure of the permeable polymer, which is 1MPa when grouting the semi-rigid base and 0.6MPa when grouting the roadbed; ε represents the pavement structure damage coefficient. When calculating the grouting radius of the semi-rigid base, When calculating the grouting radius of the roadbed,

[0095] The grouting holes are arranged according to the diffusion radius of the permeable polymer, and then the grouting holes are drilled; when repairing the semi-rigid base, the depth of the grouting holes is 0.1m from the bottom of the semi-rigid base, and when repairing the roadbed disease, the depth of the grouting holes is 0.1m from the bottom of the roadbed; a sealing grouting pipe and a feed pipe are placed in each grouting hole, and the sealing grouting pipe is grouted. After grouting, the sealing grouting pipe will block the grouting hole mouth, so that the grouting hole is in a closed state;

[0096] Finally, the infiltration grouting is started. The two-component material of the infiltration type polyurethane is transported to the injection gun nozzle. After the two materials are mixed at the injection gun nozzle, they are transported to the location of the pavement disease through the feed pipe. Under the action of pressure, the slurry will penetrate and diffuse to fill the pores inside the pavement material, and re-bond the loose pavement material into a consolidated body to improve the strength of the original pavement material, thereby restoring the bearing capacity of the pavement structure.

[0097] S3. According to the grouting scheme, grouting repair is performed at the corresponding pavement disease location.

[0098] The embodiment of the present invention provides a polymer composite grouting method for repairing road water damage. The method determines the type, location, and severity of road damage through ground penetrating radar and drop weight deflectometer. At the same time, based on different grouting repair methods, targeted road damage is treated, and corresponding hole layout methods and grouting amounts are set according to different road damage degrees, which can greatly reduce the damage to the road surface in the later stage, solve the problems of cracks, interlayer water accumulation, and roadbed weakening caused by road water erosion, improve the road surface bearing capacity, and extend the service life of the old road. Compared with the prior art, this method has the advantages of convenient construction, high efficiency, safety and reliability, significantly improves the bearing capacity and stability of the roadbed structure in the diseased area, and brings considerable economic and social benefits.
