Abstract
The utility model belongs to the technical field of the shield tunnel construction, specifically disclose a shield constructs and receives with pre-buried steel ring slip casting stagnant water device, including the crown plate of locating the shield shell top, be equipped with between crown plate and the shield shell and ooze the thick liquid passageway, be equipped with out the thick liquid hole on the crown plate, go out thick liquid hole department intercommunication and have the slip casting pipe, the slip casting pipe communicates with the device of pouring into the slip casting liquid. The water injection device with the structure can solve the problems that the construction cost is increased by a freezing method and the sealing effect of the tunnel door rubber curtain and the tunnel door pressing plate is not good.
Description
Technical Field
The utility model belongs to the technical field of the shield tunnel construction, especially, relate to a shield constructs and receives with pre-buried steel ring slip casting stagnant water device.
Background
When a shield method is adopted for tunneling a tunnel, shield machine receiving is one of key processes, and particularly is a serious difficulty in risk control in a permeable stratum which is easy to generate water inrush and sand inrush. The traditional water stopping method comprises the steps of reinforcing the stratum by adopting a freezing method, or sealing the opening by adopting a tunnel door rubber curtain and a tunnel door pressing plate.
When the freezing method is adopted to reinforce the stratum, the construction period is long, the energy consumption is large, and the construction cost is greatly increased; when the tunnel portal rubber curtain and the tunnel portal pressing plate are used for sealing the tunnel portal, the sealing plate is arranged in a blocking mode, so that the water stopping effect is reduced due to gaps among plates, and the hidden danger of water leakage when the shield machine receives water is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a shield constructs and receives with pre-buried steel ring slip casting stagnant water device to solve freezing method and increase construction cost and the sealed not good problem of effect of portal rubber curtain and portal clamp plate.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a shield constructs and receives with pre-buried steel ring slip casting stagnant water device, is equipped with between ring slab and the shield shell and oozes the thick liquid passageway including locating the ring slab of shield shell top, is equipped with out the thick liquid hole on the ring slab, and it has the slip casting pipe to go out thick liquid hole department intercommunication, the slip casting pipe communicates with the device of pouring into the slip casting liquid.
The working principle of the technical scheme is as follows: pour into the slip casting liquid into in the slip casting pipe, the slip casting liquid can flow into through the grout outlet and ooze the thick liquid passageway in, under the dual function of slip casting pressure and slip casting liquid self gravity, the slip casting liquid can be gradually will ooze the thick liquid passageway and fill up to prevent gushing the emergence of the condition such as sand of gushing water.
The beneficial effects of this technical scheme lie in: compared with the prior art, the device greatly improves the sealing effect when the shield receives, and meanwhile, the device has a simple structure, is convenient to maintain, is easy to operate during construction, reduces the working period and the construction difficulty, and reduces the construction cost.
Further, the ring plate is the L shaped plate, and vertical side is equipped with the injected hole, the horizontal side of ring plate is located to the grout outlet, the injected hole and the grout outlet intercommunication are managed to the slip casting. The L-shaped plate can support the grouting pipe.
Furthermore, the included angle between the grouting pipe and the horizontal side of the annular plate is 15-60 degrees. Within the range of the included angle, the grouting effect is best.
Further, the grouting liquid is polyurethane slurry. The polyurethane slurry has good adhesive property, and can improve the sealing property of the shield.
Drawings
Fig. 1 is the utility model relates to a shield constructs receiving with pre-buried steel ring slip casting stagnant water device's cross-sectional view.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: grouting holes 1, grouting pipes 2, grout outlet holes 3, grouting liquid 4, vertical sides 5, horizontal sides 6 and shield shells 7.
The embodiment is basically as shown in the attached figure 1: the utility model provides a shield constructs and receives with pre-buried steel ring slip casting sealing device, is including being fixed in the crown plate of shield shell 7 top, and the crown plate is the L shaped plate, includes vertical side 5 and horizontal side 6. The vertical side 5 of the ring plate is provided with a grouting hole 1, the horizontal side 6 of the ring plate is provided with a grout outlet 3, a grouting pipe 2 is communicated between the grouting hole 1 and the grout outlet 3, the grouting pipe 2 is respectively welded with the grouting hole 1 and the grout outlet 3, the included angle between the grouting pipe 2 and the horizontal side 6 of the ring plate is 15-60 degrees, and the embodiment adopts 30 degrees. A permeation channel is arranged between the horizontal side 6 of the annular plate and the shield shell 7, the grouting pipe 2 is communicated with a device for injecting grouting liquid 4, and the grouting liquid 4 is polyurethane slurry in the embodiment.
The specific implementation process is as follows:
inject slip casting liquid 4 into slip casting pipe 2, slip casting liquid 4 can flow into through out thick liquid hole 3 and ooze the thick liquid passageway in, under the dual function of 4 self gravities of slip casting pressure and slip casting liquid, slip casting liquid 4 can be gradually with oozing the thick liquid passageway and fill up to prevent gushing the emergence of the condition such as water gushing sand.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
