preparation example Construction

[0031] The preparation method of the wall board is: use a thermosetting polyurethane board as the middle layer, respectively use glass fiber cloth as the outer layer, and use a cement board as the inner layer. The glass fiber cloth and the cement board are compositely fixed on the outer large surface and the inner large surface of the thermosetting polyurethane board respectively.

[0032] An embodiment of a pipe gallery unit structure of the present invention figure 2 , the lower side of the longitudinal steel structure polyurethane wall panel 1 has an insertion groove 2; There are insertion grooves 2 respectively, and the means of the longitudinal steel structure polyurethane wallboard 1 is inserted into the insertion groove 2, and the insertion groove 2 at the lower end is matched with the insertion convex falcon 3. There is sealant in the insertion groove 2 .

preparation Embodiment 1

[0034] 17 parts of toluene diisocyanate, 100 parts of polyadipate diisocyanate, 10 parts of 3,3'-dichloro-4,4'-diaminodiphenylmethane (Moka), glass fiber (length 1-1.5mm ) 2 parts, defoamer 2 parts, stir evenly, and solidify at 100 ℃ to make a plate.

preparation Embodiment 2

[0036] 15 parts by mass of toluene diisocyanate, 110 parts by mass of polyadipate diisocyanate, 8 parts by mass of 3,3'-dichloro-4,4'-diaminodiphenylmethane, 3 parts by mass of glass fiber and 1 part by mass of defoamer are mixed together, stirred evenly, cured at 105°C, and made into a plate;

Abstract

The invention discloses a steel-structure-polyurethane-material underground pipe gallery or working well. The steel-structure-polyurethane-material underground pipe gallery or working well comprises pipe gallery units. Each pipe gallery unit is defined by steel-structure polyurethane wall plates. Each steel-structure polyurethane wall plate comprises two wall plate bodies arranged in parallel, wherein a steel structure is located between the two wall plate bodies, and the portion, on the periphery of the steel structure, between the two wall plate bodies is poured with polyurethane concrete. Two end openings of the one or more pipe gallery units are plugged to form the steel-structure-polyurethane-material underground working well. The multiple pipe gallery units are connected end to end to form the steel-structure-polyurethane-material underground pipe gallery. Intensity is higher, installing and construction are more convenient and rapider, the water resistance is better, the service life is longer, and the multiple purposes are achieved.

Description

technical field [0001] The invention relates to an underground pipe gallery or well, and the underground pipe gallery is also called an underground tunnel. Background technique [0002] Nowadays, most of the underground pipe corridors (tunnels) are used for electric power. Because the management property right is the power distribution company, only cables can be laid, and the production process is reinforced concrete. The excavation area of ​​reinforced concrete project is large, the construction period is long, and the waterproof construction is too difficult. In addition, most of the strong and weak currents are pipes. The construction of pipes is easy to be accidentally dug and damaged, and the phenomenon of cable digging often occurs. In addition, if a section is laid in the middle of the pipe, the pipes on both sides are basically useless. If other pipelines are replaced, they cannot be excavated because they are basically buried underground. [0003] The main disadv...
