Embodiment Construction

[0013] The present invention will be further described in conjunction with examples.

[0014] A preparation method for reinforced concrete pipe jacking with fly ash added, comprising the following steps:

[0015] (1), adopt the hanging roller method to make the base blank of pipe jacking in the pipe mold of pipe jacking;

[0016] (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, 30 parts by weight of lime, 20 parts by weight of fly ash, 5 parts by weight of liquid activator;

[0017] (3) The pipe mold is carried by the hosting machine and the pipe mold is rotated circumferentially. The...

Abstract

The invention discloses a preparing method of reinforced concrete pipe jacking with coal ash, comprising the steps of (1), making base blank of pipe jacking in the pipe jacking pipe die with over hang roll method; (2), feeding fine aggregate into the base blank, and continuing to adopt overhang roll method. After adopting the methods, the preparing method invented makes the pipe die achieve circumferential rotation while the concrete fine aggregate layer is still under damp state and before drying, and implements vibration rolling for PVC material, the vibration rollingcreates syrup purifying effect, making the inner walls of concrete fine aggregate and base blank become soft, and is convenient for fastening lug of PVC sheet drilling into inner walls of concrete fine aggregate and base blank, and ensures concrete filling between the adjacent fastening lugs, in this way, PVC sheet and concrete fine aggregate is easy to fit, thereby,PVC can be lined on the inner wall of concrete fine aggregate in sequence from head end to 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 jacking pipe added with fly ash. 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 with fly ash added, which solves the problem th...
