Embodiment Construction

[0033] Refer to the attached figure 1 and 2 , a construction method for a landfill gas collection shaft, comprising the following steps:

[0034] a) erect the bracket 12 of the drilling equipment at the predetermined construction position, and the upper part of the bracket is provided with a fixed pulley 2;

[0035] b) a steel wire rope 3 passing through the fixed pulley is set, and a hoist 5, a diesel engine 6 and a control cabinet 4 matching the steel wire rope are arranged to control the winding of the steel wire rope;

[0036] c) hang a grab bucket 9 with a connection part preset at the bottom under the wire rope, and set a control device for controlling the opening and closing of the grab bucket; perform the following steps after completing the installation of the hole-forming equipment;

[0037] d) controlling the grab to open and release, causing it to drive into the predetermined hole-forming position;

[0038] e) After closing the grab to grab the material, lift th...

Abstract

The invention discloses a landfill gas gas-collecting shaft construction method, which adopts grabbing-bucket digging well method to dig the gas-collecting shaft, and the completed gas-collecting shaft has good permeability, and high gas-collecting efficiency. The grabbing-bucket is controlled through a steel rope, the length can be controlled; and the gas-collecting shaft with deep depth can be constructed according to needs, meanwhile, the control method can simplify the structure. Pebbles or gravels are poured into a gas-collecting vertical hole at the outside of a gas-collecting pipe to the top of the garbage layer, and the periphery of the gas-collecting shaft on the garbage layer is provided with bentonite, and the bentonite is tamped to form a sealing structure, accordingly, the efficiency can be further increased.

Description

technical field [0001] The invention relates to a construction method for a landfill gas collection shaft, and belongs to the technical field of landfill gas collection and utilization. Background technique [0002] After anaerobic fermentation, the garbage in the landfill produces a large amount of landfill gas. The landfill gas contains about 60% methane, which is a recyclable resource. The efficient collection of landfill gas is the premise of realizing its comprehensive utilization, and the construction of gas-gathering shaft is the premise of landfill gas collection. The quality of gas-gathering shaft directly affects the collection efficiency of landfill gas. Among them, the construction method of forming holes in the gas-gathering shaft is the key point to realize the efficient collection of landfill gas. [0003] A typical gas gathering well is formed by erecting a drilling machine with an auger bit, drilling into the landfill layer to form a vertical hole, and then...
