Abstract
The utility model discloses a draining precast pile for road soft foundation processing, belonging to the field of highway and urban road engineering construction, and particularly relating to a pile body for soft foundation processing engineering construction. The draining precast pile body for the highway and urban road engineering construction is a concrete precast draining pile body which is formed by a pile main body and one to three multi-hole draining passages that are through longitudinally, the pile main body is a solid square pile or a tube pile, and draining troughs are arranged on the boundary surfaces of the pile main body and the multi-hole draining passages. The draining precast pile body with the design is made in the following way: pile-pressing equipment for the precast square pile or the precast tube pile is utilized to press the precast square pile or the precast tube pipe with a plastic draining plate with the multi-hole draining passages by one time, and as the pile body has a draining function, the performance of earth between piles can be improved under the draining function, therefore, the density of the draining precast pile body can be reduced, the construction time can be shortened, the construction efficiency can be remarkably improved, and the construction cost as well as the engineering cost can be saved.
Description
Technical field
A kind of draining preformed pile that is used for the road treatment of soft foundation of the utility model belongs to highway and urban road engineering construction equipment field, is specifically related to treatment of soft foundation engineering construction pile body.
Background technology
The pile body that is used for highway and urban road treatment of soft foundation at present mainly is divided into coagulation great soil group pile body and cement great soil group pile body, and wherein coagulation great soil group pile body has cast-in-place class and prefabricated class, and prefabricated class mainly comprises precast square pile and prefabricated tubular pile.
Existing precast square pile or pile tube are a kind of ripe pile bodies of quality controllable system, but if a common shortcoming is arranged as highway and urban road treatment of soft foundation, promptly do not have drain function, and use for the pile body in this field, draining has extremely important function sometimes, because as can not under the effect of draining, improving its performance, certainly will increase pile body density, and cause cost higher by inter-pile soil.Therefore, press for exploitation and be used for the pile body that highway and urban road treatment of soft foundation have drain function, to satisfy the needs of highway and urban road construction develop rapidly.
The utility model content
The purpose of this utility model provides a kind of prefabricated pile body of draining that is used for the road treatment of soft foundation, improves the inter-pile soil performance by the pile body with drain function, reducing the density that is provided with of draining preformed pile, thereby reduces construction costs under the prerequisite of ensuring the quality of products.
The purpose of this utility model is achieved through the following technical solutions:
The utility model is used for the prefabricated pile body of draining of road treatment of soft foundation, is concrete prefabricated draining pile body, and this pile body is made up of pile body main body and 1-3 porous drainage channel that vertically connects, and at the interface of pile body main body and this porous drainage channel rhone is arranged.
Described pile body main body is solid side's stake or pile tube.
The prefabricated pile body of the design's draining is the piling equipment that utilizes precast square pile or prefabricated tubular pile, by design specifications, precast square pile or prefabricated tubular pile and plastic draining board with porous drainage channel once be pressed into finish, because of its effect, make inter-pile soil under the effect of draining, improve its performance, so the density of the prefabricated pile body of draining can reduce with draining, so shorten the engineering time, and significantly improve efficiency of construction, and save operating expenses, reduce engineering cost.

The specific embodiment
The design is used for the prefabricated pile body of draining of road treatment of soft foundation, is stake of concrete prefabricated draining side or pile tube.
Be example now, further specify the utility model in conjunction with the accompanying drawings and how to implement with the draining prefabricated tubular pile:
The draining prefabricated tubular pile that is used for the road treatment of soft foundation, by this draining preformed pile design specification requirement, design a rhone 3, and a plastic draining board with porous drainage channel is embedded in the rhone 3, utilize the static pressure equipment or the vibratory equipment of prefabricated tubular pile once to be pressed into moulding, thereby form in draining prefabricated tubular pile pile body main body 1 by plastic draining board and vertically connect 1 drainage channel 2 that constitutes, there is rhone 3 at the interface of the drainage channel 2 that constitutes in pile body main body 1 with by plastic draining board.
Claims (3)
1. the prefabricated pile body of draining that is used for the road treatment of soft foundation is concrete prefabricated draining pile body, it is characterized in that this pile body is made up of pile body main body and the porous drainage channel that vertically connects, at the interface of pile body main body and this porous drainage channel rhone is arranged.
2. a kind of prefabricated pile body of draining that is used for the road treatment of soft foundation according to claim 1 is characterized in that porous drainage channel number is 1-3.
