Abstract
The utility model relates to a water drainage pipe and a water drainage device for carrying out soft foundation treatment through the water drainage pipe. The water drainage pipe comprises a water pipe body, a plurality of water drainage grooves are formed in the outer wall of the water pipe body in the axial direction, and the water drainage grooves are evenly arranged along the outer wall of the water pipe body in the circumferential direction in a radial mode. According to the water drainage device for carrying out soft foundation treatment through the water drainage pipe, a plurality of water permeable holes are formed in each water drainage groove in the lower portion of the water drainage pipe, a filter screen wraps the water drainage pipe, a transition light pipe section is arranged on the top of the water drainage pipe, and a water drainage hose is connected to the water drainage pipe through the transition light pipe section and is further connected with a vacuum pump. Due to the adoption of the water drainage grooves formed in the outer wall of the water pipe body in the axial direction, the water drainage speed of the water drainage pipe is improved; due to the adoption of the filter screen wrapping the water drainage pipe body, the water permeable holes can be prevented from being blocked, drainage of water in foundation soil is accelerated, solidification of a soil body is promoted, ground strength is improved, ground and foundation engineering construction carried out under natural underground water is prevented from being affected by the underground water, dry construction conditions are provided, a construction period is greatly shortened, and engineering quality is improved.
Description
Technical field
The utility model relates to a kind of gutter, and the utility model also relates to the dewatering installation that utilizes this gutter to carry out treatment of soft foundation.
Background technology
At present, when the blowing-filling sludge draining needing reinforcement, mainly utilize the method for vacuum preloading, vacuum method, when vacuumizing, successively in earth's surface sand cushion and vertical drainage passage, progressively to form negative pressure, makes to form pressure reduction between inside soil body and drainage channel, bed course, under this differential pressure action, pore water in the soil body is constantly discharged by drainage channel, thereby make soil solidifying, but its shortcoming mainly: cost is higher, time duration is long.Simultaneously, existing gutter is to be mostly in use equipped with drain hole outward at level and smooth tube wall, and be set with gauze outward at tube wall, often easily enter powder, fine sand, cause drain hole to stop up, because its transmission coefficient is lower, precipitation depth is inadequate, extended the time of draining, fail to meet the time limit of a project, meanwhile, also can affect the construction quality of engineering.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes that a kind of cost is low, the duration is short, can improve the gutter of transmission coefficient.Another technical problem that will solve of the utility model is to utilize above-mentioned gutter to carry out the dewatering installation for the treatment of of soft foundation.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of gutter, comprise water pipe body, be characterized in: the outer wall at water pipe body is provided with some rhones vertically, described rhone is radial along the outer wall of water pipe body and is circumferentially evenly arranged.
Another technical problem that will solve of the utility model is to come by the following technical programs further to realize, a kind of dewatering installation that utilizes above-mentioned gutter to carry out treatment of soft foundation, be characterized in: in the rhone of the bottom of gutter, be provided with several permeable holes, at gutter, be wrapped with screen pack, the top of gutter is provided with transition light pipeline section, gutter is connected with scupper hose by transition light pipeline section, and scupper hose is connected with vacuum pump.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and described screen pack is nonwoven.
Compared with prior art, some the rhones that the utility model utilizes gutter outer wall to arrange vertically, have accelerated the drainage speed of gutter; Utilization is wrapped in the screen pack outside gutter, avoid the obstruction of permeable hole, accelerated the drainage that base water in soil divides, impelled soil solidifying, improved foundation strength, make to be positioned at the impact that ground below natural groundwater and basic engineering construction can be avoided underground water, more dry execution conditions are provided; Utilization is arranged on the transition light pipeline section at gutter top, can also play certain vacuum seal effect.Compare with vacuum method, this equipment manufacturing cost is low, the duration is short, and has improved the quality of engineering.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model gutter;
Fig. 2 is the structural representation of the utility model dewatering installation.
The specific embodiment
, comprise water pipe body 1, at the outer wall of water pipe body 1, be provided with vertically some rhones 2, described rhone 2 is radial along the outer wall of water pipe body 1 and is circumferentially evenly arranged.
A kind of dewatering installation that utilizes above-mentioned gutter to carry out treatment of soft foundation, in the bottom of gutter rhone 2, be provided with several permeable holes 3, at gutter, be wrapped with screen pack 4, the top of gutter is provided with transition light pipeline section 5, gutter is connected with scupper hose 6 by transition light pipeline section 5, and scupper hose 6 is connected with vacuum pump.Described screen pack 4 is nonwoven.The described permeable hole 3 being arranged in rhone 2 is distributed in gutter bottom and makes progress in 50cm, and replaces gauze with nonwoven, and the phenomenon of having avoided permeable hole to be stopped up by powder, fine sand has shortened time of draining, has guaranteed the degree of depth of precipitation.Utilization is arranged on the transition light pipeline section between gutter and scupper hose, can also play vacuum-packed effect.
Claims (3)
1. a gutter, comprises water pipe body, it is characterized in that: the outer wall at water pipe body is provided with some rhones vertically, and described rhone is radial along the outer wall of water pipe body and is circumferentially evenly arranged.
2. a dewatering installation that utilizes above-mentioned gutter to carry out treatment of soft foundation, it is characterized in that: in the rhone of the bottom of gutter, be provided with several permeable holes, at gutter, be wrapped with screen pack, at the top of gutter, be provided with transition light pipeline section, gutter is connected with scupper hose by transition light pipeline section, and scupper hose is connected with vacuum pump.
3. the dewatering installation that carries out treatment of soft foundation according to claim 2, is characterized in that: described screen pack is nonwoven.
