Abstract
The invention discloses a combined anchor-rod static pressure pile which has the advantages of a precast concrete pile and a steel pipe pile. The combined anchor rod static pressure pile is characterized in that a pile body is composed of an upper precast concrete pile and a lower steel pipe pile; and in the process of preparing the combined anchor rod static pressure pile, a pile sinking construction process is implemented by using an anchor rod static pressure method, and comprises the following steps: pressing the steel pipe pile part of the combined pile, carrying out construction on a joint of the precast concrete pile and the steel pipe pile; and pressing the precast concrete pile part of the combined pile. The combined anchor rod static pressure pile provided by the invention has the advantages of high bearing capacity of single pile, good quality of pile body, economical cost of construction, and small compaction effect and environmental hazard in the process of pile sinking construction, and the like, therefore, the combined anchor rod static pressure pile is suitable for the underpinning and reinforcement of foundations of the existing buildings.
Description
Technical field
The present invention relates to the civil engineering building engineering field, and relate in particular to a kind of anchor rod static pressure compound pile that is applicable to that the existing building foundation underpinning is reinforced, its pile body is formed by connecting by the precast concrete pile on top and the steel pipe pile of bottom, and adopts anchor rod static pressure method construction technology pile sinking.
Background technology
Anchor jacked pile has that construction equipment is light, simple, the operating space is little, friction, noiselessness, the stressed advantage that clearly waits in the work progress, is used widely in existing building foundation underpinning engineering.Anchor jacked pile stake type generally adopts precast concrete pile or steel pipe pile.The precast concrete pile capacity is higher, pile quality good and cost is cheap relatively, but when construction soil compaction effect obviously, have greater environmental impacts, when environmental protection requirement is high, use to be restricted.Steel pipe pile has that bearing capacity of single pile is higher, pile quality better, advantage such as especially soil compaction effect is little during pile sinking, environmental hazards is little, but its expense is higher relatively, has limited its application in a wider context to a certain extent.The present invention proposes a kind of new stake type---anchor rod static pressure compound pile with precast concrete pile and steel pipe pile advantage.
Summary of the invention
The above-mentioned precast concrete pile soil compaction effect of mentioning is big in order to solve, the relative problem of higher of steel pipe pile expense, the invention provides a kind of cost than steel pipe pile economy, soil compaction effect and steel pipe pile are suitable, little than precast concrete pile, environmental hazards is little, bearing capacity and quality all are applicable to the anchor rod static pressure compound pile that the existing building foundation underpinning is reinforced preferably, its pile body is formed by connecting by the precast concrete pile on top and the steel pipe pile of bottom, and adopts anchor rod static pressure method construction technology pile sinking.
Further, above-mentioned anchor rod static pressure compound pile adopts anchor rod static pressure method construction technology pile sinking, may further comprise the steps: be pressed into the steel pipe pile part of compound pile, construction precast concrete pile and steel pipe pile joint; Be pressed into the precast concrete pile part of compound pile.
Further, described compound pile pile sinking adopts piling equipment, and it comprises the electric block on top, and the combination of counter-force and jack also is fixed on the basis by anchor pole, thereby the steel pipe pile part of compound pile is pressed in the foundation soil by the piling hole.
Further, the joint of described precast concrete pile and steel pipe pile by steel pipe pile with and go up the polylith steel plate and be welded, described steel pipe pile links together by joint and concrete pile.
Further, the described precast concrete pile part that is pressed into compound pile is sealed the stake processing to design elevation.
A kind of pile body provided by the invention is formed by connecting by the precast concrete pile on top and the steel pipe pile of bottom, and the anchor rod static pressure compound pile of employing anchor rod static pressure method construction technology pile sinking, compound pile pile body provided by the invention is to be formed by connecting by joint by the precast concrete pile on top and the steel pipe pile of bottom, its cost is suitable, little than precast concrete pile than steel pipe pile economy, soil compaction effect and steel pipe pile, environmental hazards is little, is convenient to use in urban construction existing building strengthening reconstruction.
