Abstract
The invention discloses a new subaqueous tunnel or pipeline digging method, and belongs to the field of civil engineering bridge construction. The water is partitioned by using partition equipment on a route where a subaqueous tunnel needs to be dug, the middle water is pumped out, a long subaqueous zone is exposed, then a big open trench can be dug, and the tunnel is cast, or prefabricated pipes are laid in the open trench, wherein the partition equipment can be used for over two times. The construction is convenient, the project progress is quickened, and the method is easily implemented in subaqueous underground tunnels (pipelines) of shallow water areas and particularly can be used for the tunnels across the rivers.
Description
Technical field
The present invention is that method is dug in a kind of new subaqueous tunnel, belongs to civil engineering bridge road construction field.
Background technology
Present bottom cutting method all is to adopt the method for digging a hole, and this method is very traditional, but shortcoming is the method constructional difficulties of digging a hole, and programming is slower, and every day, driving had only seldom several meters.
Summary of the invention
At the tradition method constructional difficulties of digging a hole, the shortcoming that programming is slow the invention provides the new method of a cover, can reduce difficulty of construction greatly, improves programming.
Technical scheme of the present invention may further comprise the steps: 1. dig on the route of subaqueous tunnel at needs, with xegregating unit water is separated, water in the middle of finding time exposes a long water-bed area.
2. a big open drain just can be excavated in the bottom of being exposed in the middle of xegregating unit, is building the tunnel, perhaps lays prefabricated pipe in the open drain.Utilize the water xegregating unit like this,, can also construct simultaneously by sliver, both significantly reduced difficulty of construction, can increase programming greatly again just as on the level land, buying pipeline.
3. as the waters ship's navigation is arranged, can section construction.
4. if water xegregating unit isolation performance is bad, the above xegregating unit in available two roads or then add water pumper and improve pumpage.
Described xegregating unit is watertight shutter and supports cabinet that watertight shutter separates water, supports the inboard that cabinet is installed in watertight shutter, supports watertight shutter, makes watertight shutter can bear the pressure of water.
Transportable crosspiece is all arranged in the middle of the described support cabinet and bottom, can further facilitate excacation.
Outstanding advantage of the present invention:
Easy construction, programming is accelerated; In the shallow water-bed subterranean tunnel (pipeline) in waters, more easily realize, be particularly useful for the tunnel that crosses the river, river.
Description of drawings

The schematic top plan view of Fig. 2 water proof device structure
1 for supporting cabinet among the figure, and 2 is watertight shutter, and 3 is middle crosspiece.
The specific embodiment
Concrete as Fig. 1, shown in Figure 2.Dig at needs on the route of subaqueous tunnel, laying watertight shutter 2 separates water, support cabinet 1 and support watertight shutter 2, make it can bear the pressure of water, water in the middle of finding time then, expose a long water-bed area in the middle of the watertight shutter 2, just can excavate a big open drain, in building tunnel or open drain, lay prefabricated pipe.If the dash performance of one deck watertight shutter 2 is bad, can re-lay the multilayer watertight shutter.Support the bottom of cabinet 1 and have only crosspiece, do not have base plate, can slowly move down, thereby when thinking that the depths is excavated, support the position that cabinet can be supported on watertight shutter all the time along with the degree of depth of excavating.In the middle of the support cabinet 1 shown in Fig. 2 a crosspiece 3 is arranged, crosspiece 3 can move, and moves along with pushing ahead of excacation, has made things convenient for the cutting in tunnel.
Claims (4)
1. new subaqueous tunnel or pipeline are dug method, it is characterized in that:, isolate from water the place of required construction with xegregating unit, again in isolated area oprn-work, build or lay the subaqueous tunnel.
2. new subaqueous tunnel according to claim 1 or pipeline are dug method, it is characterized in that: above xegregating unit in available two roads or increase water pumper improve pumpage.
3. dig method according to claims 1 described new subaqueous tunnel or pipeline, it is characterized in that: described xegregating unit is watertight shutter and supports cabinet, supports the inboard that cabinet is installed in watertight shutter, supports watertight shutter.
4. dig method according to claims 1 described new subaqueous tunnel or pipeline, it is characterized in that: transportable crosspiece is all arranged in the middle of the described support cabinet and bottom.
