Description

Abnormity frigo in tunnel steel tube curtain

Technical field

This utility model relates to frosting work method technical field, is specifically related to abnormity frigo in a kind of tunnel steel tube curtain.

Background technology

Entitled " frozen construction method in big cross section bored tunnel steel pipe curtain " that applicant applies on the same day discloses one For the construction method of large cross-section tunnel, wherein before constructing tunnel, at the construction at the two ends in tunnel, offer two works Make well, offer multiple push pipe by push-bench at tunnel perimeter to be onstructed, material is thus formed structural strength the highest Tunnel steel tube curtain, for guaranteeing the stability that the bored tunnel that cross dimensions is big, length dimension is big is constructed, is passed through in push pipe Freezing pipe, is connected freezing pipe with extraneous refrigeration plant, then by top casing pack concrete so that push pipe shape Become meat or fish concrete steel column, when being passed through coolant, be filled with concrete push pipe can Rapid Implementation to push pipe inwall place Rock And Soil carries out freeze operation, and the push pipe being so filled with concrete is the formation of freezing supervisor, but the length in tunnel is relatively Long, for convenience of the maintenance in push pipe, it is impossible to by filling concrete in each push pipe, therefore operate at Concrete Filled Time, it is all to refill concrete every a push pipe, but, existing freezing pipe cross section mostly is circular, if in push pipe Not filling concrete, freezing pipe freezing efficiency of many places push pipe in the case of being passed through coolant is extremely limited, it is impossible to formed The auxiliary freezing supervisor is freezed.

Utility model content

The purpose of this utility model be just to provide a kind of strengthen different with in the tunnel steel tube curtain of push pipe inner surface heat exchange efficiency Shape frigo, can assist and freeze freezing of supervisor.

For achieving the above object, the technical solution adopted in the utility model is: abnormity frigo in a kind of tunnel steel tube curtain, Including abutting in the shape tube being arranged at push pipe inwall, the overall structure triangular in shape of the cross sectional shape of described shape tube, different The length direction of type pipe is parallel with the length direction of push pipe and fit with push pipe inwall in side plate face, the two ends of described shape tube It is respectively arranged with refrigerant inlet to connect with refrigerant exit and the refrigerant inlet of refrigerating plant respectively with refrigerant exit.

Compared with prior art, the technique effect that this utility model possesses is: the cross sectional shape of shape tube is arranged to three Dihedral, utilizes the hole wall laminating of the one side of triangle and push pipe, thus increases connecing of shape tube and push pipe to the full extent Contacting surface is amassed, and increases heat exchanger effectiveness, thus can the frozen construction freezing supervisor in liaison tunnel steel pipe curtain, it is achieved water shutoff And strengthening action, the most this abnormity frigo, it is not necessary to use concrete that steel pipe curtain is carried out filling, personnel can be facilitated to enter Row monitoring and maintenance.

Detailed description of the invention

In conjunction with Fig. 1 to Fig. 5, the utility model is further described

In a kind of tunnel steel tube curtain, abnormity frigo, is arranged on the shape tube 20 at push pipe 10 inwall including reclining, described The overall structure triangular in shape of the cross sectional shape of shape tube 20, the length direction of shape tube 20 and the length direction of push pipe 10 Fitting with push pipe 10 inwall in parallel and side plate face, the two ends of described shape tube 20 are respectively arranged with refrigerant inlet and coolant Outlet connects with refrigerant exit and the refrigerant inlet of refrigerating plant respectively.

Utilize refrigerating plant to be sent to by coolant in shape tube 20, the tube section of shape tube 20 be fabricated to triangular structure, Triangle at this is not necessarily the triangle of standard, is subtriangular shape, the side plate face of triangle and top The contact internal walls face of pipe 20 is maximum, can increase to the full extent and the contact area of push pipe 20 inwall, thus can significantly carry The freeze operation to push pipe 10 is implemented in high shape tube 20 and the cold conduction efficiency of push pipe 10, and then shortest time, should Abnormity frigo can assist steel pipe inside story to freeze the frozen construction of supervisor, it is achieved water shutoff and strengthening action, the most this different Shape frigo, it is not necessary to use concrete that steel pipe curtain is carried out filling, personnel can be facilitated to be monitored and overhaul.

As preferred version of the present utility model, described in Fig. 4, described shape tube 20 includes that cross section angle is arranged Flap 21, the length direction of described flap 21 along push pipe 10 length direction lay, the biside plate of flap 21 End face is welded and fixed with the inwall of push pipe 10, and the chamber enclosed between described flap 21 and the inwall of push pipe 10 constitutes cold The tube chamber that matchmaker passes through.The flap 21 utilizing steel plate material is subjected to push pipe 10, utilizes the inwall of push pipe 10 As a part for shape tube 20, can directly make coolant and push pipe 10 contact internal walls, and then raising is frozen to the full extent The efficiency of knot.

Preferably, the bending angle of described flap 21 is 90 °.

Freezing efficiency for improve whole inlet hole 10, described shape tube 20 is positioned at push pipe 10 and is laid with multiple, special-shaped One end of pipe 20 is provided with and communicated with extension 30, described extension 30 along push pipe 10 inwall circumferentially, extension The pipe end of 30 is provided with pipe joint 31, soft by being plugged on the connection of pipe joint 31 between extension 30 and extension 30 Pipe 40 realizes connection.Utilize extension 30 can realize the circulation of the coolant in two shape tubes 20, real push pipe 10 Inside freezing the synchronization of efficiency, the extension 30 that this goes out may be used without the manufacture method of shape tube 20, shown in Fig. 5.

Further, the outer wall of described pipe joint 31 is arranged to waveform.
