The protection capacity of the slope is improved by concrete pouring, but the control accuracy of the slope protection lattice beam is low during the production of the slope protection lattice beam formwork, and the control accuracy of the depth of the lattice beam groove is low.

A pair of overlapping grooves between two adjacent prefabricated nodes are aligned in a straight line, and prefabricated lattice beams connecting adjacent prefabricated nodes are arranged in the overlapping grooves, and connecting components are arranged between the overlapping grooves and the prefabricated lattice beams; the construction method includes the following steps: processing prefabricated nodes and prefabricated lattice beams; cleaning and positioning the slopes; connecting prefabricated nodes and prefabricated lattice beams; pouring concrete; grouting and anchoring. The prefabricated lattice beam slope protection structure with a regular triangular arrangement in the present invention adopts prefabricated nodes and prefabricated lattice beams, and adopts the form of on-site assembly, which improves construction efficiency, reduces labor costs, and is conducive to the promotion and use of assembled concrete structures; it can be seen that the triangularly arranged assembled lattice beam slope protection structure and its construction method have the following problems:

[0005] 2. The depth control accuracy of the lattice beam groove is low, which may easily cause slope displacement due to high annual precipitation or high water level in the construction site; Summary of the invention
[0006] To this end, the present invention provides a rapid construction method for slope protection lattice beams, which is used to overcome the problems of low control accuracy of lattice beam grooves and low control accuracy of lattice beam groove depth in the prior art.
[0007] To achieve the above object, the present invention provides a rapid construction method for a slope protection lattice beam, comprising:
[0008] Step S1, measuring and laying out on the leveled slope;
[0009] Step S2, making a frame template of the lattice beam and marking the center line or contour line of the preset position of the lattice beam;

[0012] Step S5: Supervisory warehouse inspection;
[0013] Step S6, performing lattice beam concrete pouring construction;
[0014] Step S7, demoulding and concrete curing;
[0015] In step S2, when making the frame template of the lattice beam, the initial density of the slope protection lattice beam is determined according to the slope, the hardness coefficient of the land is determined according to the soil type, and the soil weight coefficient of each soil type is determined according to the volume of each soil type and the total volume of the construction land to determine the comprehensive index of the land, and the density of the lattice beam is adjusted according to the comprehensive index of the land and the average annual precipitation or the depth of groundwater.
[0016] In the step S2, when making the lattice formwork of the lattice beam, the initial density of the slope protection lattice beam is determined according to the comparison result of the slope and the preset slope, the preset slope includes a first preset slope and a second preset slope, the first preset slope is greater than the second preset slope, and the second initial density is greater than the third initial density and less than the first initial density;

[0019] If the slope is less than or equal to the second preset slope, the initial density of the slope protection lattice beam is determined to be a third initial density.
[0020] When the initial density of the slope protection lattice beam is determined, the hardness coefficient of the land is determined according to the soil type;
[0021] If n≥6, the hardness coefficient of the land is determined to be the first hardness coefficient;
[0022] If 6>n≥3, the hardness coefficient of the land is determined to be the second hardness coefficient;

[0025] After determining the hardness coefficient of the soil, determine the volume of each soil type and the total volume of the construction site to calculate the weight coefficient Q of each soil type, and set
[0026] Q=(Un / Uz)×G(1)
[0027] Among them, Un is the volume of the nth soil type, Uz is the total volume of the construction land, and G is the hardness coefficient.
[0028] After determining the soil weight coefficient of each soil type, the comprehensive index S of the land is determined according to the initial density, the hardness coefficient of the land and the soil weight coefficient of each soil type, and the soil weight coefficient of each soil type is set.

[0046] In the present invention, the comprehensive index of the land is determined according to the hardness coefficient of the land and the soil weight coefficient, thereby improving the precise control of the soil quality. Further, it is determined whether to adjust the density of the slope protection lattice beam according to the comprehensive index of the land, thereby improving the precise control of the slope protection lattice beam and reducing the problem of slope dislocation caused by soil quality problems.
[0047] The present invention determines the adjustment method of the density of the slope protection lattice beam through the comprehensive index and the preset comprehensive index, thereby improving the precise control of the density of the slope protection lattice beam.
[0048] Furthermore, the present invention adjusts the density of the lattice beam according to the annual precipitation of the construction site, thereby improving the precise control of the actual conditions of the construction site, improving the precise control of the density of the lattice beam, and reducing the problem of soil loss on the slope.
[0049] Furthermore, in the present invention, the smaller the depth of the groundwater, the greater the possibility of the slope shifting, and the greater the required slope protection strength. The present invention readjusts the density of the slope protection lattice beams according to the groundwater level, thereby improving the precise control of the actual situation of the construction site and the precise control of the density of the slope protection lattice beams.
[0050] Furthermore, in the present invention, the higher the highest water level in the rainy season, the greater the possibility of slope displacement, and the greater the required slope protection strength.
