Embodiment 1

[0061] Such as Figure 5-Figure 7 Shown:

[0062] An operating frame body for canceling the backfilling of the outer wall of a basement includes several support piles 1, and the support piles 1 are rotary drilling bored piles. The shape of several supporting piles 1 arrangement is adapted to the shape of the foundation pit, and the quantity of supporting piles 1 is determined according to the size of the basement construction. In this embodiment, take a rectangular basement as an example, such as Figure 5 As shown, there are 34 support piles 1, the distance between adjacent support piles is 2.3m, and the adjacent support piles are on the side of the empty surface of support piles 1 after foundation pit excavation ( Figure 7 The side B in is the free surface, Figure 7 A side in the middle is the soil surface) sprayed with a concrete base 2, and the thickness a of the concrete base 2 is 80mm; in the concrete base 2, a steel mesh sheet-3 is provided, and the outside of the...

Embodiment 2

[0066] Such as Figure 1-Figure 7 Shown:

[0067] The construction method for canceling the backfilling of the basement outer wall by adopting the operating frame body for canceling the backfilling of the basement outer wall in the above-mentioned embodiment 1 includes the following steps:

[0068] (1) construct the operating frame body that cancels the backfilling of the basement wall in Example 1:

[0069] a, construction foundation pit support pile 1, this support pile 1 adopts the rotary drilling bored pile;

[0070] b. Excavation of earth and stone, sprayed concrete base 2 between support piles 1 after excavation;

[0071] Before the sprayed concrete base 2, the reinforcement mesh 1 3 in the concrete base 2, the external pressure reinforcement reinforcement 4 and the reinforcement 6 are arranged according to the following design scheme:

[0072] ①Reinforcement mesh one 3: Φ8@200 double-layer two-way reinforcement mesh is arranged on the inner side of support pile 1;

Abstract

The invention relates to an operation frame body capable of cancelling backfilling of a basement outer wall and a construction method. The construction method includes the steps that the operation frame body capable of cancelling backfilling of the basement outer wall is constructed firstly, then a series of construction of a basement bottom plate are conducted, and finally a thermal insulation layer and a waterproofing layer on the outer facade of a basement wall body are constructed and concrete of the outer facade of a basement and a basement floor face are poured at the inner side of the operation frame body. By adoption of the operation frame boy capable of cancelling backfilling of the basement outer wall and the construction method, the procedure of concrete backfilling in a traditional basement construction method can be canceled, meanwhile, no influence on construction of waterproof of the outer facade of the basement and other engineering can be guaranteed. By adoption of the construction method, land utilization of at least 0.3-1.2m basement perimeter can be enlarged, or earth-rock of 0.3-1.2m basement perimeter can be less excavated, so that unnecessary costs on a leveling layer, a waterproof protection layer, a brick protection wall, an external formwork, an external frame pipe, backfilling earth and the like of outdoor facades can be saved.

Description

technical field [0001] The invention relates to a construction method of a basement, in particular to an operating frame and a construction method for canceling the backfilling of the basement exterior wall. Background technique [0002] With the continuous reduction of land resources and the continuous improvement of construction technology, the height and depth of housing construction are constantly developing into the air and underground. The height of buildings is getting higher and higher, and the depth of basements is also getting deeper and deeper. [0003] Traditional basement construction methods mainly include the following steps: [0004] (1) Construction foundation pit supporting piles; [0005] (2) Excavate earth and stone, and spray concrete base between the support piles after excavation (configure steel mesh and reinforcement according to design); [0006] (3) Construction basement floor C20 concrete cushion (surface polished); [0007] (4) Construct the w...
