Abstract

The invention discloses a pile foundation construction technology of construction trade, in particular to a colligation and installation construction method of the artificial excavating pile reinforcing cage on an orifice of a caisson. The pile foundation construction technology is the improvement of the colligation and installation construction method of the current artificial excavating pile reinforcing cage. The vertical reinforcing cage manufacturing and installation method is adopted at the orifice of the artificial excavating pile which is provided with artificially formed pores and inspected to be qualified. The reinforcing cage is being manufactured as well as being installed. The manufacturing in sections is adopted. One section is installed after being manufactured until the design requirement is achieved. The artificial excavating pile reinforcing cage vertical colligation and installation method has the beneficial effects that: no mechanical equipment is required for installing the reinforcing cage when the method is compared with a present method, and the engineering cost can be reduced; large manufacturing and piling field is not required, therefore, the method is especially applied to narrow construction field; when the time limit for a project is nervous, piles can be manufactured and installed simultaneously as long as adequate manpower is supplied.

Description

Artificial excavating pile reinforcing cage vertical colligation and installation method
Technical field
The present invention relates to the construction technology of a kind of pile foundation of building trade.It specifically is the manually digging hole pile cages carries out vertical colligation and installs in the aperture construction method.Be to the colligation of existing manually digging hole pile cages and the improvement of construction method of installation.
Background technology
At present, existing manually digging hole pile cages is transported to on-the-spot the installation mostly after factory's colligation is good, promptly in the workshop or on-the-spot steel reinforcement cage is crouched putting colligation, be transported to the well head of artificial digging pile then, with crane gear steel reinforcement cage is hung vertical state again, arrive hand excavation's wellhole the inside down, make placement of cage of reinforcing bar.Perhaps install after the colligation moulding at the scene.Because (general 0.80m~3.00m), length is (general 5m~30m), when toward well is interior steel reinforcement cage being installed, need reinforcement cage hoisting be installed with hoisting machinery also greatly greatly for the steel reinforcement cage diameter; Adopt crane gear that steel reinforcement cage is installed, increased engineering cost.Particularly crane gear can't be adopted in some job site, during as construction artificial digging pile in deep basal pit, just makes the installation steel reinforcement cage cause difficulty.
Summary of the invention
For addressing the above problem, the invention provides vertical making of a kind of manually digging hole pile cages and installation method, steel reinforcement cage is carried out vertical colligation at well head, install on colligation limit, limit, does not need crane gear.
The present invention realizes with following technical scheme: vertical making of a kind of manually digging hole pile cages and installation method is characterized in that; The manual pore-forming and through making steel reinforcement cage on one side on the artificial digging pile aperture of acceptance(check), simultaneously steel reinforcement cage to be installed, concrete grammar is:
1) at two cross-arm that keep at a certain distance away of artificial digging pile well head horizontal positioned of acceptance(check);
2) keep flat the steel reinforcement cage of making on cross-arm and strengthen stirrup, and carry out five equilibrium to strengthening stirrup, isodisperse is identical with steel reinforcement cage master muscle quantity, carries out mark;
3) first road is measured and marked to steel reinforcement cage master muscle and strengthen the stirrup position, with strengthen that 2 of the basic symmetry of stirrup intersect vertically with two main muscle and main muscle outside, strengthen stirrup inside, and firm welding;
4) upwards two meters are firm with reinforcement stirrup means of spot welds with main muscle with identical method at main muscle; According to the method main muscle is installed in by root and strengthens on the stirrup;
5) weld firmly according to designing requirement winding screw stirrup and with tie hoop and main muscle contact point in main muscle outside;
6) with the pad place of two respectively firm bolt knots of soft rope in two symmetries of steel reinforcement cage both sides and main muscle and reinforcement stirrup;
7) manually hold the rope made of hemp, take out the cross-arm that is placed on well head, loosen the rope made of hemp gently, the first segment steel reinforcement cage is slowly fallen, when the reinforcement stirrup suitable for reading of first segment steel reinforcement cage drops down onto well head, stop to fall;
Put two cross-arms at well head then, set by step 1 to next joint steel reinforcement cage of the method fabrication and installation of step 7, so carry out, till reaching the designing requirement degree of depth according to the front.
The invention has the beneficial effects as follows: can steel reinforcement cage be installed without plant equipment with existing method comparison, engineering cost is reduced; Do not need very big making to stack the place, this is especially suitable to narrow construction site; When the duration is nervous, if the staff abundance, the fabrication and installation simultaneously of each position;

The specific embodiment
Embodiment
Present embodiment is finished as shown in Figure 1 and the artificial digging pile wellbore depth h of process acceptance(check) is 30m, and well head retaining wall 1 is arranged.Design is that the good 2m of every colligation is once saving to whereabouts 2m, until colligation be in place.In order to guarantee construction safety, a safety guard 6 is laid at the place in the aperture.Concrete grammar is:
1) as shown in Figure 2, the steel pipe of two diameter 48mm of horizontal positioned is made cross-arm 2 on the artificial digging pile well head, and cross-arm 2 also can be with the reinforcing bar of diameter 〉=25mm and other wooden class, bamboo class club.Distance is about 1/3 of a well head diameter between two steel pipes.
2) as shown in Figure 3, keep flat the steel reinforcement cage of making and strengthen stirrup 3 on steel pipe, and carry out five equilibrium to strengthening stirrup shown in Fig. 3-1, isodisperse is identical with steel reinforcement cage master muscle quantity, and carries out mark;
3) first road is measured and marked to steel reinforcement cage master muscle and strengthen the stirrup position, with strengthen that 2 of basic symmetry on the stirrup intersect vertically with two main muscle and main muscle outside, strengthen stirrup inside, and firm welding;
4) as shown in Figure 3, main muscle 4 upwards two meters with identical method with main muscle and reinforcement stirrup firm welding; According to the method main muscle 4 is installed in by root and strengthens on the stirrup 3;
5) weld firmly according to designing requirement winding screw stirrup 5 and with tie hoop 5 and main muscle 4 contact points as shown in Figure 4, in main muscle outside;
6) with the pad place of two ropes, 7 respectively firm bolt knots in two symmetries of steel reinforcement cage both sides and main muscle and reinforcement stirrup;
7) manually hold rope, take out the steel pipe that is placed on well head, slowly loosen the rope made of hemp, first section steel reinforcement cage slowly fallen, when when the reinforcement stirrup of two meters eminences arrives well head, stopping to fall originally.
State during then by beginning is put two steel pipes at well head, according to foregoing next section of method fabrication and installation steel reinforcement cage, till reaching the projected depth requirement, sees Fig. 5.
About safety guard: construction method provided by the invention, maximum hidden danger is that well head falls, and is especially before steel reinforcement cage is not shaped, dangerous especially.For addressing this problem, the present invention has designed a cover safety guard 6.Shown in Fig. 6-1, safety guard 6 is made up of two semicircle grids that reinforcing bar is processed into.By field fabrication and installation.Why making two semicircles, mainly is to consider that installation and removal are convenient.Using method is to place it in above the cross-arm, now extracts safety guard 6 when extracting cross-arm out out.
