Description
Technical field
Mineral Engineering tunnelling is constructed.
Background technology
If non-perpendicular relation, one wait dig tunnel with one dug tunnel it is mutually saturating when, roadway's sides to be dug are not
Can simultaneously with dig tunnel mutually thoroughly, but a gang of elder generation is thoroughly, and another side is still in tunneling construction.When it is a gang of thoroughly,
When another side is still in tunneling construction, saturating mouth base plate is one fan-shaped.The covering of the fan gradient had both been not equal to has dug tunnel slope
Degree, is also not equal to tunnel to be dug.
Accurately determine that the mouth covering of the fan gradient is to maintain the smooth key of covering of the fan base plate, and laying track, installation
The premise of belt.Track and belt are the most important parts of underground transport system.Keep transportation system smooth
It is one of key factor of downhole safety production to lead to without hindrance.
In real work, it is determined that the stringcourse of mouth covering of the fan has two methods, but existing defects thoroughly.One be due to
A gang of the covering of the fan gradient does not hang stringcourse thoroughly, only determines the covering of the fan gradient with ocular vision, and the collimation error causes bottom
The gradient of plate covering of the fan is inconsistent, makes troubles to laying track and driving.Two is to calculate the gradient by absolute altitude to hang
Stringcourse, as error is inevitably present in rotating detection process, base plate covering of the fan gradient stringcourse is inaccurate existing
As happening occasionally.There is not scientific factors, particularly first method and have larger qualitative property in two methods
Matter rather than quantitative property.
The content of the invention
The gradient of tunnel intersection base plate is calculated mathematically.Formula is
γ=arctan (tan α/cos θ).Stringcourse is hung by gained is calculated, bottom board slope is controlled.
The gradients of the γ for intersection's base plate covering of the fan；The α is to dig roadway gradient；The β is to treat
Pick roadway gradient；The θ is tunnel to be dug and the angle for digging tunnel.
The advantage of methods described is to calculate simple, accurate, and formula has universality, for special circumstances (two
Bar tunnel is vertical) still it is suitable for.
Description of the drawings
In order that present disclosure is easier to be clearly understood, be established below dig tunnel and tunnel to be dug it
Between geometric space relation.Wherein
Fig. 1 (a) is tunnel to be dug and the spatial relationship plan view for digging tunnel, and shade is saturating mouth covering of the fan.
Fig. 1 (b) is tunnel to be dug and the spatial relationship top view for digging tunnel, and shade is saturating mouth covering of the fan base plate.
Fig. 2 (a) be dug roadway gradient >=wait dig roadway gradient when tunnel dig with dig tunnel space pass
The solid geometric pattern of system.
Fig. 2 (b) is to have dug roadway gradient ＜ tunnels to be dug when roadway gradient is dug to close with the space for digging tunnel
The solid geometric pattern of system.
The mark of accompanying drawing 2 is expressed as：ABCD- horizontal planes；OFGC- has dug roadway floor；KJOFP-
Roadway floor to be dug；The saturating mouth covering of the fans of OPF-；α-dug roadway gradient；β-roadway gradient to be dug；γ-
The saturating mouth covering of the fan gradient；θ-tunnels included angle.
Embodiment
With reference to accompanying drawing, the invention will be further described.The method comprising the steps of：
A () has been dug gradient α in tunnel by existing map data or actual measurement；Survey tunnel to be dug with
Pick tunnel mutually thoroughly before tunnel to be dug gradient β；Calculate or measure tunnels included angle θ.
B () derives computing formula in two kinds of situation.
1. dig roadway gradient α >=situation when roadway gradient β is dug and see Fig. 2 (a), tunnel intersection bottom
The formula proving process of plate gradient γ is as follows：
In ∵ Rt Δ OEF, EF=EOtan α
In ∵ Rt Δ OPE, PE=EOcos θ
In ∵ Rt Δ PEF, tan γ=EF/PE=EOtan α/EOcos θ=tan α/cos θ
∴ γ=arctan (tan α/cos θ)
2. the situation for having dug roadway gradient α ＜ roadway gradient β to be dug is shown in Fig. 2 (b), tunnel intersection base plate
The formula proving process of gradient γ is as follows：
In ∵ Rt Δ OEF, EF=EOtan α
In ∵ Rt Δ OPE, PE=EOcos θ
In ∵ Rt Δ PEF, tan γ=EF/PE=EOtan α/EOcos θ=tan α/cos θ
∴ γ=arctan (tan α/cos θ)
It can be seen that the computing formula of two kinds of situation derivations is the same.
C () calculates the gained gradient by (b) and carries out roadway floor construction to intersection's base plate covering of the fan extension stringcourse.
Claims (2)
1. a kind of method of control tunnel intersection bottom board slope, it is characterised in that：By digging roadway gradient
α and the angle theta in tunnel and tunnel to be dug is dug and has calculated gradient γ of tunnel intersection base plate.Computing formula
For γ=arctan (tan α/cos θ).Stringcourse is hung by gained is calculated, the construction of bottom plates gradient is controlled.
2. method according to claim 1, it is characterised in that：Gradient γ of tunnel intersection base plate with
Roadway gradient β to be dug is unrelated.
