Embodiment Construction

[0012] The present invention will be further described in conjunction with examples.

[0013] A preparation method for a reinforced concrete pipe jacking with a PVC sheet, comprising the following steps:

[0014] (1), adopt the hanging roller method to make the base blank of pipe jacking in the pipe mold of pipe jacking;

[0015] (2) Feed the fine aggregate into the base base, and continue to use the suspension roller method, the suspension time is 1 to 3 minutes, and form a concrete fine aggregate layer on the inner wall of the base base, and the fine aggregate layer and the base base The thickness ratio is 20:100, and the fine aggregate in the fine aggregate layer includes 50 parts by weight of water, 100 parts by weight of cement, 80 parts by weight of medium sand, and 30 parts by weight of lime;

[0016] (3) The pipe mold is carried by the hosting machine and the pipe mold is rotated in the circumferential direction. The linear speed of the pipe mold is 20 m / min, and the ...

Abstract

The invention discloses a manufacturing method of a reinforced concrete jacking pipe with a PVC sheet. The manufacturing method includes the following steps that (1) a roller overhang method is adopted for manufacturing a base blank of the jacking pipe in a pipe die of the jacking pipe; and (2) fine aggregate is fed into the base blank, and an overhang roller is continuously used. By means of the above method, at the moment that the reinforced concrete fine aggregate is in the damp state and drying is not carried out yet, the pipe die rotates in the circumferential direction, vibration rolling is carried out on PVC materials, and vibration rolling has the effect of mud extracting so as to soften a reinforced concrete fine aggregate layer and the inner wall of the base blank, fixing lugs of the PVC sheet are conveniently drilled into the reinforced concrete fine aggregate layer and the inner wall of the base blank, and the positions between adjacent fixing lugs are filled with reinforced concrete; and in this way, the PVC sheet and the reinforced concrete fine aggregate layer are easily attached, so that the PVC sheet is sequentially lined on the inner wall of the reinforced concrete fine aggregate layer from the head end to the tail end.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a method for preparing a reinforced concrete pipe jacking with a PVC sheet. Background technique [0002] Now, with the rapid development of the national economy and the great investment in infrastructure construction, the amount of pipe jacking is increasing. At present, the hanging roller method is generally used to produce reinforced concrete pipe jacking at home and abroad. The method for producing reinforced concrete pipe jacking is currently unable to embed PVC sheets in the base blank of pipe jacking. Therefore, how to closely fit and fix the inner wall of the base blank of PVC sheet pipe jacking is an urgent problem to be solved in the cement products industry. . Contents of the invention [0003] The object of the present invention is to provide a preparation method for reinforced concrete pipe jacking with PVC sheet, which solves the problem that th...
