Abstract

The invention discloses a pressure pipeline leakage detection pipe ditch for collapsible loess regions. A plant pressure pipeline is disposed in a leakage detection pipe ditch (1), the top of the leakage detection pipe ditch (1) is provided with vent holes (4) and leakage detection wells (3), the bottom of the leakage detection pipe ditch (1) is provided with water collection wells (2), and a drain pipe (7) is disposed in each water collection well (2) and connected with a rainwater inspection well (5). Leaking water from the pressure pipeline is finally drained to a sewage treatment station for treatment or drained out of a plant through plant rainwater drain pipelines (6). By using the pressure pipeline leakage detection pipe ditch, the problem of water leakage of the pressure pipelines in the collapsible loess region is solved, the deficiencies of standard atlas of leakage detection pipe ditches in the collapsible loess regions can be complemented, and the pressure pipeline leakage detection pipe ditch has the advantages of safety, practicality and the like.

Description

The pressure pipeline leak detection pipe trench of Collapsible Loess District
Technical field
The present invention relates to a kind of pressure pipeline leak detection pipe trench of Collapsible Loess District.
Background technology
Collapsible loess is the commonplace engineering geological conditions in NORTHWEST CHINA area; Its soil property characteristics and engineering harm show as when meeting water-soaked; Make loess generation humidification softening effect; The intensity of soil significantly reduces, and causes the saturated yielding distortion in additonal pressure or under the gravity pressure of additonal pressure and soil, is the loess that a kind of deflection is big, subsidence velocity is fast.The distortion of the de-stabilise of collapsible loess, therefore very harmful to building need to solve the leak detection problem of water supply and sewerage pipeline.
Landforms are tableland, loess tableland plateau limit under the electrolytic aluminium factory of Shaanxi; Whole plant area is in partly to fill out partly digs non-rock side slope; Remove the non-self weight collapse loess of the southeast subordinate of plant area; Most of location belongs to self weight collapse loess, and self weight collapse loess shows as loess and receives water-soaked last applying under the native gravity pressure, and loess can take place significantly to add.Ground saturated yielding grade is the IV level, and the thickness distribution of full factory yellow soil horizon of collapsibility is between 16.9 to 27 meters, and average thickness is 20 meters, belongs to serious collapsible loess district.
Code for building construction in collapsible loess zone that present China is existing and plumbing standard drawing have only been introduced the leak hunting method of water supply and sewerage pipeline in the protection distance; But " Code for building construction in collapsible loess zone " (GBJ 25-90) 3.2.4 bar regulation: ground saturated yielding grade is III, IV level Collapsible Loess District; The thickness of settlement by soaking soil layer is during greater than 12m, and the one-tenth-value thickness 1/10 that the protection distance between pressure pipeline and all kinds of building should be pressed the settlement by soaking soil layer adopts.Therefore be III, IV level Collapsible Loess District in ground saturated yielding grade; The thickness of settlement by soaking soil layer is during greater than 12m; When total figure can't satisfy the protection distance of pressure pipeline installation in the position; Pressure pipeline need all be arranged in the leak detection pipe trench, and how to arrange that the leak detection pipe trench of pressure pipeline is the problem that needs solution.
Summary of the invention
The technical problem that the present invention will solve is: the pressure pipeline leak detection pipe trench that a kind of Collapsible Loess District is provided; To overcome pressure pipeline that prior art the exists deficiencies such as saturated yielding of leaking, the disappearance that can replenish existing Collapsible Loess District leak detection pipe trench standard collective drawings simultaneously.
The present invention constitutes like this: plant area's pressure pipeline is arranged in the leak detection pipe trench, and leak detection pipe trench top is provided with air vent, leak detection well, and leak detection tube ditch bottom is provided with collecting well, and gutter is arranged in the collecting well and with rainwater inspection well and communicates.
Leak detection tube ditch bottom surface is provided with 5 ‰ the gradient, reduces to the collecting well direction.
The corresponding setting of leak detection well with collecting well.
Collecting well, leak detection well, air vent whenever lay one at a distance from 40~60 meters.
The present invention establishes the leak detection well on collecting well top, finds pipeline leakage through daily tour leak detection well, in time service conduits; The air vent that leak detection pipe trench top is provided with is used for staff's service conduits ventilation usefulness in the leak detection pipe trench, avoids causing security incident; When pipeline generation booster leaked, water confluxed to collecting well, drains into rainwater inspection well through gutter, finally drained into outside Sewage Disposal or the factory through plant area's rain drainage pipe; Collecting well, leak detection well, air vent need lay according to actual conditions at a certain distance, general whenever are provided with one at a distance from 50 meters.
The saturated yielding problem because the pressure pipeline that has adopted technique scheme, the present invention to efficiently solve Collapsible Loess District leaks has advantages such as safe, practical.
Description of drawings
Fig. 1 is a floor map of the present invention.
Fig. 2 is an A-A sectional drawing of the present invention.
Fig. 3 is a B-B sectional drawing of the present invention.
The specific embodiment
Embodiments of the invention: plant area's pressure pipeline is arranged in the leak detection pipe trench 1; Leak detection pipe trench 1 top is provided with air vent 4, leak detection well 3; Leak detection pipe trench 1 bottom is provided with collecting well 2; Gutter 7 is arranged in the collecting well 2 and with rainwater inspection well 5 and links to each other, and pressure pipeline percolating water finally drains into outside Sewage Disposal processing or the factory through plant area's rain drainage pipe 6.
Leak detection pipe trench 1 is by 5 ‰ gradient aspect collecting wells 2, and leak detection well 3 is established on collecting well 2 tops, finds that through daily tour leak detection well 3 pipeline has leakage loss when pipeline has leakage loss, in time service conduits; The air vent 4 that leak detection pipe trench 1 top is provided with is used for staff's service conduits ventilation usefulness in leak detection pipe trench 1, avoids causing in staff's ditch and suffocates; When pipeline generation booster leaked, water confluxed to collecting well 2, and near the rainwater inspection well 5 draining into through gutter 7, pressure pipeline percolating water finally drain into outside Sewage Disposal processing or the factory through plant area's rain drainage pipe 6; Collecting well 2, leak detection well 3, air vent 4 need lay one at a distance from 40~60 meters according to actual conditions.
