Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a green and environmentally friendly installation method of a spliced ​​slope protection. Background Art

[0002] Slope protection is a general term for various paving and planting done on the slope surface to prevent the slope from being eroded. In civil engineering, slope protection is an engineering measure taken to protect soil and rock from natural factors such as rain erosion, wind erosion, and wave impact. There are many forms of slope protection, among which spliced ​​slope protection is one of the most widely used in recent years. Spliced ​​slope protection is a slope protection structure with a special design and construction method. It forms an overall stable slope protection system by splicing and combining multiple independent slope protection units or modules. This slope protection method is widely used in water conservancy, transportation, urban construction and other fields, and is particularly suitable for areas with complex terrain and difficult construction.

[0003] Chinese Patent Publication No.: CN106223350B, discloses a concrete frame ecological slope protection module, slope protection and its installation method, wherein the installation method of the concrete frame ecological slope protection is characterized in that: during installation, the concrete frame ecological slope protection modules are arranged on the slope surface, the adjacent concrete frame ecological slope protection modules are docked and positioned by means of columnar male locks and columnar female locks, and the two modules are quickly overlapped and fixed by means of screw holes and screws to ensure the connection and fixation between the two modules, and then the anchor rods are installed into the slope surface body through the anchor rod holes on the bottom surface, thereby ensuring the connection and fixation of each module with the slope surface. It can be seen that the above technical solution lacks the necessary pretreatment means for the supporting soil layer of the slope protection, resulting in the risk of partial settlement of the slope protection after the construction is completed. Summary of the invention

[0004] To this end, the present invention provides a green and environmentally friendly installation method for a spliced ​​slope protection, which is used to overcome the problem in the prior art that the slope protection has the risk of settlement after construction is completed due to the lack of necessary detection and treatment of the slope protection supporting soil layer.

[0005] To achieve the above object, the present invention provides a green and environmentally friendly installation method of a spliced ​​slope protection, comprising:

[0006] Step S1, surveying the river channel slope protection to be constructed to obtain slope protection soil information, the slope protection soil information includes soil moisture information and soil bulk density information from the bottom to the top of the slope;

[0007] Step S2, dividing the slope protection to be constructed into a first construction area and a second construction area based on the acquired soil moisture information;

[0008] Step S3, determining a splicing strategy for the slope protection box based on the construction area category;

[0009] Step S4, determining the step splicing profile according to the size of the slope protection box and the splicing distance of each layer of slope protection box from the bottom of the slope to the top of the slope;

[0010] Step S5, preliminarily determining the step rammed earth thickness and ramming strategy according to the rammed earth evaluation value;

[0011] Step S6, after jointly determining the slope protection earthwork contour according to the step splicing contour and the step rammed earth thickness, earthwork construction of the slope protection earthwork contour is performed;

[0012] Step S7, completing the rammed earth construction of each step and the pouring of the slope protection foundation cushion layer in sequence;

[0013] Step S8, pre-joining the slope protection boxes in the first construction area and the second construction area in sequence upward along the slope protection foundation cushion layer, wherein after the single-layer slope protection box is joined, backfilling the earth between the slope protection box and the slope protection;

[0014] Step S9, determining in turn according to the settlement offset values ​​whether the pre-joining of the single-layer slope protection box meets the preset standard.

[0015] Furthermore, in the step S2, the process of dividing the slope protection to be constructed into a first construction area and a second construction area based on the soil moisture information includes:

[0016] Get the humidity at each point from the bottom to the top of the slope;

[0017] comparing the humidity with a preset humidity threshold;

[0018] If the humidity is less than the preset humidity threshold, the slope protection area to be constructed is the first construction area;

[0019] If the humidity is greater than or equal to a preset humidity threshold, the slope protection area to be constructed is the second construction area.

[0020] Furthermore, in step S3, a splicing strategy of the slope protection box is determined based on the construction area category, wherein the splicing strategy of the first construction area is determined as equidistant splicing, and the splicing strategy of the second construction area is determined as gap splicing.

[0021] Furthermore, the splicing distance of the gap splicing is positively correlated with the difference between the soil moisture corresponding to the single-layer slope protection box and a preset moisture threshold.

[0022] Furthermore, in step S5, the step rammed earth thickness and rammed earth strategy are preliminarily determined according to the rammed earth evaluation value, wherein:

[0023] If the rammed earth evaluation value is less than the preset rammed earth evaluation characteristic value, the rammed earth thickness of the step is determined as the preset foundation thickness, and the rammed earth strategy of the step is determined as turning over the soil layer within the preset foundation thickness, mixing with lime and tamping to the size of the step joint outline;

[0024] If the rammed earth evaluation value is greater than or equal to the preset rammed earth evaluation characteristic value, the rammed earth thickness of the step is reduced according to the difference between the rammed earth evaluation value and the preset rammed earth evaluation characteristic value, and the ramming strategy of the step is determined to be directly rammed to the step splicing outline size.

[0025] Furthermore, the rammed earth evaluation value is determined based on soil moisture and soil bulk density.

[0026] Furthermore, the reduction range of the rammed earth thickness is positively correlated with the rammed earth evaluation difference, wherein the rammed earth evaluation difference is the difference between the rammed earth evaluation value and a preset rammed earth evaluation characteristic value.

[0027] Furthermore, in step S9, it is determined in turn whether the pre-joining of the single-layer slope protection box meets the preset standard according to the settlement offset value, wherein:

[0028] If the settlement offset value is less than the first preset offset value, it is determined that the pre-joining of the single-layer slope protection box meets the preset standard, and the jointing construction of the slope protection box is completed according to the current parameters;

[0029] If the settlement offset value is greater than or equal to the first preset offset value and less than the second preset offset value, it is determined that the pre-joining of the single-layer slope protection box does not meet the preset standard, and the rammed earth thickness of the corresponding layer step is increased according to the difference between the settlement offset value and the first preset offset value;

[0030] If the settlement offset value is greater than or equal to the second preset offset value, it is determined that the pre-splicing of the single-layer slope protection box does not meet the preset standard, and the splicing distance between the current layer of slope protection box and the next layer of slope protection box is increased according to the settlement offset difference, and the splicing construction of the next construction section is completed;

[0031] The settlement offset difference is the difference between the settlement offset value and the second preset offset value.

[0032] Furthermore, the splicing distance between the current layer of slope protection box and the next layer of slope protection box is increased according to the settlement offset difference, wherein:

[0033] If the settlement offset difference is less than the first preset offset difference, the low-amplitude distance adjustment coefficient is used to increase the splicing distance between the current layer of slope protection box and the next layer of slope protection box to a corresponding value;

[0034] If the settlement offset difference is greater than or equal to the first preset offset difference and less than the second preset offset difference, the mid-range distance adjustment coefficient is used to increase the splicing distance between the current layer of slope protection box and the next layer of slope protection box to a corresponding value;

[0035] If the settlement offset difference is greater than or equal to the second preset offset difference, the high-width distance adjustment coefficient is used to increase the splicing distance between the current layer of slope protection box and the next layer of slope protection box to a corresponding value.

[0036] Furthermore, in step S9, the process of obtaining the settlement offset value includes:

[0037] Get the location information of each slope protection box;

[0038] Carry out artificial settlement treatment on the pre-joined surface;

[0039] Obtain the location information of each slope protection box after artificial settlement treatment;

[0040] The average of the settlement offset of each slope protection box on the single-layer step before and after artificial settlement treatment is recorded as the settlement offset value.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention aims at the installation of spliced ​​slope protection, obtains slope protection soil information by surveying the river slope protection to be constructed, determines the splicing strategy of the slope protection box and the earthwork construction strategy, and after completing the pre-splicing, determines in turn according to the settlement offset value whether the pre-splicing of the single-layer slope protection box meets the preset standard, thereby adjusting the installation plan of the spliced ​​slope protection.

[0042] Furthermore, the present invention divides the slope protection to be constructed into a first construction area and a second construction area based on humidity, wherein the splicing strategy of the first construction area is equidistant splicing, and the splicing strategy of the second construction area is gap splicing. Different splicing strategies are adopted for different construction areas, thereby improving construction efficiency.

[0043] Furthermore, the present invention preliminarily determines the step rammed earth thickness and ramming strategy according to the rammed earth evaluation value. The rammed earth evaluation value is determined based on soil moisture and soil bulk density. If the rammed earth evaluation value is less than the preset rammed earth evaluation characteristic value, the soil layer within the preset depth is turned over, mixed with lime and compacted, thereby ensuring the uniformity of the soil and facilitating subsequent construction.

[0044] Furthermore, the present invention determines whether the pre-splicing of the single-layer slope protection box meets the preset standard according to the settlement offset value. If it does not meet the preset standard, the rammed earth thickness of the corresponding layer is increased accordingly, or the splicing distance between the slope protection box of this layer and the slope protection box of the next layer is increased, thereby effectively adjusting the construction plan and improving the quality of construction.

[0053] The embodiment of the present invention provides a green and environmentally friendly installation method of a spliced ​​slope protection, comprising:

[0054] Step S1, surveying the river channel slope protection to be constructed to obtain slope protection soil information, the slope protection soil information includes soil moisture information and soil bulk density information from the bottom to the top of the slope;

[0055] Step S2, dividing the slope protection to be constructed into a first construction area and a second construction area based on the acquired soil moisture information;

[0056] Step S3, determining a splicing strategy for the slope protection box based on the construction area category;

[0057] Step S4, determining the step splicing profile according to the size of the slope protection box and the splicing distance of each layer of slope protection box from the bottom of the slope to the top of the slope;

[0058] Step S5, preliminarily determining the step rammed earth thickness and ramming strategy according to the rammed earth evaluation value;

[0059] Step S6, after jointly determining the slope protection earthwork contour according to the step splicing contour and the step rammed earth thickness, earthwork construction of the slope protection earthwork contour is performed;

[0060] Step S7, completing the rammed earth construction of each step and the pouring of the slope protection foundation cushion layer in sequence;

[0061] Step S8, pre-joining the slope protection boxes in the first construction area and the second construction area in sequence upward along the slope protection foundation cushion layer, wherein after the single-layer slope protection box is joined, backfilling the earth between the slope protection box and the slope protection;

[0062] Step S9, determining in turn according to the settlement offset values ​​whether the pre-joining of the single-layer slope protection box meets the preset standard.

[0063] Specifically, in step S2, the process of dividing the slope protection to be constructed into a first construction area and a second construction area based on the soil moisture information includes:

[0064] Get the humidity at each point from the bottom to the top of the slope;

[0065] Comparing the humidity with a preset humidity threshold of 30%;

[0066] If the humidity is less than the preset humidity threshold, the slope protection area to be constructed is the first construction area;

[0067] If the humidity is greater than or equal to a preset humidity threshold, the slope protection area to be constructed is the second construction area.

[0068] Specifically, the points from the bottom to the top of the slope are sampled according to the grid point distribution method, and sampling points are set at the intersection of each grid. The horizontal distance and vertical distance between each point are 1m.

[0069] Specifically, the soil moisture measurement method, such as the resistance method, which is not specifically limited, is used to obtain the soil moisture at the sampling point.

[0070] Specifically, the average value of several points on each horizontal line of the grid is taken as the humidity of the point.

[0071] Specifically, in step S3, the splicing strategy of the slope protection box is determined based on the construction area category, wherein the splicing strategy of the first construction area is determined as equidistant splicing, and the splicing strategy of the second construction area is determined as gap splicing.

[0072] Specifically, the splicing distance of a single layer of the slope protection box is less than the width of the slope protection box, and the splicing distance of a single layer of the slope protection box is the horizontal distance between the center of the slope protection box of the current layer and the center of the slope protection box of the next layer.

[0073] Specifically, the equidistant splicing means that the splicing distance between every two layers of slope protection boxes is the same. The distance of the equidistant splicing is not specifically limited and can be determined based on the size of the slope protection boxes and the on-site construction conditions.

[0074] Specifically, the gap splicing means that the splicing distance of the slope protection box on this layer is different from the splicing distance of the slope protection box on the previous layer.

[0075] Specifically, the splicing distance of the gap splicing is positively correlated with the difference between the soil moisture of the layer corresponding to the single-layer slope protection box and the preset humidity threshold. The positive correlation can be a linear positive correlation or a nonlinear positive correlation. The slope of the linear positive correlation is not specifically limited. It only needs to satisfy that the greater the difference between the soil moisture corresponding to the single-layer slope protection box and the preset humidity threshold, the greater the splicing distance of the gap splicing.

[0076] Specifically, in step S5, the step rammed earth thickness and rammed earth strategy are preliminarily determined according to the rammed earth evaluation value, wherein:

[0077] If the rammed earth evaluation value is less than the preset rammed earth evaluation characteristic value of 0.5, the rammed earth thickness of the step is determined as the preset foundation thickness, and the rammed earth strategy of the step is determined as turning over the soil layer within the preset foundation thickness, mixing with lime and tamping it to the step joint outline size;

[0078] If the rammed earth evaluation value is greater than or equal to the preset rammed earth evaluation characteristic value, the rammed earth thickness of the step is reduced according to the difference between the rammed earth evaluation value and the preset rammed earth evaluation characteristic value, and the ramming strategy of the step is determined to be directly rammed to the step splicing outline size.

[0079] Specifically, the lime is slaked lime, and the amount of lime added is not specifically limited and can be determined based on specific construction parameters of the construction site.

[0080] Specifically, the rammed earth evaluation value is determined based on soil moisture and soil bulk density.

[0081] Specifically, the soil bulk density is measured by, for example, the ring knife method, which is not specifically limited.

[0082] Specifically, the rammed earth evaluation value is calculated by the following formula:

[0083]

[0084] In the formula, E represents the rammed earth evaluation value, α represents the first evaluation coefficient, and α is set to 0.75, H represents soil moisture, Hy represents the soil moisture threshold, and Hy is set to 25%, β represents the second evaluation coefficient, and β is set to 0.20, ρ represents soil bulk density, ρy represents soil bulk density threshold, and ρy is set to 1.5 g / cm 3 .

[0085] Specifically, the reduction amplitude of the rammed earth thickness is positively correlated with the rammed earth evaluation difference, wherein the rammed earth evaluation difference is the difference between the rammed earth evaluation value and the preset rammed earth evaluation characteristic value. It can be understood that the larger the rammed earth evaluation difference, the larger the reduction amplitude of the rammed earth thickness. The positive correlation can be, for example, linear positive correlation and nonlinear positive correlation, wherein the slope of the linear positive correlation is not specifically limited.

[0086] Specifically, in step S9, it is determined in turn whether the pre-joining of the single-layer slope protection box meets the preset standard according to the settlement offset value, wherein:

[0087] If the settlement offset value is less than the first preset offset value of 5.80 mm, it is determined that the pre-joining of the single-layer slope protection box meets the preset standard, and the jointing construction of the slope protection box is completed according to the current parameters;

[0088] If the settlement offset value is greater than or equal to the first preset offset value and less than the second preset offset value of 12.00 mm, it is determined that the pre-joining of the single-layer slope protection box does not meet the preset standard, and the rammed earth thickness of the corresponding layer step is increased according to the difference between the settlement offset value and the first preset offset value;

[0089] If the settlement offset value is greater than or equal to the second preset offset value, it is determined that the pre-splicing of the single-layer slope protection box does not meet the preset standard, and the splicing distance between the current layer of slope protection box and the next layer of slope protection box is increased according to the settlement offset difference, and the splicing construction of the next construction section is completed;

[0090] The settlement offset difference is the difference between the settlement offset value and the second preset offset value.

[0091] Specifically, the splicing distance between the slope protection box of the current layer and the slope protection box of the next layer is increased according to the settlement offset difference, wherein:

[0092] If the settlement offset difference is less than the first preset offset difference of 3.00 mm, the low-amplitude distance adjustment coefficient of 1.02 is used to increase the splicing distance between the current layer of slope protection box and the next layer of slope protection box to the corresponding value;

[0093] If the settlement offset difference is greater than or equal to the first preset offset difference and less than the second preset offset difference of 5.00 mm, the middle distance adjustment coefficient of 1.05 is used to increase the splicing distance between the current layer of slope protection box and the next layer of slope protection box to the corresponding value;

[0094] If the settlement offset difference is greater than or equal to the second preset offset difference, the high-width distance adjustment coefficient of 1.10 is used to increase the splicing distance between the current layer of slope protection box and the next layer of slope protection box to the corresponding value.

[0095] Specifically, in step S9, the process of obtaining the settlement offset value includes:

[0096] S901, obtaining the position information of each slope protection box;

[0097] S902, artificial sedimentation treatment is carried out on the pre-joined surface at 12L / h / m 2 The irrigation treatment was carried out at a water flow rate of 1 hour each time, and the treatment was carried out every 6 hours;
