Description
Technical field
This utility model belongs to building foundation pit technical field of construction, is specifically related to a kind of horizontal floral tube precipitation system.
Background technology
In hydraulic structures construction period, owing to geological condition is different, some engineering project levels of ground water are higher, when conventional relevant deep foundation base excavation construction, have a large amount of subsoil water and ooze out, and will be unable to construction as got rid of not in time.In order to solve seepage in foundation seepage problem, we used well-points dewatering and tube well dewatering method in the past, well-points dewatering and tube well dewatering are to use lower peupendicular hole pipe to carry out precipitation, it is all the soil property of sandy loam to underground, there is positive effect, but when level of ground water appears above impermeable stratum or the surface more serious geology of infiltration (such as foundry loam layer), upper strata dewatering effect is inconspicuous.Well-points dewatering and tube well dewatering are more without positive effect.In order to thoroughly solve the infiltration of foundation ditch top layer and the problem of foundation ditch side infiltration, engineers and technicians, according to conventional construction experience, consult relevant information, have developed horizontal floral tube precipitation method.Trying out in drawing yellow lock reconstruction project natural literary composition rock canal inverted-siphon engineering in Puyang canal village, obtained positive effect, indices all can reach construction requirement.This equipment use material price buying cheap, easy, low cost, construction technology is simple, dewatering effect is obvious.Improve site construction condition, striven for the engineering time, accelerate construction speed, improve economic benefit.
Utility model content
The purpose of this utility model is to provide that a kind of simple in construction, dewatering effect be good and the horizontal floral tube precipitation system of low cost.
For achieving the above object, this utility model by the following technical solutions: horizontal floral tube precipitation system, including water leg, sand bed in water leg underfill, middle sand bed is laid soil layer of holding one's breath, middle sand bed center is equipped with precipitation floral tube；Precipitation floral tube is horizontally disposed with；Precipitation floral tube one end seals, and the other end is connected on main pipeline by lateral, and main pipeline connects vacuum-dewatering equipment.
Precipitation floral tube includes plastic tube, and plastic tube is evenly equipped with through hole, is fixed with palm fibre lamella, is fixed with filter mesh layer outside palm fibre lamella outside plastic tube.
Plastic tube internal diameter is 4-5cm；Through-hole aperture is 6-10mm, and pitch of holes is 10-20cm.
Middle burial depth is 30-40cm；Described the thickness of the layer of holding one's breath is 15-30cm.
Vacuum-dewatering equipment includes the vacuum tank being connected with main pipeline, and vacuum tank connects has vacuum pump, vacuum pump to be provided with motor.
Main pipeline is arranged below pipeline support.
The processing method of horizontal floral tube precipitation system, comprises the following steps:
(1) precipitation floral tube is made；
(2) water leg is excavated at needs precipitation position；
(3) in laying bottom water leg, sand, is placed on precipitation floral tube on Shamian Island, then fills middle sand, and sand bed in formation fills, at middle sand bed top, soil layer of holding one's breath；
(4) by lateral, precipitation floral tube is connected with main pipeline；
(5) start vacuum-dewatering equipment and carry out precipitation.
Selecting internal diameter in step (1) is the plastic tube of 4-5cm, plastic tube surface drilling formed aperture be 6-10mm, pitch of holes be the through hole of 10-20cm, include that plastic tube forms palm fibre lamella with palm fibre sheet, after palm fibre lamella periphery uses tied silk colligation fixing, it is wrapped in outside palm fibre lamella with filter screen again and colligation is fixed, prepare precipitation floral tube.
One end of precipitation floral tube uses stopper to seal, and the other end connects main pipeline by lateral.
Compared with prior art, the beneficial effects of the utility model are as follows: utilize horizontally disposed precipitation floral tube to carry out precipitation, and precipitation speed is fast, efficiently solve top layer infiltration.It is horizontally disposed with precipitation floral tube the infiltration of foundation ditch side is dammed and also had the biggest effect, lateral seepage stream can be prevented；Precipitation used unit quantity is few, easy to operate；Preparing precipitation floral tube after selecting plastic tube processed, material is easy to get and expense is low；The plastic tube boring machine that internal diameter is 4-5cm is drilled to aperture be 6-10mm, pitch of holes be the precipitation floral tube of 10-20cm, simple for production；Owing to well-point dewatering method is vertical pumping, belong to deep layer precipitation, precipitation scope scalp is big, take effect slow, and be not suitable for the foundation ditch of big cross section, if dewatering effect is more inconspicuous when having foundry loam interlayer in foundation ditch, and horizontal floral tube precipitation system is applicable to variously-shaped big light-gauge foundation ditch, horizontal floral tube precipitation belongs to shallow-layer precipitation, the simple small investment of operation, instant effect；Precipitation system of the present utility model can carry out precipitation to big cross section foundation ditch with local and foundation ditch lateral seepage position according to job site situation, more inconspicuous than more serious position such as dewatering effect to infiltration, with increasing and adjust horizontal precipitation pipeline, applied widely；It is vertical pumping that well-points dewatering carries out precipitation to big cross section foundation ditch, it is typically all and uses both sides precipitation simultaneously to can be only achieved dewatering effect, if with side precipitation, opposite side dewatering effect is likely to inconspicuous, and horizontal precipitation pipeline can be horizontal-extending to opposite side from side, foundation ditch both sides dewatering effect can be made equally to compare balance, use this utility model to save the material of more than 1/2nd than well-points dewatering；Precipitation system of the present utility model runs 1-2 hour, soil body surface in foundation ditch is it can be seen that there is dry and cracked contraction gap, and after running 24 hours, water content fully achieves test water content and execution conditions, solve top layer infiltration and lateral seepage, save 7-15 days than conventional well point dewatering.
