Problems solved by technology

In order to solve this problem, it is considered to set the foundation of the tower crane in the podium. The usual method is to first drill four cast-in-place piles in the soil pit in the podium, then dewater, excavate the earth, and pour on the four cast-in-place piles. Tower crane foundation, but adopting the tower crane foundation structure in the above-mentioned prior art requires excavation, precipitation, backfilling and other operations, and the earthwork construction volume is large. After the demolition is completed, the floor is rebuilt. During this process, the site needs to be continuously dewatered, which may even cause a decrease in the waterproof performance of the building.
[0004] Therefore, using the existing technology to make the tower crane foundation, the precipitation cycle is long, the installation of the tower crane is difficult, and the use of the tower crane lags behind

Embodiment 1

[0033] Embodiment 1: Referring to accompanying drawings 1 to 9, a tower crane foundation for construction includes a tower crane foundation cap 2 and four cast-in-situ piles 1 fixedly connected to the bottom of the tower crane foundation cap. The height of the exposed base under the position is 5-7 meters, and a water-stop structure is arranged between the cast-in-place pile and the building floor.

[0034] The water-stop structure of this embodiment is that an advanced water-stop plate 3 is fixedly connected with the four cast-in-place piles, and a water-swelling water-stop strip 4 is arranged between the cast-in-place piles and the advanced water-stop plate. The building bottom plates are connected by elastic material components, and the settlement space is reserved between the advanced water stop plate and the building bottom plate poured after the upper part; Rubber waterstop 5, polyvinyl chloride mastic 6 on the foamed plastic board 7 and the outside of the rubber waterst...

Embodiment 2

[0132] Embodiment 2: Referring to accompanying drawings 10 and 11, a tower crane foundation for construction includes a tower crane foundation cap 2 and four cast-in-situ piles 1 fixedly connected to the bottom of the tower crane foundation cap. The height of the exposed base under the position is not less than 3 meters, and a water-stop structure is arranged between the cast-in-place pile and the building floor.

[0133] The water-stop structure of this embodiment is an additional cap 8 connected to the lower part of the building floor, and a water-expandable water-stop strip 4 is arranged between the additional cap and the cast-in-place pile, and the additional cap is poured together with the building floor.

[0134] This embodiment is applicable to the occasion where the building adopts the engineering pile foundation, and its manufacturing method is similar to Embodiment 1, wherein, the difference is the treatment of the bottom plate, and the technological process of the bo...

Abstract

The invention discloses a tower crane foundation for building, comprising foundation platform of tower crane, at least four grouting piles under the foundation platform of tower crane. It is characterized in that foundation bottom can be revealed from the top of said grouting pile and water stopping structure is set between grouting piles and building bottom plate. The invention discloses the manufacturing method for said tower crane at the same time. Aiming at high-rise building with ultra-large area and multi-floor basement, the invention adopts tower crane foundation of high-pile platform. Not only the problem that because high-rise floor retracts in podium tower crane can not be attached with it is solved but also the assignment of tower crane becomes flexible, covering area is bigger and it can be used in advance. Mechanical utilization achieves to the maximum and it has a very good effect for decreasing manual consumption and construction period.

Description

technical field [0001] The invention relates to a tower crane used for hoisting operations in the construction industry, in particular to a tower crane foundation and a manufacturing method thereof. Background technique [0002] Tower cranes are important equipment for hoisting and transportation operations in the construction industry. Most of the vertical transportation of building materials is completed by tower cranes. In order to ensure the smooth operation of the tower crane, the tower crane is installed on the foundation of the tower crane. The foundation of the tower crane must meet two requirements: one is to transmit the load on the upper part of the tower crane to the foundation evenly and not exceed the ground endurance; Under all circumstances, the overall stability can be maintained without tipping over. Therefore, the tower crane foundation is usually composed of a larger size concrete cap. In order not to affect the construction of...
