Embodiment 1

[0025] An example of the present invention is figure 1 as shown, figure 1It is a schematic cross-sectional structure diagram of a prefabricated bamboo composite pipe gallery. The section of the pipe gallery is circular and is formed by connecting several sections of prefabricated pipe joints. The pipe joint includes a pipe body 1 , a load-bearing member 2 , a vertical support beam 3 , a horizontal support beam 4 and a pipe support 5 . The radial direction of the pipe body 1 from inside to outside is an inner lining layer 11, a structural layer 12 and an outer protective layer 13. Both the inner lining layer 11 and the outer protective layer 13 are used to protect the structural layer 12, so that the pipe body 1 is waterproof and seepage-proof Leakage, corrosion resistance, prolong service life, the structural layer 12 is the main reinforcement structure of the pipe body 1. The inner liner 11 includes a flame-retardant resin and a flame-retardant fabric. The flame-retardant r...

Embodiment 2

[0027] An example of the present invention is figure 2 as shown, figure 2 It is a schematic cross-sectional structure diagram of a prefabricated bamboo composite pipe gallery. In this embodiment, the structural layer 12 also includes a sand glue layer 14 mixed with mineral sand and resin, and the sand glue layer 14 is located between the bamboo strip layers. The sand glue layer 14 is sandwiched between the bamboo strip layers, which can increase the rigidity of the pipe body 1 . Others are the same as embodiment 1.

[0028] The prefabricated bamboo composite pipe gallery described in Examples 1-2 of the present invention is made of bamboo, which is green and environmentally friendly, with renewable resources and low material cost. The prepared pipe gallery has high strength, light weight, good leakage resistance, and shock resistance. Strong, high production efficiency, convenient construction.

Embodiment 3

[0030] A method for making a prefabricated bamboo composite pipe gallery. First, a pipe body 1 of a pipe joint is prepared. The preparation method of the pipe body 1 includes the following steps:

[0031] (1) Preparation of the inner lining layer 11: the flame-retardant fabric ( Such as non-woven fabrics, knitted felts, mesh cloth, etc.) are wound on the pipe mold with several layers, and the inner lining layer is formed after curing; the specific operation in this embodiment is as follows: take the flame-retardant epoxy resin and add it in proportion to curing agent, mix evenly, then take a flame-retardant glass fiber knitted mat and soak it with the prepared resin, wind it on the pipe mold, wrap it in two layers, and then solidify it to form the inner lining layer 11 after curing;

[0032] (2) Prepare the structural layer 12: make the bamboo strips into a continuous shape (for example, the bamboo strips can be closely arranged in parallel rows, arranged in multiple rows alon...

Abstract

The invention discloses a prefabricated bamboo composite pipe gallery, which is formed by connecting a plurality of prefabricated pipe joints, wherein each pipe joint comprises a pipe body, a force bearing mechanism, vertical supporting beams, a horizontal supporting beam and pipeline supports; the pipe body radially comprises a liner layer, a structure layer and an outer protection layer from inside to outside in sequence; the liner layer comprises flame-retarded resin and flame-retarded fabrics; the structure layer at least comprises a plurality of bamboo skin layers which are bonded with water soluble resin; the outer protection layer at least comprises flame-retarded resin; and the force bearing mechanism is fixed to the inner surface of the pipe body. The invention also discloses a method of manufacturing the prefabricated bamboo composite pipe gallery. The method comprises the manufacturing of the pipe body. The preparation method of the pipe body comprises the steps: (1) the liner layer is manufactured; (2) the structure layer is manufactured; and (3) the outer protection layer is manufactured. According to the invention, bamboo is utilized to manufacture a prefabricated pipe gallery, so that the intensity is good, the weight is light, the cost is low, the impermeability is good, the antiknock characteristic is strong, the construction is convenient, and the technical problems that the existing comprehensive pipe gallery consumes too many materials, the construction project amount is large, the construction period is long and the construction cost is high are solved.

Description

technical field [0001] The invention belongs to the field of municipal facilities, in particular to a prefabricated bamboo composite pipe gallery and a manufacturing method thereof. Background technique [0002] The comprehensive pipe gallery is a municipal facility built underground for the laying of municipal pipelines. It integrates various municipal pipelines such as electric power, communication, radio and television, gas, water supply and drainage, heat, etc., effectively uses the space under the road, saves underground space resources, and also prevents the irregular excavation of various professional pipelines, which will cause serious damage to the road. The impact caused by traffic and the surrounding environment has completely solved the problems of "zipper on the road" and "spider web in the sky". [0003] At present, whether it is cast-in-place or prefabricated, most of the integrated pipe gallery adopts reinforced concrete structure, but this structure has poo...
