Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] The structure of a self-pressurized fast permeable prefabricated pile device of the present invention is as follows: Figure 1-3 shown.
[0034] The fast permeable prefabricated pile device can be prefabricated tubular or square, and the length is the same as that of conventional prefabricated pipe piles or square piles, and can be used for supporting construction with conventional prefabricated pipe piles or square piles. The fast permeable prefabricated pile device is composed of top plate 1, bottom plate 3, ribbed steel pipe 4, cavity and reinforced concrete permeable structure 8, etc. The cavity is filled with three-dimensional porous material 6, and the reinforced concrete permeable structure 8 is provided with water filter 2 The anti-filter layer 7 is lined with geotextile, and the ribbed steel pipe 4 is provided with stiffeners 5 .

The invention discloses a self-pressurization rapid-permeating precast pile device and a construction method thereof. The device comprises a top plate, a bottom plate, a ribbed steel pipe and a reinforced concrete permeable structure. The reinforced concrete permeable structure is arranged outside the ribbed steel pipe in a sleeving manner. The top plate and the bottom plate are fixed to the two ends of the precast pile device, and through holes communicated with the ribbed steel pipe are formed. A gap is reserved between the ribbed steel pipe and the reinforced concrete permeable structure to form a cavity. The cavity is filled with a three-dimensional cellular material, a water filtering opening is formed in the reinforced concrete permeable structure, and the interior is lined with a geotechnical cloth inverted filter layer. A hole is formed in the top plate of the precast pile device to be connected with a roof drainage system. The self-pressurization rapid-permeating precast pile device and the construction method are applied to sponge city construction, permeating of rainwater to the soil body can be accelerated, and the finial aim is to leave the rainwater in the soil body as much as possible and as faster as possible. The construction method is simple, convenient and feasible, and can be applied and popularized to residence, public building and structure building.
Description
technical field [0001] The invention relates to a self-pressurized and fast permeable prefabricated pile device and method, which belong to the construction technology category in the field of civil engineering, and are mainly used in the construction of urban sponge cities to accelerate the penetration of rainwater into the soil. Background technique [0002] In the past urban construction, the basic concept of rainwater control was "quick drainage" and "end concentration". And this approach is an important reason for urban waterlogging. A large amount of rainwater is drained away, and the rough pipe system is generally used to realize the collection of rainwater and the centralized discharge nearby. In the event of heavy rain, a large amount of rainwater runoff and the pollutants it carries will be transported to the end of the pipeline in a short period of time, resulting in an increased risk of waterlogging in the downstream area. [0003] In fact, if most of the rainw...
