Abstract
The utility model relates to a pile pulling cage of a bamboo-mattress pile, which comprises a channel steel and a lace bar and is characterized in that: two channel steels are parallel arranged with face-to-face notches, flush head parts, different tail parts in different lengths and two sides of the two channel steels are fixed by lace bars connected to form a pile cage; lace bars are spacedly erected to a front section of a tail part along the two sides of the channel steels and oblique lace bars are fixedly connected between two erected lace bars; two sides of the tail parts of the two channel steels are connected by the lace bars crossly and fixedly. The pile formation cage is formed by channel steels and lace bars, so the bamboo-mattress pile and a surrounding silt can be pulled out by the means of the friction of steel plates, silt and bamboo-mattress as long as the pile cage is sleeved at the position of the bamboo-mattress, thus solving the difficulty of poor anti-pulling performance of the bamboo mattress.
Description
Technical field
The utility model relates to the pile pulling cage that uses in a kind of building operations, especially a kind of pile pulling cage that is used for bamboo raft dowel.
Background technology
The international harbour affairs of international bus hub building, PORT OF SHANGHAI is located in port, the Gaoyang harbour that is built in 1825, and through several generations' transformation, reinforcing and use, geological conditions is quite complicated.When engineering is gone along with sb. to guard him construction, in underground discovery bamboo raft dowel (shown in Figure 1).This employing bamboo raft 1 replaces the vertical reinforcement of engineering piles, and galvanized wire 2 replaces the stirrup of engineering piles, and its inside is concrete 3.Because the tensile property of bamboo raft dowel is poor, common pile pulling means easily cause the bamboo raft dowel fracture.
Summary of the invention
The utility model is the pile pulling technology problem that will solve bamboo raft dowel, and a kind of pile pulling cage that is used for bamboo raft dowel is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of bamboo raft dowel pile pulling cage comprises channel-section steel, and lacing is characterized in: two channel-section steel recesses are arranged in parallel face-to-face, and head flushes, and afterbody has length difference, and both sides are with the fixedly connected pile cage of lacing.
Lacing is erect along the both sides of channel-section steel and is spaced to afterbody the last period, erects between the lacing at two and is fixedly connected with oblique lacing; The place, afterbody both sides of two channel-section steels connects with the lacing cross fixation.
The utility model is owing to adopted channel-section steel and a lacing composition stake cage, extractor is as long as be inserted in the bamboo raft dowel position with the stake cage, utilize steel plate, mud just bamboo raft dowel and the mud around it can be extracted, solved the difficult point of bamboo raft dowel tensile property difference with the frictional force of bamboo raft dowel.
Description of drawings
Fig. 1 is the schematic cross-section of bamboo raft dowel;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the utility model schematic cross-section.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As Fig. 2, shown in 3, bamboo raft dowel pile pulling cage of the present utility model is made of channel-section steel 10 and lacing 20.Two channel-section steel 10 recesses are arranged in parallel face-to-face, and head flushes, and afterbody has length difference, and promptly channel-section steel 10 length are greater than the length of another root channel-section steel 10, and the both sides of two channel-section steels 10 are fixedly connected into the stake cage that can be inserted in bamboo raft dowel with lacing 20 welding.
Lacing 20 is erect along the both sides of channel-section steel 10 and is spaced to afterbody the last period, erects between the lacing 20 with oblique lacing 30 fixedly connected at two.The place, afterbody both sides of two channel-section steels 10 connects with oblique lacing 40 cross fixation.
When the utility model used, extractor inserted in the mud of bamboo raft dowel periphery with channel-section steel earlier and loosens the soil, and after plug for several times, bamboo raft dowel descends with the bonding force of the mud of periphery.Extractor utilizes the pile pulling cage to be inserted in the bamboo raft dowel position again, utilizes the principle of the frictional force of steel plate, mud and bamboo raft dowel, and bamboo raft dowel and the mud around it are extracted together.Can successfully solve the difficult point of bamboo raft dowel tensile property difference.
