Abstract
The invention relates to a prestressed reinforcement and non-prestressed reinforcement combined H-shaped reinforced concrete sheet pile and a manufacture method thereof. The H-shaped reinforced concrete sheet pile adopts an I-shaped structure; and prestressed reinforcement and non-prestressed reinforcement are arranged in the H-shaped reinforced concrete sheet pile at the same time. Compared with the prior art, the H-shaped reinforced concrete sheet pile has the advantages of good bending resistance and shearing resistance, low cost, high efficiency, zero contamination, environmental protection and the like.
Description
Technical field
The present invention relates to a kind of H type steel bar concrete sheet pile, especially relate to the H type steel bar concrete sheet pile of a kind of prestressing force and non-prestressed combination.
Background technology
In civilian and industrial construction, the bracing of foundation pit majority adopts following several method at present:
1. insert H shaped steel in the employing cement mixing method as sealing and retaining soil, H shaped steel majority is lease, and the time, long more rent was high more, and some location does not have the position to stop crane in addition, so shaped steel just can not pull out, cost is higher, and rate are bigger.
2. adopt bored pile retaining soil, the cement mixing method sealing, cost is high, waste is big, and the mud contamination environment is arranged again.
3. adopt many drainings earth agitation pile---gravity dam, as sealing retaining soil, to be that peripheral space is big could implement prerequisite, but can not going along with sb. to guard him as deep foundation ditch.
Summary of the invention
The object of the invention be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of bending resistance shear behavior is good, cost is low, effect is high, pollution-free, the H type steel bar concrete sheet pile of the prestressing force of environmental protection and non-prestressed combination again.
The object of the invention can be realized through following technical scheme: the H type steel bar concrete sheet pile of a kind of prestressing force and non-prestressed combination; This H type steel bar concrete sheet pile is " worker " font reinforced concrete slab pilework; It is characterized in that, dispose prestressed reinforcement and nonprestressed reinforcement simultaneously in the described H type steel bar concrete sheet pile.
Described prestressed reinforcement and nonprestressed reinforcement are provided with many, are evenly distributed on respectively in the H type steel bar concrete sheet pile.
Described H type steel bar concrete sheet pile is divided into more piece, and each saves the joint embedded iron is set, and to the building site, adopts steel plate or angle steel to splice connection.
Through welding between the embedded iron separately, satisfy the needs that ultra-deep foundation pit is gone along with sb. to guard him between the more piece H type steel bar concrete sheet pile.
The manufacturing approach of the H type steel bar concrete sheet pile of a kind of prestressing force and non-prestressed combination; It is characterized in that this method is after the nonprestressed reinforcement colligation is accomplished, pre-buried again prestressed reinforcement and embedded iron; Disturbing concrete again; Maintenance waits concrete strength to reach after 70～100% the pre-buried prestressed reinforcement of stretch-draw again, and anchoring gets final product after accomplishing.
The embedded iron at described nonprestressed reinforcement and pile cover place is directly welded.
Described prestressed reinforcement is anchored on two pile covers.
Compared with prior art, the present invention has the following advantages:
1. prestressing force and non-prestressed H type steel bar concrete sheet pile, it has improved the rigidity of sheet pile, has increased the durability of sheet pile, has reduced vibration and elastic deformation, has strengthened the bending resistance shear behavior.Extra-Deep Foundation Pit adopts prestressing force and non-prestressed H type steel bar concrete sheet pile, can reduce the deflection of foundation ditch greatly.
2. native with the slotting H shaped steel in cement-soil and the bored pile retaining of routine, the cement-soil stirring water-stop is compared, and 30-40% can reduce cost.
3.H type steel bar concrete sheet pile is batch production production, to field Welding, length controlled is used for underground four layers (20 meters) Extra-Deep Foundation Pit engineering of foundation ditch, is widely used.
4.H type steel bar concrete sheet pile is that factory is customized, to on-the-spot just welding, inserts then in the cement mixing method, and pollution-free no mud, the duration shortens greatly, and the civilized construction degree is high.
5. because nonprestressed reinforcement directly is welded on the embedded iron of pile cover, guaranteed the switching performance of joint stake up and down, the tensile property of joint area is guaranteed.
