Accompanying drawing explanation
Fig. 1 is first embodiment of the present invention and second embodiment sleeve method damaged stake process construction method used construction equipment structure organigram used.
Detailed description of the invention
As an embodiment as shown in Figure 1 of the present invention, main purpose is operating principle and the implementation method of introducing the first sleeve method damaged stake process construction method and construction equipment used thereof.First, composition graphs 1 introduces sleeve method of the present invention damaged stake process construction method construction equipment structure structure used and operating principle.This construction equipment comprises pitching pile machine (1), steel pipe sleeve (2) two parts, wherein pitching pile machine (1) comprises crane (3), vibrating device (4), sleeve fixture (5) three part, crane (3) is wherein connect vibrating device (4) with sleeve fixture (5) to have the facility of certain altitude, vibrating device (4) is for providing the equipment of pitching pile or pile pulling power, sleeve fixture (5) is for being connected to the utensil that steel pipe sleeve (2) can firmly clamp by crane (3), steel pipe sleeve (2) is the tubular device pending damaged stake can put in the inner.Vibrating device (4) in the present embodiment can be vibratory equipment as vibrating hammer, pneumatic vibrating equipment, hydraulic vibration equipment, the one or more combination in hammering equipment (as pile hammer), silent piling dynamicliquid pressure device also can be selected to substitute vibrating device (4).The facility that crane (3) can match with vibrating device (4), such as, when adopting vibrating hammer as vibrating device (4), crane (3) can be selected to carry out coordinative construction, also can vibrating device (4) be installed on digging machine, be made into manipulator.The present embodiment with lower part, introduce the first sleeve method damaged stake process construction method.The main purpose of this first the first sleeve method damaged stake process construction method is by stake (6) the correcting and then reinforcing process of tilting or rupture.This first sleeve method damaged stake process construction method comprises following five steps.First, location needs the stake (6) of the inclination of correction righting.Complete the first step, enter second step.In this step, utilize steel pipe sleeve (2) as shown in Figure 1, the pile crown of the stake (6) of tilting is placed in steel pipe sleeve (2).Complete second step, enter the 3rd step.In this step, steel pipe sleeve (2) is progressively inserted the soil body along stake (6) incline direction tilted.The method inserted can adopt pitching pile machine (1) as shown in Figure 1 to implement, when the angle of inclination of stake (6) is larger, by the direction of crane (3) adjustment steel pipe sleeve (2), make the direction of insertion of steel pipe sleeve (2) consistent with the direction of stake (6).The insertion depth of steel pipe sleeve (2) can be determined according to the tilting section length of stake (6), can be basically identical with the tilting section length of stake (6).Thus complete the 3rd step of the present embodiment, enter the 4th step.In this step, object is by the tilting section righting of steel pipe sleeve (2) together with the raked pile or stake that are positioned at steel pipe sleeve (2).The method of righting; can at the top time horizontal force of steel pipe sleeve (2) by steel pipe sleeve (2) together with stake (6) righting being positioned at steel pipe sleeve (2); under the protection of steel pipe sleeve (2), stake (6) can be avoided occurring the secondary damage such as bending in by the process of righting.Before stake (6) righting, in soil body squeeze side, Pile side soil body can also be removed, so that righting construction.Thus complete the 4th step of the present embodiment, enter the 5th step.In this step, back of the body soil side in stake (6) righting process can leave the space stayed after pile body moves, for the ease of the use of stake after righting (6), the hole that the fillers such as sand, cement, mortar can be adopted the 4th step to be constructed stay in the soil body thus complete the first sleeve method of the present invention damaged stake process construction method, completes the correcting and then reinforcing of stake (6).In the present embodiment, as the PHC pile tube that stake (6) is hollow, reinforcing can be filled at the hollow part steel concrete of stake (6).In the present embodiment, after by the righting of stake (6), sleeve can be extracted recycling.In the present embodiment, after by stake (6) righting, utilize vibration, static pressure or heavy tamping method by pile body from disconnected position compound.
As second embodiment as shown in Figure 1 of the present invention, main purpose is to introduce the second sleeve method damaged stake process construction method, and the main purpose of this processing method is extracted at the waste and old stake (6) residued in the soil body.Same first embodiment of construction equipment that the present embodiment is used.The second sleeve method damaged stake process construction method that the present embodiment is introduced comprises four steps, and first three step is wherein similar to first embodiment.In the 4th step of the present embodiment, be to utilize steel pipe sleeve (2) together to extract together with the stake (6) being positioned at steel pipe sleeve (2) with the difference of first embodiment.Because generally the stake (6) residued in soil mostly is reinforced concrete pile, because the anti-pulling capacity of reinforced concrete pile is low, in addition pile side resistance is large, stake (6) is directly extracted by general being difficult to from the soil body, after steel pipe sleeve (2) is inserted in the outside of stake (6), pile pulling collateral resistance is born primarily of steel pipe sleeve (2), therefore pile pulling difficulty of construction is greatly reduced, and by vibrating the mode of steel pipe sleeve (2), pile pulling collateral resistance is significantly reduced.After pile pulling completes, in order to avoid surface collapse, the space that easy filling pile pulling in time stays.At the sidewall of steel pipe sleeve (2), Grouting Pipe can be installed, realize synchronously carrying out hole backfill construction in pile pulling process, and grouting pressure can be utilized as a part for pile pulling power, counter-force pile-pulling construction method can also be pressed to complete micro-disturbance pile pulling construction with hole.Slip casting slurries used can be the materials such as cement paste, mortar.
This patent includes but not limited to other construction methods of the alternative use of professional person in this area.
