The utility model relates to an inspection well. The utility model relates to an inspection well, in particular to a geopolymer modular inspection well. The geopolymer modular inspection well is formed by assembling a bottom plate, two side plates, a top cover and two pipeline plates, and all the parts are independently prepared from geopolymers. One end of the side plate is inserted between the outer edge and the second isolation strip, one end of the pipeline plate is inserted between the outer edge and the first isolation strip, the bayonets are connected with the two ends of the lower halfblock in a clamped mode, and the top cover is connected with the top cover and the other end of the pipeline plate in an inserted mode. The device has the beneficial effects that the device is modularly arranged, separately produced, assembled during use and convenient to use; the geopolymer is used for replacing concrete production, is low in cost and more environment-friendly, and can be popularized on a large scale; standard modular production is achieved, and the overall production cost is greatly reduced.
