Description

Leading-out structure of rigid pipeline of comprehensive pipe rack

Technical Field

The utility model belongs to the technical field of the technique of utility tunnel and specifically relates to when considering that the different positions of different pipe diameters of all kinds of rigid pipeline (heat supply, feedwater, gas etc.) draw forth in the utility tunnel, the structure way of drawing forth of a utility tunnel rigid pipeline that can adopt.

Background

The utility tunnel is a structure and accessory facilities which are built under the city and used for accommodating two or more types of city engineering pipelines. A municipal public tunnel is built under an urban road, various municipal pipelines such as electric power, communication, water supply, fuel gas and the like are integrated into a whole structure, and a special overhaul port, a lifting port and a monitoring system are arranged to implement unified planning, design, construction and management.

The comprehensive pipe gallery is built, so that the phenomenon of 'link pulling' in a city is eliminated, the smooth traffic is guaranteed, and the economic development is promoted; the requirement of developing and utilizing the urban underground space is met; the method is required for ensuring the safe operation of urban underground pipelines and improving the urban disaster prevention capability; is a need for improving urban environment construction. Therefore, the science and technology department, the construction department and the financial department have made intensive research and popularization on the comprehensive arrangement of the municipal pipelines as a new technology for the construction of new cities and the comprehensive transformation of old cities. Under the big background, in recent years, a large number of municipal comprehensive pipe galleries are planned or built in city construction all over the country, the development is towards networking, systematization and multistage, and the functions of the pipe gallery service land parcel are exerted to the maximum extent by utilizing the advantages of multistage.

Because utility tunnel design live time is long, the demand of drawing forth of all kinds of municipal pipeline in the corridor can be along with the development of utility tunnel institute service landmass constantly changes, especially rigid pipe, and its pipe diameter and route often change greatly, and meanwhile, the excavation of future road is avoided to an important a bit of utility tunnel construction, consequently just sets up the structure that can satisfy rigid pipe in the piping lane and draw forth the demand in the future and becomes the problem of awaiting the need to be solved promptly in the construction period.

Generally, the leading-out construction method of the rigid pipeline in the comprehensive pipe rack adopts the following two measures: (1) leading out a branch gallery; (2) and planning the pre-buried pipelines according to each municipal pipeline. Measure (1) can satisfy the demand of drawing forth of different pipe diameters of each municipal pipeline long-term and different positions, but the setting up of a corridor can increase utility tunnel's construction cost on the one hand, and on the other hand can occupy a large amount of latent layer spaces under the road, leads to the passing through of other not corridor pipelines to occupy the space beyond the red line of road. Measure (2) can satisfy the final requirement of plot development in the planning, but pipeline pipe diameter and position are along with the constantly changeable of plot actual development situation, if the pipe diameter and the position of original buried pipeline can't satisfy the demand, need lay direct buried pipeline to plot in addition.

Therefore, under the condition that the rigid pipeline can not completely determine the leading-out pipe diameter and the leading-out position in the construction period, leading-out of pipelines with different pipe diameters and different leading-out positions in a long period is guaranteed, one-time construction is achieved, the pipeline is permanently used, and the pipeline is economical and reasonable, and is a problem to be solved urgently in the construction of a comprehensive pipe gallery.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a structure of drawing forth of utility tunnel rigid conduit draws forth rigid conduit (heat supply, feedwater, gas etc.) pipe diameter and draw forth the position at utility tunnel long-term under the unable condition of confirming completely in the construction phase, can overcome traditional utility tunnel rigid conduit and draw forth that the reservation mouth can't draw forth different pipe diameter pipelines in a flexible way and can't overcome the inhomogeneous settlement of ground and cause the cracked problem of kneck very well.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a structure of drawing forth of utility tunnel rigid conduit, includes the reservation calandria that passes the corridor wall, pre-buried wall bushing in its characterized in that corridor wall, it wears to establish in the wall bushing to reserve the calandria, and it sets up detachable blind flange lid to reserve the calandria tip in the corridor to reserve the calandria, sets up the bracket outside the corridor.

Furthermore, a flange plate is arranged at the end part of a reserved discharge pipe in the gallery, when the pipe is not penetrated, a blind flange cover can be disassembled to be connected with the flange plate through bolts, and asphalt hemp thread plugs are arranged in the reserved discharge pipe; when the pipe is penetrated, the detachable blind flange cover is detached, the rigid leading-out pipeline penetrates through the reserved pipe, and the gap between the rigid leading-out pipeline and the reserved pipe is sealed by asphalt hemp threads.

Further, the inner section of the reserved pipe rack is provided with a concrete package.

The utility model discloses a reserve the calandria and jointly set up with waterproof sleeve pipe to reserve the calandria tip in the corridor and set up detachable blind flange lid, reserve the mode that the calandria below set up the bracket outside the corridor, provide a structure of drawing forth of utility tunnel rigid conduit. The advantages are that: the bracket can reduce the possibility of breakage at the intersection of the discharge pipe and the reserved opening caused by uneven settlement of the foundation; the flange closing plate can solve the waterproof problem during the period of no pipe penetration on one hand, and can be repeatedly opened when the pipe penetration is needed on the other hand; the waterproof sleeve and the reserved pipes are combined, so that pipelines with different pipe diameters can be led out in a long period; the leading-out construction method can meet the requirement that the pipe rack passing through the road is constructed together with the road in the construction period, and can simultaneously lead out rigid pipelines with different pipe diameters in different land blocks in a long term, thereby achieving one-time construction, permanent use and economy and reasonableness.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The urban underground comprehensive pipe gallery can meet the requirements of leading out different pipe diameters and positions of long-term rigid pipelines.

Fig. 1 is a schematic view of a conventional calandria extraction configuration. The traditional calandria is drawn forth the structure and is included pre-buried wall waterproof wall pipe 8, and pre-buried wall waterproof wall pipe 8 corridor outer end is connected and is reserved calandria 1, and pre-buried wall waterproof wall pipe 8 is interior to be blocked with pitch hemp 6.
