Embodiment Construction

[0053] Such as figure 1 Shown is the covering system 100 of the sewage conditioning tank of a waste landfill of the present invention, which includes a floating cover film 10, a gravity ballast device 20, a gas guiding device 30, an anchoring device 40, a pedestrian passage 50 or a water-proof pedestrian passage 60, Maintenance hole device 70.

[0054] Such as Figure 1-7 As shown, the floating cover film 10 is a whole formed by welding several pieces of 2.0mm thick double-gloss HDPE film. The floating cover film covers the water surface of the sewage conditioning tank 200, and the edges of the floating cover film are anchored The device 40 is anchored outside the adjustment tank, and the floating cover film seals the sewage surface in the adjustment tank, and can float and fluctuate with the change of the sewage level of the liquid level in the adjustment tank. The floating cover film 10 of the present invention must use materials with good impermeability and anti-aging properti...

Abstract

The invention discloses a wet construction method which is used for constructing and building an anticorrosion coverage system of a flexible floating coverage film on a refuse landfill sewage adjusting tank filled with sewage, wherein the anticorrosion coverage system can prevent the bad smell of the adjusting tank from diffusing, prevent rain and sewage from mixing, conveniently collect methane and conveniently extract and discharge rain. The construction procedures are as follows: cleaning impurities on the surface of sewage in the tank; installing a gas collecting tube; building an overwater working platform (floating bridge device); cutting, overlaying, anchoring, welding and detecting a floating coverage film; installing a floating ball string device, a pedestrian path and a maintenance hole device; moving the working platform; repeatedly installing the floating coverage film, the pedestrian path on the film and the floating ball string device below the film; removing the workingplatform; installing a gravity ballasting system; and installing a gas delivery tube. On the floating bridge device, the performance of the welding line of the floating coverage film can be detected until the welding line is qualified, and the pedestrian path, the floating ball string device and the maintenance hole device can be installed; after one section is finished, the floating bridge device can be moved for the construction of the next section; and thus, wet construction is realized.

Description

Technical field [0001] The present invention relates to a construction method of a garbage landfill, in particular to a wet construction method for constructing a covering system on a sewage conditioning tank of a garbage landfill that has been filled with sewage. Background technique [0002] General large-scale domestic waste landfills are divided into corresponding supporting areas such as office management area, landfill storage area, sewage conditioning tank, sewage treatment plant, biogas treatment plant, machine repair workshop, etc. According to relevant national regulations, landfill storage area and sewage conditioning tank HDPE film (high-density polyethylene film) and other anti-seepage materials must be used for artificial anti-seepage treatment. The leachate produced by the garbage in the landfill reservoir flows to the sewage conditioning tank through the leachate collection pipe, and finally enters the sewage treatment plant, and is discharged after the treatment ...
