Abstract

A section shape of an intercepting blind drain is trapezoid with big top and small bottom. Two lateral groove walls of the intercepting blind drain are lateral groove walls which are respectively inclined to the opposite direction and the groove wall at one side and the groove bottom of the intercepting blind drain are made by the anti-seepage type material and the groove wall at other side is made by the permeable type material. The intercepting blind drain is equipped at the appropriate position of the upper stream of the groundwater in the electrolytic plant and the lateral groove wall of the intercepting blind drain made by the anti-seepage type material is equipped at one side near the electrolytic plant and the other lateral groove wall of the intercepting blind drain made by the permeable type material is equipped at one side fat from the electrolytic plant when the intercepting blind drain is used, which can effectively prevent the electrolytic groove and the bus base foundation from being soaked and being softened by the groundwater to result in the sinking of the base.

Description

French drain intercepts water

Technical field:

The utility model relates to a kind of french drain that intercepts water, and the phreatic french drain that intercepts water in particularly a kind of potroom upstream that is used to dam belongs to the industrial construction technical field.

Background technology:

At present, in the construction of electrolytic aluminium factory, when underground water level higher, and electrolytic cell adopts ground pit type or half ground pit type, or the flooring of potroom is when lower than outdoor ground, and electrolytic cell and bus basis can occur soaking phenomenon, cause the ground deliquescing, when on-load is produced, cause immerge easily, the french drain that intercepts water need be set cut off of the immersion of upstream underground water electrolytic cell and bus basis.And the existing french drain that intercepts water generally adopts the french drain that intercepts water of rectilinear rectangle wall type, and its lateral sulcus wall all adopts antiseepage section bar material to make.This french drain that intercepts water is because the restriction of its structure, construction trouble, cost height; And the furrow bank of this french drain that intercepts water adopts antiseepage section bar material to make, and the underground water of upstream can not enter the french drain that intercepts water well, causes french drain not dredge underground water effectively, and the effect that intercepts water is not ideal enough.

Summary of the invention:

The purpose of this utility model is: provide that a kind of easy construction, cost are lower, the effect that intercepts water intercepts water french drain preferably, to solve the deficiencies in the prior art.

The utility model is to constitute like this: the cross sectional shape of the french drain that intercepts water (1) is up big and down small trapezoidal, promptly intercept water two lateral sulcus walls of french drain (1) for facing upward oblique lateral sulcus wall (2) and (3) respectively round about, and on lateral sulcus wall (2) and bottom of trench (4), be provided with the antiseepage section bar bed of material, and the lateral sulcus wall of lateral sulcus wall (3) for using infiltration section bar material to make.In the french drain that intercepts water (1), place the sandstone material that bulk or coarse granule shape can be permeable.

Owing to adopted will the intercept water cross sectional shape of french drain (1) of technique scheme, the utility model to be made into up big and down small trapezoidally, be about to two lateral sulcus walls (2) and (3) for distinguishing inclined in opposite directions, like this, the stress condition of furrow bank is good, and construction is easy, and cost is low.The lateral sulcus wall (3) of french drain (1) of intercepting water uses infiltration section bar material to make, and the underground water of upstream can successfully be entered in the french drain that intercepts water (1); The intercept water opposite side furrow bank (2) of french drain (1) and bottom of trench (4) gone up and used the water proof type material to make, and stops the underground water of the french drain (1) that intercepts water to enter ground under electrolytic cell and the bus basis.Convenient construction so not only, but also reduced cost, and improved the transmissibility of french drain widely.Therefore, the utility model compared with prior art has easy construction, cost is lower, effective advantage intercepts water.When using the utility model, the utility model is arranged on appropriate position, potroom (5) protective range upstream, and the lateral sulcus wall (2) of the use antiseepage section bar material of the french drain (1) that will intercept water making is located at the side near potroom (5), and the lateral sulcus wall (3) that the use of the french drain (1) that will intercept water infiltration section bar material is made is located at the opposite side away from potroom (5), existing like this transmissibility preferably, better waterproof is also arranged, can cut off the protective range that upstream underground water enters potroom (5) effectively, guarantee that electrolytic cell and bus basic foundation are not soaked and deliquescing by underground water, sink.

Description of drawings:

Structural representation when Fig. 1 uses for the utility model; The direction of arrow is the underground water direction in the accompanying drawing, has marked position, flooring and outdoor ground position in the accompanying drawings.

The specific embodiment:

Embodiment of the present utility model: when making intercepts water french drain, the cross sectional shape of its french drain that intercepts water (1) is made into up big and down small trapezoidal, two the lateral sulcus walls of french drain (1) of being about to intercept water are made as faces upward oblique lateral sulcus wall (2) and (3) respectively round about, and a lateral sulcus wall (2) of the french drain (1) that will intercept water and bottom of trench (4) use antiseepage section bar material to make, its opposite side furrow bank (3) is made of infiltration section bar material.Its antiseepage section bar material and infiltration section bar material all can adopt the finished material of selling on the market in the prior art.If be provided with when intercepting water french drain in appropriate location, upstream, electrolysis production workshop (5), french drain (1) the bottom of trench absolute altitude that preferably intercepts water is lower than the electrolytic cell and the bus basis absolute altitude of potroom (5); The end face absolute altitude of furrow bank (2) and (3) is higher than underground water end face absolute altitude, and in a lateral sulcus wall (2) employing antiseepage section bar material making near potroom (5), and adopting infiltration section bar material to make away from the opposite side furrow bank (3) of potroom (5), the underground water that adopts the suitable gradient that the french drain (1) that intercepts water is collected bottom of trench (4) is discharged to beyond potroom (5) protective range or in plant area's drainage pipeline networks simultaneously.The ground that can prevent electrolytic cell and bus basis so effectively is subjected to underground water immersion deliquescing and causes immerge.

Claims

1. french drain that intercepts water, it is characterized in that: the cross sectional shape of the french drain that intercepts water (1) is up big and down small trapezoidal, promptly intercept water two lateral sulcus walls of french drain (1) for facing upward oblique lateral sulcus wall (2) and (3) respectively round about, and on lateral sulcus wall (2) and bottom of trench (4), be provided with the antiseepage section bar bed of material, and the lateral sulcus wall of lateral sulcus wall (3) for using infiltration section bar material to make.
