On the ground of the both sides of this longitudinal type girder steel and lateral type girder steel, plant and be implanted with several expansion bolts, injecting glue is strengthened fixing between expansion bolt and the ground;
Head at this expansion bolt is fixed with attachment lug with nut, and this attachment lug with this longitudinal type girder steel and the pressing of lateral type girder steel on the ground;
Putting on the shelf at this lateral type girder steel is provided with the piling frame, and the stake in the jack on the piling frame and this piling hole connects.
In preferable technical scheme: described piling hole is in length and breadth arranges.
In preferable technical scheme: described expansion bolt is of a size of φ 12～φ 16mm, and the degree of depth that described expansion bolt gets into ground is not less than 100mm.
In preferable technical scheme: described attachment lug is also fixing with described longitudinal type girder steel and the welding of lateral type girder steel respectively.
Compared with prior art, the beneficial effect that the utlity model has is:
1) the counter-force load that provides of flooring is capable of using whenever and wherever possible;
2) do not receive the restriction of chamber height, can be in height 2m following space construction;
3) the detachable pan position of easy construction is safe and reliable, simple.
Description of drawings
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 are respectively the sketch mapes step by step of the utility model;
Fig. 7 A, Fig. 7 B are the step sketch mapes of dismounting section steel beam.
The specific embodiment
For the problem of the flooring depression that solves building, the method that the utility model adopts is a kind of method of using group anchor static pressed pile to prevent land subsidence, and it comprises:
1) on ground 10, measures the piling hole site, beat at each place, piling hole site then and dig out piling hole 11 (as shown in Figure 1);
Wherein: described ground 10 can be the flooring of existing building, also can be structure floor newly-built on the flooring of existing building.If newly-built structure floor, the piling hole 11 on this newly-built structure floor should penetrate original flooring so, passes through for stake.
And described piling hole 11 generally is in length and breadth arranges.
2) set up longitudinal type girder steel 12 in the piling hole around 11, and on longitudinal type girder steel 12, set up lateral type girder steel 13 (as shown in Figure 2), the dismountable bolt of employing (not giving diagram) is connected between this longitudinal type girder steel 12 and the lateral type girder steel 13;
3) several expansion bolts 20 of plantation on the ground 10 of the both sides of this longitudinal type girder steel 12 and lateral type girder steel 13, and injecting glue 21 is strengthened and is fixed (as shown in Figure 3) between expansion bolt 20 and ground 10;
In general, use the expansion bolt 20 of φ 12～φ 16mm, the degree of depth that bolt gets into ground 10 should be not less than 100mm.
4) with nut 23 attachment lug 24 is fixed on the head of this expansion bolt 20, and utilizes this attachment lug 24 that this longitudinal type girder steel 12 and lateral type girder steel 13 are pressed together on (like Fig. 3, Fig. 4, shown in Figure 5) on the ground 10;
Wherein: preferably that attachment lug 24 is fixing with section steel beam 12,13 welding;
5) on this lateral type girder steel 13, set up piling frame 30, carry out static pressed pile with the jack on the piling frame 30 then and handle, thereby stake 40 is pressed into 11 interior predetermined altitude and the envelope stakes (as shown in Figure 6) to this piling hole;
Wherein: longitudinal type girder steel 12 and the size dimension of lateral type girder steel 13 and the sizing grid of formation, and the specification of bolt, size etc., calculate decision by the counter-force of static pressed pile processings needs.
6) the piling work and envelope stake work in another piling hole 11 are carried out in the position of mobile this piling frame 30, all accomplish until the piling work and the envelope stake work in all piling holes 11;
Wherein: after the piling hole 11 of a certain horizontally-arranged pressed; Can described longitudinal type girder steel 12 (be combined shown in Fig. 5, Fig. 7 A with lateral type girder steel 13 partial disassemblies; Dismantle No. 2 lateral type girder steels 13 and 4,5,6, No. 7 longitudinal type girder steels 12); Then reinstalling this longitudinal type girder steel 12 that disassembles in other positions (combines shown in Fig. 7 A, Fig. 7 B with lateral type girder steel 13; Increased No. 3 lateral type girder steels 13 and 16,17,18, No. 19 longitudinal type girder steels 12), and begin to press the piling hole 11 of another horizontally-arranged.
7) remove this longitudinal type girder steel 12 and lateral type girder steel 13.
The main feature of the utility model is: through swell fixture and attachment lug 24 longitudinal type girder steel 12 and lateral type girder steel 13 are anchored on the ground 10; Fixing with connecting between longitudinal type girder steel 12 and the lateral type girder steel 13 then; Just can provide enough counter-force to piling frame 30, carry out piling work smoothly.And the method for use the utility model, the place construction does not need mud emission, the construction plant civilization, and the static pressed pile strengthening construction of sinking for industrial premises ground 10 provides reliable feasible method.
Can know that from the said method content the utility model also provides a population anchor static pressed pile structure, be on ground 10, to beat to be carved with piling hole 11, and:
Set up longitudinal type girder steel 12 in the piling hole around 11, and put on the shelf at longitudinal type girder steel 12 and to be provided with lateral type girder steel 13, the dismountable bolt of employing is connected between this longitudinal type girder steel 12 and the lateral type girder steel 13;
On the ground of the both sides of this longitudinal type girder steel 12 and lateral type girder steel 13, plant and be implanted with several expansion bolts 20, injecting glue 21 is strengthened and is fixed between expansion bolt 20 and the ground 10;
Head at this expansion bolt 20 is fixed with attachment lug 24 with nut 23, and this attachment lug 24 is pressed together on this longitudinal type girder steel 12 and lateral type girder steel 13 on the ground 10;
Putting on the shelf at this lateral type girder steel 13 is provided with piling frame 30, and the stake 40 in the jack on the piling frame 30 and this piling hole 11 connects.
More than explanation is just illustrative as far as the utility model; And nonrestrictive, those of ordinary skills understand, under the situation of spirit that does not break away from claim and limited and scope; Can make many modifications, variation or equivalence, but all will fall within the protection domain of the utility model.
