Abstract
The utility model provides a pre-pressing pile sealing device for an anchor rod static pile. The pre-pressing pile sealing device comprise channel steel pipe frames (1), a hydraulic jack (2), steel pipe concretes (3), a counter-force beam (4) and limiting channel steel (5). A connection structure is that two groups of the channel steel pipe frames (1) are fixed through a fixing hole on a base by adopting a screw rod; the counter-force beam (4) is connected at the upper part between the two groups of the channel steel pipe frames (1); the limiting channel steel (5) is connected below the base of the channel steel pipe frames (1); the two steel pipe concretes (3) are mounted between the counter-force beam (4) and the limiting channel steel (5); and the hydraulic jack (2) is placed between the two steel pipe concretes (3). According to the utility model, a method for replacing the jack by utilizing the two steel pipe concretes is adopted, therefore, working faces of pile sealing, welding and the like are increased by continuously pressurizing a prefabricated static pile by adopting the steel pipe concretes, and the pile sealing efficiency is improved.
Description
Technical field
The utility model is a kind of anchor jacked pile precompressed envelope stake device, is mainly used in the precompressed envelope stake of anchor jacked pile.
Background technology
Anchor jacked pile is a new underpinning technique of strengthening soft foundation; With the innovation of other underpinning techniques many advantages are arranged relatively: friction during construction, noiselessness, equipment be simple, easy to operate, move flexibly; Can under place and space-constrained condition, construct; Both can be used for old premises base and reinforced and underpin, also can be used for the design of newly constructed house on soft foundation, and when old housing reform is made, can under the situation that does not stop production and do not move, carry out engineering and handle.The range of application anchor jacked pile of anchor jacked pile is applicable to the newly-built of foundation soils such as silt, clay, artificial earth fill, mucky soil or has built the ground processing or the foundation underpinning engineering of tier building, middle-size and small-size structure and factory building.Anchor jacked pile is particularly useful for following several kinds of needs and carries out that ground is handled or the situation of foundation underpinning: what be used for 1) that the uneven settlement of foundation reason causes heavyly splits the reinforcing of building and the correction of inclined building; 2) floor addition of building or factory building enlarge.On reinforced concrete foundation, reserve piling hole, embedded anchor bar, waiting to have constructed 2～3 layers begins piling later on; 3) in intensive building or near the precision instrument workshop, build tier building; 4) newly-built or enlarging multilayer building need adopt pile foundation, but do not have the independent piling duration; 5) pile foundation engineering accident treatment.
For guaranteeing the bearing capacity of anchor jacked pile, need carry out the stake of precompressed envelope to stake.Existing precompressed envelope stake device is continued to use the pile frame of piling.The high pile frame of 3m is adopted in piling, and equipment is comparatively heavy, installs, transportation, the dismounting pile frame is all inconvenient and have certain danger.In the piling process in addition, the top persistent pressure that jack need be fixed on static pressed pile prevents the stake bounce-back, operation operations such as the stake of influence envelope, welding, and operation is inconvenience very.
Summary of the invention
The utility model patent overcomes the heavy shortcoming of pile frame, and the pile frame improvement that original 3m is high is the high pile frame of 1m, reduces the pile frame height, and weight alleviates greatly, has reduced costs such as installation, transportation, dismounting, has improved the efficient of envelope stake.
The following technical scheme of passing through of the utility model realizes.
A kind of anchor jacked pile precompressed envelope stake device that is used for; The utility model is characterised in that: comprise channel-section steel pile frame, hydraulic jack, concrete filled steel tube, reaction beam, spacing channel-section steel, its syndeton is: two groups of channel-section steel pile frames adopt screw rod to fix through the fixing hole on its base; Between two groups of channel-section steel pile frames, be positioned at upper position and be connected with reaction beam, below channel-section steel pile frame base, be connected with spacing channel-section steel; Be provided with two concrete filled steel tubes and be installed between reaction beam and the spacing channel-section steel, hydraulic jack is placed between two concrete filled steel tubes.
The beneficial effect of the utility model is, adopted the method for two concrete filled steel tube displacement jack, increased work planes such as envelope stake, welding when utilizing concrete filled steel tube to continue pressurize to the precast static pressure stake, can improve and seal an efficient.
Description of drawings

B-B sectional view when Fig. 2 does not have jack for Fig. 1;
Fig. 3 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme of the utility model is further specified.
See Fig. 1, Fig. 2, shown in Figure 3; A kind of anchor jacked pile precompressed envelope stake device that is used for; The utility model is characterised in that: comprise channel-section steel pile frame 1, hydraulic jack 2, concrete filled steel tube 3, reaction beam 4, spacing channel-section steel 5, its syndeton is: two groups of channel-section steel pile frames 1 adopt screw rod to fix through the fixing hole on its base; Between two groups of channel-section steel pile frames 1, be positioned at upper position and be connected with reaction beam 4, below channel-section steel pile frame 1 base, be connected with spacing channel-section steel 5; Be provided with two concrete filled steel tubes 3 and be installed between reaction beam 4 and the spacing channel-section steel 5, hydraulic jack 2 is placed between two concrete filled steel tubes 3.
During construction of Static Pressure Pile; Hydraulic jack 2 is pressurizeed; After recording force value and reaching design load, two concrete filled steel tubes 3 are placed between reaction beam and the spacing channel-section steel 5, can hydraulic jack 2 displacements be deviate from; To preformed pile lasting pressure is provided by reaction beam 4 and concrete filled steel tube 3, stops the stake resilience.
After hydraulic jack 2 dismountings, reaction beam 4, concrete filled steel tube 3 and spacing channel-section steel 5 common formation later stage water booster systems.
Adopt this to test novel envelope stake device; Be before starting hydraulic jack with the existing envelope stake main distinction,, settle two diameter 110mm concrete steel pipes between reaction beam and the channel-section steel in the hydraulic jack both sides; Drive jack and carry out prepressing procedures; After reaching design load jack is withdrawn from,, promptly reached the purpose of displacement jack by two concrete steel pipes and the reaction beam value of keep-uping pressure.
