Problems solved by technology

[0005] 1. Manual control requires workers to support the spray gun all the time during the spraying process, and adjust the flow rate according to the position to be sprayed. Large, will increase the workload;
[0006] 2. Due to the centrifugal force of the stirring device, the wood fiber particles are thrown around the stirring device, which will cause the accumulation of wood fiber particles on the sides, affect the stirring degree of the wood fiber, and reduce the concentration of the wood fiber mixture;
[0007] 3. Depending on the location of spraying, it is necessary to apply different concentrations of wood fiber mixture, but at present, when you want to change the concentration of wood fiber, the adjustment method is to change the amount of water added, and the adjustment speed is slow, which affects the spraying efficiency;
[0008] 4. The existing way to adjust the spraying amount and spraying speed of the wood fiber mixture is to adjust the power of the pumping device, which requires the installation of an electronic control device, which increases the cost and increases the difficulty of control

Embodiment 1

[0042] A construction method of heavy metal soil covered with green soilless wood fiber spraying, comprising the following steps:

[0043] S1: Slope cleaning, set up a safety protection zone to prohibit pedestrians and vehicles from passing, manually remove gravel and dangerous stones on the slope, and apply equipment to the smooth slope to ensure that the matrix material can be stably attached to the rock mass;

[0044] S2: Set up intercepting ditches, and set up intercepting ditches at the top of the slope to prevent ground catchment water from washing the slope surface during rainfall and causing slope damage; when cleaning the slope surface, trim the corners and corners of the slope surface into arcs to facilitate spray The stability of the podcast soil;

[0045]S3: Lay the fixed net: the slope surface is reinforced with high-strength plastic geonet, and the geonet should be laid from top to bottom to ensure that the width of the laid link joint is not less than 7cm, and t...

Embodiment 2

[0049] Such as figure 1 As shown, a spray gun includes a spray gun 4, and the spray gun 4 includes a transport pipe 100, a hose 110, a positioning bolt 121, an upper joint 122, a lower joint 123, a spray pipe 130, a nozzle 140, a fixed rod 150, a lifting hydraulic cylinder 160, Return pipe 170, isolation plate 180, telescopic baffle 181;

[0050] The nozzle 130 is installed on the lower joint 123, and the nozzle 130 is sequentially installed with a fixed rod 150, a lifting hydraulic cylinder 160, a return pipe 170 and a spout 140 from back to front;

[0051] The fixed rod 150 is a hard round rod, the lower end is fixed on the upper plate of the sprayer, and the upper end passes through the side wall of the spray pipe 130 and is connected to the isolation plate 180 to complete the positioning of the isolation plate 180, and the nozzle pipe 130 can be fixed to the fixed rod 150 as Center rotation;

[0052] The lower end of the lifting hydraulic cylinder 160 is installed on the...

Embodiment 3

[0079] Such as Figure 10 Shown, a kind of sprinkler comprises the spray gun 4 described in embodiment 1, stirring device 6, also comprises mixing device 7, pumping device 5, feed inlet 8;

[0080] The feed inlet 8 is an entrance for putting the wood fiber mixture into the spray seeder;

[0081] Described mixing device 7 is the working space that wood fiber mixture is mixed with water, and mixing device 7 is connected with mixing device input pipe 2;

[0082] The pumping device 5 is a power source that provides the upward transport power of the wood fiber mixture

Abstract

The invention relates to the technical field of spray-seeding construction methods, in particular to a heavy metal soil green-covering soil-free wood fiber spray-seeding construction method. The method comprises the following steps: slope surface cleaning; intercepting ditch arrangement; fixing net laying; matrix material preparation; spray-seeding. Specifically, firstly, water is sprayed to wet a slope, so as to enable matrix material to be uniformly attached to the surface of the slope, a substrate material without grass seeds is uniformly sprayed and seeded on the side slope to serve as a bottoming material, the substrate material and mixed grass seeds are poured into a mixing device to be fully stirred, the uniformly-stirred substrate mixture is poured into a spray-seeding machine to be sprayed until the spray thickness reaches 125% of the design requirement, and the thickness is uniform; the spray-seeding machine comprises a spray gun, a stirring device, a mixing device, a pumping device, and an inlet port; The area of a nozzle is adjusted while a spray-seeding pitching angle is adjusted, the spray-seeding lift is changed, manpower is saved, and the overall automation degree is increased.

Description

technical field [0001] The invention relates to the field of spraying construction methods, in particular to a construction method for spraying heavy metal soil covered with green soil-free wood fibers. Background technique [0002] Nowadays, the guest soil sprayer has gradually replaced the position of the dry sprayer and the concrete delivery pump in the slope greening construction. Convenience, disadvantages of construction danger. The so-called guest soil spraying machine is to mix grass seeds, shrubs, tree species, etc., with water retaining agents, adhesives, plant fibers, planting soil and fertilizers, etc., with water in a mixing tank to form a viscous mixed slurry. The thick slurry pump sprays it on the slope. [0003] Because the mixed slurry contains water retention, binding materials and various nutrients, it ensures the water and other sources of nutrients needed for plant growth, so plants can grow healthily and rapidly, and at the same time shorten the maint...
