Technical Field

The utility model belongs to the technical field of municipal administration underground infrastructure, concretely relates to underground utility tunnel's connection structure.

Background

The underground comprehensive pipe gallery is used as an important city infrastructure, and the continuous length is very large. The utility tunnel generally adopts the concrete as raw and other materials, consequently needs to set up the movement joint. The processing of the movement joint of current utility tunnel generally adopts the rod iron of fat liquoring to connect in movement joint department: as shown in fig. 1, spaces for a plurality of steel bars are reserved when concrete is poured, and the steel bars are inserted along the longitudinal direction of the comprehensive pipe gallery after the concrete is made; the steel bar can move properly in the horizontal direction, and belongs to flexible connection; the device is immovable in the vertical direction and belongs to rigid connection; and the steel bar is used as a shear-resistant member of the deformation joint connecting part.

But because the outside of utility tunnel all has the compaction soil layer all around, therefore if the rod iron receives destruction, the utility tunnel local settlement deformation that arouses in movement joint department can not the performance very obvious, also difficult observation. And the settlement dislocation that arouses transmits on the inside pipeline of utility tunnel, will lead to utility tunnel's waterproofing membrane to be torn, and then leads to whole utility tunnel waterproof failure, influences utility tunnel's safe operation. And the rod iron is buried inside the concrete of utility tunnel, even if subside has taken place, also is difficult to the restoration processing in the later stage.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a connection structure of utility tunnel underground is provided, can be convenient for observe and maintain utility tunnel's settlement dislocation through this connection structure, the initial stage that takes place to subside relatively at the movement joint can carry out effective processing to the movement joint, and then maintains utility tunnel's safe operation.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, fig. 2, fig. 3 and fig. 3, the utility model discloses a connection structure of utility tunnel, including utility tunnel body 1, be provided with a plurality of coupling assembling in utility tunnel body 1's movement joint department, all coupling assembling are arranged along utility tunnel body 1's cross-section circumference equipartition. In the scheme, the connecting assembly comprises a steel strip 3 and a plurality of anchor bolts 4. Spout 31 has all been seted up at the both ends of steel strip 3, and the long direction of spout 31 is unanimous with utility tunnel body 1's axial. Both sides all are provided with the anchor bolt hole around the movement joint, and this anchor bolt hole can reserve, also can punch at the later stage and bore and get in the concrete pouring. The anchor bolt holes correspond to the sliding grooves 31 in the radial direction of the section of the comprehensive pipe gallery body 1. As shown in fig. 3, in the preferred embodiment, each runner 31 corresponds to two anchor bolts 4, i.e. one runner 31 corresponds to two anchor bolt holes. The steel plate strip 3 and the axial direction of the comprehensive pipe gallery body 1 form an inclination angle of 45 degrees. After the anchor bolts 4 penetrate through the two sliding grooves 31 on the steel plate strip 3, the anchor bolts 4 are continuously anchored into the anchor bolt holes on the two sides of the deformation joint. Both ends of the steel plate strip 3 are respectively fixed with the front side and the rear side of the deformation joint through anchor bolts 4, and the steel plate strip 3 is fixed on the inner wall of the comprehensive pipe gallery body 1. Simultaneously, utilize the lath 3 to maintain the movement joint state, prevent that utility tunnel from producing at movement joint department and subsiding the dislocation.

As shown in fig. 3, an optimization is also given in the optimized embodiment for the connection structure of the anchor bolt 4 and the utility tunnel body 1. When pouring the concrete of utility tunnel body 1, bury pre-buried steel sheet 5 in utility tunnel body 1 in advance to weld two sleeves 6 on pre-buried steel sheet 5, the axial perpendicular to pre-buried steel sheet 5's of sleeve 6 face, also the radial setting of cross-section along utility tunnel body 1 of sleeve 6. After the anchor bolt 4 runs through the sliding groove 31, the anchor bolt can be fixed with the sleeve 6, so that the force transmission mode between the anchor bolt 4 and the concrete of the comprehensive pipe gallery body 1 becomes more uniform. The method does not damage the concrete and is more beneficial to maintaining the integral integrity of the concrete. And through the connection of sleeve 6 and pre-buried steel sheet 5, this kind of method is more effective to preventing that crab-bolt 4 from taking place to cut the perk destruction, simultaneously can save material, and finally, compare and place sleeve 6 alone, this kind of method can avoid sleeve 6 to take place relative displacement under the temperature stress effect. Simultaneously because the lifting surface between pre-buried steel sheet 5 and utility tunnel body 1 is great, can effectively resist the pulling force of sleeve 6, make crab-bolt 4 can be more firm realize fixed connection with utility tunnel body 1, and then make the connection between 3 of steel sheet strip and the utility tunnel body 1 more firm.

In the scheme, in order to prolong the service life of the steel plate strip 3: the steel plate strip 3 is sleeved with a double-layer plastic film. Can stop like this to corrode 3 steel sheet strips through the sewage of utility tunnel body 1, and then make 3 steel sheet strips corroded the destruction as early as possible. The double-layer plastic film has a better protection function. For the structural design of the existing comprehensive pipe gallery body 1, the length of the sliding groove 31 is set to be 3cm, the sliding groove 31 with the size accords with the connection design of most existing general grid pipe gallery bodies through design calculation, and further design optimization of an operator is avoided. As shown in fig. 4, two end faces of the steel strip 3 in the present case adopt the structure of the arc chamfer, and compared with the steel strip 3 adopting the rectangular structure, the arc chamfer can effectively prevent the end part of the steel strip 3 from scratching the inner wall of the utility tunnel body 1, and has a certain protective effect on the utility tunnel body 1.

The implementation principle of the scheme is as follows: among the prior art, the fat liquoring steel sheet is the inside of embedding in utility tunnel body 1, when consequently scribbling 2 destroys of rod iron, hardly thought to observe, and in case the displacement joint department takes place to subside the dislocation, then will arouse 1 waterproof failures of utility tunnel body, is difficult for changing and restoreing scribbling rod iron 2 moreover. In the scheme, the steel plate strips 3 and the anchor bolts 4 are exposed on the inner wall of the comprehensive pipe gallery body 1, so that the steel plate strips 3 can be observed manually frequently, the uneven settlement of the structure belongs to a long process, and if damage occurs, the anchor bolts 4 can be detached and the damaged or deformed steel plate strips 3 can be replaced. The uneven settlement is still acted on the utility tunnel body 1, but the newly-replaced steel plate strip 3 of the utility tunnel body 1 can continuously provide continuous resistance, can continue to guarantee that the uneven settlement is in the allowed range, and waterproofing membrane also can not be torn simultaneously, and the integrality of whole structure is still better, and the pipeline of inside is still protected fine, and this embodies the "recoverability" of structure.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
