Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-2, the raw ore heap rainwater collection system includes a hardened ground 1, a trench 2, and a rainwater collection pool 3, wherein the hardened ground 1 is provided with the rainwater collection pool 3, and the hardened ground 1 is provided with the trench 2 communicated to the rainwater collection pool 3, in this embodiment, the trench 2130m is long and 500mm wide, and the size of the rainwater collection pool 3 is 8m 5m 3.5 m. The rainwater collecting tank 3 is internally provided with a submersible pump connected with a water storage tank. Whole sclerosis ground 1 designs for outside a week is higher, and inboard a week is lower has the structure of slope, consequently collects the rainwater 1 inboard a week rainwater catch pit 3 on sclerosis ground, sets up irrigation canals and ditches 2 and immersible pump 8 simultaneously, retrieves to water storage tank 9 to be used for the workshop production with the clear water after filtering.

Hardened ground 1 includes tamped soil base layer 4, natural gravel bed course 5, graded grit base layer 6, concrete surface course 7, pours tamped soil base layer 4 by bottom to top in proper order, natural gravel bed course 5, graded grit base layer 6, concrete surface course 7, and hardened ground 1 divides into four layers, and in this embodiment, first layer tamped soil base layer 4, second floor 150mm natural gravel bed course 5, third layer 250mm graded grit base layer 6, the thick C30 concrete surface course 7 of fourth layer 250 mm.

The measurer combines the original height of the ground to determine the height difference and slope ratio in the whole yard. The hooking machine enters the field to dig and support the original ground by 0.25M, leveling is carried out, the road roller is matched with the original ground which is leveled by the hooking machine to roll and tamp, the ground is leveled according to the design requirement, and the slope is five per thousand. The construction positioning line is mainly used for controlling the elevation of the channel steel side die, the designed thickness of concrete is 250mm, the channel steel side die is used, the top surface of channel steel is arranged on the top surface of the laid-off elevation, and the place with insufficient height is filled with stones and leveled. After fixing, the elevation of the top of the template is checked by a level gauge. The method comprises the steps of sequentially pouring a rammed concrete base layer 4, a natural gravel cushion layer 5, a graded gravel base layer 6 and a concrete surface layer 7, wherein the concrete is type C30 concrete, the concrete is constructed in a longitudinal strip division mode, a vibrating rod is used for vibrating after the concrete is poured, a scraping machine is placed on channel steel, and the concrete surface is scraped by an operator. After the concrete is leveled and compacted, the concrete is statically stopped for about 4 hours to make the concrete in a critical initial setting period, and the judging method comprises the following steps: the foot is stepped on the upper surface and the foot print sinks by 5 mm. And (3) carrying out surface slurry lifting, brushing, compacting, unloading a sand table, directly starting mechanical polishing by using the trowelling machine, brushing after polishing is finished, curing after concrete is poured for 24 hours, covering by adopting geotextile, and spraying water for curing. In order to overcome the crack generated by the temperature change, a cutting machine is required to be used for cutting on the poured concrete ground perpendicular to the pouring direction of the concrete. The time of slitting should be controlled strictly, and premature slitting can loosen the stones and damage the edges. The seam is difficult to cut too late, and the two ends of the seam are easy to crack irregularly. The compressive strength of the concrete reaches 6-10 MPa in a proper time. And performing slotting construction after curing for 3 days in the season.

And (3) according to the corresponding contour lines, placing the edge lines of the trench bottom trench, drawing the edge lines on the ground by using lime, excavating by using a manually-matched excavating machine, transporting by using a dump truck, and excavating to 10-15cm away from the designed dimension by using manual excavation. And manually trimming to the designed size, so that the ditch bottom and the original soil layer of the slope cannot be disturbed, and overexcavation is not allowed. After the foundation trench is excavated, firstly self-checking is carried out, after mutual checking is qualified, a project department reports to a field supervision engineer for checking, and after all checking is qualified, concrete pouring work of the ditch 2 and the collecting tank is accurately carried out.

The material can be used after being detected to be qualified when entering a field, and concrete is prepared strictly according to the construction mixing proportion, so that the sufficient stirring time is ensured, and various indexes of the concrete, such as slump and the like, need to meet the standard requirements. The concrete is transported by using a self-unloading tricycle, and the concrete is manually injected into the template. The vibration adopts an inserted vibrator, the vibration points are required to be uniform in the vibration process, and the vibration time is suitable for preventing the concrete surface from sinking and preventing bubbles from rising from the side edge of the template. The surface of the concrete is kept wet all the time within 7-10 days after the concrete is poured. The plastic film is used for covering and wrapping in the health preserving process, watering is ensured to be carried out more than twice every day, and the watering frequency is properly increased in hot days, so that the surface of the concrete is preferably kept in a wet state.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
