Abstract
The invention provides an anti-crack and anti-leak construction method of arranging a tower crane foundation below a waterproof baseplate, which is characterized in that the anti-crack and anti-leak construction method adopts the following steps: 1) constructing the tower crane foundation; 2) mounting a tower crane, and then constructing a flexible mat layer, a concrete mat layer, a waterproof layer, a waterproof protective layer and the waterproof baseplate from top to bottom around the tower crane foundation, wherein the bottom surface of the flexible mat layer is leveled with the top surface of the tower crane foundation; 3) adopting pure soil for tamping and filling in the range of the tower crane foundation, then using C20 anti-leak concrete for sealing from the center of the tower crane to the periphery, carrying out calendering and anti-leak treatment, and making a 1-5% drainage slope; 4) arranging stress inducing joints of extruded polystyrene boards on the edge outside the drainage slope and the periphery of the tower crane, and further using a weather-proofing silicone sealant for tight caulking; and 5) dismantling the tower crane after completing the construction of a building, and using two layers of coiled materials for making an reinforcing waterproof layer in the range of the tower crane foundation. The anti-crack and anti-leak construction method can effectively solve the different settlement problem between the tower crane foundation and the waterproof baseplate, the problem of producing negative bending moment above the tower crane foundation, the waterproofing failure problem and the water accumulation settlement problem of the tower crane foundation.
Description
Technical field
The invention provides a kind of arranging tower crane foundation below waterproof baseplate anti-crack and anti-leak construction method, belong to technical field of building construction.
Technical background
It is that tower crane directly is located in the waterproof base plate that tower crane is set in traditional waterproof base plate, can produce tower crane and waterproof base plate settlement difference, tower crane in the tower crane running to problems such as antiseepage base plate generation hogging moments, the waterproof coiled material of tower crane and the fracture of waterproof back plate connections and tower crane and waterproof base plate is broken, cause the waterproof base plate leakage, directly influence the waterproof effect of waterproof base plate.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome above-mentioned defective, prevent that tower crane is placed on the arranging tower crane foundation below waterproof baseplate anti-crack and anti-leak construction method of the leakage problems in the sole plate.Its technical scheme is for adopting following steps:
1) tower crane construction;
2) tower crane is installed, carry out the construction of flexible cushion, concrete cushion, waterproofing course, fish tail and waterproof layer, waterproof base plate then from bottom to top around tower crane, wherein probe into tower crane 200～300mm around flexible cushion, concrete cushion, the waterproofing course, and the bottom surface of flexible cushion is concordant with the end face of tower crane;
3) adopt plain earth rammer to fill out in the tower crane scope, plain earth rammer is filled to the following 80～120mm of waterproof plate top surface, in tower crane, seal and the press polish antiseepage with the C20 impervious concrete around the mind-set then, do 1～5% weathering, wherein the water reducing agent of admixture cement consumption 1～3% in the C20 impervious concrete;
4) weathering outward flange and tower crane outer periphery 20～30mm is thick, 80～100mm the is high stress induced seam of extruded polystyrene board, and iron into 20～30mm deeply with electric iron, it is tight to fill out embedding with weather-proof silicone adhesive again;
5) after architecture construction finishes, remove tower crane, cut off foundation bolt, do the reinforcement waterproofing course with two layers of coiled materials in the tower crane scope, all the other each regional structure layer ways are identical with the waterproof base plate.
The present invention compared with prior art, its advantage is:
1, the designing technique measure that breaks away from by tower crane and underground garage base plate has solved tower crane and waterproof base plate settlement difference problem;
2, the tower crane end face is concordant with the flexible cushion bottom surface, absorbs negative flexure stress with flexible cushion, solves tower crane produces hogging moment to the waterproof base plate after sealing problem;
3, stress induced seam can be in case the tower crane vibration causes the infiltration of temporary joint cracking.
Description of drawings
Fig. 1 is the structural representation that tower crane is set under the waterproof base plate of the present invention;
Fig. 2 is the basic schematic behind the dismounting tower crane.
Among the figure: 1, tower crane 2, flexible cushion 3, concrete cushion 4, waterproofing course 5, waterproof base plate 6, stress induced seam 7, weathering 8, plain soil 9, tower crane 10, reinforcement waterproofing course 11, steel plate for sealing water 12, fish tail and waterproof layer
The specific embodiment
As the described embodiment of Fig. 1-2, adopt following steps:
1) tower crane 1 construction;
2) tower crane 9 is installed, carry out the construction of flexible cushion 2, concrete cushion 3, waterproofing course 4, fish tail and waterproof layer 12, waterproof base plate 5 then from bottom to top around tower crane 1, wherein probe into tower crane 1 apart from 200mm around flexible cushion 2, concrete cushion 3, the waterproofing course 4, and the bottom surface of flexible cushion 2 is concordant with the end face of tower crane 1;
3) adopting plain soil 8 to ram in tower crane 1 scope fills out, plain soil 8 rams and is filled to the following 100mm of waterproof base plate 5 end faces, in tower crane 9, seal and the press polish antiseepage with the C20 impervious concrete around the mind-set then, do 2% weathering 7, wherein the water reducing agent of admixture cement consumption 2% in the C20 impervious concrete;
4) the stress induced seam 6 of weathering 7 outward flanges and tower crane 9 outer periphery 30mm extruded polystyrene board thick, that 100mm is high, and iron into 30mm deeply with electric iron, it is tight to fill out embedding with weather-proof silicone adhesive again;
5) after architecture construction finishes, remove tower crane 9, cut off foundation bolt, do reinforcement waterproofing course 10 with two layers of coiled materials in tower crane 1 scope, all the other each regional structure layer ways are identical with waterproof base plate 5.
