Embodiment Construction

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

[0013] A preparation method for reinforced concrete pipe jacking, 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 20 parts by weight of lime;

[0016] (3) The pipe mold is carried by the hosting machine and the pipe mold is rotated circumferentially. The linear speed of the pipe mold rotation is 10 m / min, and the PVC sheet is vibrated and...

Abstract

The invention discloses a preparation method of a reinforced concrete jacking pipe. The preparation method of the reinforced concrete jacking pipe comprises the following steps that (1) a base billet of the jacking pipe is prepared in a jacking pipe die through a suspended rolling method; and (2) fine aggregate is fed into the base billet, and suspended rolling is continuously adopted. By adoption of the preparation method, the jacking pipe die is made to circumferentially rotate when a fine concrete aggregate layer is still in a humid state before being dried, vibration rolling is conducted on PVC products and has an effect of paste lifting, the inner wall of the fine concrete aggregate layer and the inner wall of the base billet are softened, fixing lugs of the PVC sheet products can be drilled into the inner wall of the fine concrete aggregate layer and the inner wall of the base billet conveniently, and the spaces between the adjacent fixing lugs are filled with concrete, so that the PVC sheet products are attached to the fine concrete aggregate layer easily, and the inner wall of the fine concrete aggregate layer can be lined with the PVC sheet products sequentially end to end.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a method for preparing reinforced concrete pipe jacking. 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 purpose of the present invention is to provide a method for preparing reinforced concrete pipe jacking, which solves the problem that the inner wall of the base blank of the PVC sheet...
