The invention relates to a manufacturing method of a rubber and chemical fiber synthetic waterproof sheet and a product thereof, and the rubber and chemical fiber synthetic waterproof sheet is formed by compounding three layers of material, wherein the middle layer is a chemical fiber cloth or felt composite layer, and the chemical fiber cloth or felt composite layer is a waterproof layer enabling polymer synthetic rubber composite material and chemical fiber cloth or felt to infiltrate and adhere mutually; when in manufacturing, the chemical fiber cloth or felt of the middle layer is firstlyplaced in a dip coating groove for enabling the chemical fiber cloth or felt to soak polymer synthetic rubber waterproof rubber material, and the middle sheet layer is further manufactured; and two layers of the chemical fiber cloth or felt are stuck on two surfaces of the middle sheet layer respectively, thereby forming the three-layer compound synthetic waterproof sheet. The polymer synthetic rubber waterproof rubber material takes rubber as main material, and a high polymer and other auxiliary materials are added for manufacturing the waterproof rubber material; the auxiliary materials comprise an accelerant, filling material, a softener, a cross-linking agent or an anti-aging agent; and the middle sheet layer can be manufactured by one of three forms respectively, namely the cold working method, the hot working method and the rolling method.

The invention discloses an assembly construction method for PVC wire pipe hidden lying, which comprises the following steps that: (1) standard bellows and direct heads are pre-manufactured in batch in advance; (2) according to markers for a shop drawing, the positions of a switch, a socket and a lamp cap box are marked on a template, and the directions of conduits are marked by arrows; (3) one end of each elbow extends out of a floor, a conduit plug is used for sealing the pipe end of the end, and a clamp is used for fixing and positioning the elbow; a point positioning joint is fixed on a positioning point at a temperature marking position, and the direct head is sleeved on the point positioning joint and positioned; the lamp cap box is installed; the lamp cap box is arranged at a lamp cap box marking position and fixed; and (4) piping: a PVC wire pipe and the direct head are respectively connected with the elbows at all positioning parts, the lamp cap box and the direct head at the positioning point. The assembly construction method for PVC wire pipe hidden lying has the advantages of good quality, high efficiency, material saving, environment protection, simple procedures, convenient operation and the like.

The invention relates to a prefabricated dewatering pipe pile in a building foundation pit and a method for using the same. The prefabricated dewatering pipe pile is hollow and cylindrical and includes a pipe wall and a conical pile point. The upper part of the pipe wall is arranged with a plurality of water-permeable piles at intervals. hole. A filter cartridge is provided inside the prefabricated downwater pipe pile, and the upper end of the filter cartridge is open and the lower end is closed. The method for using the prefabricated dewatering pipe piles includes the following steps in turn: (1) prefabricated prefabricated dewatering pipe piles; (2) determining the total number and arrangement spacing of the prefabricated dewatering pipe piles; (3) installing the prefabricated dewatering pipe piles, and (4) put submersible pump and water outlet pipe in the prefabricated downwater pipe pile; (5) stop submersible pump pumping, clear hole, pour cement mortar, and part of cement mortar penetrates outwards through the permeable hole and connects with all Describe the consolidation of soil outside the prefabricated downfall pipe pile. The invention shortens the construction period of the pipe well, and at the same time, the prefabricated downwater pipe pile is changed into an uplift pile, and the anti-floating performance of the prefabricated downwater pipe pile is improved.

The invention discloses a heavy-duty lining trolley of push-pull and slide-type disc buckle support, which includes a lining formwork system, a disc buckle-type full hall support, a chassis of the trolley, and a column. A screw jack is installed on the top of each column, and all the screw jacks can The lining formwork system is jointly lifted or lowered through the longitudinal beams; a number of horizontal jacking cylinders are arranged at intervals on the left and right behind the chassis of the trolley, and the rear end of each horizontal jacking cylinder is against the horizontally extending cylinder support, and the rear of the cylinder support At least two rebars are inserted into the concrete of the tunnel floor as reaction support. At the same time, the invention also discloses a lining template construction method using the above-mentioned heavy-duty lining trolley of the pushing and sliding buckle bracket. The lining trolley specially used for super-long-span tunnel lining construction can be recycled and reused to avoid time-consuming and costly re-installation after dismantling. It is safe, reliable and has a high bearing capacity.

A method for discharging water from a dam concrete placing area via a concealed pipe, comprising: arranging a primary water discharge pipe in a predetermined area to communicate the upstream and the downstream of the dam; laying secondary pipes for water discharge from the main water discharge pipe to the left side and the right side of the dam body to communicate with each dam block in the area; and connecting vertical tertiary pipes for water discharge from the secondary water discharge pipes on each dam block to communicate with each concrete placing space in the dam block. By adopting the method for discharging water from the dam concrete placing area via the concealed pipe, during the concrete pouring construction process of the dam, the embedded water discharge pipe network extends and expands to all poured concrete dam blocks with the progression of the dam body concrete pouring, thereby completely covering each new concrete pouring space within the dam area, solving the problem of large-area water deposit on the dam concrete placing area, creating a dry construction environment for concrete pouring, ensuring concrete pouring quality, reducing construction interference, and achieving civilized construction.
