Description
Technical field
The present invention relates to frozen construction law technology field, it is specifically related to a kind of tunnel steel tube curtain interior abnormity freezing apparatus.
Background technology
The name that applicant applies on the same day is called in " in big cross section tunneling tunnel steel tube curtain frozen construction method " and discloses a kind of constructional method for large cross-section tunnel, wherein before constructing tunnel, two active wells are offered in construction place at the two ends in tunnel, multiple push pipe is offered at tunnel perimeter to be onstructed by push bench, material is thus formed the tunnel steel tube curtain that structural strength is very high, big for guaranteeing section size, the stability of the tunneling constructing tunnel that length size is big, lead in push pipe into freezing pipe, freezing pipe is connected with extraneous refrigeration equipment, then by top casing pack concrete, push pipe is made to form meat or fish concrete steel post, when leading to into refrigerant, be filled with concrete push pipe can implement fast the ground body to push pipe inwall place freeze operation, be filled with so concrete push pipe just define freeze supervisor, but the length in tunnel is longer, for convenience of the maintenance in push pipe, can not by filling concrete in each push pipe, therefore when concrete stuffing operation, it is all refill concrete every a push pipe, but, existing freezing pipe cross section mostly is circular, if not filling concrete in push pipe, freezing pipe when lead to into the freezing efficiency of many places push pipe when refrigerant very limited, cannot be formed and freeze freezing the auxiliary of supervisor.
Summary of the invention
It is an object of the invention to provide and a kind of strengthen in the tunnel steel tube curtain with push pipe inner surface heat exchange efficiency abnormity freezing apparatus, can assist and freeze freezing of supervisor.
For achieving the above object, the technical solution used in the present invention is: abnormity freezing apparatus in a kind of tunnel steel tube curtain, comprise the steel tubing in different shapes abutting in and being arranged on push pipe inwall place, the overall structure triangular in shape of the cross-sectional shape of described steel tubing in different shapes, the length direction of steel tubing in different shapes is parallel with the length direction of push pipe and side plate face and the laminating of push pipe inwall, and the two ends of described steel tubing in different shapes are respectively arranged with refrigerant inlet and are connected with refrigerant inlet with the refrigerant exit of refrigeration plant respectively with refrigerant exit.
Compared with prior art, the technique effect that the present invention possesses is: the cross-sectional shape of steel tubing in different shapes is arranged to trilateral, utilize the one side of trilateral and the hole wall laminating of push pipe, thus increase the contact area of steel tubing in different shapes and push pipe to the full extent, increase heat exchanger effectiveness, thus can the frozen construction freezing to be responsible in liaison tunnel steel pipe curtain, realize water shutoff and strengthening action, this kind of special-shaped freezing apparatus simultaneously, it is not necessary to use concrete that steel pipe curtain is carried out filling, personnel can be facilitated to carry out monitoring and overhauling.
