Construction method and equipment for mounting vertical-precipitation well point pipe

Abstract

The invention discloses a construction method and equipment for mounting a vertical-precipitation well point pipe. The equipment can be called an efficient spiling machine for the precipitation well point pipe, is prepared by modifying the conventional crawler-type plastic drainage plate spiling machine, and enabling the conventional spiling machine to achieve the precipitation well point pipe spiling and digging functions, and comprises a chassis, a main frame, a winding plant, a power plant, a fixed pulley, a casing pipe, a mobile type pile shoe and a rope, wherein the main frame and the winding plant are fixedly connected with the chassis; the power plant is attached to the outer side of the main frame; the upper end of the power plant is connected with the winding plant, and the lower end of the power plant is connected with the casing pipe; the fixed pulley is arranged at the top, close to the power plant, of the casing pipe; the rope passes through the fixed pulley; one end of the rope is tied to the rear end of the well point pipe, and the other end of the rope is held by operating personnel; the mobile type pile shoe is mounted at the bottom end of the casing pipe and in an opening state or a closing state; the front end of the well point pipe to be mounted is bound with a fixed plastic blink drain, and the rear end of the well point pipe to be mounted is connected with the rope. The construction method and the equipment disclosed by the invention have the advantages of simple and efficient construction, civilization, environment-friendliness, and low cost.

Description

technical field [0001] The invention belongs to the technical field of engineering dewatering, and relates to a construction method and equipment for installing vertical dewatering well point pipes. Background technique [0002] Well point dewatering is a common technical method used in engineering dewatering, including vacuum well point dewatering, jet well point dewatering, electroosmotic well point dewatering, etc. It is mainly used in construction foundation pits, foundation treatment and other projects. [0003] The diameter of the well point pipe is mostly 42-50mm metal pipe, the length of the pipe is 6-8m, the length of the filter pipe is 1.2-2m, and the outsourcing is 1-2 layers of nylon or copper wire filter. [0004] The current construction technology of well point pipe installation is generally to use drilling rig mud wall to drill into the hole or high-pressure water impact to form the hole. After reaching the designed hole depth, increase the pump volume to flu...

Problems solved by technology

[0007] However, the above method only partially improves the hole-forming process of the dewatering well point pipe, and still does not effectively solve the problems and shortcomings of the installation process of the dewatering well point pipe, such as difficult construction, low construction efficiency, poor construction environment, high labor intensity, and high construction cost.

At the same time, problems such as sand filter gradation or uneven investment often affect the drainage effect
