Abstract
The invention discloses a waterproof construction of a basement soleplate and a construction method thereof. The waterproof construction of the basement soleplate is characterized in that a layer of plastic film is arranged on a plain concrete cushion layer by a border adhibiting method, and a cold binder is point-bonded between the plastic film and a waterproof rolling material. A seal ring is welded on a pile reinforcing bar, a sleeve pipe is made outside the pile reinforcing bar, hemp threads are stuffed in a gap of the sleeve pipe below the seal ring, and a waterproof sealant is stuffed in the gap above the seal ring, and the gap is sealed. A two-time casting and compacting mode of soleplate concrete is adopted, the pile top extends into the position of the soleplate concrete to cast and compact for the first time, casting and compacting are carried out by adopting UEA concrete, an expansion agent is mixed when the concrete at the position is cast and compacted, and the gradient of a construction joint casted and compacted for the first time is 30-45 degrees. The overlapping position of the sloping segment and the horizontal segment at the construction joint is made into a circular arc angle by plastering chloroprene rubber latex cement mortar. A fine gravel concrete cushion block is bonded and precast on the obliquely laid waterproof rolling material. The waterproof construction of the basement soleplate has good waterproof effect and strong practicability.
Description
Technical field
The present invention relates to building field, particularly a kind of basement bottom board water proof structure and job practices.
Background technology
Underground water generally has certain hydraulic pressure, and flexible waterproof layer has a point failure then to cause the inefficacy of whole waterproof system.The high-rise building basement is provided with stake usually, because structure and antidetonation need stake top reinforcing bar can stretch into basement, makes basement and pile foundation be linked to be integral body, so that the horizontal force that horizontal force that pile is passed by upper building comes or earthquake produce.Tradition basement water proof structure is as follows: do concrete cushion with the foundation soil contact position, do waterproofing course then on concrete cushion, do concrete then on waterproofing course.Because the stake reinforcing bar stretches into underplate concrete, waterproofing course if there is not rational water proof structure, will certainly cause basement leakage disconnecting through occurring in the process of pile body.
Summary of the invention
At the deficiencies in the prior art, purpose of the present invention provides a kind of basement bottom board water proof structure and job practices, solves the problem of basement bottom board king-pile reinforcing bar position percolating water.
The object of the present invention is achieved like this:
The present invention is empty shop layer of plastic film on plain concrete cushion layer, the sticking cold cementing agent of point between plastic sheeting and waterproof roll.This structure both can make waterproof roll and plain concrete cushion layer throw off, and can protect waterproof roll again.Make the waterproof roll secure bond on the underplate concrete of top, waterproofing course and bottom plain concrete cushion layer break away from, so waterproof roll is subjected to pulling force and little during structural change, avoids waterproof roll to destroy the basement waterproofing structure was lost efficacy.
The present invention does the welding seal ring on the stake reinforcing bar, the stake reinforcing bar is made sleeve pipe outward, and with the flax silk filling, seal ring is above to be filled in and seal with waterproof sealing cream below seal ring in the gap of sleeve pipe.Because the water capacity easily enters basement along exposed reinforcing bar, can prevent effectively that by above-mentioned measure this phenomenon from taking place.
Underplate concrete adopts and waters the mode of smashing twice among the present invention, stake top is stretched into the underplate concrete position and is carried out watering first time and smash, and disturbing concrete is made trapezoidal shape above stake for the first time, employing UEA casting and compacting of concrete, the admixture expansion agent helped guaranteeing concrete compaction when this located casting and compacting of concrete.Water for the first time and smash the constuction joint gradient and adopt 30~45 degree, do not adopt the right angle, purpose is to make for the first time that disturbing concrete and second time disturbing concrete effectively is connected, and is unlikely the weak part that becomes percolating water.
Oblique section at the constuction joint place of the present invention and horizontal segment lap-joint plaster with the polychloroprene latex cement mortar and make arc chord angle, if oblique section and horizontal segment lap-joint are wedge angles, in the structure sediment process, waterproof roll is cut easily to be split.
The present invention does the waterproof reinforced layer in constuction joint upper horizontal section, and waterproof reinforced layer length is not less than 250mm, loses efficacy even do the measure of welding seal ring on the stake reinforcing bar, can also prevent that by this construction measure basement water from pushing up the chamber base plate that permeates the ground from stake.
The present invention is bonded and precast pea gravel concreten cushion block on the waterproof roll of tiltedly spreading.8mm~12mm small crushed stone of evenly beating in before the underplate concrete initial set, it is dark to make stone imbed concrete 1/3, and this measure purpose is to make the waterproof roll of oblique shop and underplate concrete become integral body, thus waterproof effectively.
Good water-proof effect of the present invention, practical.

The specific embodiment
Be described in detail below in conjunction with Fig. 1, the present invention's structure comprises plain concrete cushion layer 5, flax silk 6, seal ring 7, waterproof sealing cream 8, sleeve pipe 9, plastic sheeting 10, waterproof roll 11, waters for the first time and water concrete 1, the second time of smashing concrete 2, the polychloroprene latex cement mortar 12 of smashing.
The thick plastic sheeting 10 of empty shop one deck 0.3mm on plain concrete cushion layer, the sticking cold cementing agent of point between plastic sheeting 10 and waterproof roll 11.
Do welding seal ring 7 on the stake reinforcing bar, seal ring 7 diameters are the 3mm stalloy than the big 2~3cm of bar diameter.The stake reinforcing bar is made sleeve pipe 9 outward, and with flax silk 6 fillings, seal ring is filled in and sealed with waterproof sealing cream 8 more than 7 below seal ring in the gap of sleeve pipe 9.Underplate concrete adopts and waters the mode of smashing twice, stake top is stretched into underplate concrete 9 positions and is carried out watering the first time and smash, disturbing concrete is made trapezoidal shape above stake for the first time, adopt the UEA casting and compacting of concrete, admixture expansion agent when this locates casting and compacting of concrete, water for the first time and smash constuction joint gradient employing 30~45 degree, avoid vertical construction joints to cause structure tension performance not good.Water for the first time and smash laying water-proof coiled material 11 behind 8~12h, carry out watering the second time after waterproof roll 11 is laid and finished and smash.
The oblique section in constuction joint place is plastered with polychloroprene latex cement mortar 12 with horizontal segment lap-joint and is made arc chord angle.Constuction joint upper horizontal section is done the waterproof reinforced layer, and waterproof reinforced layer length is not less than 250mm.
Bonded and precast pea gravel concreten cushion block on the waterproof roll 11 of oblique shop, the pea gravel concreten pad thickness is 30mm, end opening is 80mm*80mm, suitable for reading is 70mm*70mm, the iron wire that band is connected with the structural concrete cast on the prefabricated pea gravel concreten cushion block, every square metre of volume pea gravel concreten cushion block piece number is no less than four, is convenient to structural concrete and waterproof roll 11 formation integral body.
8mm~12mm small crushed stone of evenly beating in before the underplate concrete initial set, it is dark to make stone imbed concrete 1/3, in order to avoid the polychloroprene latex cement mortar 12 and underplate concrete delamination on underplate concrete upper strata.Underplate concrete top polychloroprene latex cement mortar 12 thickness are 20cm.
