Description
Technical field
The invention belongs to technical field of building construction, and in particular, to a kind of rapid construction of pit earthwork at raining season method.
Background technology
Pit earthwork construction in, weather conditions be always one influence the duration an important factor for, in case of project site is located at
Business district, most of units in charge of construction will face the situation that the duration is tight, dregs haul distance is remote, transit route vehicle flowrate is big, and be permitted
More business district projects only allow the hour that carries on construction work at night, many units in charge of construction whether between rainy day venture construction and schedule delays it is difficult
It chooses, and often therefore even there is construction accident in influence construction quality in order to compress the mistake resolution that the duration is made, even
Bring huge economic losses and construction personnel's security risk.
Therefore, the above problem is urgently to be resolved hurrily.
Invention content
Goal of the invention：For overcome the deficiencies in the prior art, the object of the present invention is to provide one kind can be in rainy season situation
Lower pit earthwork construction method that is conscientiously effective, reducing Pluvial construction safety hidden danger.
Technical solution：The present invention provides a kind of rapid construction of pit earthwork at raining season methods, which is characterized in that including following
Construction procedure：
1）Before pit earthwork excavation construction, after completing positioning, unwrapping wire, the work of datum mark pilot measurement, fills and leads up foundation pit surrounding ground and stay
Outer slope carries out place mat, in the foundation pit structure top ground with brick or sandstone to the outer slope and detail design traffic route
Place builds the brick wall that intercepts water by laying bricks or stones, and the brick wall bilateral that intercepts water smears cement mortar, and the slope surface that intercepts water is made on ground on the outside of water stop, described
The slope surface that intercepts water smears cement mortar surface, and the slope surface top of the slope periphery of intercepting water is arranged brick drainage groove, is set in four corners of foundation pit
Catch pit is set, immersible pump is set in catch pit；
2）Pit earthwork excavation construction, stage excavation, excavation face should make stable side slope from top to bottom for the earthwork, to the foundation pit and
Side slope, which synchronizes, carries out supporting；When earth excavation to foundation pit bottom, covered in time, and build the gutter interconnected in time
And sump, sump is interior to be arranged immersible pump.
The rainy season earthwork construction scheme of the present invention, mainly by slope outside simple Job readiness early period such as foundation pit, intercept water it is outer
The pumping equipments such as wall, drainage groove, gutter and sump, progress Pluvial protect in advance, have prevented the outer rainwater of foundation pit and have flowed into foundation pit
Possibility, reduce drainage of foundation pit pressure, shorten the base pit dewatering period, and then realize pit earthwork at raining season rapid construction.
Further, a kind of above-mentioned rapid construction of pit earthwork at raining season method, which is characterized in that when rainfall, the side
Slope plastic covering film.
Side slope plastic covering film prevents the rain wet slump of side slope.
Further, a kind of above-mentioned rapid construction of pit earthwork at raining season method, which is characterized in that foundation pit lower part soil body soil
When the Pluvial is excavated by side, example adds 5~10% concrete accelerators and carries out whitewashing solidification in mass ratio in concrete grout, has whitewashed
Whitewashing position is covered using plastic film at rear.
Whitewashing solidification can be carried out in Pluvial and non-Pluvial, mitigate the influence then stablized to foundation pit.
Further, a kind of above-mentioned rapid construction of pit earthwork at raining season method, which is characterized in that in the excavation slope
Backwater drainpipe is set at a certain distance in soil.
Be arranged the backwater drainpipe make in order to prevent earth's surface water penetration to gunite concrete face layer generate pressure, simultaneously prevent
Only rain penetration reduces the interfacial adhesion between soil strength and the soil body and soil nailing, causes foundation pit collapse, landslide, is realizing ground
While face drains, the rainwater for penetrating into side slope is excluded using backwater drainpipe, ensures deep pit monitor
Further, a kind of above-mentioned rapid construction of pit earthwork at raining season method, which is characterized in that the collecting gutter is by width
600mm, deep 500~600mm settings, the gutter gradient 1%, apart from 0.2~0.3m of foundation pit leftover bits and pieces；The sump is along the base
Cheat the setting of bottom edge angle, diameter 1.5m.
Above-mentioned is specific collecting gutter structure, and multiple construction experience proves that this structure collecting gutter has structural stability, no
Easy turned-down edge.
Further, a kind of above-mentioned rapid construction of pit earthwork at raining season method, which is characterized in that the sump bottom is low
In Foundation Pit bottom surface 1.5m, setting presses bottom, the ponding in sump to be arranged at any time by immersible pump without sand drain pipe, filtrate and rubble
Go out.
Above-mentioned is specific catch pit structure, and above structure makes catch pit be not easy to form mud mortar, keeps draining smooth, is protected
The bottom drying of card hole.
Further, a kind of above-mentioned rapid construction of pit earthwork at raining season method, which is characterized in that if foundation pit not on earth or
When the collecting gutter and sump of substrate are not fixed, such as heavy showers, foundation pit is interior to be drained in the rain using slush pump.
Slush pump cooperation draining, prevents mud from destroying hole bottom and pumping equipment.
Above-mentioned technical proposal can be seen that the present invention and have the advantages that：
1）Rainy season earthwork construction scheme provided by the present invention, it is pre- by excavating early period in the simple Job readiness progress foundation pit Pluvial
Protection has prevented the possibility that the outer rainwater of foundation pit flows into foundation pit, has reduced drainage of foundation pit pressure, shorten the base pit dewatering period, realize rain
Season pit earthwork rapid construction；
2）This construction method provides the drainage construction scheme that do not stop work in the Pluvial, reduces because of the improper construction brought of Pluvial construction drainage
Security risk.
Specific implementation mode
Embodiment
A kind of rapid construction of pit earthwork at raining season method, which is characterized in that including following construction procedure：
1）Before pit earthwork excavation construction, the drainage system of construction site should be improved as possible, ensure that construction site is drained with extraneous
It is unobstructed, and the foundation pit water blocking measure of effect certainly is taken, to prevent the surface water from flowing into foundation pit, for this purpose, completing positioning, putting
After line, the work of datum mark pilot measurement, fills and leads up foundation pit surrounding ground and stay outer slope, build by laying bricks or stones and intercept water at the foundation pit structure top ground
Brick wall, the brick wall bilateral that intercepts water smears cement mortar, and the slope surface that intercepts water is made on ground on the outside of water stop, and the slope surface that intercepts water is smeared
