Abstract
This invention relates to tunnel. Specific to say it relates to a waterproof method that adapts to large quantity stratum non-homogeneous sedimentation or the disturbed open cut tunnel. This method sets the mid-burying stopping water band and the two-channel OMEGA stopping water band among the configuration distortion slot space. And it obligates grouting tube through the way of joint to make the effect of waterproof. The advantages are: the structure is simple, the quality is credible. It adopts the multiple defending lines as the synthesis waterproof system. When it has certain hydraulic pressure, it has the ability of adapting to larger distortion. This can make an effect of waterproof. It can combine grouting when need, this can attain the aim of sealing the whole big distorted hoop.
Description
Technical field
The present invention relates to tunnel-like, relate to a kind of waterproof construction of open trench tunnel of the adaptable for large value stratum ununiform settling or changing of the relative positions concretely.
Background technology
Ground fissure be face of land rock-soil layer under natural cause and human factor effect, produce cracking and form the phenomenon in certain-length and width crack on ground.Ground fissure is the result of multifactor stack, and in the ground fissure activity system, its origin cause of formation act as the master with natural geology, and human factor is auxilliary.The activity of ground fissure has three-dimensional deformation characteristics, shows as vertical sedimentation, horizontal stretch-draw and twisting.
Because the activity of ground fissure is a dynamic change procedure, the origin cause of formation, mechanism and type are all very complicated, and has tangible segmented activity feature according to moving towards difference, the face of land that has has obviously and appears, the tool that has is lain concealed property, to build, the destruction form of structure also has nothing in common with each other, so the method for preventing and treating of engineering also should be at the different active situation and the space exhibition step characteristic of ground fissure, segmentation is considered.
At ground fissure active situation and space exhibition step characteristic, need relevant specialities such as circuit, structure, track and waterproof to take all factors into consideration.At first structure design will adapt to its different deformation requirements, the displacement of its generation is controlled in the default position and structure, and this body structure of tunnel is not damaged.In this scope, reserve enough deformation spaces simultaneously,, and handle joint waterproofing well so that adjust track circuit.
In the construction of tunnel of prior art, the ground fissure that causes for a large amount of value stratum differential settlements or the changing of the relative positions for example at the above changing of the relative positions amount of 10mm, does not also have an efficient ways at present in that circuit, structure, track and waterproof etc. are relevant.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of waterproof construction of open trench tunnel of the adaptable for large value stratum ununiform settling or changing of the relative positions is provided, by buried water stop the setting in and two pass OMEGA waterstop, and the reservation Grouting Pipe reaches the effect of comprehensive waterproof to this structure in the mode of seam between malformation seam.
The object of the invention realizes being finished by following technical scheme:
A kind of waterproof construction of open trench tunnel of the adaptable for large value stratum ununiform settling or changing of the relative positions, the structure built by opencut method tunnel is combined by the rectangular configuration that at least two monobloc casts form, it is characterized in that seam between rectangular configuration and the structure is positioned at the ground fissure place that is caused by the stratum differential settlement or the changing of the relative positions that estimates, be provided with middle buried water stop between described structure seam, and after this waterstop, reserve Grouting Pipe in the structure of seam side.
The material of buried water stop is a steel limit rubber fastening band in described.
Be provided with two pass Ω type waterstop between described structure seam.Be reserved with Grouting Pipe in the structure of the seam side between two pass Ω type waterstop.
Advantage of the present invention is, and is simple in structure, reliable in quality, adopt the comprehensive waterproof system of multiple defence line, possess under certain hydraulic condition, adapt to the ability of moderate finite deformation amount, can play good waterproof effect, can reach the purpose of sealing whole piece large deformation ring in conjunction with slip casting in case of necessity.
Summary of drawings
Accompanying drawing 1 is structural representation of the present invention;
Concrete technical scheme
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As shown in Figure 1, label 1-13 represents respectively: middle buried water stop 1, sponge rubber fill plate 2, pre-embedded steel slab 3, the first road Ω type waterstop 4, the second road Ω type waterstop 5, back leg iron 6, pre-buried Grouting Pipe 7, pre-buried Grouting Pipe 8, acorn nut 9, bolt 10, press strip 11, pressing plate 12, seam 13.
Embodiment:
The structure built by opencut method tunnel of present embodiment is combined by the rectangular configuration that at least two monobloc casts form, wherein the seam between rectangular configuration and the structure 13 is positioned at the ground fissure place that is caused by the stratum differential settlement or the changing of the relative positions that estimates, buried water stop 1 in structure seam 13 places are provided with, and the first road Ω type waterstop 4, the second road Ω type waterstop 5, between the middle buried water stop 1 and the first road Ω type waterstop 4, reserved pre-buried Grouting Pipe 7 respectively between the first road Ω type waterstop 4 and the second road Ω type waterstop 5, pre-buried Grouting Pipe 8, can be at middle buried water stop, under the situation that the first road OMEGA waterstop lost efficacy, in limited space, form new water-proof wire by grouting filling.
Acorn nut 9, bolt 10, press strip 11, pressing plate 12 and back leg iron 6 are used for installing and fixing of Ω type waterstop 4,5.
In the material of buried water stop 1 be steel limit rubber fastening band, the steel limit of waterstop 1 end can make itself and the good interlock of concrete, but this waterstop commensurate structure deformation ability is limited.
Accompany two-layer nylon fiber layer in the first road Ω type waterstop 4, the second road Ω type waterstop 5, and the waterstop middle part length of adaptation deformability is very big, so can adapt to sizable deflection ability.The casting die system that matches with this type of Ω type waterstop utilizes lever principle, can reach the waterproof effect of sealing waterstop end well; Near the waterstop two ends a plurality of small tooths are arranged simultaneously, strengthened the sealing performance of waterstop and basal plane better; The flange of waterstop end can prevent that waterstop from bearing under the large deformation sedimentation operating mode, coming off from the casting die system in addition.
Be arranged with sand cushion at the structure built by opencut method tunnel floor.
