Abstract
The utility model relates to an inclination detecting pipe in a refuse landfill, which is provided with an inner groove on the inner sidewall, wherein the inclination detecting pipe is made of high-density polyethylene; the parts of the inclination detecting pipe, adjacent to two end parts, and the wall of a sleeve pipe, are axially provided with locating holes. The inclination detecting pipe is suitable for long-term inclination detection monitoring of the refuse landfill without needing frequent replacement; and multiple inclination detecting pipes are connected and positioned conveniently.
Description
Technical field
The utility model relates to a kind of deviational survey pipe that refuse landfill is carried out long term monitoring.
Background technology
Along with the development in city, refuse pollution causes people's attention gradually, and becomes one of the great environmental problem that need put forth effort to solve.Advantages such as garbage loading embeading possesses skills reliably, technology is simple, convenient management, small investment are present stage China and the trash processing way of many developed countries first-selection.
The refuse landfill of China mostly is the mountain valley-type landfill yard, rubbish is according to the natural slope landfill in mountain valley, and modern refuse landfill all is " high, big " type, landfill rubbish on the slope is easy to unstability under the conditions such as complicacy of rubbish deadweight, rainfall and component of refuse, cause enormous economic loss, to the real-time inclination monitoring of refuse landfill for safeguarding that landfill yard slope stability has crucial meaning.
The deviational survey process needs the deviational survey pipe is imbedded underground 20～50m, deviational survey tubing matter is generally Polyvinylchloride (PVC) or butadiene-acrylonitrile-styrol copolymer (ABS), PVC or ABS have good cold plasticity, can once finish by the moulding kerve, be about to material and put into the mould of kerve, the pipe of hot briquetting exports hardening by cooling, directly forms the deviational survey pipe of operable PVC material.The rubbish generation degraded of landfill yard produces the material of severe corrosive, and as percolate, the use of deviational survey pipe will be corroded crisply in about 1 year, can't work on, the therefore present domestic short-term inclination monitoring that only landfill yard is carried out 1 year by a definite date.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of refuse landfill deviational survey pipe, is applicable to the long-term inclination monitoring to landfill yard rubbish, need not frequently change, and the opinion of a plurality of deviational survey pipes connects the location conveniently.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme:
Refuse landfill deviational survey pipe, madial wall has groove, it is characterized in that the deviational survey pipe is near driving pilot hole vertically on the position at both ends and the sleeve pipe.
Aforesaid refuse landfill deviational survey pipe, the material that it is characterized in that the deviational survey pipe is a high density ethylene.
The design feature and the beneficial effect of refuse landfill deviational survey pipe of the present utility model are:
1, adopts high density ethylene (HDPE) to make material, have good anti-corrosive properties, can realize long term monitoring the refuse landfill deviational survey.
2, because high density ethylene (HDPE) cold plasticity is poor, can't use traditional deviational survey pipe processing mold, can't one-shot forming deviational survey pipe, inside groove and anchor point, therefore on the outer wall of deviational survey pipe, offer pilot hole, employing pilot hole location, pilot hole is circumferentially evenly arranged 2 groups totally 4 along the deviational survey pipe.The utility model uses in Wuxi peach blossom mountain refuse landfill, Shenzhen Xia Ping refuse landfill, improves 10～20 times than traditional deviational survey pipe life cycle.
Description of drawings
Fig. 1 is the utility model refuse landfill deviational survey tubular construction synoptic diagram;
Fig. 2 is two refuse landfill deviational survey pipe annexation synoptic diagram;
Fig. 3 is the utility model refuse landfill deviational survey pipe inside groove synoptic diagram.
The explanation of main mark in the accompanying drawing: 1 is the deviational survey pipe, and 2 is pilot hole, and 3 is sleeve pipe, and 4 is the kerve ring, and 5 are the fluting point.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model refuse landfill deviational survey tubular construction synoptic diagram.Fig. 2 is two refuse landfill deviational survey pipe annexation synoptic diagram.Shown in Fig. 1,2, refuse landfill deviational survey pipe 1, diameter are 70mm, and length is 2m, material is HDPE, anti-corrosive properties are strong, drive pilot hole 2 at the deviational survey pipe near the position at two ends, when a plurality of deviational survey pipes connect, position alignment with the inside groove and the pilot hole of different deviational survey pipes, the sleeve pipe 3 that will be provided with pilot hole then equally is enclosed within the junction, and pin is inserted the pilot hole internal fixation, and inside groove is accurately aimed at when guaranteeing the multitube connection.
Fig. 3 is the inner fluting of a utility model refuse landfill deviational survey pipe synoptic diagram.With reference to shown in Figure 3, the anti-corrosive properties of HDPE deviational survey pipe are strong, but cold plasticity is relatively poor, subsides at once behind the kerve, can't moulding, can't use traditional one-time formed Mould Machining, deviational survey pipe of the present utility model is to process deviational survey pipe, back working groove earlier: i.e. elder generation's blowing on blow moulding machine goes out not have the HDPE pipe of groove, then the deviational survey pipe is fixed on the support, the kerve ring 4 that will have fluting point 5 with cold drawn mode is moved the pipe tail to from the mouth of pipe in managing, guaranteed that the HDPE pipe is indeformable.
It is as follows to the long-term inclination monitoring process of refuse landfill to use deviational survey pipe of the present utility model:
(1), rig boring, boring procedure notes adding pillar, because a large amount of gases of garbage degradation accumulate in and produce bigger air pressure in the landfill yard, if do not add pillar, is bored into certain depth, the hole of collapsing easily, the zone that has bored on top causes boring to carry out.
(2), when boring moulding after, insert the deviational survey pipe immediately, when the deviational survey pipe is put into whole hole, that deviational survey pipe top is good with cap seal.
(3) will have the pulley gear of clinometer probe, put into deviational survey pipe inside by the inside groove of deviational survey pipe, the pulley gear stube cable, during observation, probe moves to the top gradually from deviational survey pipe bottom, the degree of tilt of probe is measured gained by the servo accelerometer of two stress balances, contrasts current and initial observation data, can determine the variable quantity of laterally offset.
Above-mentioned embodiment does not limit the technical solution of the utility model in any form, and the technical scheme that mode obtained that every employing is equal to replacement or equivalent transformation all drops on protection domain of the present utility model.
Claims (2)
1. refuse landfill deviational survey pipe, madial wall has groove, it is characterized in that the deviational survey pipe is near driving pilot hole vertically on the position at both ends and the sleeve pipe.
2. refuse landfill deviational survey pipe according to claim 1, the material that it is characterized in that the deviational survey pipe is a high density polyethylene.
