The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, easy construction, used construction machinery is few, the soil excavation engineering quantity is few, the amount of labour used is few, speed of application is fast, save material, reduced construction cost, good economical benefit is specially adapted to that groundwater table is higher, the building of pillar is arranged on building, the especially pile foundation of pile foundation that basement is arranged.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Mark among the figure: 1-structure base slab; The 2-seal ring; The 3-reinforcing bar; The 4-sealing rod; The 5-concrete cushion; The 6-stake; The 7-waterproof coating layer; 8-waterproofing mortar layer; 9-waterproof roll layer; The 10-topping.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
By as can be known shown in Figure 1; pile foundation base plate pile crown waterproof construction; comprise structure base slab 1; concrete cushion 5; the reinforcing bar 3 that arranges on stake 6 and edge stake 6 bearing of trends; the top of described stake 6; be provided with waterproof coating layer 7 above the exposed parts of stake 6 and the peripheral concrete cushion 5 thereof; waterproofing mortar layer 8 is laid on described waterproof coating layer 7 surfaces; the surperficial paving waterproof roll layer 9 of the waterproofing mortar layer 8 of described stake 6 peripheries; topping 10 is laid on described waterproof roll layer 9 surface; described structure base slab 1 is layed in the top of topping 10; the junction of described reinforcing bar 3 and stake 6 arranges seal ring 2; sealing rod 4 is set around the top of described stake 6; pick the cutter groove around the top of described stake 6; described sealing rod 4 is arranged in the groove, wide 10 ㎜ of described groove; dark 10 ㎜.Described reinforcing bar 3 is more than 4; used seal ring 2 is the reinforcing bar rubber O-ring seal; used sealing rod 4 is water-swelling rubber water bar, and used water-repellent paint is cement based penetration crystallization type water proofing paint, and described topping 10 is pea gravel concreten topping or cement mortar protective course.
Technological process of the present utility model is: cleaning basic unit → reinforcing bar 3 arranges the top of sealing rod 4 → stake 6, exposed parts and the peripheral brushing waterproof coating layer 7 → waterproofing mortar layer 8 → paving waterproof roll layer 9 → laying topping 10 thereof of stake 6 all around with the top of the junction cover seal ring 2 → stake 6 of stake 6.
It is as follows to build concrete operation step of the present utility model:
2, seal ring 2 and sealing rod 4 are set: reinforcing bar 3 puts the reinforcing bar rubber O-ring seal with stake 6 junctions, pick the groove of cutter wide 10 ㎜, dark 10 ㎜ in stake 6 top perimeter, in groove, arrange water-swelling rubber water bar, make it end to end, and be centered around in the top groove along the radian of water-swelling rubber water bar itself, water-swelling rubber water bar is forbidden to have the defective such as breach that ruptures.
3, the brushing waterproof coating layer 7: form waterproof coating layer 7 at the top of stake 6, exposed parts and the concrete cushion 5 external coating cement based penetration crystallization type water proofing paints in the peripheral 250 ㎜ scopes thereof of stake 6.Cement based penetration crystallization type water proofing paint divides two-layer brushing, and first floor thickness is not more than 1.2 ㎜, and the second layer is concentrating agents.Because the precondition of cement based penetration crystallization type water proofing paint crystallization forming process in concrete is to need moisteningly, get final product so only need the open fire on concrete cushion 5 surfaces cleaned out.
4, waterproofing mortar layer 8 is smeared in the shop: waterproof coating layer 7 maintenances were smeared the polymer cement waterproof mortar as waterproofing mortar layer 8 in the top of stake 6, exposed parts and the periphery shop thereof of stake 6 after 2 days.The polymer cement waterproof mortar adopts finished product siccative and emulsion mix to form, during construction the polymer cement waterproof mortar is placed the top of stake 6, with trowel to around spread out and put on, after stake 6 top completely spreads the thick polymer cement waterproof mortar of 20 ㎜, in the exposed parts of stake 6 and peripheral 500 ㎜ scopes thereof, spread out and put on the thick polymer cement waterproof mortar of 20 ㎜.Note in the work progress stake 6 is smeared into the circular arc that radius is not more than 20 ㎜ with the inner corner trim of concrete cushion 5 intersections, after the exposed parts periphery 500 ㎜ scope interpolymer cement waterproofing mortars shop of stake 6 is smeared and is finished, in 500 ㎜-700 ㎜ scope around the exposed parts of stake 6, look for the gentle slope with the polymer cement waterproof mortar to concrete cushion 5.
5, paving waterproof roll layer 9: at the surperficial paving waterproof roll layer 9 of the waterproofing mortar layer 8 of stake 6 peripheries, reserve the overlapping the slot size according to the width of selected coiled material, at the reference line position of paving waterproof roll layer 9 snap the line, in order to carry out the laying of waterproof roll layer 9 by this reference line.Laying method is undertaken by the coiled material construction technology, and job practices meets standard and pertinent regulations.The basic unit of coil waterproof layer 9 should be firm, and basal plane should clean, smooth, and hollowing, loosening phenomenon must not be arranged, and basic unit negative and positive angle is processed and met code requirement.The waterproof roll cementing agent for preparing must be finished in 4 hours, forbade out-of-date use.
6, lay topping 10: the construction of waterproof roll layer is complete, after the acceptance(check), lays cement mortar or pea gravel concreten on waterproof roll layer 9 surface as topping 10.
The laying of pile foundation base plate pile crown waterproof construction can be finished according to above-mentioned steps.Brushing waterproof coating layer 7, waterproofing mortar layer 8, waterproof roll layer 9 and topping 10 material therefors are selected voluntarily according to actual conditions in the process of deployment, and required size also will be selected to set according to the practice of construction needs.
